PG - 474-476 LID - 10.4103/jcrt.jcrt_533_22 [doi] AB - Pazopanib is an oral multitargeting tyrosine kinase inhibitor (TKI) of vascular endothelial growth factor receptors (VEGFRs), approved as the first-line treatment of metastatic renal cell carcinoma (mRCC) and soft tissue sarcoma (STS) at a fixed dose of 800 mg daily taken fasted. Potential drug-meal interactions and adverse events (AEs) may lack recognition and the related data in literature. We report one case of stomatitis/oral mucositis associated with pazopanib administrated with an oral nutritional supplement enriched with omega-3 fatty acids. The 50-year-old patient with mRCC started pazopanib treatment at standard doses of 800 mg daily as first-line therapy for mRCC, and after a few days, he developed stomatitis. Co-administration of pazopanib with high-fat meals could increase the solubility of highly lipophilic pazopanib, increasing its plasma pazopanib area under the curve (AUC), and maximum concentration (Cmax) above optimal therapeutic level can consequently lead to increased frequency/grade of AEs.
