Introduction
Pentasa® tablets encapsulate ethyl‑cellulose microgranules inside a robust shell, releasing mesalamine throughout the GI tract for up to 12 hours. The 500 mg strength offers flexible titration: 2 g BID (4 tabs) for induction, 1 g BID for maintenance. Indian specialists favour tablets for travel (no sachet mess) and child dosing (breakable score line).
