Midazolam Theophylline

Drugs that may be affected by telithromycin include cisapride, digoxin, ergot alkaloids, metoprolol, midazolam, pimozide, HMG-CoA reductase inhibitors, sotalol, and theophylline. 

Drugs that might be affected by lopinavir/ritonavir include ergot derivatives, oral contraceptives, antiarrhythmics, HMG-CoA reductase inhibitors, HIV protease inhibitors, atovaquone, calcium channel blockers, ketoconazole, itraconazole, pimozide, cisapride, clarithromycin, disulfiram, metronidazole, immunosuppressants, midazolam, triazolam, narcotic analgesics, rifabutin and rifabutin metabolite, sildenafil, warfarin, bupropion, clozapine, desipramine, piroxicam, quinidine, theophylline, and zolpidem. 

Values were back calculated from actual in vivo DDI data for fluconazole and S-warfarin (fee, CYP2C9 = 0.91), fluvoxamine and theophylline (fcL,CYPiA2 = 0.8), fluvoxamine and S-mephenytoin (fcL,CYP2C9 = 1). ketoconazole and midazolam fcL,CYP3A,hepatic = 0.93), and quinidine and desipramine (fcL,CYP2D6 = 0.9). 

The importance of these enzymes for drug interactions is that enzyme inducers and inhibitors may preferentially affect certain isoforms and consequently may only affect the metabolism of selected drugs. For example, ketoconazole has the potential to inhibit the metabolism of drugs metabolised to a great extent by the sub-family 3A (e.g. midazolam) but not of those metabolised by sub-family 1A (e.g. theophylline), 2C (e.g. diazepam), or 2D (e.g. metaprolol). In contrast, although fluconazole is a weaker inhibitor of the sub-family 3A than ketoconazole, it also inhibits the sub-family 2C, and so the interactions of fluconazole differ from those of ketoconazole.
