APRISO vs SFROWASA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mesalamine, the active ingredient, is a 5-aminosalicylic acid (5-ASA) that acts locally in the colon to reduce inflammation by inhibiting prostaglandin and leukotriene synthesis, scavenging free radicals, and activating peroxisome proliferator-activated receptor-gamma (PPAR-γ).
SFROWASA is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
1.5 g (3 capsules) orally once daily in the morning. Each capsule contains 0.5 g mesalamine.
5-aminosalicylic acid (mesalamine) 1 g orally 4 times daily for acute treatment; maintenance 500 mg orally 3 times daily.

8.6 ± 4.2 hours for mesalamine; after multiple dosing, effective half-life ~12 hours. Clinical context: allows twice-daily dosing.
Terminal elimination half-life: 12-14 hours in healthy adults; prolonged in hepatic impairment (up to 24 hours) or severe renal disease (up to 20 hours).
Renal (primarily as acetylated metabolite, ~80%) and fecal (~20%).
Renal: 80% as unchanged drug; biliary/fecal: <15% as metabolites; minor hepatic metabolism via CYP3A4.
