5 Warnings And Precautions
- Â Renal Impairment: Evaluate the risks and benefits in patients with known renal impairment or taking nephrotoxic drugs; monitor renal function (
5.1 ,7.1 ,8.6 ,13.2 )- Â Mesalamine-induced Acute Intolerance Syndrome: Symptoms may be difficult to distinguish from an ulcerative colitis exacerbation; monitor for worsening symptoms; discontinue if acute intolerance syndrome suspected (
5.2 )- Â Hypersensitivity Reactions, including Myocarditis and Pericarditis: Evaluate patients immediately and discontinue if a hypersensitivity reaction is suspected (
5.3 )- Â Hepatic Failure: Evaluate the risks and benefits in patients with known liver impairment (
5.4 )5.1 Renal Impairment
Renal impairment, including minimal change nephropathy, acute and chronic interstitial nephritis, and, rarely, renal failure, has been reported in patients taking products such as Mesalamine delayed-release tablets that contain or are converted to mesalamine [see Adverse Reactions (6.2)].
Evaluate renal function prior to initiation of Mesalamine delayed-release tablets and periodically while on therapy. Evaluate the risks and benefits of using Mesalamine delayed-release tablets in patients with known renal impairment or history of renal disease or taking concomitant nephrotoxic drugs [see Drug Interactions (7.1), Use in Specific Populations (8.6) and Nonclinical Toxicology (13.2)].
5.2 Mesalamine-Induced Acute Intolerance Syndrome
Mesalamine has been associated with an acute intolerance syndrome that may be difficult to distinguish from an exacerbation of ulcerative colitis. Exacerbation of the symptoms of colitis has been reported in 2.3% of Mesalamine delayed-release tablets-treated patients in controlled clinical trials. This acute reaction, characterized by cramping, abdominal pain, bloody diarrhea, and occasionally by fever, headache, malaise, pruritus, rash, and conjunctivitis, has been reported after the initiation of Mesalamine delayed-release tablets as well as other mesalamine products. Symptoms usually abate when Mesalamine delayed-release tablets are discontinued.
5.3 Hypersensitivity Reactions
Hypersensitivity reactions have been reported in patients taking sulfasalazine. Some patients may have a similar reaction to Mesalamine delayed-release tablets or to other compounds that contain or are converted to mesalamine.
As with sulfasalazine, mesalamine-induced hypersensitivity reactions may present as internal organ involvement, including myocarditis, pericarditis, nephritis, hepatitis, pneumonitis, and hematologic abnormalities. Evaluate patients immediately if signs or symptoms of a hypersensitivity reaction are present. Discontinue Mesalamine delayed-release if an alternative etiology for the signs or symptoms cannot be established.
5.4 Hepatic Failure
There have been reports of hepatic failure in patients with pre-existing liver disease who have been administered mesalamine. Caution should be exercised when administering Mesalamine delayed-release tablets to patients with liver impairment.
6 Adverse Reactions
The most common adverse reactions (≥2%) are headache, nausea, nasopharyngitis, abdominal pain, and worsening of ulcerative colitis (6.1 )

The most serious adverse reactions seen in Mesalamine delayed-release tablets clinical trials or with other products that contain mesalamine or are metabolized to mesalamine were:
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Mesalamine delayed-release tablets has been evaluated in 896 patients with ulcerative colitis in controlled studies. Three six- week, active-controlled studies were conducted comparing Mesalamine delayed-release tablets 4.8 grams per day with mesalamine-delayed release tablets 2.4 grams per day in patients with mildly to moderately active ulcerative colitis. In these studies, 727 patients were dosed with Mesalamine delayed-release tablets and 732 patients were dosed with mesalamine delayed-release tablets.
The most common reactions reported in the Mesalamine delayed-release tablets group were headache (4.7%), nausea (2.8%), nasopharyngitis (2.5%), abdominal pain (2.3%), diarrhea (1.7%), and dyspepsia (1.7%); Table 1 enumerates adverse reactions that occurred in the three studies. The most common reactions in patients with moderately active ulcerative colitis (602 patients dosed with Mesalamine delayed-release tablets and 618 patients dosed with mesalamine delayed-release 400 mg) were the same as all treated patients.
Discontinuations due to adverse reactions occurred in 3.9% of patients in the Mesalamine delayed-release tablets group and in 4.2% of patients in the mesalamine delayed-release tablet comparator group. The most common cause for discontinuation was gastrointestinal symptoms
associated with ulcerative colitis.
Serious adverse reactions occurred in 0.8% of patients in the Mesalamine delayed-release tablets group and in 1.8% of patients in the mesalamine delayed-release tablet comparator group. The majority involved the gastrointestinal system.

7 Drug Interactions
- Nephrotoxic Agents including NSAIDs: Increased risk of nephrotoxicity; monitor for changes in renal function and mesalamine-related adverse reactions. (
7.1 )- Azathioprine or 6-Mercaptopurine: Increased risk of blood disorders; monitor complete blood cell counts and platelet counts (
7.2 )7.1 Nephrotoxic Agents, Including Non-Steroidal Anti-Inflammatory Drugs
The concurrent use of mesalamine with known nephrotoxic agents, including nonsteroidal anti- inflammatory drugs (NSAIDs) may increase the risk of nephrotoxicity. Monitor patients taking nephrotoxic drugs for changes in renal function and mesalamine-related adverse reactions [seeWarnings and Precautions (5.1)].
7.2 Azathioprine or 6-Mercaptopurine
The concurrent use of mesalamine with azathioprine or 6-mercaptopurine may increase the risk for blood disorders. If concomitant use of Mesalamine delayed-release tablets and azathioprineor 6-mercaptopurine cannot be avoided, monitor blood tests, including complete blood cell counts and platelet counts.
8 Use In Specific Populations
Geriatric Patients: Increased risk of blood dyscrasias; monitor complete blood cell counts and platelet counts (8.5 )
8.1 Pregnancy
Risk Summary
Limited published data on mesalamine use in pregnant women are insufficient to inform a drug-associated risk. No fetal harm was observed in animal reproduction studies of mesalamine in rats and rabbits at oral doses approximately 0.97 times (rat) and 1.95 times (rabbit) the recommended human dose [see Data].
The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data
Animal Data
Reproduction studies with mesalamine were performed during organogenesis in rats and rabbits at oral doses up to 480 mg/kg/day. There was no evidence of harm to the fetus. These mesalamine doses were about 0.97 times (rat) and 1.95 times (rabbit) the recommended human dose of 4.8 grams per day, based on body surface area.
8.2 Lactation
Risk Summary
Mesalamine and its N-acetyl metabolite are present in human milk in undetectable to small amounts [see Data]. There are limited reports of diarrhea in breastfed infants. There is no information on the effects of the drug on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Mesalamine delayed-release tablets and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition.
Clinical Considerations
Monitor breastfed infants for diarrhea.
Data
Human Data
In published lactation studies, maternal mesalamine doses from various oral and rectal formulations and products ranged from 500 mg to 3 g daily. The concentration of mesalamine in milk ranged from non-detectable to 0.11 mg/L. The concentration of the N-acetyl-5-aminosalicylic acid metabolite ranged from 5 to 18.1 mg/L. Based on these concentrations, estimated infant daily dosages for an exclusively breastfed infant are 0 to 0.017 mg/kg/day of mesalamine and 0.75 to 2.72 mg/kg/day of N-acetyl-5-aminosalicylic acid.
8.4 Pediatric Use
Safety and effectiveness of Mesalamine delayed-release tablets in pediatric patients have not been established. See the prescribing information for other approved mesalamine products for the safety and effectiveness of these products in pediatric patients.
8.5 Geriatric Use
Clinical studies of Mesalamine delayed-release tablets did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently than younger patients. Reports from uncontrolled clinical studies and postmarketing experience for another oral formulation of mesalamine suggest a higher incidence of blood dyscrasias (agranulocytosis, neutropenia, pancytopenia) in patients who were 65 years or older compared to younger patients. Monitor complete blood cell counts and platelet counts in elderly patients during therapy with
Mesalamine delayed-release tablets.
In general, the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy in elderly patients should be considered when prescribing Mesalamine delayed-release tablets [see Use in Specific Populations (8.6)].
8.6 Renal Impairment
Mesalamine is known to be substantially excreted by the kidney, and the risk of adverse reactions may be greater in patients with impaired renal function. Evaluate renal function in all patients prior to initiation and periodically while on Mesalamine delayed-release tablets therapy. Monitor patients with known renal impairment or history of renal disease or taking nephrotoxic drugs for decreased renal function and mesalamine-related adverse reactions [see Warnings and Precautions (5.1), Drug Interactions (7.1) and Adverse Reactions (6.2)].
10 Overdosage
There is no specific antidote for mesalamine overdose and treatment for suspected acute severe toxicity with Mesalamine delayed-release tablets should be symptomatic and supportive. This may include prevention of further gastrointestinal tract absorption, correction of fluid electrolyte imbalance, and maintenance of adequate renal function. Mesalamine delayed-release tablets is a pH dependent delayed-release product and this factor should be considered when treating a suspected overdose.
Single oral doses of 5000 mg/kg mesalamine suspension in mice (approximately 4.2 times the recommended human dose of Mesalamine delayed-release tablets based on body surface area), 4595 mg/kg in rats (approximately 7.8 times the recommended human dose of Mesalamine delayed-release tablets based on body surface area) and 3000 mg/kg in cynomolgus monkeys (approximately 10 times the recommended human dose of Mesalamine delayed-release tablets based on body surface area) were lethal.
11 Description
Each Mesalamine delayed-release tablet for oral administration contains 800 mg of mesalamine, an aminosalicylate. Mesalamine delayed-release tablets have an outer protective coat consisting of a combination of acrylic based resins, Eudragit S (methacrylic acid and methyl methacrylate copolymer (1:2), NF) and Eudragit L (methacrylic acid and methyl methacrylate copolymer (1:1), NF). The inner coat consists of an acrylic based resin, Eudragit S, which dissolves at pH 7
or greater, releasing mesalamine in the terminal ileum and beyond for topical anti- inflammatory action in the colon. Mesalamine (also referred to as 5-aminosalicylic acid or 5-ASA) has the chemical name 5-amino-2-hydroxybenzoic acid; its structural formula is:
Inactive Ingredients: Each tablet contains colloidal silicon dioxide, dibutyl sebacate, edible black ink, ferric oxide red, ferric oxide yellow, lactose monohydrate, magnesium stearate, methacrylic acid and methyl methacrylate copolymer (1:2) (Eudragit S), methacrylic acid and methyl methacrylate copolymer (1:1) (Eudragit L), polyethylene glycol, povidone, sodium starch glycolate, and talc.
12 Clinical Pharmacology
12.1 Mechanism of Action
The mechanism of action of mesalamine is unknown, but appears to be topical rather than systemic. Mucosal production of arachidonic acid metabolites, both through the cyclooxygenase pathways, that is, prostanoids, and through the lipoxygenase pathways, that is, leukotrienes and hydroxyeicosatetraenoic acids, is increased in patients with chronic inflammatory bowel disease, and it is possible that mesalamine diminishes inflammation by blocking cyclooxygenase and inhibiting prostaglandin production in the colon.
12.3 Pharmacokinetics
Absorption
Plasma concentrations of mesalamine (5-aminosalicylic acid; 5-ASA) and its metabolite, N-acetyl-5- aminosalicylic acid (N-Ac-5-ASA) are highly variable following administration of Mesalamine delayed-release tablets. Following single dose oral administration of Mesalamine delayed-release 800 mg tablet in healthy subjects (N = 139) under fasted conditions, the mean Cmax, AUC8-48h and AUC0-tldc values were 208 ng/mL, 2296 ng.h/mL, and 2533 ng.h/mL, respectively. The median [range] Tmax for mesalamine following administration of Mesalamine delayed-release 800 mg tablet was approximately 24 hours [4 to 72 hours], reflecting the delayed-release characteristics of the formulation.
Based on cumulative urinary recovery of mesalamine and N-Ac-5-ASA from single dose studies in healthy subjects, approximately 20% of the orally administered mesalamine in Mesalamine delayed-release tablets is systemically absorbed.
Food Effect: A high calorie (800 to 1000 calories), high fat (approximately 50 % of total caloric content) meal increased mesalamine Cmax by 2.4-fold and mesalamine systemic exposure (AUC8-48 and AUC0-tldc) by 2.8-fold; the median lag-time increased by 8 hours and median tmax by 6 hours (from 24 to 30 hours) [see Dosage and Administration (2.1)].
Comparative exposure between one Mesalamine delayed-release 800 mg tablet and two mesalamine delayed-release 400 mg oral products is unknown [see Dosage and Administration (2.1)].
Elimination
Metabolism
The absorbed mesalamine is acetylated in the gut mucosal wall and by the liver to N-Ac-5-ASA.
Excretion
Absorbed mesalamine is excreted mainly by the kidneys asN-acetyl-5-aminosalicylic acid. Unabsorbed mesalamine is excreted in feces.
13 Nonclinical Toxicology
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Dietary mesalamine was not carcinogenic in rats at doses as high as 480 mg/kg/day, or in mice at 2000 mg/kg/day. These doses are approximately 0.97 and 2.0 times the 4.8 grams per day Mesalamine delayed-release tablet dose (based on body surface area). Mesalamine was not genotoxic in the Ames test, the Chinese hamster ovary cell chromosomal aberration assay, and the mouse micronucleus test. Mesalamine, at oral doses up to 480 mg/kg/day (about 0.97 times the recommended human treatment dose based on body surface area), was found to have no effect on fertility or reproductive performance of male and female rats.
13.2 Animal Toxicology and/or Pharmacology
In animal studies (rats, mice, dogs), the kidney was the principal organ for toxicity. (In the following, comparisons of animal dosing to recommended human dosing are based on body surface area and a 4.8 grams per day dose for a 60 kg person.)
Mesalamine causes renal papillary necrosis in rats at single doses of approximately 750 mg/kg to 1000 mg/kg (1.5 to 2.0 times the recommended human dose). Doses of 170 and 360 mg/kg/day (about 0.3 and 0.73 times the recommended human dose) given to rats for six months produced papillary necrosis, papillary edema, tubular degeneration, tubular mineralization, and urothelial hyperplasia.
In mice, oral doses of 4000 mg/kg/day (approximately 4.1 times the recommended human dose) for three months produced tubular nephrosis, multifocal/diffuse tubulo-interstitial inflammation, and multifocal/diffuse papillary necrosis.
In dogs, single doses of 6000 mg (approximately 6.25 times the recommended human dose) of delayed- release mesalamine tablets resulted in renal papillary necrosis but were not fatal. Renal changes have occurred in dogs given chronic administration of mesalamine at doses of 80 mg/kg/day (0.5 times the recommended human dose).
14 Clinical Studies
14.1 Moderately Active Ulcerative Colitis
The efficacy of Mesalamine delayed-release tablets at 4.8 grams per day was studied in a six-week, randomized, double-blind, active-controlled study in 772 patients with moderately active ulcerative colitis (UC). Moderately active UC was defined as a Physician's Global Assessment
(PGA) score of 2; the PGA is a four-point scale (0 to 3) that encompasses the clinical assessments of rectal bleeding, stool frequency, and sigmoidoscopy findings.
Patients were randomized 1:1 to the Mesalamine delayed-release tablets 4.8 grams per day group (two Mesalamine delayed-release tablets three times a day) or the mesalamine delayed-release 2.4 grams per day group (two mesalamine delayed-release 400 mg tablets three times a day).
Patients characteristically had a history of previous use of oral 5-ASAs (86%), steroids (41%), and rectal therapies (49%), and demonstrated clinical symptoms of three or more stools over normal per day (87%) and obvious blood in the stool most or all of the time (70%). The study
population was primarily Caucasian (97%), had a mean age of 43 years (8% aged 65 years or older), and included slightly more males (56%) than females (44%).
The primary endpoint was treatment success defined as improvement from baseline to Week 6 based on the PGA. Treatment success rates were similar in the two groups: 70% in the Mesalamine delayed-release tablets group and 66% in the Asacol group (difference: 5%; 95% CI: [-1.9%, 11.2%]).
A second controlled study supported the efficacy of Mesalamine delayed-release tablets at 4.8 grams per day. Treatment success was 72% in patients with moderately active UC treated with Mesalamine delayed-release tablets.
