Az 5-aminoszalicilsav- (5-ASA-) készítmények mind a mai napig a colitis ulcerosa terápiájának alapvető gyógyszereit jelentik. Számos orálisan adható 5-ASA-készítmény van forgalomban, beleértve az azo-kötést tartalmazó prodrugokat (például sulfalazin, olsalazin, balzalazid), valamint a mesalazin elnyújtott és kontrollált hatóanyag-kibocsátású kiszereléseit. Az orális terápia hatékonysága a beteg jó együttműködésén is múlik, amelynek gátat szabhat a naponta többször adott, nagyszámú tabletta bevétele. Ez a tényező a colitis ulcerosában szenvedő betegek terápiájának pontos betartásában jelentős akadályt képezhet. A közelmúltban egy új, naponta egyszer adandó, egyedülálló multimátrix mesalazinkészítmény és a szintén naponta egy alkalommal adható mesalazingranulátum hatékonynak bizonyult az enyhe-közepes súlyosságú colitis ulcerosa indukciós és fenntartó terápiájában. A mellékhatásprofil ugyanakkor nem különbözött a hagyományos mesalazinkészítményektől. A ritka adagolás a betegek jobb hosszú távú compliance-e által hozzájárulhat a betegek hatékonyabb kezeléséhez és várhatóan a colitis ulcerosával kapcsolatos colorectalis carcinoma rizikójának csökkentéséhez. A szerzők az alábbi közleményben összefoglalják az új, naponta egyszer adandó mesalazinkészítmények rövid és közepes távú hatékonyságával és biztonságosságával kapcsolatban elérhető irodalmi adatokat.
