Prescribing-label excerpts

Mesalamine

Reference for: Mesalamine. Source presentation: tablet, delayed release. Source route: oral.

Mechanism of action

The mechanism of action of mesalamine is not fully understood, but appears to be a topical anti-inflammatory effect on colonic epithelial cells. 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 ulcerative colitis, and it is possible that mesalamine diminishes inflammation by blocking cyclooxygenase and inhibiting prostaglandin production in the colon.

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 tablet 800 mg 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 tablet 800 mg 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 tablet 800 mg and two mesalamine delayed-release 400 mg oral products is unknown [see Dosage and Administration (2.1)].

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 as N-acetyl-5-aminosalicylic acid. Unabsorbed mesalamine is excreted in feces.

The studies concern the source product and populations named in each passage; they do not establish Walter-product bioequivalence, an approved indication, or the kinetics of another fixed combination.

Common questions

Before you request a quotation.

Mesalamine 1.2 gm (DR) Tablets

What is listed in the catalogue?

The catalogue lists Mesalamine 1.2 gm (DR) as tablets in its gastroenterology & hepatology navigation area and non-beta-lactam manufacturing stream.

How do you confirm manufacturing availability?

Send Walter your requirement for Mesalamine 1.2 gm (DR) Tablets. The team reviews the applicable product permission and unit, formulation and equipment fit, testing, packaging and production schedule before confirming the manufacturing scope in writing. Request the relevant product and facility documents with your enquiry.

What do I need for a quotation?

Share the exact composition and strength, tablets presentation, target market, initial quantity, preferred pack and timing. Identify whether this is a new product, development brief or transfer.

The quotation must confirm MOQ, inclusions, prerequisites and lead time for the proposed product and site.

What is needed for Indian and export markets?

For India, share the intended brand or institutional supply requirement, pack sizes, initial order quantity and artwork needs for Mesalamine 1.2 gm (DR) Tablets. Confirm the applicable product permission, manufacturing unit and labelling requirements with the team.

For export, identify each destination country, proposed pack, language and registration or dossier requirements. Ask which product-specific quality and stability documents are available.
