Lactation-inhibiting and prolactin-lowering effect of lisuride and bromocriptine: a comparative study.

The prolactin-lowering and lactation-inhibiting effects of lisuride and bromocriptine, two dopaminergic drugs, were compared in a double-blind study. Twenty-six women took lisuride, 0.2 mg b.i.d., and 24 women took bromocriptine, 2.5 mg b.i.d., during 14 days postpartum. Though both drugs gave satisfactory inhibition of puerperal milk production, in these dosages bromocriptine was a more effective lactation inhibitor and prolactin suppressor. After discontinuation of treatment rebound symptoms were more pronounced in the bromocriptine group than in the lisuride group.
