Overview
11 DESCRIPTION EDURANT ® (rilpivirine) is a non-nucleoside reverse transcriptase inhibitor (NNRTI) of human immunodeficiency virus type 1 (HIV-1). The chemical name for rilpivirine hydrochloride is 4-[[4-[[4-[(E)-2-cyanoethenyl]-2,6-dimethylphenyl]amino]-2-pyrimidinyl]amino]benzonitrile monohydrochloride. Its molecular formula is C 22 H 18 N 6 ∙ HCl and its molecular weight is 402.88.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Rilpivirine is an antiviral drug [see Microbiology (12.4) ] . 12.2 Pharmacodynamics Effects on Electrocardiogram The effect of EDURANT at the recommended dose of 25 mg once daily on the QTcF interval was evaluated in a randomized, placebo and active (moxifloxacin 400 mg once daily) controlled crossover study in 60 healthy adults, with 13 measurements over 24 hours at steady state. The maximum mean time-matched (95% upper confidence bound) differences in QTcF interval from placebo after baseline-correction was 2.0 (5.0) milliseconds (i.e., below the threshold of clinical concern).
Indications
- 1 INDICATIONS AND USAGE EDURANT and EDURANT PED are a human immunodeficiency virus type 1 (HIV-1) specific, non-nucleoside reverse transcriptase inhibitor (NNRTI) indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in treatment-naïve patients 2 years of age and older and weighing at least 14 kg with HIV-1 RNA less than or equal to 100,000 copies/mL. ( 1.1 ). Limitations of Use: More EDURANT treated subjects with HIV-1 RNA greater than 100,000 copies/mL at the start of therapy experienced virologic failure (HIV-1 RNA ≥50 copies/mL) compared to EDURANT...
Common Doses

- 2.5 mg
- 12.5 mg
- 15 mg
Dosage
2 DOSAGE AND ADMINISTRATION One 25 mg EDURANT tablet taken once daily with a meal for patients weighing at least 25 kg. ( 2.2 ) Pediatric patients 2 years of age and older and weighing at least 14 kg to less than 25 kg: Dosage of EDURANT PED is based on body weight. ( 2.3 ) EDURANT PED must be dispersed in drinking water and taken with a meal. ( 2.4 ) Do not substitute EDURANT tablets and EDURANT PED tablets for oral suspension on a milligram-per-milligram basis due to differing pharmacokinetic profiles. ( 2.1 , 5.
Contraindications
- 4 CONTRAINDICATIONS EDURANT and EDURANT PED are contraindicated for coadministration with the drugs in Table 2 for which significant decreases in rilpivirine plasma concentrations may occur due to CYP3A enzyme induction or gastric pH increase, which may result in loss of virologic response and possible resistance to EDURANT or EDURANT PED or to the class of NNRTIs [see Drug Interactions (7) and Clinical Pharmacology (12.3) ] .
Side Effects
- 6 ADVERSE REACTIONS The following adverse reactions are discussed below and in other sections of the labeling: Skin and Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] Hepatotoxicity [see Warnings and Precautions (5.2) ] Depressive Disorders [see Warnings and Precautions (5.3) ] The most common adverse reactions to EDURANT or EDURANT PED (incidence >2%) of at least moderate to severe intensity (≥ Grade 2) were depressive disorders, headache, insomnia and rash.

Interactions
- 7 DRUG INTERACTIONS Rilpivirine is primarily metabolized by cytochrome P450 (CYP)3A, and drugs that induce or inhibit CYP3A may thus affect the clearance of rilpivirine. Coadministration of EDURANT or EDURANT PED and drugs that induce CYP3A may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance to rilpivirine or to the class of NNRTIs. Coadministration of EDURANT or EDURANT PED and drugs that inhibit CYP3A may result in increased plasma concentrations of rilpivirine.
