Effect of two types of Indian breakfast on bioavailability of cefuroxime axetil.
OBJECTIVE
The oral bioavailability of cefuroxime axetil is enhanced by food. This study was done to compare the effect of two types of Indian breakfast on the bioavailability of cefuroxime axetil in healthy volunteers.


METHODS
Eight healthy male volunteers participated in the crossover study. Subjects were randomized to receive either one of the two types of breakfast, Diet-A or Diet-B, 10 min before single dose of 500 mg cefuroxime axetil. After a washout period of one week the study was repeated with the other type of diet. Diet-A included idly with chutney. Diet-B included poori and dal-fry. Blood samples for pharmacokinetic analysis were obtained prior to dosing and at 0.25, 0.50, 0.75, 1.0, 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, 6.0 and 8.0 h following dosing and urine collections were done for 8 h. The serum and urine samples were assayed by using HPLC.


RESULTS
The AUC and Cmax were significantly increased after oral administration of cefuroxime axetil with Diet-B, when compared to Diet-A (P < 0.01 and P < 0.02 respectively). The values of apparent absorption rate constant, lag-time, Tmax and t1/2 beta for the two regimens were not significantly different. The volume of distribution and plasma clearance for cefuroxime were significantly lower (P < 0.02, P < 0.001 respectively) in the regimen with Diet-B. The 8 h urinary recovery of cefuroxime was 16.59 and 28.44 per cent (P < 0.005) with Diet-A and Diet-B respectively.


CONCLUSIONS
The administration of cefuroxime axetil with poori and dal-fry may enhance the bioavailability when compared with idly and chutney.
