Captopril, a specific oral inhibitor of angiotensin-converting enzyme, was given to 18 unselected patients with moderate essential hypertension. Mean blood pressure fell by 14.5% at the maximum dose given, and this fall was significantly correlated with the initial plasma renin activity. The main fall in blood pressure occurred two hours after the first dose of captopril. These results suggest that captopril effectively lowers blood pressure in patients with essential hypertension and that the renin-angiotensin aldosterone system may maintain blood pressure in essential hypertension. This does not necessarily imply that the renin-angiotensin system is the cause of the high blood pressure.
卡托普利是一种特异性口服血管紧张素转换酶抑制剂,给予18例未经挑选的中度原发性高血压患者。在给予最大剂量时,平均血压下降了14.5%,且这种下降与初始血浆肾素活性显著相关。血压的主要下降发生在首次服用卡托普利两小时后。这些结果表明,卡托普利能有效降低原发性高血压患者的血压,且肾素-血管紧张素-醛固酮系统可能维持原发性高血压患者的血压。但这并不一定意味着肾素-血管紧张素系统是高血压的病因。
