Summary of evidence and Expert Committee recommendations
There are no international data publicly available that describe the prevalence and incidence of TB in children under 15 years of age, and few clinical trials of treatment on children. However, TB is accepted as a public health priority and therefore treatment of it fulfi ls the criteria for essential medicines. All four medicines used in standard treatment are licensed for use in children. The EMLc Subcommittee endorsed all four and noted that an oral liquid form of all of them was available. The Subcommittee recommended that all of these single agents be added to the List (ethambutol 25 mg/ml, isoniazid 50 mg/5 ml, pyrazinamide 30 mg/ml, rifampicin 20 mg/ml).
