The object of this invention was to probe the reactivity of lovastatin, simvastatin, pravastatin, and mevastatin in the solid-state without radical initiators in order to determine the antioxidant that provided the best stability for the statin. Phenolic antioxidants were evaluated.

simvastatin in ethylene dichloride solution with an azo-type free-radical initiator was investigated in kinetic studies using HPLC. The primary products were oligomers, with peroxide groups within the backbone chain, and some monomeric epoxides. These and several secondary products were isolated chromatographically and identified spectroscopically. A reaction scheme was proposed in which the oligomers arise from
