Study of Nalbuphine ER in Participants With Hepatic Impairment
brief summary
This research study will evaluate the effect of hepatic impairment on the pharmacokinetics (the breakdown of the drug in the body) of parallel-group, multiple oral doses nalbuphine extended release (NAL ER), tablets in people with hepatic impairment (mild, moderate and severe), compared to people with normal liver function. The study will also test the safety and tolerability of the NAL ER, when it is given to participants with mild, moderate and severe hepatic impairment, compared to participants with normal liver function. This protocol will also study the effects of this drug on itching in hepatic impairment participants if they report some itching prior to taking part in this study.
