in the long-term management of ulcerative colitis patients, repeat dosing maybe required. since 5-asa is largely absorbed from the upper intestine, selective delivery of drugs into the colon may be regarded as a better method of drug delivery with fewer side effects and a higher efficacy. the aim of this study was to prepare and evaluate a double coated multiparticulate system for 5-asa deliver...

5-aminosalicylic acid (5-asa) is currently prepared by electrochemical reduction of 5-nitrosalicylic acid (5-nsa) in acidic media. in this work, electrolytic reduction of 5-nsa in alkaline media is presented. reactionconditions and parameters such as anode and cathode electrodes, electrolyte type, reaction time, temperature,current, and the ph for isolation of product are investigated. the yiel...
