Abstract:
OBJECTIVE: To study the pharmacokinetics of infusion Etimicin in the patients with respiratory tract infec- tions. METHODS: Ten patients were infused with 200mg Etimicin and the concentrations of drug in the plasma, urine and sputurn were determined by microbiological method. RESULTS & CONCLUSlON: The peak concentration of plasma was 17.74?g/ml. The concentration of 0.29?g/ml maintained 12h after administration. Pharmacokinetics parameters conformed to two - compartment model. The pharmacokinetics parameters were, T1/2?= 0. 257h, T1/2? = 2. 22h, Vc = 34. 32L, K2l = 2.14h~(-1), K12 = 0. 48h~(-1), K10 = 0.39h~(-1). The cumulative percentage of renal excretion was 21.37% within 12h, Ke =0. 027h~(-1), K = 0. 431h~(-1). The drug concentration in sputum reached the peak of 2.09?g/ml 2h after infusion.
