In this study, a simple and sensitive spectrophotometric method was developed for determination of Losartan potassium (LST K), an angiotensin-II receptor (type AT1) antagonist, in presence of cationic surfactant cetyltrimethylammonium bromide (CTAB). The physicochemical interaction of LST K with CTAB was investigated. The effect of cationic micelles on the(More)

The effect of micelles on the spectral(More)
Three lisinopril-selective electrodes were developed with different techniques and in different polymeric matrices. Precipitation based technique with bathophenanthroline-ferrous as cationic exchanger in polyvinyl chloride (PVC) was used for the fabrication of sensor I (classical electrode) and sensor II (coated wire electrode). Hydroxypropyl ß(More)
A simple, rapid, and sensitive method of reversed-phase high-performance liquid chromatography with fluorescence detection has been developed and validated for use in determining levels of nebivolol•HCl in human plasma. Sample preparation involves a simple single-step protein precipitation procedure and extraction of nebivolol in acetonitrile. The(More)
