This study is open to healthy adults and adults with liver cirrhosis. The purpose of this study is to compare how different medicines are handled by the body in people with and without liver cirrhosis. The study measures if the approved medicines caffeine, warfarin,omeprazole, metoprolol, and midazolam are processed differently in people with liver cirrhosis than in people without liver cirrhosis. This study will help to understand how new medicines being developed are handled by the body in people with liver cirrhosis. There are 3 groups in this study: people without liver cirrhosis, people with mild liver cirrhosis, and people with moderate liver cirrhosis. All participants get 1 dose each of caffeine, warfarin, omeprazole, metoprolol, and midazolam by mouth. The participants with liver cirrhosis continue their regular treatment for the condition during the study. Participants are in the study for about 1 month. During this time, they visit the study site 5 times. For 1 of the visits, participants stay overnight for 2 nights at the study site. To assess the main study endpoint, the doctors take frequent blood samples from the participants. The doctors also regularly check participants' health and take note of any unwanted effects.
