Bergolak instructions for use

Bergolac is a drug of the dopamine receptor agonist group that suppresses prolactin secretion. It is used to treat disorders developing in hyperprolactinemia.

Release form and composition

Bergolak is available in tablets, 2, 8, 10 and 30 tablets per pack.

The main active ingredient is cabergoline. 1 tablet contains 500 µg of cabergoline.

Auxiliary components: magnesium stearate, lactose anhydrous, leucine.

pharmachologic effect

Pharmacodynamics. Cabergoline reduces the content of prolactin in the blood, helps to restore the menstrual cycle. In women, as a result of a decrease in the concentration of prolactin, the production of gonadotropins and the release of luteinizing hormone are restored. The severity of hyperandrogenic (hirsutism, acne ) and hypoandrogenic (fluid retention, osteoporosis, weight gain) symptoms decreases.

In men, such manifestations of hyperprolactinemia as impotence and decreased libido, lactorrhea, gynecomastia (decrease in the concentration of prolactin causes an increase in testosterone production) are reduced.

Pharmacokinetics. Cabergoline is well absorbed. Absorption rates do not depend on meal times. The time to reach the maximum plasma concentration of the active substance is from half an hour to 4 hours. 41–42% of cabergoline is bound to blood proteins. The half-life in patients with hyperprolactinemia ranges from 79 to 115 hours, in healthy people, this figure varies from 63 to 68 hours. Since the period of removal of cabergoline is long, the equilibrium concentration of the substance in the blood is noted after 4 weeks of treatment.

The drug is metabolized, but the metabolites are characterized by a significantly lower therapeutic effect. Excreted by the kidneys (18%, of which about 3% unchanged) and through the intestines (72%).

For the treatment of hyperprolactinemia and related disorders - 500 µg per week (1 tablet once or ½ tablet in two doses, with an interval of 3-4 days). With a monthly interval, the dose is increased by 500 μg to achieve the expected therapeutic effect. Typically, the optimal therapeutic dose is 1000 mcg per week, but can vary from 250 mcg to 2000 mcg (from ½ tablet to 4 tablets) of cabergoline.
