Ridogrel is a dual acting thromboxane synthase inhibitor/TP receptor antagonist. We examined the effects of single and multiple doses on systolic blood pressure in stroke-prone spontaneously hypertensive rats. Single doses of ridogrel (5 to 125 mg/kg) did not affect systolic blood pressure or furosemide-stimulated excretion rates of thromboxane B<SUB>2</SUB> or 6-keto-prostaglandin F<SUB>1α</SUB>, although ex vivo serum thromboxane B<SUB>2</SUB> was dose-dependently reduced up to 95%. In contrast, repeated dosing (7 days) with ridogrel (3 to 25 mg/kg/day), had an antihypertensive effect in 12-week-old stroke-prone spontaneously hypertensive rats. At 25 mg/kg/day, ridogrel reduced systolic blood pressure from 200±6.1 to 173±6.7 mmHg (n=12, P
