title: Effect of food on cibenzoline bioavailability.
abstract: Eighteen healthy adult volunteers received 160 mg oral capsule doses of cibenzoline in an open-label, four-way randomized crossover study designed to determine the influence of food on cibenzoline pharmacokinetics. Cibenzoline was administered 1 h prior to, with, and 1 h following a standard breakfast as well as under fasting conditions. There was no change in any bioavailability parameter when the data following drug ingestion 1 h prior to food were compared to the fasted state. Bioavailability parameters obtained when drug was taken during the meal or 1 h after the meal suggested that the rate of absorption was slightly decreased in the presence of food, while the extent of absorption was unaltered. The decreased absorption rate in the presence of food is not expected to be of clinical significance. The presence of food is not expected to affect the bioavailability of cibenzoline to the extent of clinical significance.
