An interesting development from dopaminergic agents is the search for drugs for the treatment of premenstrual syndrome because pituitary prolactine release is under tonic hypothalamic inhibition by dopamine. Besides, the dopaminergic system plays an important role in physiopathology of migraine, and a dopamine antagonist such as prochlorperazine has exhibited antimigraine properties in animals by possible central amplification of cholinergic transmission. There is therefore a need for original dopaminergic agents, and one of the possible more exciting sources for such agents is the medicinal flora of Asia and the Pacific. The evidence available so far suggests that such agents would be present in the following medicinal plants.
