Parametric population pharmacokinetics of isoniazid: a systematic review.

Compared with slow metabolizers, the daily dose of INH should be increased by 200-600mg in fast metabolizers. To achieve effective treatment, pediatric patients need a higher dose per kilogram than adults. Further PPK studies of anti-tuberculosis drugs are needed to comprehensively understand the covariates that affect their PK characteristics and to achieve accurate dose adjustments.
