Limited research on how rifampicin, a drug for tuberculosis, moves through the body and into the brain in children with tuberculous meningitis (TBM) inspired this analysis of its distribution in cerebrospinal fluid (CSF) and brain tissue.
The study involved 61 children, aiming to quantify rifampicin levels in plasma, lumbar CSF, ventricular CSF, and brain extracellular fluid using advanced techniques like liquid chromatography and microdialysis.
Findings revealed that rifampicin concentrations are significantly lower in CSF than in plasma, confirming that the drug penetrates brain tissue and suggesting microdialysis as a useful method for studying drug distribution in TBM.
