Taming photo-induced oxidation degradation of dihydropyridine drugs through cocrystallization

Chem Commun (Camb). 2017 Nov 14;53(91):12266-12269. doi: 10.1039/c7cc06992h.

Abstract

Cocrystallization of nifedipine (NFD) and isonicotinamide (INA) resulted in two monotropic cocrystal polymorphs. The thermodynamically more stable polymorph presents superior photostability compared to the other. Cocrystallization can be an efficient approach to address the stability deficit of dihydropyridine drugs.
