This drug may cause somnolence or sudden sleep onset, if affected, do not drive or operate machinery. Women of childbearing potential must use proven birth control methods during therapy and for at least 1 month after stopping the treatment.
Chỉ số theo dõi
Evaluate the pregnancy status in women of childbearing potential before treatment initiation and monthly in case of amenorrhoeic period. Perform echocardiogram (at baseline, within 3-6 months after initiation, every 6-12 months thereafter and as clinically indicated) and chest X-ray (at baseline and as necessary). Obtain ESR and serum creatinine levels at baseline and regularly during treatment. Monitor blood pressure and serum prolactin levels (monthly until normalised). Assess for signs and symptoms of pleuro-pulmonary disease, cardiac failure, renal insufficiency, ureteral or abdominal obstruction, hypotension, amenorrhoea, and mental status changes during therapy.
Quá liều
Symptoms: Nausea, vomiting, nasal congestion, gastric complaints, orthostatic hypotension, confusion, psychosis, or hallucinations. Management: Symptomatic and supportive treatment. Measures should be taken to maintain blood pressure, if necessary. Administration of activated charcoal within 1 hour of ingestion or giving dopamine antagonists may be considered.
Tương tác
Decreased prolactin-lowering effect with dopamine antagonists (e.g. phenothiazines, butyrophenones, thioxanthenes, metoclopramide). Enhanced risk of orthostatic hypotension with antihypertensives. Increased systemic bioavailability with macrolide antibiotics (e.g. erythromycin).
Tác dụng
Description: Mechanism of Action: Cabergoline, an ergot-derivative, is a long-acting dopamine agonist with a high binding affinity for dopamine D2 receptors. It inhibits prolactin secretion from the anterior pituitary gland through direct stimulation of the dopamine D2 receptors on pituitary lactotrophs. Pharmacokinetics: Absorption: Rapidly absorbed from the gastrointestinal tract. Time to peak plasma concentration: 2-3 hours. Distribution: Extensively distributed throughout the body (particularly to the pituitary). Plasma protein binding: 40-42%. Metabolism: Extensively metabolised in the liver via hydrolysis; minimal CYP450-mediated metabolism. Undergoes first-pass metabolism. Excretion: Mainly via faeces (approx 60%); urine (approx 22%; <4% as unchanged drug). Elimination half-life: 63-69 hours.
