NNRTIs include rilpivirine (Edurant[R]), etravirine (Intelence[R]), delavirdine (Rescriptor[R]), efavirenz (Sustiva[R]), and nevirapine (Viramune[R]) (AIDSinfo, 2016; FDA, 2016).
[19] Nevirapine, delavirdine and efavirenz, abacavir, amprenavir cause rashes frequently due to hypersensitivity which usually resolve spontaneously.
They include delavirdine (Rescriptor), efavirenz (Sustiva, Stocrin), nevirapine (Viramune) and etravirine (Intelence).
In addition, patients received delavirdine with or without adefovir.
In this study, one primary NNRTI mutation (Y181C) was observed (Y181C mutation causes high-level resistance to nevirapine and delavirdine and low-level resistance to efavirenz), while no primary NRTI mutation was noted.
Mutations associated with minor resistance to protease inhibitors (L10I) and non-nucleoside reverse transcription inhibitors (E138A) were detected in sequences from patient TV919, and a mutation conferring high-level resistance to delavirdine (P236L) was detected in patient TV725.
Two types of ARV drugs--nonnucleoside reverse transcriptase inhibitors (NNRTIs), including delavirdine, nevirapine and efavirenz, and protease inhibitors (PIs), such as ritonavir, nelfinavir, lopinavir, saquinavir, and indinavir--are all susceptible to increased liver metabolism as a result of alcohol-mediated induction of the CYP3A4 enzyme system.
