Seven dihydropyridine calcium blockers have been analyzed by GC. Simultaneous analysis has been performed both by an isothermal and a gradient method. Moreover, the proposed methods have been performed on the analysis of daylight exposed methanolic solutions of considered compounds; the ability of the systems in separate original compounds from daylight degradation products has been studied. The GC MS spectra of photodegradation products are discussed.
