Tương tác
H2 antagonists (e.g. cimetidine, ranitidine) may decrease the absorption of rilpivirine. Increased plasma concentration with CYP3A inhibitors (e.g. erythromycin).
Potentially Fatal: Significantly decreased plasma concentration with carbamazepine, oxcarbazepine, phenobarbital, phenytoin, dexamethasone, rifampicin, rifapentine. Reduced absorption due to increase in gastric pH with omeprazole, esomeprazole, lansoprazole, pantoprazole, rabeprazole.
Food Interaction
Increased absorption with food. Decreased plasma concentration with St. John’s wort. Increased exposure with grapefruit products.
Tác dụng
Description: Rilpivirine is a 2nd generation diarylpyearsimidine non-nucleoside reverse transcriptase inhibitor (NNRTI), which inhibits HIV-1 from binding to reverse transcriptase, leading to reduced viral DNA synthesis.
Pharmacokinetics:
Absorption: Increased absorption by approx 40% with normal to high-caloric meal. Time to peak plasma concentration: 4-5 hours.
Distribution: Plasma protein binding: 99.7%, primarily to albumin.
Metabolism: Metabolised in the liver via oxidation by CYP3A4 isoenzyme pathway.
Excretion: Mainly via faeces (85%, approx 25% as unchanged drug); urine (approx 6%, <1% as unchanged drug). Terminal elimination half-life: Approx 50 hours.
