Olmesartan Medoxomil and Hydrochlorothiazide is a combination of an Angiotensin II receptor antagonist (Olmesartan Medoxomil) Thiazide diuretic (Hydrochlorothiazide) used in the treatment of mild to moderate essential hypertension in patients who requires combination therapy. The purpose of this study was to evaluate the bioequivalence between Olmesartan Medoxomil/Hydrochlorothiazide 40 mg/12.5 mg Coated Tablets of Abbott and Olmetec Plus^® (Olmesarten Medoxomil/Hydrochlorothiazide) 40 mg/12.5 mg Coated Tablets of Daiichi- Sankyo in healthy, adult, human subjects. An open label, balanced, randomized two treatments, two sequences, two periods, crossover, single dose study with washout period of 02 days under fasting condition was carried out in 28 subjects in the age group of 21 to 44 years and 27 subjects completed the study. All the subjects included in the study were males and asians. The pharmacokinetic samples collected from subjects who completed the study were analysed to determine the plasma concentration of Olmesartan and Hydrochlorothiazide using a validated bioanalytical method. Hydrochlorothiazide is 90% confidence interval of the relative mean C_max, AUC_0-t and AUC_0-∞ of Hydrochlorothiazide were 90.15%-101.65%, 94.67%-105.86%, 94.53%-105.73% respectively, which were within the acceptable limits of 80.00 to 125.00%. Olmesartan is the 90% confidence interval of C_max, AUC_0-t and AUC_0-∞ for Olmesartan was 96.45%-111.65%, 95.33%-108.79% and 95.35%-108.36% respectively, which were within the acceptable limits of 80.00% to 125.00%.
