Antibiotics such as doxycycline, rifampicin, and azithromycin demonstrate anticancer properties by inhibiting angiogenesis, inducing apoptosis, and regulating key pathways including the interleukin (IL)-6 signaling pathway and autophagy-related pathways. By elucidating the pivotal role of biofilms in persistent infections and highlighting untapped therapeutic opportunities in antibiotic repurposing, this review underscores a transformative approach to cancer treatment. This article explores the potential of repurposing antibiotic drugs for cancer treatment and highlights the prospects of drug repurposing strategies.
Pharmacokinetic (PK) studies were performed in Sprague-Dawley (SD) rats following oral and intravenous dosing, including coadministration with CYP3A4 inhibitors (voriconazole, itraconazole) and inducers (rifampicin, carbamazepine). Significant interspecies differences between HLM and RLM emphasize the need for caution when translating preclinical findings. Coadministration with CYP3A4 modulators markedly altered systemic exposure, while effective brain penetration supports its therapeutic role in central nervous system (CNS) metastases.

The PBPK model captured the clinically observed interactions for itraconazole, rifampin, and midazolam, with predicted pirtobrutinib and midazolam AUC ratios within 0.91- to 1.16-fold of observed. Furthermore, the predicted pirtobrutinib AUC ratios were within 0.51-0.86 with moderate and weak CYP3A4 inducers. The predicted effects of CYP3A4 modulators on pirtobrutinib pharmacokinetics, together with the known exposure-response relationships for safety and efficacy in patients with hematological malignancies, were used for recommending appropriate dosing regimens during coadministration.
