The aim of this work was to determine the pharmacokinetics of intravenous (iv) and intramuscular (im) ceftazidime administered to lactating (LTG; n = 6) and non-lactating (NLTG; n=6) healthy Creole goats in 2 trials (T1 and T2). During T1 and T2, goats randomly received a single dose of im or iv ceftazidime (10 mg/kg). Serum concentration of iv ceftazidime in NLTG and LTG goats is best described by 2 and 3 compartment models, respectively. The pharmacokinetic parameters of iv and im ceftazidime administered to LTG and NLTG showed statistically significant differences (P<0.05) in the constants (λz, T1 vs T2 [iv] 0.5±0.1 vs 0.3±0.1 /h; T1 vs T2 [im] 0.5±0.2 vs 0.3±0.1 /h) and in the mean times (t1/2, T 1 vs T 2 [iv] 1.6±0.3 vs 2.3±0.6 h; T 1 ...
