IPRATROPIUM BROMIDE AND ALBUTEROL SULFATE Dailymed

Rx Only

Description

The active components in Ipratropium Bromide and Albuterol Sulfate Inhalation Solution are albuterol sulfate and ipratropium bromide.

Albuterol sulfate, is a salt of racemic albuterol and a relatively selective β ₂-adrenergic bronchodilator chemically described as α ¹-[( tert-butylamino)methyl]-4-hydroxy- m-xylene-α, α'-diol sulfate (2:1) (salt). It has a molecular weight of 576.7 and the empirical formula is (C ₁₃H ₂₁NO ₃) ₂•H ₂SO ₄. It is a white crystalline powder, soluble in water and slightly soluble in ethanol. The World Health Organization recommended name for albuterol base is salbutamol.



Figure 3.1-1. Chemical structure of albuterol sulfate.

Ipratropium bromide is an anticholinergic bronchodilator chemically described as 8-azoniabicyclo [3.2.1]-octane, 3-(3-hydroxy-1-oxo-2-phenylpropoxy)-8methyl-8-(1-methylethyl)-, bromide, monohydrate ( endo, syn)-, (±)-; a synthetic quaternary ammonium compound, chemically related to atropine. It has a molecular weight of 430.4 and the empirical formula is C ₂₀H ₃₀BrNO ₃•H ₂O. It is a white crystalline substance, freely soluble in water and lower alcohols, and insoluble in lipophilic solvents such as ether, chloroform, and fluorocarbons.



Figure 3.1-2. Chemical structure of ipratropium bromide.

Each 3 mL Sterile Unit-dose Vial contains 0.5 mg of ipratropium bromide (0.017%) and 3 mg Equivalent to 2.5 mg albuterol base albuterol sulfate (0.083%) in an isotonic, sterile, aqueous solution containing sodium chloride and 1 N hydrochloric acid to adjust to pH 4.

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution is a clear, colorless solution. It does not require dilution prior to administration by nebulization. For Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, like all other nebulized treatments, the amount delivered to the lungs will depend on patient factors, the jet nebulizer utilized, and compressor performance. Using the Pari-LC-Plusâ„¢ nebulizer (with face mask or mouthpiece) connected to a PRONEBâ„¢ compressor system, under in vitro conditions, the mean delivered dose from the mouth piece (% nominal dose) was approximately 46% of albuterol and 42% of ipratropium bromide at a mean flow rate of 3.6 L/min. The mean nebulization time was 15 minutes or less. Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should be administered from jet nebulizers at adequate flow rates, via face masks or mouthpieces (see DOSAGE AND ADMINISTRATION).

Clinical Pharmacology

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution is a combination of the β ₂-adrenergic bronchodilator, albuterol sulfate, and the anticholinergic bronchodilator, ipratropium bromide.

Albuterol sulfate

Mechanism of Action

The prime action of β-adrenergic drugs is to stimulate adenyl cyclase, the enzyme that catalyzes the formation of cyclic-3',5'-adenosine monophosphate (cAMP) from adenosine triphosphate (ATP). The cAMP thus formed mediates the cellular responses. In vitro studies and in vivo pharmacologic studies have demonstrated that albuterol has a preferential effect on β ₂-adrenergic receptors compared with isoproterenol. While it is recognized that β ₂-adrenergic receptors are the predominant receptors in bronchial smooth muscle, recent data indicated that 10% to 50% of the β-receptors in the human heart may be β ₂-receptors. The precise function of these receptors, however, is not yet established. Albuterol has been shown in most controlled clinical trials to have more effect on the respiratory tract, in the form of bronchial smooth muscle relaxation, than isoproterenol at comparable doses while producing fewer cardiovascular effects. Controlled clinical studies and other clinical experience have shown that inhaled albuterol, like other β-adrenergic agonist drugs, can produce a significant cardiovascular effect in some patients.

Pharmacokinetics

Albuterol sulfate is longer acting than isoproterenol in most patients by any route of administration, because it is not a substrate for the cellular uptake processes for catecholamine nor for the metabolism of catechol-O-methyl transferase. Instead the drug is conjugatively metabolized to albuterol 4'- O-sulfate.

Animal Pharmacology/Toxicology

Intravenous studies in rats with albuterol sulfate have demonstrated that albuterol crosses the blood-brain barrier and reaches brain concentrations amounting to approximately 5% of plasma concentrations. In structures outside of the blood-brain barrier (pineal and pituitary glands), albuterol concentrations were found to be 100 times those found in whole brain.

Studies in laboratory animals (minipigs, rodents, and dogs) have demonstrated the occurrence of cardiac arrhythmias and sudden death (with histological evidence of myocardial necrosis) when beta-agonists and methyl-xanthines are administered concurrently. The clinical significance of these findings is unknown.

Ipratropium bromide

Mechanism of Action

Ipratropium bromide is an anticholinergic (parasympatholytic) agent, which blocks the muscarinic receptors of acetylcholine, and, based on animal studies, appears to inhibit vagally mediated reflexes by antagonizing the action of acetylcholine, the transmitter agent released from the vagus nerve. Anticholinergics prevent the increases in intracellular concentration of cyclic guanosine monophosphate (cGMP), resulting from the interaction of acetylcholine with the muscarinic receptors of bronchial smooth muscle.

Pharmacokinetics

The bronchodilation following inhalation of ipratropium is primarily a local, site-specific effect, not a systemic one. Much of an inhaled dose is swallowed as shown by fecal excretion studies. Following nebulization of a 1-mg dose to healthy volunteers, a mean of 4% of the dose was excreted unchanged in the urine.

Ipratropium bromide is minimally (0% to 9% in vitro) bound to plasma albumin and α ₁-acid glycoproteins. It is partially metabolized to inactive ester hydrolysis products. Following intravenous administration, approximately one-half is excreted unchanged in the urine. The half-life of elimination is about 1.6 hours after intravenous administration. Ipratropium bromide that reaches the systemic circulation is reportedly removed by the kidneys rapidly at a rate that exceeds the glomerular filtration rate. The pharmacokinetics of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution or ipratropium bromide have not been studied in the elderly and in patients with hepatic or renal insufficiency (see PRECAUTIONS).

Animal Pharmacology/Toxicology

Autoradiographic studies in rats have shown that ipratropium does not penetrate the blood-brain barrier.

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution

Mechanism of Action

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution is expected to maximize the response to treatment in patients with chronic obstructive pulmonary disease (COPD) by reducing bronchospasm through two distinctly different mechanisms: sympathomimetic (albuterol sulfate) and anticholinergic/parasympatholytic (ipratropium bromide). Simultaneous administration of both an anticholinergic and a β2-sympathomimetic is designed to produce greater bronchodilation effects than when either drug is utilized alone at its recommended dosage.

Animal Pharmacology/Toxicology

In 30-day studies in Sprague-Dawley rats and Beagle dogs, subcutaneous doses of up to 205.5 mcg/kg of ipratropium administered with up to 1000 mcg/kg albuterol in rats and 3.16 mcg/kg ipratropium and 15 mcg/kg albuterol in dogs (less than the maximum recommended daily inhalation dose for adults on a mg/m ² basis) did not cause death or potentiation of the cardiotoxicity induced by albuterol administered alone.

Pharmacokinetics

In a double blind, double period, crossover study, 15 male and female subjects were administered single doses of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution or albuterol sulfate inhalation solution at two times the recommended single doses as two inhalations separated by 15 minutes. The total nebulized dose of albuterol sulfate from both treatments was 6 mg and the total dose of ipratropium bromide from Ipratropium Bromide and Albuterol Sulfate Inhalation Solution was 1 mg. Peak albuterol plasma concentrations occurred at 0.8 hours after dosing for both treatments. The mean peak albuterol concentration following administration of albuterol sulfate alone was 4.86 (± 2.65) mg/mL and it was 4.65 (± 2.92) mg/mL for Ipratropium Bromide and Albuterol Sulfate Inhalation Solution. Mean AUC values for the two treatments were 26.6 (± 15.2) ng∙hr/mL (albuterol sulfate alone) versus 24.2 (± 14.5) ng∙hr/mL (Ipratropium Bromide and Albuterol Sulfate Inhalation Solution). The mean t _1/2 values were 7.2 (± 1.3) hours (albuterol sulfate alone) and 6.7 (± 1.7) hours (Ipratropium Bromide and Albuterol Sulfate Inhalation Solution). A mean of 8.4 (± 8.9)% of the albuterol dose was excreted unchanged in urine following administration of two vials of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution which is similar to 8.8 (± 7.3)% that was obtained from albuterol sulfate inhalation solution. There were no statistically significant differences in the pharmacokinetics of albuterol between the two treatments. For ipratropium, a mean of 3.9 (± 5.1)% of the ipratropium bromide dose was excreted unchanged in urine following two vials of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, which is comparable with previously reported data.

Clinical Trials

In a 12 week, randomized, double-blind, positive-control, crossover study of albuterol sulfate, ipratropium bromide, and Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, 863 COPD patients were evaluated for bronchodilator efficacy comparing ipratropium bromide and albuterol sulfate with albuterol sulfate and ipratropium bromide alone.

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution demonstrated significantly better changes in FEV ₁, as measured from baseline to peak response, when compared with either albuterol sulfate or ipratropium bromide. Ipratropium Bromide and Albuterol Sulfate Inhalation Solution was also shown to have the rapid onset associated with albuterol sulfate, with a mean time to peak FEV ₁ of 1.5 hours, and the extended duration associated with ipratropium bromide with a duration of 15% response in FEV ₁ of 4.3 hours.



Figure 3. 1-3. Mean Change in FEV ₁ - Measured on Day 14

This study demonstrated that each component of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution contributed to the improvement in pulmonary function, especially during the first 4 to 5 hours after dosing, and that Ipratropium Bromide and Albuterol Sulfate Inhalation Solution was significantly more effective than albuterol sulfate or ipratropium bromide alone.

Indications And Usage

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution is indicated for the treatment of bronchospasm associated with COPD in patients requiring more than one bronchodilator.

Contraindications

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution is contraindicated in patients with a history of hypersensitivity to any of its components, or to atropine and its derivatives.

Warnings

Paradoxical Bronchospasm

In the clinical study of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, paradoxical bronchospasm was not observed. However, paradoxical bronchospasm has been observed with both inhaled ipratropium bromide and albuterol products and can be life-threatening. If this occurs, Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should be discontinued immediately and alternative therapy instituted.

Do Not Exceed Recommended Dose

Fatalities have been reported in association with excessive use of inhaled products containing sympathomimetic amines and with the home use of nebulizers.

Cardiovascular Effect

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, like other beta adrenergic agonists, can produce a clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms. Although such effects are uncommon for Ipratropium Bromide and Albuterol Sulfate Inhalation Solution at recommended doses, if they occur, the drug may need to be discontinued. In addition, beta agonists have been reported to produce ECG changes, such as flattening of the T-wave, prolongation of the QTc interval, and ST segment depression. The clinical significance of these findings is unknown. Therefore, Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, like other sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.

Immediate Hypersensitivity Reactions

Immediate hypersensitivity reactions to albuterol and/or ipratropium bromide may occur after the administration of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution as demonstrated by rare cases of urticaria, angioedema, rash, pruritus, oropharyngeal edema, bronchospasm, and anaphylaxis.

Precautions

General

1. Effects Seen with Sympathomimetic Drugs

As with all products containing sympathomimetic amines, Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension; in patients with convulsive disorders, hyperthyroidism, or diabetes mellitus; and in patients who are unusually responsive to sympathomimetic amines. Large doses of intravenous albuterol have been reported to aggravate pre-existing diabetes mellitus and ketoacidosis. Additionally, β-agonists may cause a decrease in serum potassium in some patients, possibly through intracellular shunting. The decrease is usually transient, not requiring supplementation.

2. Effects Seen with Anticholinergic Drugs

Due to the presence of ipratropium bromide in Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, it should be used with caution in patients with narrow-angle glaucoma, prostatic hypertrophy, or bladder-neck obstruction.

3. Use in Hepatic or Renal Diseases

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution has not been studied in patients with hepatic or renal insufficiency. It should be used with caution in these patient populations.

Information for Patients

The action of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should last up to 5 hours. Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should not be used more frequently than recommended. Patients should be instructed not to increase the dose or frequency of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution without consulting their healthcare provider. If symptoms worsen, patients should be instructed to seek medical consultation.

Patients must avoid exposing their eyes to this product as temporary pupillary dilation, blurred vision, eye pain, or precipitation or worsening of narrow-angle glaucoma may occur, and therefore proper nebulizer technique should be assured, particularly if a mask is used.

If a patient becomes pregnant or begins nursing while on Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, they should contact their healthcare provider about use of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution.

See the illustrated Patient's Instruction for Use in the product package insert.

Drug Interactions

Anticholinergic agents

Although ipratropium bromide is minimally absorbed into the systemic circulation, there is some potential for an additive interaction with concomitantly used anticholinergic medications. Caution is, therefore, advised in the co-administration of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution with other drugs having anticholinergic properties.

-adrenergic agents

Caution is advised in the co-administration of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution and other sympathomimetic agents due to the increased risk of adverse cardiovascular effects.

-receptor blocking agents

These agents and albuterol sulfate inhibit the effect of each other. β-receptor blocking agents should be used with caution in patients with hyperreactive airways, and if used, relatively selective β ₁ selective agents are recommended.

Diuretics

The electrocardiogram (ECG) changes and/or hypokalemia that may result from the administration of non-potassium sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by β-agonists, especially when the recommended dose of the β-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the co-administration of β-agonist-containing drugs, such as Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, with non-potassium sparing diuretics.

Monoamine oxidase inhibitors or tricyclic antidepressants

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents because the action of albuterol sulfate on the cardiovascular system may be potentiated.

Carcinogenesis, Mutagenesis, Impairment of Fertility

Albuterol Sulfate

In a 2-year study in Sprague-Dawley rats, albuterol sulfate caused a significant dose-related increase in the incidence of benign leiomyomas of the mesovarium at and above dietary doses of 2 mg/kg (approximately equal to the maximum recommended daily inhalation dose for adults on a mg/m ² basis). In another study, this effect was blocked by the coadministration of propranolol, a non-selective beta-adrenergic antagonist.

In an 18-month study in CD-1 mice, albuterol sulfate showed no evidence of tumorigenicity at dietary doses up to 500 mg/kg (approximately 140 times the maximum recommended daily inhalation dose for adults on a mg/m ² basis). In a 22-month study in Golden hamsters, albuterol sulfate showed no evidence of tumorigenicity at dietary doses up to 50 mg/kg (approximately 20 times the maximum recommended daily inhalation dose for adults on a mg/m ² basis).

Albuterol sulfate was not mutagenic in the Ames test or a mutation test in yeast. Albuterol sulfate was not clastogenic in a human peripheral lymphocyte assay or in an AH1 strain mouse micronucleous assay.

Reproduction studies in rats demonstrated no evidence of impaired fertility at oral doses of albuterol sulfate up to 50 mg/kg (approximately 25 times the maximum recommended daily inhalation dose for adults on a mg/m ² basis).

Ipratropium bromide

In 2-year studies in Sprague-Dawley rats and CD-1 mice, ipratropium bromide showed no evidence of tumorigenicity at oral doses up to 6 mg/kg (approximately 15 times and 8 times the maximum recommended daily inhalation dose for adults in rats and mice respectively, on a mg/m ² basis).

Ipratropium bromide was not mutagenic in the Ames test and mouse dominant lethal test. Ipratropium bromide was not clastogenic in a mouse micronucleous assay.

A reproduction study in rats demonstrated decreased conception and increased resorptions when ipratropium bromide was administered orally at a dose of 90 mg/kg (approximately 240 times the maximum recommended daily inhalation dose for adults on a mg/m ² basis). These effects were not seen with a dose of 50 mg/kg (approximately 140 times the maximum recommended daily inhalation dose for adults on a mg/m ² basis).

Pregnancy

TERATOGENIC EFFECTS

Pregnancy Category C

Labor and Delivery

Oral albuterol sulfate has been shown to delay preterm labor in some reports. Because of the potential of albuterol to interfere with uterine contractility, use of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution during labor should be restricted to those patients in whom the benefits clearly outweigh the risks.

Nursing Mothers

It is not known whether the components of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution are excreted in human milk. Although lipid-insoluble quaternary bases pass into breast milk, it is unlikely that ipratropium bromide would reach the infant to an important extent, especially when taken as a nebulized solution. Because of the potential for tumorigenicity shown for albuterol sulfate in some animals, a decision should be made whether to discontinue nursing or discontinue Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, taking into account the importance of the drug to the mother.

Pediatric Use

The safety and effectiveness of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution in patients below 18 years of age have not been established.

Geriatric Use

Of the total number of subjects in clinical studies of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution, 62 percent were 65 and over, while 19 percent were 75 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

Adverse Reactions

Adverse reaction information concerning Ipratropium Bromide and Albuterol Sulfate Inhalation Solution was derived from the 12-week controlled clinical trial.

Additional adverse reactions reported in more than 1% of patients treated with Ipratropium Bromide and Albuterol Sulfate Inhalation Solution included constipation and voice alterations.

In the clinical trial, there was a 0.3% incidence of possible allergic-type reactions, including skin rash, pruritus, and urticaria.

Additional information derived from the published literature on the use of albuterol sulfate and ipratropium bromide singly or in combination includes precipitation or worsening of narrow-angle glaucoma, acute eye pain, blurred vision, mydriasis, paradoxical bronchospasm, wheezing, exacerbation of COPD symptoms, drowsiness, aching, flushing, upper respiratory tract infection, palpitations, taste perversion, elevated heart rate, sinusitis, back pain, sore throat and metabolic acidosis. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Overdosage

The effects of overdosage with Ipratropium Bromide and Albuterol Sulfate Inhalation Solution are expected to be related primarily to albuterol sulfate, since ipratropium bromide is not well-absorbed systemically after oral or aerosol administration. The expected symptoms with overdosage are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of symptoms such as seizures, angina, hypertension or hypotension, tachycardia with rates up to 200 beats per minute, arrhythmia, nervousness, headache, tremor, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, insomnia, and exaggeration of pharmacological effects uled in ADVERSE REACTIONS. Hypokalemia may also occur. As with all sympathomimetic aerosol medications, cardiac arrest and even death may be associated with abuse of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution. Treatment consists of discontinuation of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution together with appropriate symptomatic therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. There is insufficient evidence to determine if dialysis is beneficial for overdosage of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution.

The oral median lethal dose of albuterol sulfate in mice is greater than 2000 mg/kg (approximately 540 times the maximum recommended daily inhalation dose of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution on a mg/m ² basis). The subcutaneous median lethal dose of albuterol sulfate in mature rats and small young rats is approximately 450 and 2000 mg/kg respectively (approximately 240 and 1100 times the maximum recommended daily inhalation dose of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution on a mg/m ² basis, respectively). The inhalation median lethal dose has not been determined in animals. The oral median lethal dose of ipratropium bromide in mice, rats and dogs is greater than 1000 mg/kg, approximately 1700 mg/kg and approximately 400 mg/kg, respectively (approximately 1400, 4600, and 3600 times the maximum recommended daily inhalation dose in adults on a mg/m ² basis, respectively).

Dosage And Administration

The recommended dose of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution is one 3 mL vial administered 4 times per day via nebulization with up to 2 additional 3 mL doses allowed per day, if needed. Safety and efficacy of additional doses or increased frequency of administration of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution beyond these guidelines has not been studied and the safety and efficacy of extra doses of albuterol sulfate or ipratropium bromide in addition to the recommended doses of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution have not been studied.

The use of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution can be continued as medically indicated to control recurring bouts of bronchospasm. If a previously effective regimen fails to provide the usual relief, medical advice should be sought immediately, as this is often a sign of worsening COPD, which would require reassessment of therapy.

A Pari-LC-Plusâ„¢ nebulizer (with face mask or mouthpiece) connected to a PRONEBâ„¢ compressor was used to deliver Ipratropium Bromide and Albuterol Sulfate Inhalation Solution to each patient in one U.S. clinical study. The safety and efficacy of Ipratropium Bromide and Albuterol Sulfate Inhalation Solution delivered by other nebulizers and compressors have not been established.

Ipratropium Bromide and Albuterol Sulfate Inhalation Solution should be administered via jet nebulizer connected to an air compressor with an adequate air flow, equipped with a mouthpiece or suitable face mask.
