Key result
Oral nitrendipine lowers mean arterial pressure by ~25% in spontaneously hypertensive rats.
Why the study?
The effects of the slow channel calcium blocker nitrendipine on systemic and regional hemodynamics in normotensive and spontaneously hypertensive rats were not fully characterized.
Does oral nitrendipine reduce blood pressure and alter regional hemodynamics in normotensive and spontaneously hypertensive rats?
Population
Twenty-week-old normotensive Wistar-Kyoto and spontaneously hypertensive conscious male rats
Comparison
Nitrendipine oral administration (1 mg or 10 mg/kg) vs pretreatment levels
Design
Preclinical hemodynamic study using radioactive reference sample and microsphere techniques
Follow-up
1 hour

Supports nitrendipine investigation in hypertensive models; leaves open clinical translation pending human trials.
Does oral nitrendipine reduce blood pressure and alter regional hemodynamics in normotensive and spontaneously hypertensive rats?
Absolute Event Rate: 25% vs 14%
p-value: p=<0.001
Nitrendipine effectively lowers blood pressure in hypertensive rats by reducing peripheral resistance while maintaining blood flow to vital organs.
Sesoko et al. (1984) studied Hypertension. Nitrendipine vs. Normotensive Wistar-Kyoto (WKY) controls was evaluated on Reduction in mean arterial pressure (p=<0.001). Oral nitrendipine reduced mean arterial pressure by 25% in spontaneously hypertensive rats compared to 14% in normotensive controls (p<0.001).
