A simple, precise, accurate, selective, and sensitive reversed-phase LC–UV method has been developed for simultaneous analysis of diltiazem and non-steroidal anti-inflammatory drugs (NSAIDs) in the bulk drug, tablet dosage forms, and human serum. Chromatographic separation of the drugs was performed at ambient temperature on a C18 stationary phase with 80:20 (v/v) methanol–water, pH 3.1 ± 0.02, as...
Rapid liquid chromatographic procedures for analytical quality control of pharmaceutical preparations and human serum containing antihistamine drugs, meclizine and buclizine alone or in combination with pyridoxine are proposed, using acetonitrile:water (80:20) as a mobile phase (pH adjusted to 2.6), methylparaben as internal standard and UV detection was made at 230 nm. The results obtained showed...
