studies of the inhibition of [ 3h ] -dihydroergocryptine binding by the selective alpha 1-adrenoceptor antagonist prazosin or the selective alpha 2-adrenoceptor antagonist rauwolscine revealed the alpha-adrenoceptor population to consist of approximately 25 % alpha 1-adrenoceptors and 75 % alpha 2-adrenoceptors .
