Development and Validation of High-Performance Thin-Layer Chromatography Method for Determination of Nebivolol and Amlodipine besylate in Combined Dosage Forms

Abstract

The manuscript describes validated High-Performance Thin-Layer Chromatography (HPTLC) method for the estimation of Nebivolol (NEB) and Amlodipine (AML) in combined dosage form. The HPTLC separation was achieved on an aluminium-backed layer of silica gel 60F254 using chloroform-methanol-toluene-ammonia (8+ 1.8+ 1+ 0.3, v/v/v/v/) as mobile phase. Quantitation was achieved with UV detection at 273 nm over the concentration range 400-1000 ng/spot and 200 – 800 ng/spot for Nebivolol and Amlodipine, respectively with mean recovery of 100.3 ± 0.76 and 100.5 ± 0.92 % for Nebivolol and Amlodipine by HPTLC method. These method were found to be Simple, sensitive, accurate, precise, reproducible, and economical can be applicable for the simultaneous determination of Nebivolol and Amlodipine in combined dosage form.
