Abstract

The electrochemical behaviour of nifedipine (I), nitrendipine(II) and their photodegradation products has been studied by employing electrochemical techniques tit chloroform and in 1:4 mixture of chloroform-isopropanol using piperidinium perchlorate (PPC) as supporting electrolyte. It has been shown that I and II undergo in a 4e, 4H(+) irreversible reduction reaction, while the reduction product, phenylhydroxylamine, is oxidized in a 2e, 2H(+) reversible process to an unstable nitrosophenyl compound. Photodegradation of I and II by sunlight produces a nitrosophenyl derivative which is reversibly reduced to the corresponding unstable phenyl-hydroxylamine. No significant change is observed in electrochemical properties of drugs by passing from chloroform to chloroform-isopropanol mixture. The possibility of analysis of I and II by dp polarography is also verified.
