Bromocriptine
Bromocriptine is a dopamine agonist medication primarily used to treat conditions related to excessive prolactin hormone secretion, such as hyperprolactinemia, prolactinomas (pituitary tumors), and associated symptoms like menstrual irregularities, infertility, and abnormal breast milk production. It is also used in Parkinson's disease management and for certain types of acromegaly.
A dopamine agonist used to treat hormone-related conditions and Parkinson's disease by reducing prolactin levels and mimicking dopamine effects in the brain.

Hyperprolactinemia, prolactin-secreting pituitary adenomas (prolactinomas), Parkinson's disease, acromegaly, and conditions associated with abnormal prolactin levels such as amenorrhea, infertility, and galactorrhea.
As a dopamine agonist, bromocriptine stimulates dopamine receptors in the brain, mimicking the action of natural dopamine. This inhibits prolactin secretion from the pituitary gland, improves dopamine-related motor functions in Parkinson's disease, and reduces growth hormone in acromegaly.
May cause side effects including nausea, dizziness, headache, and low blood pressure, especially when starting treatment. Should be used with caution in patients with cardiovascular disease, psychiatric disorders, or those taking other medications affecting dopamine. Not recommended during pregnancy unless specifically indicated for certain conditions.
