Patient w/ parkinsonian syndrome who manifest mild degrees of dementia or w/ history of MI and a residual atrial, nodal or ventricular arrhythmia, pleuropulmonary signs and symptoms, history of psychosis, CV disease, Raynaud’s syndrome, history of peptic ulcer. Renal or hepatic impairment. Childn. Pregnancy.

Very rarely, HTN, MI, seizures or stroke.
Patient Counseling Information
This drug may cause somnolence and/or sudden sleep onset, if affected, do not drive or operate machinery.
Monitoring Parameters
Monitor for pituitary enlargement, visual field to detect secondary field loss in macroprolactinoma fibrotic disease; BP and heart rate (at baseline and periodically), GI bleeding and pregnancy test during amenorrheic period.
Symptoms: Vomiting, nausea, dizziness, hypotension, postural hypotension, tachycardia, drowsiness, somnolence, lethargy, confusion and hallucination. Management: Symptomatic and supportive treatment. Administer activated charcoal; may perform gastric lavage if intake is very recent. May give metoclopramide for emesis or hallucinations.
Drug Interactions
Increased plasma level w/ erythromycin and other macrolide antibiotics. Effects of antihypertensives may be potentiated. Diminished therapeutic effect w/ dopamine antagonists such as psychotropics (e.g. phenothiazines, butyrophenones, thioxanthenes). Additive neurologic effect w/ levodopa. Reduced prolactin-lowering effect w/ metoclopramide and domperidone. Potentially severe adverse effects may occur w/ concomitant use of other ergot alkaloids.
Food Interaction
Food reduces nausea caused by bromocriptine. Alcohol reduces tolerance to bromocriptine.
Mechanism of Action: Bromocriptine is a dopamine D2 agonist which activates postsynaptic dopamine receptors in the tuberoinfundibular pathway that inhibits the secretion of prolactin from the anterior pituitary and may lower blood level of growth hormone. It also stimulates nigrostriatal pathways in the corpus striatum to enhance coordinated motor control.
Absorption: Rapidly absorbed from the GI tract. Bioavailability: Approx 6%. Time to peak plasma concentration: W/in 1-3 hr.
Distribution: Plama protein-binding: 90-96%, mainly albumin.
Metabolism: Undergoes extensive hepatic first-pass metabolism; converted to lysergic acid and peptides via hydrolysis.
Excretion: Via faeces (approx 82%) and urine (approx 2-6%). Elimination half-life: Biphasic: Approx 4-4.5 hr; 15 hr.
