study of ulipristal acetate in female patients with moderately or severely impaired renal function, compared with matched healthy female subjects

Conditions: Renal Function

Summary: this study is designed to observe the effect of renal function on the pharmacokinetic, safety, and tolerability profiles of ulipristal acetate following administration of a single oral dose of a 10 mg ulipristal acetate tablet.
