Overview

**Vorasidenib + ciprofloxacin** is a drug combination with significant pharmacokinetic interaction. Vorasidenib is an orally administered, brain-penetrant small molecule dual inhibitor of mutant isocitrate dehydrogenase 1 and 2 (IDH1/2), developed as a targeted therapy for grade 2 astrocytoma or oligodendroglioma with IDH1 or IDH2 mutation[1][4][5]. Ciprofloxacin is a fluoroquinolone antibacterial and acts as a moderate CYP1A2 inhibitor. When co-administered, ciprofloxacin substantially increases plasma concentrations of vorasidenib (Cmax by 1.3-fold and AUC by 2.5-fold) due to CYP1A2 inhibition, raising the risk of vorasidenib-related adverse reactions[1][3][4][5]. This combination should generally be avoided unless benefits clearly outweigh risks.
