Synthesis of a novel PEGylated colon-specific azo-based 4- aminosalicylic acid prodrug
Objective(s): 4-aminosalicylic acid (4-ASA) is an isomer of mesalazine that has recently been shown to be effective against inflammatory bowel disease (IBD), and more specifically, ulcerative colitis. However, the majority of orally administered 4-ASA is readily and extensively absorbed from the stomach and small intestine, so only a small amount is transported to the ...
متن کاملRole of 5-aminosalicylic acid (5-ASA) in treatment of inflammatory bowel disease: a systematic review.
Authors' objectives To perform a systematic review of the efficacy of 5-aminosalicylic acid (5-ASA) compounds (oral and topical) in the treatment of inflammatory bowel disease (IBD), both ulcerative colitis (UC) and Crohn's disease (CD), in the acute phase for inducing remission and for the prevention of relapses or recurrences. Also, to evaluate the influence of several factors (such as dosage...
متن کاملNeonatal Presentation of Unremitting Inflammatory Bowel Disease
Very-early-onset inflammatory bowel disease (VEO-IBD) has a distinct phenotype and should be considered a specific entity. VEO-IBD presents with very severe clinical pictures and is frequently known by an indeterminate colitis whose clinical remission is unmanageable. This study examines the case of a neonate with VEO-IBD, not responding to medical and surgical treatment. A 7-day-old Iranian fe...
متن کاملThe value of 5-aminosalicylic acid in inflammatory bowel disease for patients intolerant or allergic to sulphasalazine.
The use of sulphasalazine in inflammatory bowel disease is often limited by intolerance or allergy. In previous studies 5-aminosalicylic acid (5ASA), the active ingredient of sulphasalazine, coated with an acrylic resin, has been shown to be as effective as sulphasalazine in maintaining remission. In this study coated 5ASA was given to 37 patients intolerant or allergic to sulphasalazine. Thirt...
متن کاملEster Prodrug of 5-Aminosalicylic Acid for Colon Specific Drug Delivery: Synthesis, Kinetics, Hydrolysis and Stabilities
Acrylic type polymeric systems having degradable ester bonds linked to the 5-aminosalicylic acid (5-ASA), were synthesized and evaluated for colon targeted drug delivery. The obtained prodrug was characterized by FTIR,HNMR,Melting point and Rf value.In vitro drug release study was conducted at pH 1.2,7.4 and in rat fecal matter. Drug release in rat fecal matter at pH 7.4 was found to be most sa...
