drug withdrawal


The aim of this study is to investigate whether inhibition of serum prolactin levels below normal range during cabergoline administration may reduce the recurrence rate after drug withdrawal in patients with prolactinomas.


Prolactinoma patients will be assigned to a experimental group that maintains serum prolactin levels below 5 ng/mL and a control group that maintains normal serum prolactin levels. After that, cabergoline will be maintained at a therapeutic dose for 130 weeks. After cabergoline is discontinued, patients will be followed up with serum prolactin measurement for 52 weeks.
