pubmed:abstractText |
Injections of phenylephrine into isolated perfused guinea pig hearts increased cyclic AMP and phosphorylase a. Reserpine pretreatment or propranolol decreased or abolished the phenylephrine-induced biochemical changes without affecting the contractile response. Phentolamine, on the other hand, shifted the phenylephrine dose-response curve for contractility to the right without affecting the other parameters. The biochemical effects of phenylephrine are apparently due to the release of noradrenaline while the contractile effect is mediated directly through stimulation of alpha-adrenoceptors.
