RESULTS AND DISCUSSION: Ultraviolet spectroscopy of Verapamil hydrochloride at λmax of 278 nm in pH 1.2 buffer was found to be linear in range of 20 – 80 µg/ ml. The method was validated and found to be precise‚ specific and accurate. The tablets of Verapamil hydrochloride were prepared by press coating technique showing sustained release for 24 h for once daily dosing with a lag phase of 4 - 6 h. The optimum ratios and type of polymers and other excipients were chosen to produce gastroretentive
