Abstract:

The drug Perindopril Erbumine (PE), an ACE inhibitor, and can be used to treat the patients with hypertension and cardiac failure problems. A sensitive, inexpensive, and precise analytical technique has been developed for the estimation of Perindopril in bulk and formulations. The procedure involves the development of color by forming an oxidative coupling reaction between drug (PE) and Brucine/IO4-). The formed colored species were measured at max=520 nm. The developed method showed linearity within the concentration limits of 8-24 μg mL-1. The linear correlation coefficient (r) and molar absorptivity were found to be 0.9999 and 9.16 x 103 mol-1.cm-1. % Recovery ± SD values were in the range of 99.16 - 100.7 (± 0.41 - ± 0.8) (n=3) which indicates the accuracy of the developed method. The interference of other excipients that are commonly present in formulations is found to be negligible. Precision and accuracy of the proposed method were confirmed by Student’s t-test and F-tests at 95% confidence limits with (n-1) degrees of freedom. The validity parameters of the proposed method were calculated by ICH guidelines.
