thus , the response resistant to alpha-adrenoceptor antagonists could be mediated , in part , by adrenoceptors distinct from alpha-adrenoceptors , as currently defined . alpha , beta-methylene atp reduced the nerve-mediated pressor response after alpha-adrenoceptor blockade or reserpine pretreatment but not in drug-free controls .
