Key result
Intravenous administration of benidipine (3 mg/kg and 10 mg/kg) significantly suppressed vasopressin-induced S-wave depression (p<0.01) without causing significant hypotension, demonstrating potent antianginal effects.
Why the study?
Does benidipine improve vasopressin-induced myocardial ischemia with fewer hypotensive effects compared to other calcium-channel blockers in a rat model of angina?

p-value: p=<0.01
Benidipine effectively inhibits coronary vasospasm without causing significant hypotension in a rat model, suggesting a favorable safety profile for angina treatment.

May support benidipine evaluation in human angina trials; leaves open translation from this rat model.
Ikeda et al. (2006) studied Experimental angina (vasopressin-induced myocardial ischemia) (n=88). Benidipine vs. Vehicle, amlodipine, nifedipine, and efonidipine was evaluated on Maximum changes in vasopressin-induced S-wave depression in the electrocardiogram (p=<0.01). Intravenous administration of benidipine (3 mg/kg and 10 mg/kg) significantly suppressed vasopressin-induced S-wave depression (p<0.01) without causing significant hypotension, demonstrating potent antianginal effects.
