Drug: Asacol HD
Each Asacol HD delayed-release tablet for oral administration contains 800 mg of mesalamine, an antiinflammatory drug. Asacol HD delayed-release tablets have an outer protective coat consisting of a combination of acrylic based resins, Eudragit S (methacrylic acid copolymer B, NF) and Eudragit L (methacrylic acid copolymer A, 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: Molecular Weight : 153.1
Molecular Formula : C7H7NO3 Inactive Ingredients: Each tablet contains colloidal silicon dioxide, dibutyl phthalate, edible black ink, ferric oxide red, ferric oxide yellow, lactose monohydrate, magnesium stearate, methacrylic acid copolymer B (Eudragit S), methacrylic acid copolymer A (Eudragit L), polyethylene glycol, povidone, sodium starch glycolate, and talc.

There is no specific antidote for mesalamine overdose and treatment for suspected acute severe toxicity with Asacol HD (mesalamine delayed-release tablets, oral) should be symptomatic and supportive. This may include prevention of further gastrointestinal tract absorption, correction of fluid electrolyte imbalance, and maintaining adequate renal function. Asacol HD (mesalamine delayed-release tablets, oral) 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 Asacol HD (mesalamine delayed-release tablets, oral) based on body surface area), 4595 mg/kg in rats (approximately 7.8 times the recommended human dose of Asacol HD (mesalamine delayed-release tablets, oral) based on body surface area) and 3000 mg/kg in cynomolgus monkeys (approximately 10 times the recommended human dose of Asacol HD based on body surface area) were lethal.

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 Asacol HD that contain or are converted to mesalamine. It is recommended that all patients have an evaluation of renal function prior to initiation of Asacol HD (mesalamine delayed-release tablets, oral) and periodically while on therapy. Exercise caution when using Asacol HD (mesalamine delayed-release tablets, oral) in patients with known renal dysfunction or history of renal disease. In animal studies (rats, mice, dogs), the kidney was the principal organ for toxicity [see Nonclinical Toxicology]. Exacerbation of Ulcerative Colitis Symptoms Exacerbation of the symptoms of colitis has been reported in 2.3% of Asacol HD (mesalamine delayed-release tablets, oral) -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 Asacol HD tablets as well as other mesalamine products. Symptoms usually abate when Asacol HD (mesalamine delayed-release tablets, oral) tablets are discontinued. Hypersensitivity Some patients who have experienced a hypersensitivity reaction to sulfasalazine may have a similar reaction to Asacol HD tablets or to other compounds that contain or are converted to mesalamine. Pyloric Stenosis Patients with pyloric stenosis may have prolonged gastric retention of Asacol HD tablets, which could delay release of mesalamine in the colon. Use in Hepatic Impairment 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 Asacol HD (mesalamine delayed-release tablets, oral) to patients with liver disease. Nonclinical Toxicology 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 0.8 and 1.7 times the 4.8 g/day Asacol HD 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 0.8 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. Use In Specific Populations Pregnancy Pregnancy Category B: Reproduction studies have been performed in rats at oral doses up to 480 mg/kg/day (about 0.8 times the recommended human treatment dose of 4.8 g/day based on body surface area) and rabbits at oral doses up to 480 mg/kg/day (about 1.6 times the recommended human treatment dose of 4.8 g/day based on body surface area) and have revealed no evidence of impaired fertility or harm to the fetus due to mesalamine. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Mesalamine is known to cross the placental barrier. Nursing Mothers Mesalamine and its N-acetyl metabolite have been detected in human breast milk. The clinical significance of this has not been determined. Caution should be exercised when Asacol HD (mesalamine delayed-release tablets, oral) is administered to a nursing woman. Pediatric Use Safety and effectiveness of Asacol HD (mesalamine delayed-release tablets, oral) in pediatric patients have not been established. Geriatric Use Clinical studies of Asacol HD (mesalamine delayed-release tablets, oral) did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently than younger subjects. Other reported clinical experience has not identified differences in response between the elderly and younger patients. 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 Asacol HD (mesalamine delayed-release tablets, oral) . Reports from uncontrolled clinical studies and postmarketing reporting systems for Asacol (mesalamine) suggested a higher incidence of blood dyscrasias, i.e., agranulocytosis, neutropenia, pancytopenia, in patients who were 65 years or older. Caution should be taken to closely monitor blood cell counts during mesalamine therapy. Mesalamine is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken when prescribing this drug therapy. It is recommended that all patients have an evaluation of renal function prior to initiation of Asacol HD therapy and periodically while on Asacol HD (mesalamine delayed-release tablets, oral) therapy [see WARNINGS AND PRECAUTIONS].
