In children, nevirapine elimination accelerates during the first years of life, reaching a maximum at around 2 years of age, followed by a gradual decline during the rest of childhood. doi: 10.1097/INF.0000000000000603.Med J Armed Forces India.

Nevirapine elimination accelerates during long term administration because of autoinduction of the enzymes involved in its elimination pathway. Von Hentig N, Carlebach A, Gute P, Knecht G, Klauke S, Rohrbacher M et al (2006) A comparison of the steady-state pharmacokinetics of nevirapine in men, nonpregnant women and women in late pregnancy.

Pharmacokinetics of nevirapine metabolites. It is taken by mouth.

The primary route of nevirapine elimination is through metabolism by the cytochrome P450 enzyme system. 2011 Mar;11(3):171-80. doi: 10.1016/S1473-3099(10)70288-7. Unable to load your collection due to an error Nevirapine pharmacokinetics are characterised by rapid absorption and distribution, followed by prolonged elimination. It may be used to prevent mother to child spread during birth but is not recommended following other exposures.

There are few data describing the safety and pharmacokinetics of nevirapine during long term use in pregnancy. Maximum nevirapine plasma concentrations are achieved at about 4 h after drug administration, and the absolute bioavailability is 93% for the tablet formulation (Nevirapine is extensively metabolized in the liver by cytochrome P450 (CYP) isoenzymes 3A4 and 2B6, and is mainly excreted into the urine as glucuronidated and hydroxylated metabolites (80%) and as parent drug (5%) [Population pharmacokinetic analyses have identified several covariates that may contribute to the observed interindividual variation in the pharmacokinetics of nevirapine (The steady‐state plasma pharmacokinetics of nevirapine after administration of 400 mg once‐daily and 200 mg twice‐daily was investigated in a randomized, balanced, two‐way cross‐over bioequivalence study in 20 HIV‐1‐infected patients [ Median steady‐state plasma concentration vs time curves of nevirapine in 20 HIV‐1‐infected patients after administration of nevirapine 400 mg once‐daily (solid circles) and 200 mg twice‐daily (open circles) [The exposure to nevirapine, measured as the area under the plasma concentration vs time curve from 0 to 24 h (AUCThe median nevirapine plasma concentration at the end of the dosing interval (A number of studies have explored the relationships between the pharmacokinetics of nevirapine and the virological response to therapy (The INCAS study demonstrated a positive relationship between nevirapine concentrations and virological response [Several studies have evaluated the relationship between elevations in liver enzymes and nevirapine concentrations.
In the context of attempts to simplify treatment regimens and enhance adherence, there is great interest in once‐daily dosing regimens for the treatment of HIV‐1 infection. 2017 Aug 21;12(8):e0183080. The recommended regimen for adults is nevirapine 200mg once daily for 2 weeks, followed by 200mg twice daily.
