Study to Confirm the Efficacy and Safety of Fixed-dose Combinations of Amlodipine and Candesartan (MACH)

15 oktober 2018 bijgewerkt door: HK inno.N Corporation

A Randomized, Double-blind, Multi-center, Phase Ⅳ Clinical Trial to Evaluate the Antihypertensive Efficacy and Safety Between Amlodipine Besylate/Candesartan Cilexetil Combination Tablets and Co-administration of Amlodipine Besylate and Candesartan Cilexetil in Patients With Essential Hypertension

To evaluate the efficacy and safety of amlodipine besylate and candesartan cilexetil administered in a fixed-dose combination tablet versus co-administered as their separate formulations in patients with essential hypertension who have shown inadequate response on monotherapy of amlodipine or candesartan cilexetil or who are with blood pressure adequately controlled by co-administration of amlodipine besylate and candesartan cilexetil single agents
