Effect of milk on absorption of norfloxacin in healthy volunteers.
The authors studied the effect of milk on the bioavailability of norfloxacin in six healthy male volunteers in a randomized crossover trial. After an overnight fast, 200 mg of norfloxacin was given with 200 mL of water or milk. Area under the curve (AUC) of norfloxacin with milk was significantly (P < 0.01) smaller than that with water. The mean peak serum concentration was decreased to 60% after oral administration of norfloxacin with milk (P < 0.01). The apparent volume of distribution at central compartment (Vc/f) value of norfloxacin was significantly (P < 0.05) increased with milk. Milk exhibits a clinically significant effect on norfloxacin absorption.
