Resumo
Dexamethasone induces CYP3A4 and may substantially reduce lapatinib exposure, risking loss of efficacy. Lapatinib may modestly raise dexamethasone exposure through CYP3A4 and P-glycoprotein inhibition.
O que esta interação significa em palavras simples
Dexamethasone-neomycin-polymyxin and Lapatinib can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Dexamethasone-neomycin-polymyxin belongs to Anti Bacterial; Lapatinib belongs to Oncology.
Por que acontece
Dexamethasone induces CYP3A4 and increases lapatinib clearance, while lapatinib weakly inhibits CYP3A4 and P-glycoprotein.
O que fazer
Avoid prolonged systemic dexamethasone with lapatinib where possible, or consider a lapatinib dose increase per labeling for strong inducers. Monitor tumor response and corticosteroid effects.
