Reducing GI Side Effects of NSAIDS by Mutual Prodrug Approach

Prodrug has been the concept of retro metabolic drug design that incorporates targeting, metabolism and duration of action consideration into the design process. The carboxylic groups of NSAIDs can be temporarily masked and its direct effect on gastric mucosa can be minimized. Ester prodrugs of has been synthesized using various carrier moieties as reduce their GIT irritation and improve bioavailability. Prodrugs of several NSAIDs, such as diclofenac, Aspirin, ketoprofen etc have been synthesized using 1, 4-dihydro-1-methylpyridine-3-carboxylate as a carrier to brain to treat Alzheimer's disease. Our aim is to reduce the gastric irritation due to direct contact of the drugs with the gastric mucosa and increased absorption using mutual prodrug approach.
