Generic Name: Efavirenz
What is Efavirenz?
Since these specific dose amounts are not achievable with existing market formulations, simulated exposures for EFV daily doses of 300 mg, 450 mg, and 600 mg are presented in Table 5 to reflect similar doses that are achievable with the currently existing formulations. Mean SD change from baseline CD4 counts at days 84, 168 and after 200 days of EFV based ART was 93. AUC values for these 6 patients, as well as their baseline and day 84 HIV RNA values are presented in Table 6. In part this may be because the pharmacodynamics response is so strong for most patients at all observed exposure levels on this combination HAART therapy.
Despite the existing evidence of extensive inter-ethnic EFV pharmacokinetic variability that is dependent on host-genetic-factors, its dosing in the sub-Saharan African region is to date based largely on data derived from studies conducted among Caucasians. We predicted EFV optimal dose for adult HIV-1 infected Ugandans based upon population genetic make-up and recommend a dose reduction from 600 mg to 450 mg daily dose.
Presumably the supra-therapeutic EFV exposure might play a role in adherence issues and consequent treatment outcomes of EFV based ART. Successful HIV viral suppression has been demonstrated at EFV doses of 400 mg and 200 mg daily among patients that exhibited supra-therapeutic plasma concentrations following 600 mg daily EFV dose.
The current study had a long follow up period of up to 252 days and pharmacokinetic data were collected at assumed steady state conditions.
