Table 1 provides a comprehensive list of drugs that can affect phenytoin concentrations in the body. These drugs are categorized into three groups: drugs that may increase phenytoin serum levels, those that may decrease phenytoin serum levels, and drugs that may either increase or decrease phenytoin levels. Some examples of drugs in these categories include antiepileptic drugs like carbamazepine and valproate sodium, antineoplastic agents like capecitabine and doxorubicin, azoles such as fluconazole and itraconazole, antidepressants like fluoxetine and sertraline, and other agents like diazepam, warfarin, and St. John's wort.
