A study was carried out to describe the pharmacokinetic disposition of pentavalent antimony generic ulamina in 8 healthy dogs in acute intravenous and intramuscular test after a dose of 25mg/Kg. The curves obtained for both routes show a decrease in plasma concentrations of 184.91 ± 86.06 μ g / mL to 86.06 ± 39.24 μ g / mL and 164.61 ± 23.80 μ g / mL to 100.94 ± 45.3, μ g / mL to 4.0 hours for the IM and IV, respectively, corresponding to the alpha phase distribution. There was a decrease slowly, with antimony detectable beyond 24.0 hours for both routes, called beta or disposal. The drug is rapidly absorbed and showed high bioavailability. The half life (t1/2β) IV was 8.1 hours and t1/2β IM was 13.35 hours. The volume of distribution (Vd) IV was 0.17 L /Kg and MI was 0.23 L /Kg. No significant differences were found when comparing AUC, and t1/2β, after IV and IM administration ulamina, proposing the latter as a more practical and safe administration route. The ulamina may be a therapeutic option for the treatment of human and canine leishmaniasis, as it is suggested by the application of multiple dose trials to evaluate the phase of removal and to determine if there is an accumulation of antimony, which would warrant a dose reduction.
