Etravirin ve Hidrokodon ve homatropin etkileşimi

In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in hydrocodone plasma concentration.

Concomitant use with CYP3A4 inhibitors (or discontinuation of CYP3A4 inducers) can result in a fatal overdose of hydrocodone.

Avoid the use of hydrocodone bitartrate and homatropine methylbromide in patients who are taking CYP3A4 inducers.

Similarly, discontinuation of a CYP3A4 inducer, such as rifampin, carbamazepine, and phenytoin, in hydrocodone bitartrate and homatropine methylbromide-treated patients may increase hydrocodone plasma concentrations and prolong opioid adverse reactions.

Concomitant use of hydrocodone bitartrate and homatropine methylbromide with CYP3A4 inducers or discontinuation of a CYP3A4 inhibitor could decrease hydrocodone plasma concentrations, decrease opioid efficacy or, possibly, lead to a withdrawal syndrome in a patient who had developed physical dependence to hydrocodone.

Narcotic analgesics/treatment of opioid dependence: buprenorphine buprenorphine/naloxone methadone ↔ etravirine ↓ buprenorphine ↔ norbuprenorphine ↔ methadone Etravirine and buprenorphine (or buprenorphine/naloxone) can be co-administered without dose adjustments, however, clinical monitoring for withdrawal symptoms is recommended as buprenorphine (or buprenorphine/naloxone)…
