                                Montelukast + Phenytoin
                            
                        

                        
                        
Phenytoin, a potent CYP inducer, can increase the metabolism of montelukast, potentially reducing its plasma levels and therapeutic efficacy.

                                Montelukast + Fluconazole
                            
                        

                        
                        
Fluconazole inhibits CYP2C8-mediated metabolism of montelukast, modestly increasing montelukast plasma concentrations; the clinical impact is generally minor given montelukast's wide therapeutic index.
