RESUMO
Neomycin sulfate was administered to calves by the intravenous and intramuscular routes. Serum drug levels were determined and the intravenous pharmacokinetic parameters derived using the Gauss-Newton nonlinear fitting algorithm and the two compartment open model. The kinetic parameters determined were as follows: zero time intercept, serum drug level 68.045 +/- 15.894 micrograms/mL, alpha slope intercept 37.666 +/- 13.874 micrograms/mL and beta slope intercept 30.379 +/- 12.638 micrograms/mL; equilibration rate (pool I and II) 0.081 +/- 9.064 min-1; elimination rate 0.004 +/- 0.001 min-1; half-time alpha 14.774 +/- 11.236 min, half-time beta 166.596 +/- 47.576 min; first order elimination constant 0.009 +/- 0.002 min+; transfer rate constants, central to peripheral, 0.032 +/- 0.026 min+ and peripheral to central 0.045 +/- 0.037 min-1; volume of central compartment 0.186 +/- 0.047 L/kg; volume of distribution 0.388 +/- 0.130 L/kg; body clearance 0.002 +/- 0.001 L/kg/min.
