Under the requirements of this REMS program, the drug manufacturer must develop educational programs regarding the safe and effective use of opioids for your doctor
Zidovudine – Experimental evidence demonstrated that methadone increased the area under the concentration-time curve (AUC) of zidovudine which could result hinein toxic effects.
In the selection of an initial dose of methadone hydrochloride tablets, attention should be given to the following:
Although antiretroviral drugs such as efavirenz, nelfinavir, nevirapine, ritonavir, lopinavir + ritonavir combination are known to inhibit some CYPs, they are shown to reduce the plasma levels of methadone, possibly due to their CYP induction activity. Therefore, drugs administered concomitantly with methadone should be evaluated for interaction potential; clinicians are advised to evaluate individual response to drug therapy before making a dosage adjustment.

Coadministration of methadone with inducers of these enzymes may result rein more rapid methadone metabolism, and potentially, decreased effects of methadone. Conversely, administration with CYP inhibitors may reduce metabolism and potentiate methadone's effects. Pharmacokinetics of methadone may Beryllium unpredictable when coadministered with drugs that are known to both induce and inhibit CYP enzymes.
