Cabergoline tablets are indicated for the treatment of hyperprolactinemic disorders, either idiopathic or due to pituitary adenomas, specifically:
■ Lactation suppression
■ Adjunctive therapy of prolactin-producing pituitary gland tumors (prolactinomas);
■ Monotherapy of Parkinson’s disease in the early phase;
■ Combination therapy, together with levodopa and a decarboxylase inhibitor such as carbidopa, in progressive-phase Parkinson’s disease;
■ In some cases also: ablactation and dysfunctions associated with hyperprolactinemia (amenorrhea, oligomenorrhea, anovulation, nonpuerperal mastitis and galactorrhea);
■ Treatment of uterine fibroids.
■ Adjunctive therapy of acromegaly, cabergoline has low efficacy in suppressing growth hormone levels and is highly efficient in suppressing hyperprolactinemia that is present in 20-30% of acromegaly cases.
The recommended dosage of Cabergoline tablets for initiation of therapy is 0.25 mg twice a week. Dosage may be increased by 0.25 mg twice weekly up to a dosage of 1 mg twice a week according to the patient’s serum prolactin level.
Before initiating treatment, cardiovascular evaluation should be performed and echocardiography should be considered to assess for valvular disease.
Dosage increases should not occur more rapidly than every 4 weeks, so that the physician can assess the patient’s response to each dosage level. If the patient does not respond adequately, and no additional benefit is observed with higher doses, the lowest dose that achieved maximal response should be used and other therapeutic approaches considered.
Patients receiving long term treatment with Cabergoline should undergo periodic assessment of their cardiac status and echocardiography should be considered.
After a normal serum prolactin level has been maintained for 6 months, Cabergoline may be discontinued, with periodic monitoring of the serum prolactin level to determine whether or when treatment with Cabergoline should be reinstituted. The durability of efficacy beyond 24 months of therapy with Cabergoline has not been established.
