Introduction

Efavirenz, a synthetic antiretroviral agent, is a non- nucleoside reverse transcriptase inhibitor. While Efavirenz is pharmacologically related to other non nucleoside reverse transcriptase inhibitors, Efavirenz differs structurally from these drugs and also differs structurally from other currently available anti-retroviral agents.

Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI) with activity against HIV-1. It blocks the RNA- and DNA-dependent polymerase activities including HIV-1 replication.

Adiva Precaution

Patient with history of seizures and psychiatric disorders; acute porphyria. Patients receiving voriconazole or rifampicin (weighing ≥50 kg). Discontinue if severe rash or fever develops. Moderate hepatic and severe renal impairment. Childn. Pregnancy.

Interaction

Additive CNS effects w/ psychoactive drugs. May alter plasma warfarin concentrations. May reduce plasma concentrations of HIV integrase inhibitors (e.g. dolutegravir), other HIV NNRTIs (e.g. etravirine), HMG-CoA reductase inhibitors (e.g. simvastatin). Plasma concentrations of efavirenz is increased and that of voriconazole is reduced when given concomitantly. Reduced plasma concentrations w/ rifampicin.

Pregnancy Lactation use

Category D: There is positive evidence of human fetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).

Lactation: Efavirenz may pass through breast milk and cause serious harm to the baby. It should not be used during lactation.

Contraindication

Hypersensitivity. Severe hepatic impairment. Lactation. Concomitant admin with terfenadine, astemizole, cisapride, midazolam, triazolam, pimozide, bepridil, ergot alkaloids, St John’s wort.

Special Warning

Paediatric use:  Efavirenz has not been studied in pediatric patients below 3 years of age or who weigh less than 10 kg.

Women taking hormone-based birth control: Women should not rely only on hormone-based birth control, such as pills, injections, or implants, because Efavirenz may make these contraceptives ineffective.

Acute Overdose

Symptoms: Increased adverse CNS effects including involuntary muscle contractions. 

Management: Supportive and symptomatic treatment. May administer activated charcoal.
