Key Drug-Drug Interactions: What Every Clinician Mutt Know

Modulatory CFTR i Diabetes Medicinations

Several CFTR modulators are potent CYP hams or inducers. For example, lumacaftor is a strong inducer of CYP3A4, which can akcelerate the metabolize of mane drugs, including ding some or hypoglycemics (np., repaglinide) and corristesteroids. Conversely, ivacaftor and tezacaftor are moderate CYP3A inhibitors. If a patient on insulin, these modulatory effects may indiredirectly alter clearance of medicions, but indiredirecin iont.

For patients on repaglinide (a meglitinide), coadministrationin with lumacaftor- contening regimens can reduce repaglinide concentrations by up tu 50%, potentially requiring dose recrument or a switch to insulin.

Cortykosteroids andInsulin Requirements

Cortycosteroids (prednisone, methylprednisolone) are used in CF for allergic bronchopulmonary aspergillosis (ABPA) or during seare increbations.
