Recommended target dosage: 20 mg to 40 mg once daily with food (2.1, 12.3)

To titrate: start with initial dosage of 10 mg once daily for 7 days, followed by 20 mg once daily. The dose may be increased up to 40 mg once daily after a minimum of 7 days between dosage increases (2.1)

Prior to initiating Vilazodone, screen for bipolar disorder (2.2, 5.4)

When discontinuing Vilazodone, reduce dosage gradually (2.4, 5.5)

The recommended target dosage for vilazodone is 20 mg to 40 mg orally once daily with food [ see Clinical Pharmacology ( 12.3 ) , Clinical Studies ( 14 ) ]. To achieve the target dosage, titrate vilazodone as follows:

Start with an initial dosage of 10 mg once daily with food for 7 days,

Then increase to 20 mg once daily with food.

The dose may be increased up to 40 mg once daily with food after a minimum of 7 days between dosage increases.

If a dose is missed, it should be taken as soon as the patient remembers. If it is almost time for the next dose, the patient should skip the missed dose and take the next dose at the regular time. Two doses should not be taken at the same time.

Prior to initiating treatment with vilazodone or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions ( 5.4 )] .

At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI) antidepressant and initiation of vilazodone. In addition, at least 14 days must elapse after stopping vilazodone before starting an MAOI antidepressant [see Contraindications ( 4 ), Warnings and Precautions ( 5.2 ) ].

Patients receiving concomitant CYP3A4 inhibitors:

During concomitant use of a strong CYP3A4 inhibitor (e.g., itraconazole, clarithromycin, voriconazole), the vilazodone dose should not exceed 20 mg once daily. The original vilazodone dose level, can be resumed when the CYP3A4 inhibitor is discontinued [see Drug Interactions ( 7 )].

Patients receiving concomitant CYP3A4 inducers:

Based on clinical response, consider increasing the dosage of vilazodone by 2-fold, up to a maximum 80 mg once daily, over 1 to 2 weeks in patients taking strong CYP3A4 inducers (e.g., carbamazepine, phenytoin, rifampin) for greater than 14 days. If CYP3A4 inducers are discontinued, gradually reduce the vilazodone dosage to its original level over 1 to 2 weeks [see Drug Interactions ( 7 )].

Adverse reactions may occur upon discontinuation of vilazodone [see Warnings and Precautions ( 5.5 )]. A gradual reduction in dosage rather than abrupt cessation is recommended whenever possible. vilazodone should be down tapered from the 40 mg once daily dose to 20 mg once daily for 4 days, followed by 10 mg once daily for 3 days. Patients taking vilazodone 20 mg once daily should be tapered to 10 mg once daily for 7 days.

Vilazodone is contraindicated in:

Patients taking, or within 14 days of stopping, monoamine oxidase inhibitors (MAOIs), including MAOIs such as linezolid or intravenous methylene blue, because of an increased risk of serotonin syndrome [see Warnings and Precautions ( 5.2 ) , Drug Interactions ( 7 ) ].

Concomitant use of monoamine oxidase inhibitors (MAOIs), or use within 14 days of stopping MAOIs (4)

5

Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents (e.g., SSRI, SNRI, triptans, amphetamines), but also when taken alone. If it occurs, discontinue Vilazodone and initiate supportive treatment (5.2)

Increased Risk of Bleeding: Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), other antiplatelet drugs, warfarin, and other anticoagulants may increase this risk (5.3)

Activation of Mania/Hypomania: Screen patients for bipolar disorder (5.4).

Seizures: Can occur with treatment. Use with caution in patients with a seizure disorder (5.6).

Angle Closure Glaucoma: Avoid use of antidepressants, including Vilazodone, in patients with untreated anatomically narrow angles. (5.7)

Sexual Dysfunction: Vilazodone may cause symptoms of sexual dysfunction (5.9)

In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients, and over 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in antidepressant-treated patients age 24 years and younger was greater in antidepressant-treated patients than in placebo-treated patients. There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied. There were differences in absolute risk of suicidal thoughts and behaviors across the different indications, with the highest incidence in patients with MDD. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1000 patients treated are provided in Table 1.

Table 1: Risk Differences of the Number of Patients with Suicidal Thoughts or Behaviors in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult Patients

Increases Compared to Placebo

<18 14 additional patients

18-24 5 additional patients

25-64 1 fewer patient

≥65 6 fewer patients

It is unknown whether the risk of suicidal thoughts and behaviors in children, adolescents, and young adults extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance studies in adults with MDD that antidepressants delay the recurrence of depression and that depression itself is a risk factor for suicidal thoughts and behaviors.

Monitor all antidepressant-treated patients for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing vilazodone, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.

Serotonin and norepinephrine reuptake inhibitors (SNRIs) and selective serotonin reuptake inhibitor (SSRIs), including vilazodone, can precipitate serotonin syndrome, a potentially life-threatening condition. The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St. John’s Wort) and with drugs that impair metabolism of serotonin, i.e., MAOIs [see Contraindications ( 4 ) and Drug Interactions ( 7 )]. Serotonin syndrome can also occur when these drugs are used alone. Symptoms of serotonin syndrome were noted in 0.1% of MDD patients treated with vilazodone in premarketing clinical trials.

Serotonin syndrome signs and symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).

The concomitant use of vilazodone with MAOIs is contraindicated. In addition, do not initiate vilazodone in a patient being treated with MAOIs such as linezolid or intravenous methylene blue. No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection). If it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking vilazodone, discontinue vilazodone before initiating treatment with the MAOI [ see Contraindications ( 4 ) , Drug Interactions ( 7.1 ) ].

Monitor all patients taking vilazodone for the emergence of serotonin syndrome. Discontinue treatment with vilazodone and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of vilazodone with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

Drugs that interfere with serotonin reuptake inhibition, including vilazodone, increase the risk of bleeding events. Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDS), other antiplatelet drugs, warfarin, and other anticoagulants may add to this risk. Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Bleeding events related to drugs that interfere with serotonin reuptake have ranged from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages.

Inform patients about the risk of bleeding associated with the concomitant use of vilazodone and antiplatelet agents or anticoagulants. For patients taking warfarin, carefully monitor coagulation indices when initiating, titrating, or discontinuing vilazodone.

In patients with bipolar disorder, treating a depressive episode with vilazodone or another antidepressant may precipitate a mixed/manic episode. In controlled clinical trials, patients with bipolar disorder were excluded; however, symptoms of mania or hypomania were reported in 0.1% of undiagnosed patients treated with vilazodone. Prior to initiating treatment with vilazodone, screen patients for any personal or family history of bipolar disorder, mania, or hypomania [see Dosage and Administration ( 2.2 )].

Adverse reactions after discontinuation of serotonergic antidepressants, particularly after abrupt discontinuation, include: nausea, sweating, dysphoric mood, irritability, agitation, dizziness, sensory disturbances (e.g., paresthesia, such as electric shock sensations), tremor, anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, and seizures. A gradual reduction in dosage rather than abrupt cessation is recommended whenever possible [see Dosage and Administration ( 2.5 )].

Vilazodone has not been systematically evaluated in patients with a seizure disorder. Patients with a history of seizures were excluded from clinical studies. Vilazodone should be prescribed with caution in patients with a seizure disorder.

The pupillary dilation that occurs following use of many antidepressant drugs including vilazodone may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy. Avoid use of antidepressants, including vilazodone, in patients with untreated anatomically narrow angles.

Hyponatremia may occur as a result of treatment with SNRIs and SSRIs, including vilazodone. Cases of serum sodium lower than 110 mmol/L have been reported. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls. Signs and symptoms associated with more severe and/or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death. In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH).

In patients with symptomatic hyponatremia, discontinue vilazodone and institute appropriate medical intervention. Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia with SSRIs and SNRIs [see Use in Specific Populations ( 8.5 )].

Use of SSRIs, including vilazodone, may cause symptoms of sexual dysfunction [ see Adverse Reactions ( 6.1 )]. In male patients, SSRI use may result in ejaculatory delay or failure, decreased libido, and erectile dysfunction. In female patients, SSRI use may result in decreased libido and delayed or absent orgasm.

It is important for prescribers to inquire about sexual function prior to initiation of vilazodone and to inquire specifically about changes in sexual function during treatment, because sexual function may not be spontaneously reported. When evaluating changes in sexual function, obtaining a detailed history (including timing of symptom onset) is important because sexual symptoms may have other causes, including the underlying psychiatric disorder. Discuss potential management strategies to support patients in making informed decisions about treatment.

CLINICAL TRIALS EXPERIENCE SECTION

Because clinical trials are conducted under widely varying conditions and varying lengths of time, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect rates observed in practice.

The most commonly observed adverse reactions in vilazodone -treated patients with major depressive disorder (MDD) in placebo-controlled studies (incidence ≥ 5% and at least twice the rate of placebo) were diarrhea, nausea, vomiting, and insomnia.

Patient Exposure

The safety of vilazodone was evaluated in 3,007 patients (18-70 years of age) diagnosed with MDD who participated in clinical studies, representing 676 patient-years of exposure. In an open-label 52 week study at 40 mg daily, 599 patients were exposed to vilazodone for a total of 348 patient-years.

The adverse reaction information presented below was derived from studies of vilazodone 20 mg and 40 mg daily in patients with MDD including:

Four placebo-controlled 8 to 10-week studies in 2,233 patients, including 1,266 vilazodone -treated patients; and

An open-label 52-week study of 599 vilazodone -treated patients.

These studies included a titration period of 10 mg daily for 7 days, followed by 20 mg daily for 7 days or to 40 mg daily over 2 weeks. In these clinical trials, vilazodone was administered with food.

Adverse reactions reported as reasons for discontinuation of treatment

In these studies, 7.3% of the vilazodone -treated patients discontinued treatment due to an adverse reaction, compared with 3.5% of placebo-treated patients. The most common adverse reaction leading to discontinuation in at least 1% of the vilazodone -treated patients in the placebo-controlled studies was nausea (1.4%).

Common adverse reactions in placebo-controlled MDD studies

Table 2 shows the incidence of common adverse reactions occurring in ≥ 2% of vilazodone -treated patients and greater than the rate of placebo-treated patients in MDD Studies.  There were no dose-related adverse reactions between 20 mg and 40 mg reported.

      Psychiatric disorders: infrequent: panic attack

      Skin and subcutaneous tissue disorders: in frequent: hyperhidrosis, night sweats

POSTMARKETING EXPERIENCE SECTION

The following adverse reactions have been identified during post-approval use of vilazodone. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or establish a causal relationship to drug exposure. Reports of adverse reactions temporally associated with vilazodone that have been received since market introduction and that are not uled above include the following:

General Disorders and Administration Site Conditions: irritabilityNervous System Disorders: sleep paralysisPsychiatric Disorders: hallucinations, suicide attempt, suicidal ideationSkin and subcutaneous tissue disorders: rash, generalized rash, urticaria, drug eruption Gastrointestinal System: acute pancreatitis

7

CYP3A4 Inhibitors: The Vilazodone dose should not exceed 20 mg once daily when co-administered with strong CYP3A4 inhibitors (2.4, 7).

CYP3A4 Inducers: Consider increasing Vilazodone dosage by 2-fold, up to 80 mg once-daily over 1 to 2 weeks when used concomitantly with strong CYP3A4 inducers for greater than 14 days (2.4, 7).

Table 4: Clinically Important Drug Interactions with Vilazodone

Concomitant Drug Name or Drug Class Clinical Rationale Clinical Recommendation

Monoamine Oxidase Inhibitors (MAOIs) The concomitant use of MAOIs and serotonergic drugs including vilazodone increases the risk of serotonin syndrome. Vilazodone is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Contraindications ( 4 ), Dos age and Administration ( 2.3 ) , and Warnings and Precautions ( 5.2 )].

Other Serotonergic Drugs The concomitant use of serotonergic drugs including vilazodone and other serotonergic drugs increases the risk of serotonin syndrome. Monitor patients for signs and symptoms of serotonin syndrome, particularly during vilazodone initiation. If serotonin syndrome occurs, consider discontinuation of vilazodone and/or concomitant serotonergic drugs [see Warnings and Precautions ( 5.2 )].

Antiplatelet Agents and Anticoagulants Serotonin release by platelets plays an important role in hemostasis. The concurrent use of an antiplatelet agent or anticoagulant with vilazodone may potentiate the risk of bleeding. Inform patients of the increased risk of bleeding with the concomitant use of vilazodone and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio (INR) when initiating, titrating, or discontinuing vilazodone [see Warnings and Precautions ( 5.3 )].

Strong CYP3A4 Inhibitors (e.g., itraconazole, clarithromycin, voriconazole) The concomitant use of vilazodone and strong CYP3A4 inhibitors increased the exposure of vilazodone compared to the use of vilazodone alone [see Clinical Pharmacology ( 12.3 )]. The vilazodone dose should not exceed 20 mg once daily with the concomitant use of a strong CYP3A4 inhibitor [see Dosage and Administration ( 2.4 ) , Clinical Pharmacology ( 12.3 ) ] .

Strong CYP3A4 Inducers (e.g., carbamazepine, phenytoin, rifampin) The concomitant use of vilazodone and strong CYP3A4 inducers decreased the exposure of vilazodone compared to the use of vilazodone alone [see Clinical Pharmacology ( 12.3 )]. Based on clinical response, consider increasing the dosage of vilazodone, over 1 to 2 weeks in patients taking strong CYP3A4 inducers for greater than 14 days [see Dosage and Administration ( 2.4 ) , Clinical Pharmacology ( 12.3 ) ].

Digoxin Digoxin is a narrow therapeutic index drug. Concomitant use of vilazodone increased digoxin concentrations [see Clinical Pharmacology ( 12.3 )]. Measure serum digoxin concentrations before initiating concomitant use of vilazodone. Continue monitoring and reduce digoxin dose as necessary.

Based on pharmacokinetic studies, no dosage adjustment is required for drugs that are substrates of CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4, and/or P-glycoprotein (except narrow therapeutic index drugs, e.g., digoxin), when vilazodone is administered concomitantly [see Drug Interactions ( 7.1 ), Clinical Pharmacology ( 12.3 )].

8

Pregnancy: Third trimester use may increase risk for persistent pulmonary hypertension and withdrawal in the newborn (8.1).

PREGNANCY SECTION

Pregnancy Exposure Registry

There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/.

Risk Summary

There are no adequate and well-controlled studies of vilazodone in pregnant women. The background risk of major birth defects and miscarriage for the indicated population is unknown. However, the background risk in the U.S. general population of major birth defects is 2-4% and of miscarriage is 15-20% of clinically recognized pregnancies. In animal reproduction studies, oral administration of vilazodone during the period of organogenesis at doses up to 48 and 17 times the maximum recommended human dose (MRHD) in rats and rabbits, respectively, resulted in decreased fetal body weight gain and delayed skeletal ossification but no teratogenic effects were observed. Decreased fetal body weight and delayed skeletal ossification were not observed at doses up to 10 and 4 times the MRHD in rats and rabbits, respectively [see Data ] .

Clinical Considerations

Disease-associated m aternal and/or e mbryo/ f etal r isk

A prospective, longitudinal study followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. The women who discontinued antidepressants during pregnancy were more likely to experience a relapse of major depression than women who continued antidepressants. Consider the risks of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum.

Fetal/Neonatal adverse reactions

Exposure to SSRIs and SNRIs, including vilazodone, in late pregnancy may lead to an increased risk for neonatal complications requiring prolonged hospitalization, respiratory support, and tube feeding, and/or persistent pulmonary hypertension of the newborn (PPHN). Monitor neonates who were exposed to vilazodone in the third trimester of pregnancy for PPHN and drug discontinuation syndrome [see Data )].

Data

Human Data

Third Trimester Exposure

Neonates exposed to SSRIs or SNRIs late in the third trimester, have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. These findings are based on post-marketing reports. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. These features are consistent with either a direct toxic effect of SSRIs and SNRIs or, possibly, a drug discontinuation syndrome. In some cases, the clinical picture was consistent with serotonin syndrome [see Warnings and Precautions ( 5.2 )].

Exposure during late pregnancy to SSRIs may have an increased risk for persistent pulmonary hypertension of the newborn (PPHN). PPHN occurs in 1-2 per 1,000 live births in the general population and is associated with substantial neonatal morbidity and mortality. In a retrospective case-control study of 377 women whose infants were born with PPHN and 836 women whose infants were born healthy, the risk for developing PPHN was approximately six-fold higher for infants exposed to SSRIs after the 20th week of gestation compared to infants who had not been exposed to antidepressants during pregnancy. A study of 831,324 infants born in Sweden in 1997-2005 found a PPHN risk ratio of 2.4 (95% CI 1.2-4.3) associated with patient-reported maternal use of SSRIs "in early pregnancy" and a PPHN risk ratio of 3.6 (95% CI 1.2-8.3) associated with a combination of patient-reported maternal use of SSRIs "in early pregnancy" and an antenatal SSRI prescription "in later pregnancy."

Animal Data

No teratogenic effects were observed when vilazodone was given to pregnant rats or rabbits during the period of organogenesis at oral doses up to 200 and 36 mg/kg/day, respectively. These doses are 48 and 17 times, in rats and rabbits, respectively, the maximum recommended human dose (MRHD) of 40 mg on a mg/m² basis. Fetal body weight gain was reduced, and skeletal ossification was delayed in both rats and rabbits at these doses; these effects were not observed at doses up to 10 times the MRHD in rats or 4 times the MRHD in rabbits.

When vilazodone was administered to pregnant rats at an oral dose of 30 times the MRHD during the period of organogenesis and throughout pregnancy and lactation, the number of live born pups was decreased. There was an increase in early postnatal pup mortality, and among surviving pups there was decreased body weight, delayed maturation, and decreased fertility in adulthood. There was some maternal toxicity at this dose. These effects were not seen at 6 times the MRHD.

LACTATION SECTION

Risk Summary

There are no data on the presence of vilazodone in human milk, the effects of vilazodone on the breastfed infant, or the effects of the drug on milk production. However, vilazodone is excreted in rat milk [see Data ]. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for vilazodone and any potential adverse effects on the breastfed child from vilazodone or from the underlying maternal condition.

Data

Animal Data

Administration of vilazodone to lactating rats at an oral dose of 30 times the maximum recommended human dose (MRHD), resulted in early postnatal pup mortality, and among surviving pups there was decreased body weight and delayed maturation.

PEDIATRIC USE SECTION

The safety and effectiveness of vilazodone have not been established in pediatric patients for the treatment of MDD.

Efficacy was not demonstrated in two adequate and well controlled, 8-week studies including a total of 1002 pediatric patients ages 7 years to 17 years of age with MDD. The following adverse reactions were reported in at least 5% of pediatric patients treated with vilazodone and occurred at a rate at least twice that for pediatric patients receiving placebo: nausea, vomiting, diarrhea, abdominal pain/discomfort, and dizziness.

Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see Boxed Warning , Warnings and Precautions ( 5.1 ) , and Adverse Reactions ( 6.2 ) ].

Juvenile Animal Toxicity Data

In a juvenile animal study, male and female rats were treated with vilazadone (10, 50, and 200 mg/kg/day) starting on postnatal day (PND) 21 through 90. A delay in the age of attainment of vaginal patency (i.e. sexual maturation) was observed in females starting at 50 mg/kg/day with a No Observed Adverse Effect Level (NOAEL) of 10 mg/kg/day. This NOAEL was associated with AUC levels similar to those measured at a maximum dose tested in pediatrics (30 mg). Adverse behavioral effects (lack of habituation in an acoustic startle test) were observed in males at 200 mg/kg and females starting at 50 mg/kg both during drug treatment and the recovery periods. The NOAEL for this finding was 50 mg/kg for males and 10 mg/kg for females, which was associated with AUC levels greater than (males) or similar (females), to those observed with the maximum dose tested in pediatric patients. An 8% decrease in femur mineral density was observed in female rats at 200 mg/kg, compared to the control group. The NOAEL for this finding was 50 mg/kg, which was associated with an AUC level greater than those measured at the maximum dose tested in pediatrics.

Based on a pharmacokinetic study, no dosage adjustment of vilazodone is recommended on the basis of age (see Figure 3). Results from pharmacokinetic study of a single 20 mg vilazodone dose in geriatric subjects (> 65 years-old) vs. younger subjects (24-55 years-old) demonstrated that the pharmacokinetics were generally similar between the two age groups [see Clinical Pharmacology ( 12.3 )].

Clinical studies of vilazodone did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Of the 3,007 patients in clinical studies with vilazodone, 65 (2.2%) were 65 years of age or older, and 378 (12.6%) were 55 to 64 years of age. In general, dose selection for an elderly patient should be conservative, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Serotonergic antidepressants have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse reaction [see Warnings and Precautions ( 5.8 )]. No other differences in adverse reactions were observed between geriatric and younger patients.

8.6

No dosage adjustment of vilazodone is necessary on the basis of gender, renal function (mild to severe renal impairment, glomerular filtration rate: 15-90 mL/minute), or hepatic function (mild to severe hepatic impairment, Child-Pugh score: 5-15 [see Clinical Pharmacology ( 12.3 )].

9.1

Vilazodone is not a controlled substance.

9.2

Vilazodone has been systematically studied in animals and did not demonstrate abuse or dependence potential. While vilazodone has not been systematically studied in humans for its potential for abuse, there was no suggested evidence of drug-seeking behavior in the clinical studies.

10

There is limited clinical trial experience regarding human overdose with vilazodone. The adverse reactions associated with overdose of vilazodone at doses of 200-280 mg (5 to 7 times the recommended dosage) as observed in clinical trials included serotonin syndrome, lethargy, restlessness, hallucinations, and disorientation.

For current information on the management of poisoning or overdose, contact a poison control center at 1-800-222-1222.

No specific antidotes for vilazodone are known. Removal of vilazodone by dialysis has not been studied; however, the high volume of distribution of vilazodone suggests that dialysis will not be effective in reducing vilazodone plasma concentrations.

11

VILAZODONE tablets for oral administration contain polymorph Form IV vilazodone hydrochloride (HCl), a selective serotonin reuptake inhibitor and a 5HT_1A receptor partial agonist.

Vilazodone HCl is 2-benzofurancarboxamide, 5-[4-[4-(5-cyano-1H-indol-3-yl)butyl]-1-piprazinyl]-, hydrochloride (1:1). Its molecular weight is 477.99. The structural formula is:

Vilazodone tablets are available as 10 mg, 20 mg, and 40 mg film-coated tablets containing 10 mg, 20 mg, and 40 mg of vilazodone HCl, respectively.

In addition to the active ingredient, vilazodone tablets contain the following inactive ingredients: colloidal silicon dioxide, lactose monohydrate, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polyvinyl alcohol, talc, titanium dioxide, FD&C Blue #1 (40 mg only), FD&C Red #40 (10 mg only), and FD&C Yellow #6 (20 mg only).

12

12.1

The mechanism of action of vilazodone in the treatment of major depressive disorder is not fully understood, but is thought to be related to its enhancement of serotonergic activity in the CNS through selective inhibition of serotonin reuptake. Vilazodone is also a partial agonist at serotonergic 5-HT_1A receptors; however, the net result of this action on serotonergic transmission and its role in vilazodone’s antidepressant effect are unknown.

12.2

Vilazodone binds with high affinity to the serotonin reuptake site (Ki= 0.1 nM), but not to the norepinephrine (Ki=56 nM) or dopamine (Ki=37 nM) reuptake sites. Vilazodone potently and selectively inhibits reuptake of serotonin (IC₅₀= 1.6 nM). Vilazodone also binds selectively with high affinity to 5-HT_1A receptors (IC₅₀=2.1 nM) and is a 5-HT_1A receptor partial agonist.

Cardiac Electrophysiology

Treatment with vilazodone did not prolong the QTc interval. The effect of vilazodone [20, 40, 60, and 80 mg (2 times the recommended dosage)] on the QTc interval was evaluated in a randomized, placebo-, and active-controlled (moxifloxacin 400 mg), parallel-group, thorough QTc study in 157 healthy subjects. The study demonstrated an ability to detect small effects. The upper bound of the 90% confidence interval for the largest placebo-adjusted, baseline-corrected QTc interval was below 10 msec, based on the individual correction method (QTcI). Thus, at doses of 2 times the recommended dosage, vilazodone did not prolong the QTc interval to a clinically relevant extent.

12.3

Vilazodone activity is due primarily to the parent drug. The pharmacokinetics of vilazodone (5 mg – 80 mg) are dose-proportional. Accumulation of vilazodone after administration of single vilazodone doses did not vary with dose, and steady-state was achieved in about 3 days. Elimination of vilazodone is primarily by hepatic metabolism with a terminal half-life of approximately 25 hours. At steady-state, after daily dosing of vilazodone 40 mg under fed conditions, the mean C_max value was 156 ng/mL, and the mean AUC (_{0-24 hours}) value was 1645 ng·h/mL.

Absorption

Vilazodone concentrations peaked at a median of 4-5 hours (T_max) after vilazodone administration and declined with a terminal half-life of approximately 25 hours. The absolute bioavailability of vilazodone was 72% with food. Vilazodone AUC and C_max in the fasted state can be decreased by approximately 50% and 60%, respectively, compared to the fed state. Administration without food can result in inadequate drug concentrations and may reduce effectiveness.

Coadministration of vilazodone with ethanol or with a proton pump inhibitor (pantoprazole) did not affect the rate or extent of vilazodone absorption. In addition, neither the T_max nor terminal elimination rate of vilazodone was altered by coadministration with either pantoprazole or ethanol.

Absorption is decreased by approximately 25% if vomiting occurs within 7 hours of ingestion; no replacement dose is needed.

Distribution

Vilazodone is widely distributed and approximately 96-99% protein-bound. Administration of vilazodone to a patient taking another drug that is highly protein bound may cause increased free concentrations of the other drug, because vilazodone is highly bound to plasma protein. The interaction between vilazodone and other highly protein-bound drugs has not been evaluated.

Metabolism and Elimination

Vilazodone is extensively metabolized through CYP and non-CYP pathways (possibly by carboxylesterase), with only 1% of the dose recovered in the urine and 2% of the dose recovered in the feces as unchanged vilazodone. CYP3A4 is primarily responsible for its metabolism among CYP pathways, with minor contributions from CYP2C19 and CYP2D6.

Drug Interaction Studies

Figure 1 below includes the impact of other drugs on the pharmacokinetics of vilazodone [see Drug Interactions ( 7 )].
Figure 1. Effect of Other Drugs on Vilazodone Pharmacokinetics
In vitro studies indicate that vilazodone is unlikely to inhibit or induce the metabolism of substrates for CYP1A1, 1A2, 2A6, 2B6, 2C9, 2C19, 2D6, 2E1, 3A4 or 3A5, except for CYP2C8. The effect of vilazodone on CYP2C8 activity has not been tested in vivo. Figure 2 below includes the impact of vilazadone on the pharmacokinetics of other drugs in vivo.
Figure 2. Impact of Vilazodone on Other Drug Pharmacokinetics
Studies in Specific Population s :

The presence of mild to severe renal impairment or mild to severe hepatic impairment did not affect the apparent clearance of vilazodone (see Figure 3). There were no pharmacokinetic differences of vilazodone in geriatric patients compared to younger patients, or between males and females (see Figure 3).
Figure 3: Impact of Intrinsic Factors on Vilazodone Pharmacokinetics

13.1

Carcinogenesis Carcinogenicity studies were conducted in which B6C3F1mice and Wistar rats were given oral doses of vilazodone up to 135 and 150 mg/kg/day, respectively, for 2 years. These doses are approximately 16.5 and 36 times the maximum recommended human dose (MRHD) of 40 mg, respectively, on a mg/m² basis.

In mice, the incidence of hepatocellular carcinomas was increased in males at 16.5 times the MRHD; this finding was not observed at 5.5 times the MRHD. The incidence of malignant mammary gland tumors was numerically increased in females at 5.5 and 16.5 times the MRHD, with statistical significance at 16.5 the MRHD; this finding was not observed at 1.8 times the MRHD. Elevated prolactin levels were observed in a 2-week study of vilazodone administered at 5.5 and 33 times the MRHD. Increases in prolactin levels are known to cause mammary tumors in rodents.

In the rat study, vilazodone was not carcinogenic in either sex at doses up to 36 times the MRHD.

Mutagenesis Vilazodone was not mutagenic in the in vitro bacterial reverse mutation assay (Ames test). Vilazodone was negative in the in vitro V79/HGRPT mammalian cell forward mutation assay. Vilazodone was clastogenic in two in vitro mammalian cell chromosome aberration assays. However, vilazodone was negative for clastogenic activity in both an in vivo rat bone marrow chromosome aberration assay and a micronucleus test. Vilazodone was also negative in an in vivo/in vitro unscheduled DNA synthesis assay in rats.

Impairment of Fertility Treatment of rats with vilazodone at a dose of 125 mg/kg, which is 30 times the MRHD of 40 mg on a mg/m² basis, caused impairment of male fertility with no effect on female fertility. Impaired male fertility was not observed at 6 times the MRHD.

14

The efficacy of vilazodone as a treatment for major depressive disorder was demonstrated in four multicenter, randomized, double-blind, placebo-controlled studies in adult (18-70 years of age) outpatients who met the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) criteria for MDD. Three 8-week studies evaluated the efficacy of vilazodone 40 mg (Studies 1-3) and one 10-week study (Study 4) evaluated the efficacy of vilazodone 20 mg and 40 mg (see Table 5). In these studies, patients were randomized to either 20 mg or 40 mg, or placebo once daily with food. Patients were either titrated over 1 week to a dose of 20 mg daily or over 2 weeks to a dose of 40 mg once daily of vilazodone with food. Vilazodone was superior to placebo in the improvement of depressive symptoms as measured by the change from baseline to endpoint visit in the Montgomery-Asberg Depression Rating Scale (MADRS) total score for both doses. The MADRS is a ten-li, clinician-rated scale used to assess severity of depressive symptoms. Scores on the MADRS range from 0 to 60, with higher scores indicating more severe depression. Clinical Global Impression - Severity (CGI-S) was evaluated in Studies 3 and 4. Vilazodone 20 mg and 40 mg demonstrated superiority over placebo as measured by improvement in CGI-S score.

Advise the patient to read the FDA-approved patient labeling (Medication Guide).

Suicid al Thoughts and Behaviors Advise patients and caregivers to look for the emergence of suicidality, especially early during treatment and when the dosage is adjusted up or down and instruct them to report such symptoms to the healthcare provider [ see Boxed Warning and Warnings and Precautions ( 5.1 ) ].

Dos age and Administration Instruct patients to take vilazodone with food and to follow prescribed dosage instructions [see Dosage and Administration ( 2.1 , 2.3 , 2.4 , 2.5 )].

Serotonin Syndrome Caution patients about the risk of serotonin syndrome, particularly with the concomitant use of vilazodone with other serotonergic drugs including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St. John’s Wort, and with drugs that impair metabolism of serotonin (in particular, MAOIs, both those intended to treat psychiatric disorders and also others, such as linezolid). Patients should contact their health care provider or report to the emergency room if they experience signs or symptoms of serotonin syndrome [ see Warnings and Precautions ( 5.2 ) and Drug Interactions ( 7 ) ].

Increased Risk of Bleeding Inform patients about the concomitant use of vilazodone with aspirin, NSAIDs, other antiplatelet drugs, warfarin, or other anticoagulants because the combined use of drugs that interfere with serotonin reuptake (e.g., vilazodone) and these medications has been associated with an increased risk of bleeding. Advise them to inform their health care providers if they are taking or planning to take any prescription or over-the-counter medications that increase the risk of bleeding [ see Warnings and Precautions ( 5.3 ) ].

Activation of Mania/Hypomania Advise patients and their caregivers to observe for signs of activation of mania/hypomania and instruct them to report such symptoms to the healthcare provider [ see Warnings and Precautions ( 5.4 ) ].

Discontinuation Syndrome Advise patients not to abruptly discontinue vilazodone and to discuss any tapering regimen with their healthcare provider. Adverse reactions can occur when vilazodone is discontinued [see Warnings and Precautions ( 5.5 )].

Seizures Caution patients about using vilazodone if they have a history of a seizure disorder [see Warnings and Precautions ( 5.6 )].

Sexual Dysfunction Advise patients that use of vilazodone may cause symptoms of sexual dysfunction in both male and female patients. Inform patients that they should discuss any changes in sexual function and potential management strategies with their healthcare provider [ see

Warnings and Precautions ( 5.9 )].

Allergic Reactions Advise patients to notify their healthcare provider if they develop an allergic reaction such as rash, hives, swelling, or difficulty breathing [see Adverse Reaction s ( 6.2 )].

Concomitant Medications Advise patients to inform their health care providers if they are taking, or plan to take any prescription or over-the-counter medications since there is a potential for interactions [see Drug Interactions ( 7.1 )].

Pregnancy

Advise pregnant women to notify their healthcare provider if they become pregnant or intend to become pregnant during treatment with vilazodone [see Use in Specific Populations ( 8.1 )].

Advise patients that vilazodone use late in pregnancy may lead to an increased risk for neonatal complications requiring prolonged hospitalization, respiratory support, tube feeding, and/or persistent pulmonary hypertension of the newborn (PPHN) [see Use in Specific Populations ( 8.1 )].

Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to vilazodone during pregnancy[see Use in Specific Populations ( 8.1 )].

MEDICATION GUIDE V ilazodone Tablets, for oral use

What is the most important information I should know about Vilazodone ? Vilazodone may cause serious side effects, including:

Increased risk of suicidal thoughts or actions in some children, adolescents, and young adults. Vilazodone and other antidepressant medicines may increase suicidal thoughts or actions in some people 24 years of age and younger, especially within the first few months of treatment or when the dose is changed. v ilazodone is not for use in children. ○ Depression or other serious mental illnesses are the most important causes of suicidal thoughts or actions. Some people may have a higher risk of having suicidal thoughts or actions. These include people who have (or have a family history of) depression, bipolar illness (also called manic-depressive illness) or have a history of suicidal thoughts or actions. How can I watch for and try to prevent suicidal thoughts and actions? ○ Pay close attention to any changes, especially sudden changes in mood, behavior, thoughts, or feelings, or if you develop suicidal thoughts or actions. This is very important when an antidepressant medicine is started or when the dose is changed. ○ Call your healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings. ○ Keep all follow-up visits with your healthcare provider as scheduled. Call your healthcare provider between visits as needed, especially if you have concerns about symptoms. Call your healthcare provider or get emergency medical help right away if you or your family member have any of the following symptoms, especially if they are new, worse, or worry you:

Table 4: Clinically Important Drug Interactions with Vilazodone
Concomitant Drug Name or Drug Class	Clinical Rationale	Clinical Recommendation
Monoamine Oxidase Inhibitors (MAOIs)	The concomitant use of MAOIs and serotonergic drugs including vilazodone increases the risk of serotonin syndrome.	Vilazodone is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Contraindications ( 4 ), Dos age and Administration ( 2.3 ) , and Warnings and Precautions ( 5.2 )].
Other Serotonergic Drugs	The concomitant use of serotonergic drugs including vilazodone and other serotonergic drugs increases the risk of serotonin syndrome.	Monitor patients for signs and symptoms of serotonin syndrome, particularly during vilazodone initiation. If serotonin syndrome occurs, consider discontinuation of vilazodone and/or concomitant serotonergic drugs [see Warnings and Precautions ( 5.2 )].
Antiplatelet Agents and Anticoagulants	Serotonin release by platelets plays an important role in hemostasis. The concurrent use of an antiplatelet agent or anticoagulant with vilazodone may potentiate the risk of bleeding.	Inform patients of the increased risk of bleeding with the concomitant use of vilazodone and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio (INR) when initiating, titrating, or discontinuing vilazodone [see Warnings and Precautions ( 5.3 )].
Strong CYP3A4 Inhibitors (e.g., itraconazole, clarithromycin, voriconazole)	The concomitant use of vilazodone and strong CYP3A4 inhibitors increased the exposure of vilazodone compared to the use of vilazodone alone [see Clinical Pharmacology ( 12.3 )].	The vilazodone dose should not exceed 20 mg once daily with the concomitant use of a strong CYP3A4 inhibitor [see Dosage and Administration ( 2.4 ) , Clinical Pharmacology ( 12.3 ) ] .
Strong CYP3A4 Inducers (e.g., carbamazepine, phenytoin, rifampin)	The concomitant use of vilazodone and strong CYP3A4 inducers decreased the exposure of vilazodone compared to the use of vilazodone alone [see Clinical Pharmacology ( 12.3 )].	Based on clinical response, consider increasing the dosage of vilazodone, over 1 to 2 weeks in patients taking strong CYP3A4 inducers for greater than 14 days [see Dosage and Administration ( 2.4 ) , Clinical Pharmacology ( 12.3 ) ].
Digoxin	Digoxin is a narrow therapeutic index drug. Concomitant use of vilazodone increased digoxin concentrations [see Clinical Pharmacology ( 12.3 )].	Measure serum digoxin concentrations before initiating concomitant use of vilazodone. Continue monitoring and reduce digoxin dose as necessary.
