吡喹酮注射液在健康水牛體內(nèi)的藥物動(dòng)力學(xué)
[Abstract]:Objective to study the pharmacokinetic characteristics of praziquantel injection in buffalo and its relative bioavailability with praziquantel tablets. Methods six healthy adult buffaloes were used in a two-cycle randomized crossover design. Praziquantel tablets (20 mg/kg) or praziquantel injection (10 mg/kg) were administered intramuscularly. The concentration of praziquantel in buffalo plasma was determined by high performance liquid chromatography (HPLC). The non-atrioventricular model was analyzed and pharmacokinetic parameters were calculated. Results the peak time (T _ (max) of praziquantel tablet was (0.60 鹵0.29) h, the peak concentration (C _ (max) was (0.57 鹵0.37) 渭 g / ml, the elimination half life (T _ (1 / 2 尾) was (0.70 鹵0.42) h, and the area under the drug-time curve was (0.80 鹵0.70) (渭 g/ml) h. The T _ (max) of praziquantel injection was (0.65 鹵0.49) (max) (3.82 鹵1.17) 渭 g 路ml ~ (-1) T _ (1 / 2 尾) was (1.00 鹵0.73) HPA = (1.61 鹵0.89) (渭 g/ml) h. The bioavailability of praziquantel injection was 402.5. Conclusion praziquantel injection has the characteristics of rapid absorption, high bioavailability and wide distribution in the body of buffalo after intramuscular injection. The recommended dosage of praziquantel injection is 10 mg / kg.
