Bromocriptine is a dopaminergic agonist. It acts as a potent agonist on D2 receptor and partial agonist or antagonist on D1 receptor. Bromocriptine produces a decrease in Dopamine turnover with increase in Dopamine content of the brain and decreases the metabolism of Dopamine. The increase in Dopamine concentration produces effect in Parkinson`s disease.
Since Dopamine is a neurotransmitter in the brain it can produces various motor, behavioural and endocrine effects.
