Description: Rilpivirine is a pharmaceutical drug, developed by Tibotec, for the treatment of HIV infection. It is a second-generation non-nucleoside reverse transcriptase inhibitor (NNRTI) with higher potency, longer half-life and reduced side-effect profile compared with older NNRTIs, such as efavirenz. Rilpivirine entered phase III clinical trials in April 2008, and was approved for use in the United States in May 2011. A fixed-dose drug combining rilpivirine with emtricitabine and tenofovir, was approved by the U.S. Food and Drug Administration in August 2011 under the brand name Complera.

Biological target: Rilpivirine is a potent and specific diarylpyrimidine (DAPY) non-nucleoside reverse transcriptase inhibitor (NNRTI) that has high antiviral activity against wild-type HIV (EC50=0.4 nM) and mutant viruses (EC50=0.1-2.0 nM).
In vitro activity: The results from this study show that rilpivirine and estradiol either alone or in combination or pretreated with β-naphthoflavone can evoke marked effects on glycerol and cytokines levels from adipocytes. Reference: Mol Biol Rep. 2019 Jun;46(3):2643-2655. https://pubmed.ncbi.nlm.nih.gov/30927158/
In vivo activity: This study indicates the importance of maintaining rilpivirine at a sustained threshold after HIV exposure to prevent dissemination of HIV-1 after vaginal infection and low-frequency resistance mutations conferred low-level resistance, suggesting that rilpivirine resistance is difficult to develop after HIV-1 infection during rilpivirine preexposure prophylaxis.
