एट्राविरिन और मैराविरोक का इंटरैक्शन

• If patients with severe renal impairment or ESRD receiving SELZENTRY (without concomitant CYP3A inducers or inhibitors) experience postural hypotension, the dose of SELZENTRY should be reduced from 300 mg twice daily to 150 mg twice daily.

• Coadministration with CYP3A inducers, including efavirenz, may decrease the concentration of SELZENTRY.

The pharmacokinetics of maraviroc are likely to be modulated by inhibitors and inducers of CYP3A and P-gp and may be modulated by inhibitors of OATP1B1 and MRP2.

CCR5 antagonists maraviroc ↔ etravirine ↓ maraviroc When Etravirine is co-administered with maraviroc in the absence of a potent CYP3A inhibitor (e.g., ritonavir boosted protease inhibitor), the recommended dose of maraviroc is 600 mg twice daily.

Stevens-Johnson syndrome was reported in 1.1% (2/177) of pediatric patients less than 18 years of age receiving Etravirine in combination with other HIV-1 antiretroviral agents in an observational study.

No dose adjustment of Etravirine is needed. maraviroc/darunavir/ ritonavir The reference for etravirine exposure is the pharmacokinetic parameters of etravirine in the presence of darunavir/ritonavir. ↔ etravirine ↑ maraviroc When Etravirine is co-administered with maraviroc in the presence of a potent CYP3A inhibitor (e.g., ritonavir boosted protease inhibitor),…
