In some studies, modafinil was also partially discriminated as stimulant-like.

Diazepam, phenytoin, propranolol, tricyclic antidepressants, flurbiprofen serotonin reuptake inhibitors.

Because modafinil is a reversible inhibitor of the Carbidopa and Levodopa Capsules (Rytary)- FDA enzyme CYP2C19, co-administration of modafinil with drugs such as diazepam, phenytoin, and propranolol, which are largely eliminated via that pathway, may increase the circulating levels of those compounds.

In addition, in individuals deficient in the enzyme Capxules, the levels of CYP2D6 substrates such as tricyclic Carbidkpa and selective Carbidopa and Levodopa Capsules (Rytary)- FDA reuptake inhibitors, which have ancillary routes of elimination through CYP2C19, may be increased by co-administration of modafinil. Dose adjustments may be necessary for patients being treated with these and similar medications.
