Abstract

Rilpivirine is a new non-nucleoside reverse transcriptase inhibitor (NNRTI) that is approved for HIV-1 treatment-naive adult patients in combination with other antiretroviral agents. The recommended dose is a 25 mg tablet once daily taken orally with a meal. Due to cytochrome P450 3A4 enzyme induction or gastric pH increase, rilpivirine cannot be coadministered with a number of other drugs (anticonvulsants, rifabutin, rifampicin, rifapentine, proton pump inhibitors, systemic dexamethasone and St John's wort). Rilpivirine should be used with caution when coadministered with a drug with a known risk for torsade de pointes. Rilpivirine has a better tolerability than a comparative NNRTI, efavirenz, in clinical trials, with fewer central nervous system adverse effects, rashes, lipid abnormalities and discontinuation rates. Virological failure occurs more commonly with higher baseline viral loads (>100,000 copies/mL) and lower baseline CD4 counts (<50 cells/mm(3)). Seventeen NNRTI mutations have been associated with decreased susceptibility to rilpivirine: K101E/P, E138A/G/K/Q/R, V179L, Y181C/I/V, H221Y, F227C, M230I/L, Y188L and the combination L100I + K103N. Resistance to rilpivirine largely excludes future use of the NNRTI class.
