Stabilized pharmaceutical solid composition of ACE inhibitor comprising an ACE inhibitor and a selective dosage formulation thereof comprising of meglumine. The ACE inhibitor selectively combined with a dosage form including essentially the meglumine is surprisingly found to avoid the degradation of ACE inhibitor by such dosage forms especially the commonly used pharmaceutical excepients. In particular, the presence of the meglumine in the dosage form for the active along with the active ACE inhibitor surprisingly avoid the degradation of the ACE inhibitor due to a) cyclization via internal nucleophilic attack to form substituted diketopiperazines, b) hydrolysis of the side chain ester group, and c) oxidation to form products having often unwanted coloration. |
