Aspirin is one of the most widely used drugs in the treatment of inflammation, pain and fever. It has more recently found application in the prevention of heart attacks and stroke and is being studied as a cancer chemopreventative agent. Despite its value aspirin continues to be underutilized because it causes gastric bleeding. The technology under development potentially removes this problem. It is designed to reduce contact between the drug and the intestinal lining. An isosorbide aspirinate prodrug compound is thus provided. The compound has the general structure as shown in general formula (I) wherein Y is a C1 - C8 alkyl ester, a C1 - C8 alkoxy ester, a C3 - C10 cycloalkyl ester, an arylester, a C1 - C8 alkylaryl ester or -C(O)ORring, wherein Rring is a 5-membered aromatic or nonaromatic 5-member ring having at least one heteroatom substituted for a carbon of the ring system, which can be unsubstituted or substituted with at least one nitric oxide releasing group.

Aspirin prodrugs and related nitric oxide releasing compounds hold significant therapeutic promise, but they are hard to design because aspirin esterification renders its acetate group very susceptible to plasma esterase mediated hydrolysis. Isosorbide-2-aspirinate-5-salicylate is a true aspirin prodrug in human blood because it can be effectively hydrolyzed to aspirin upon interaction with plasma
