Abstract

The effect of chlorethylclonidine on α₁-adrenoceptor subtypes and arterial blood pressure has been evaluated. Chlorethylclonidine significantly reduced the α₁-adrenoceptor population. Chlorethylclonidine treatment had no significant effect on resting systematic arterial blood pressure or heart rate and shifted the phenylephrine pressor dose-response curve only 2.4-fold to the right. These data suggest that only one of the α₁-adrenoceptor subtypes plays a major role in the regulation of arterial blood pressure.
