Expert Committee recommendation
The Expert Committee recommended the deletion of isoniazid 50 mg tablet (scored) from the EML and EMLc as requested in the application, noting that it is not an optimal, appropriate formulation for the treatment of tuberculosis, in line with recommendations in the current WHO tuberculosis treatment guidelines. The Committee recognized that dispersible tablet formulations are the preferred child-friendly formulations and provide flexible dosing options. However, because of concerns about limited uptake and availability of dispersible-tablet formulations of isoniazid in some countries, the Committee did not recommend the deletion of the oral liquid formulation isoniazid at this time. To allow countries time to transition to the adoption of the preferred, listed dispersible-tablet formulations, the Committee advised that this formulations will be deleted from the Model Lists without further consideration in 2023, unless an application is received to support its retention.
