- Primary Outcome Measures
Name Time Method Investigate pharmacokinetic patterns of Efavirenz in children infected HIV older than 3 years and less than 13 years old, weighing from 7.5 to 35 kg;;To evaluate the safety and efficacy of the treatment by the incidence of events adverse clinical and laboratory, and the reduction in CV (viral load) and increase in immune response (CD4 increase);
- Secondary Outcome Measures
Name Time Method Describe pharmacokinetic parameters Efavirenz through blood sampling for 21 and 42 days respectively by treatment with the liquid formulation or dispersible tablets starting from a crossover design (all 75 participants will use 21 days liquid formulation and 21 days tablets dispersible order Random;;Evaluate the pharmacokinetic variability, intra and inter volunteers (eg, age) of Efavirenz in the pediatric formulation compared to the liquid formulation; describe any adverse reactions attributed to the pediatric formulation testing and liquid formulation by capturing adverse events during the participation of volunteer in the study;; evaluate the influence of genetic polymorphism of CYP 2B6 enzyme in EFZ clearance between Brazilian children;
