The effectiveness, safety, and tolerability of CV 205-502 in hyperprolactinemic women: a 12-month study

Abstract

Forty-one hyperprolactinemic women (prolactin [PRL] greater than 2,000 mU/L) were treated between 12 and 52 weeks with the new nonergot, long-acting dopamine agonist octahydrobenzo [g] quinoline (CV 205-502). The treatment resulted in normalization of PRL secretion in 71% of the women at a once-daily dose of less than or equal to 0.100 mg. All women responded with a significant decrease in serum PRL. Menstrual function normalized in all women except 1, whereas galactorrhea disappeared in all but 2 patients. During the observation period, four pregnancies were recorded with an additional three in the immediate posttreatment period. Until now, four healthy children have been born. Regarding tolerability, women with fair or poor response bromocriptine (Parlodel) in the past tolerated CV 205-502 better. Two women with no PRL decrease while on Parlodel responded with a decrease while on CV 205-502. All safety parameters remained normal while on treatment, and no significant changes were observed in blood pressure (supine and standing), pulse rate, or electrocardiogram (ECG) recordings. CV 205-502 therefore seems to be a valuable new compound in the management of patients with hyperprolactinemia.
