Essential Hypertension
Conditions
Brief summary
This study is designed to evaluate the additional efficacy and safety of olmesartan medoxomil/hydrochlorothiazide in the treatment of Chinese patients with mild to moderate essential hypertension, who fail to attain the blood pressure goals with olmesartan medoxomil monotherapy
Interventions
olmesartan medoxomil 20mg oral tablets, once daily for 4 weeks then olmesartan medoxomil 20mg oral tablets + hydrochlorothiazide 12.5 mg oral tablets, once daily for up to 8 weeks
olmesartan medoxomil 20mg oral tablets, once daily for 4 weeks then olmesartan medoxomil 40mg oral tablets, once daily for up to 8 weeks
