| The study analyzed the effect of mannitol on the pharmacokinetics (PK) of amikacin. Adult Wistar rats were treated as follows: Group 1 (G1) received mannitol for three days, Group 2 (G2) received mannitol plus 10 mg/kg of amikacin simultaneously, and Group 3 only amikacin. The PK study was conducted on the 4th day. For which, blood samples were drawn at fixed times during 24 h and immunoenzymatically analyzed. Results revealed significant differences (p<0.05) between the groups, e.g. Cmax were 62.26 ± 15.75 µg/ml for G1, 72.63 ± 24.80 µg/ml for G2 and 68.61 ± 27.40 µg/ml for G3. The AUC also differed in the three groups, being largest for G2, 222.52 ± 47.30 µg/ml/h, and smallest for G1, 135.59 ± 39.00 µg/ml/h. Alteration of the PK parameters observed... |
