Summary

A rapid and accurate reversed-phase ion-pairing liquid chromatographic method with UV detection was developed for the simultaneous assay of the angiotensin-converting enzyme inhibitors benazepril hydrochloride, fosinopril sodium and ramipril, and the diuretic hydrochorothiazide.

The separation was achieved on a LC-8 (125×4.0 mml.D.; 5μm particle size) column.

The mobile phase consisted of 20 mM sodium heptanesulphonate (pH=2.5) and methanol (32:68v/v).

Validation of the method showed it to be precise, accurate and linear over the concentration range of analysis with a limit of detection of 1 ng for hydrochorothiazide, 2 ng for ramipril and benazepril and 8 ng for fosinopril.

The method developed was applied to the analysis of three different binary commercial formulations.
