Effect of food on the bioavailability of 100-mg dilantin Kapseals

The authors examined the effect of food on the bioavailability of Dilantin Kapseals in a nonblinded, single 100-mg dose, randomized, crossover trial. Drug was administered after an 8-hour fast and after a high-fat meal. Differences in mean dietary state values were +6% for maximum concentrations (C(max)) and -2% for area under the curve. Associated 90% CI were within US Food and Drug Administration criteria, confirming the absence of a food effect. Thus, patients may take 100-mg Dilantin Kapseals without regard to meals.
