Abbreviated New Drug Application
MESALAMINE- MESALAMINE PADAGIS ISRAEL PHARMACEUTICALS LTD ---------- MESALAMINE RECTAL SUSPENSION, USP ENEMA 4g/unit (60 mL) RX ONLY DESCRIPTION The active ingredient in Mesalamine Rectal Suspension, USP Enema, a disposable (60 mL) unit, is mesalamine, also known as 5-aminosalicylic acid (5-ASA). Chemically, mesalamine is 5-amino-2-hydroxybenzoic acid. The empirical formula is C H NO , representing a molecular weight of 153.14. The structural formula is: Each rectal suspension enema unit contains 4 grams of mesalamine. In addition to mesalamine the preparation contains the inactive ingredients carbomer 934P, edetate disodium, potassium acetate, potassium metabisulfite, purified water and xanthan gum. Sodium benzoate is added as a preservative. The disposable unit consists of an applicator tip protected by a polyethylene cover and lubricated with USP white petrolatum. The unit has a one-way valve to prevent back flow of the dispensed product. CLINICAL PHARMACOLOGY Each mesalamine rectal suspension enema delivers up to 4 g of mesalamine to the left side of the colon. The mechanism of action of mesalamine (and sulfasalazine) is not fully understood, but appears to be a topical anti-inflammatory effect on colonic epithelial cells. Mucosal production of arachidonic acid (AA) metabolites, both through the cyclooxygenase pathways, i.e., prostanoids, and through the lipoxygenase pathways, i.e., leukotrienes (LTs) and hydroxyeicosatetraenoic acids (HETEs) is increased in patients with ulcerative colitis, and it is possible that mesalamine diminishes inflammation by blocking cyclooxygenase and inhibiting prostaglandin (PG) production in the colon. PRECLINICAL TOXICOLOGY - 7 7 3 Preclinical studies have shown the kidney to be the major target organ for mesalamine toxicity. Adverse renal function changes were observed in rats after a single 600 mg/kg oral dose, but not after a 200 mg/kg dose. Gross kidney lesions, including papillary necrosis, were observed after a single oral >900 mg/kg dose, and after I.V. doses of > 214 m Baca dokumen lengkap
