Summary
α-Adrenoceptor antagonists (α-blockers) prevent the actions of sympathomimetic agents on α-adrenoceptors. Certain α-blockers (phentolamine, phenoxybenzamine) are non-specific and inhibit both α1- and α2-receptors, whereas others selectively inhibit α1-receptors (prazosin) or α2-receptors (yohimbine). The actions of specific α-adrenoceptor stimulation are shown in Table 14.1.
