[The effect of the flesinoxan subtype of serotonin C1a receptor agonist on the arterial pressure in rats].

The effect of a high-affinity C1A serotonin receptor agonist flesinoxan on the arterial blood pressure and the heart rate in normotensive Wistar rats, spontaneously hypertensive rats and inherited stress-induced arterial hypertension rats was studied. It was shown that both peripheral and central administration of flesinoxan produces a decrease of blood pressure and heart rate. However, a reduction of heart rate was more pronounced at the drug peripheral administration. The sensitivity to flesinoxan in the hypertensive rats was greater than in the normotensive rats.
