What it is used to treat
INDICATIONS AND USAGE Cabergoline Tablets, USP are indicated for the treatment of hyperprolactinemic disorders, either idiopathic or due to pituitary adenomas.
About this medicine
DESCRIPTION Cabergoline Tablets, USP contain cabergoline USP, a dopamine receptor agonist. The chemical name for cabergoline USP is 1-[(6-allylergolin-8ß-yl)-carbonyl]-1-[3-(dimethylamino)propyl]-3-ethylurea. Its molecular formula is C 26 H 37 N 5 O 2 , and its molecular weight is 451.62. The structural formula is as follows: Cabergoline USP is a white powder soluble in ethyl alcohol, chloroform, and N, N-dimethylformamide (DMF); slightly soluble in 0.1N hydrochloric acid; very slightly soluble in n-hexane; and insoluble in water. Each tablet, for oral administration, contains 0.5 mg of cabergoline USP. Inactive ingredients consist of citric acid, croscarmellose sodium, magnesium stearate and microcrystalline cellulose.

Who should not take it
CONTRAINDICATIONS Cabergoline Tablets, USP are contraindicated in patients with Uncontrolled hypertension or known hypersensitivity to ergot derivatives. History of cardiac valvular disorders, as suggested by anatomical evidence of valvulopathy of any valve, determined by pre-treatment evaluation including echocardiographic demonstration of valve leaflet thickening, valve restriction, or mixed valve restriction-stenosis (See WARNINGS ). History of pulmonary, pericardial, or retroperitoneal fibrotic disorders (See WARNINGS ).
Warnings
WARNINGS 1. Pregnancy: Dopamine agonists in general should not be used in patients with pregnancy-induced hypertension, for example, preeclampsia, eclampsia, and postpartum hypertension, unless the potential benefit is judged to outweigh the possible risk. 2. Fibrotic Complications: a. Cardiac Valvulopathy: All patients should undergo a cardiovascular evaluation, including echocardiogram to assess the potential presence of valvular disease. If valvular disease is detected, the patient should not be treated with Cabergoline (See CONTRAINDICATIONS ) . Post-marketing cases of cardiac valvulopathy have been reported in patients receiving Cabergoline. These cases have generally occurred during administration of high doses of Cabergoline (>2mg/day) used for the treatment of Parkinson’s disease. Cases of cardiac valvulopathy have also been reported in patients receiving lower doses for the treatment of hyperprolactinemic disorders. A multi-country, retrospective cohort study using general practice records and record linkage systems in the UK, Italy and the Netherlands was conducted to assess the association between new use of dopamine agonists including cabergoline (n=27,812) for Parkinson’s disease and hyperprolactinemia and cardiac valvular regurgitation (CVR), other fibroses, and other cardiopulmonary events over a maximum of 12 years of follow up. In this study, the use of cabergoline among persons with Parkinson’s disease was associated with an increased risk of CVR when compared to non-ergot-derived dopamine agonists (Das) and levodopa [Incidence Rate (IR) per 10,000 person years of 68.1 (95% confidence interval (CI): 37.2 to 115.3) for cabergoline vs. 10.0 (95% CI: 5.2 to 19.4) for non-ergot Das and 11.3 (95% CI: 7.2 to 17.0) for levodopa]. In the study analysis confined to persons with dopamine agonist-treated hyperprolactinemia (n=8,386), when compared to non-use (n=15,147), persons exposed to cabergoline did not have an elevated risk of CVR.

Reported side effects
ADVERSE REACTIONS The safety of Cabergoline Tablets has been evaluated in more than 900 patients with hyperprolactinemic disorders. Most adverse events were mild or moderate in severity. In a 4-week, double-blind, placebo-controlled study, treatment consisted of placebo or cabergoline at fixed doses of 0.125, 0.5, 0.75, or 1 mg twice weekly. Doses were halved during the first week. Since a possible dose-related effect was observed for nausea only, the four cabergoline treatment groups have been combined. The incidence of the most common adverse events during the placebo-controlled study is presented in the following table.

The most common reasons for discontinuation from cabergoline were headache, nausea and vomiting (3, 2, and 2 patients, respectively); the most common reasons for discontinuation from bromocriptine were nausea, vomiting, headache, and dizziness or vertigo (10, 3, 3, and 3 patients, respectively). The incidence of the most common adverse events during the double-blind portion of the comparative trial with bromocriptine is presented in the following table. […]
