The objective of this study is to estimate the effect of lersivirine on the pharmacokinetics of R-methadone and S-methadone and to investigate the safety and tolerability of lersivirine when co-administered with methadone. Symptoms of methadone withdrawal will also be assessed.
Allocation: Non-Randomized, Endpoint Classification: Pharmacokinetics Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Transfer from methadone to buprenorphine is problematic for many opioid-dependent patients, with limited documented evidence or practical clinical guidance, particularly for the range of methadone dos...
A synthetic opioid that is used as the hydrochloride. It is an opioid analgesic that is primarily a mu-opioid agonist. It has actions and uses similar to those of MORPHINE. It also has a depressant action on the cough center and may be given to control intractable cough associated with terminal lung cancer. Methadone is also used as part of the treatment of dependence on opioid drugs, although prolonged use of methadone itself may result in dependence.
