A Phase III Clinical Study of Cabergoline Tablets Compared With Bromocriptine Mesylate Tablets

A randomized, double-blind, double-dummy, active controlled, multicenter Phase III clinical study to evaluate the efficacy and safety of Cabergoline tablets compared with Bromocriptine mesylate tablets in female patients with hyperprolactinemia

• Cabergoline tablets (Drug): Cabergoline tablets will be administered for 14 weeks.The allowed dose range is from 0.25 mg (1 tablet) QW to 1mg (4 tablets) QW. Dosage adjustments are made based on the serum PRL level.
• Bromocriptine mesylate tablets (Drug): Bromocriptine mesylate tablets was administered for 14 weeks.The dose is 1.25 mg (0.5 tablet) QD to 7.5mg 3 tablets) QD. Dosage adjustments are made based on the serum PRL level.

Primary outcomes

• The percentage of subjects whose serum PRL levels returned to normal [14 weeks]

Secondary outcomes

• The percentage of subjects whose ovulatory cycles resumed [14 weeks]
• The percentage of subjects whose galactorrhea disappeared [14 weeks]
• The percentage of subjects with pituitary PRL tumor shrinkage [14 weeks]

Sex: Female, ages: 18 Years to 45 Years
