INTERVENTIONAL
Conditions
Summary

Interventions
A triple dose is defined as the triple of the routine dose used for a specific WHO weight band. Hence, the mg/kg within a weigh-band varies, as is the case in routine practice. Dosing takings into consideration the fixed dose combination (FDC) tablets (one tablet: 150 mg R + 75 mg H + 400 mg Z + 275mg E). Dosage relies on tables with dosage by weight-bands used by WHO for the Cat. 1 regimen. The dosage used for the intensive phase of the Cat. 1 regimen applies for the whole treatment duration. A double dose of H and R is added to the recommended normal dose for adults (WHO,2003)
Recommended normal dose adults (WHO, 2003) * H: 5 (4-6) mg/kg/day * R: 10 (8-12) mg/kg/day * Z: 25 (20-30)mg/kg/day * E: 15 (15-18)mg/kg/day
