Reporting Groups
  Description
DRV/Rtv Before dose adjustment, oral darunavir suspension (100 mg/mL): 20 mg per kg body weight twice daily for children weighing between 10 and <20 kg. After dose adjustment, 25 mg per kg body weight twice daily if weight less than 15 kg, and fixed dose of 375 mg twice daily if weight more than or equal to 15 kg. Before dose adjustment, oral ritonavir solution (80 mg/mL): 3 mg per kg body weight twice daily and after dose adjustment fixed dose of 50 mg twice daily if weight more than or equal to 15 kg
