The active ingredient in Bromocriptine, bromocriptine mesylate, acts by stimulating dopamine D2 receptors, which has multiple physiological effects. For patients with Parkinson’s disease, this stimulation helps counter the dopamine deficiency typically seen in the disease, leading to improvement in symptoms such as rigidity, tremors, and bradykinesia. In conditions related to high levels of prolactin (like prolactinomas and certain fertility issues), Bromocriptine’s effect on dopamine receptors leads to decreased secretion of prolactin from the pituitary gland, often resulting in normalization of prolactin levels, shrinkage of prolactinoma tumors, and restoration of fertility in some cases.

Bromocriptine is a medication that plays a significant role in the management of several health conditions, including Parkinson’s disease, prolactinoma (prolactin-secreting tumors), type 2 diabetes, and certain conditions caused by high levels of the hormone prolactin. It belongs to a class of drugs known as dopamine receptor agonists, which work by activating dopamine receptors in the brain. This activation can decrease the production of prolactin in cases of prolactinoma and improve motor control in Parkinson’s disease by simulating the action of dopamine. Bromocriptine is available in oral forms, such as tablets and capsules, and should be taken as prescribed by a healthcare professional.
