Effects of an antihypertensive drug, guanfacine, on brain regional cyclic AMP and cyclic GMP levels were studied in anesthetized rats. Cyclic nucleotides were analyzed in seven brain regions. Guanfacine decreased blood pressure and heart rate 20 min after administration. Yohimbine inhibited these hemodynamic effects of guanfacine. Guanfacine reduced cyclic AMP levels in the hypothalamus. The reducing effect of guanfacine on cyclic AMP was antagonized by yohimbine in the hypothalamus. Guanfacine lowered cyclic GMP in the cerebellum, medulla oblongata and hypothalamus. Yohimbine inhibited the effect of guanfacine on cyclic GMP in the cerebellum, medulla oblongata and hypothalamus. Prazosin showed no effect on guanfacine induced change of cyclic nucleotides in any brain region. From these results, it is concluded that guanfacine decreased cyclic AMP and cyclic GMP in the hypothalamus. In addition, it is suggested that alpha-2 adrenoceptors mainly modulate these changes of cyclic nucleotides.
