HIV Reports

In 188 HIV-infected children receiving efavirenz, a lower mid-dose (C12) was associated with a higher risk of HIV-1 viral load >400 copies/mL (P = 0.03). Simulations for a normalized population receiving US Food and Drug Administration weight-band dosing predicted that 15% of children would have a C12 below target threshold (<1.0 mg/L) with a 23% risk of viral replication.
