Figure 1: Chemical structure of verapamil. Verapamil HCl is available as sustainable release caplets with brand names Calan SR (Labelled claim 180 mg.), extended release capsules (Labelled claim 300 mg.) and as injection (Labelled claim 5 mg, 10 mg: 2.5 mg/ml). Verapamil HCl is also available as tablets with label claim 40, 80 and 120 mg (Nicholas Piramal India Ltd). This article summarises the analytical techniques proposed by different authors for the quantification of Verapamil such as spectrophotometry [3-6] (Table 1), HPLC [8-12], UPLC [13], LC-MS/MS [14-16] and LC-MS [17] and table 2 represents some of the significant parameters observed in liquid chromatographic methods. The State Pharmacopoeia of Ukraine [18] has a monograph on the substance of verapamil hydrochloride and on verapamil hydrochloride tablets. To identify the substance of verapamil hydrochloride, State Pharmacopoeia of Ukraine offers UV-spectrophotometry, absorption spectrophotometry in the infrared region, TLC (mobile ...
