iN-VITRO INTERACTION STUDIES OF VERAPAMIL WITH FLUOROQUINOLONES USING FIRST ORDER DERIVATIVE UV SPECTROPHOTOMETRY AND RP-HPLC

摘要

Verapamil, a calcium channel blocker, is classified as a class IV anti-arrhythmic agent. It is used in the treatment of hypertension, as an important therapeutic agent for angina pectoris, ischemic heart disease, hypertension and hypertrophic cardiomyopathy. Many in-vivo studies have been carried out to find out the effects on concurrent use of calcium channel blocker with various groups of drugs. In the present paper an in-vitro approach was adapted to study the interaction of verapamil with commonly administered fluoroquinolones i.e. ciprofloxacin, levofloxacin, norfloxacin and sparfloxacin.
