Abstract: A simple, rapid and precise HPTLC method was developed for the quantitative estimation of terazosin hydrochloride in pharmaceutical dosage form. Good sharp peak was obtained in mobile phase composition Chloroform:Toluene:MeOH (9:1:6) at Rf ≈ 8. Stationary phase was silica gel precoated aluminum plate 60F-254 plates, [20cm × 10cm with 250μm thickness and wavelength selected was 254nm. Terazosin was exposed to acidic, alkaline, thermal, photolytic and oxidative stress conditions, and the stressed samples were analyzed by the proposed method. The described method showed linearity over a range of 50-2500μg/ml. The correlation coefficient is 0.999. Overall, the proposed method was found to be suitable and accurate for quantitative determination and stability study of terazosin in pharmaceutical dosage form.
