[Study on pharmacokinetics of ginkgolide B injection in Beagle dogs].

OBJECTIVE: To study the pharmacokinetics of ginkgolide B injection in Beagle dogs. METHODS: Determined the serum concentration of ginkgolide B by LC-MS and calculated its parameter of pharmacokinetics via DAS 2.0 software. RESULTS: After intravenous drips of 0.62, 2.07 and 10.35 mg/kg ginkgolide B, parameters of pharmacokinetics of ginkgolide B were as follows: Tmax were 0.444, 1, 1 h; Cmax were 0.764, 3.024, 11.013 mg/L; AUC(0-1) were 1.007, 3.644, 16.646 mg x h/Lo. CONCLUSION: Ginkgolide B has two compartment model in Beagle dogs.
