Bromitine mesilate is a nonhormonal, nonestrogenic agent that inhibits the secretion of prolactin in humans, with little or no effect on other pituitary hormones, except in patients with acromegaly, where it lowers elevated blood levels of growth hormone. Bromitine mesilate is a dopamine receptor agonist, which activates post-synaptic dopamine receptors.The dopaminergic neurons in the tuberoinfundibular process modulate the secretion of prolactin from the anterior pituitary by secreting a prolactin inhibitory factor (thought to be dopamine); in the corpus striatum the dopaminergic neurons are involved in the control of motor function. Clinically, it significantly reduces plasma levels of prolactin in patients with physiologically elevated prolactin as well as in patients with hyperprolactinemia.
Hyperprolactinemia-Associated Dysfunctions: Dysfunctions associated with hyperprolactinemia including amenorrhea with or without galactorrhea, infertility or hypogonadism. Prolactin-secreting adenomasdn cases where adenectomy is elected, a course of bromocriptine mesilate therapy may be used to reduce the tumor mass prior to surgery.
Acromegaly Parkinson's Disease: Idiopathic or postencephalitic Parkinson's disease- As adjunctive treatment to levodopa (alone or with a peripheral decarboxylase inhibitor)
Bromitine is also used to associated treatment for these conditions: Acromegaly, Parkinson's Disease (PD), Type 2 Diabetes Mellitus, Idiopathic hyperprolactinemic disorder, Neuroleptic malignant syndrome (NMS)

Side effects in decreasing order of frequency are: nausea, headache, dizziness,fatigue, lightheadedness,vomiting .abdominal cramps,nasal congestion,constipation,diarrhea and drowsiness. A slight hypotensive effect may accompany treatment.The occurrence of adverse reactions may be lessened by temporarily reducing dosage to 0.5 mg. Abnormalities in laboratory tests may include elevations in blood urea nitrogen, SGOT, SGPT, GGPT, CPK, alkaline phosphatase and uric acid, which are usually transient and not of clinical significance.
Bromitine may interact with dopamine antagonists, butyrophenones, and certain other agents. Compounds in these categories result in a decreased efficacy of Bromitine: phenothi-azines, haloperidol, metodopramide, pimozide. Concomitant use of Bromitine with other ergot alkaloids is not recommended.
- Avoid alcohol.
- Take with food. Food reduces irritation.
