RESUMO
This preliminary study evaluated phenoxymethyl penicillin (Penicillin V) as an alternative to parenteral administration of penicillin in horses. Penicillin V was administered orally to five horses at two different doses and plasma levels of the drug were determined at timed intervals. The results were evaluated by regression analysis. Following the administration of penicillin V at a dose of 66,000 IU/kg or 110,000 IU/kg, the mean peak plasma levels obtained were 1.55 micrograms/mL and 2.34 micrograms/mL respectively. A plasma level two to four times above the minimal inhibitory concentration level of Streptococcus equi and Streptococcus zooepidemicus was maintained for 325 minutes at 66,000 IU/kg and 349 minutes at 110,000 IU/kg. Penicillin V given orally was thus shown to be an acceptable alternative to parenteral administration of penicillin in the horse.
