Mergocriptine (2-methyl-a-ergocryptine or CBM36-733) is a synthetic long-acting ergot derivative. It exerts agonistic action at dopamine receptors. Mergocryptine may induce the suppression of striatal dopamine turnover by reducing dopamine release via the stimulation of presynaptic dopaminergic autoreceptors. In animal experiments, it may affect cerebral hemodynamics. Mergocriptine has a protective effect on the brain against ischemia.
