RESUMO
Background & objectives: The aim of this study was to compare the effects of bromocriptine versus cabergoline on pregnancy in hyperprolactinaemic infertile women. Methods: A total of 183 infertile women with hyperprolactinemia undergoing intrauterine insemination (IUI) were randomly divided into two groups. Group A: 94 with bromocriptine and group B:89 with cabergoline. The efficacy and safety was evaluated on the basis of normalization of prolactin levels, normalization of menstrual cycle, disappearance of galactorrhea, occurrence of pregnancy and adverse effects with each of these medications. Results: The presence of galactorrhea and irregular menstruation were significantly lower in patients of group B than group A (P<0.001 and P=0.011, respectively) with a significant lower prevalence of side effects in cabergoline group. Pregnancy was significantly more achieved among the women with the treatment of cabergoline (82%) as compared to bromocriptine (56.4%) (P<0.001). Interpretation & conclusions: Our results suggest that cabergoline treatment in infertile women with prolactinemia is more effective. It lowers prolactin with better tolerability and much more effective in the achievement of pregnancy.
