Key result
Renin inhibitor A-64662 lowers mean BP by only ~4 mm Hg, underperforming captopril.

Renin inhibitor showed limited BP effect versus captopril in one case; leaves open mechanistic differences beyond angiotensin II suppression.
Case Report (n=1)
No
In a patient with essential hypertension, ACE inhibition with captopril produced a substantially greater blood pressure reduction than direct renin inhibition, suggesting mechanisms beyond circulating angiotensin II reduction.
A 1992 study conducted a case report in essential hypertension (n=1). renin inhibitor A-64662 and captopril was evaluated on blood pressure. Intravenous renin inhibitor A-64662 produced a maximal decrease in mean blood pressure of 4 mm Hg, whereas subsequent administration of captopril resulted in a 17 mm Hg maximal drop.
