Se evaluó la eficacia de dos formulaciones de oxfendazol (OFZ) contra cisticercosis producidas localmente, al 22,5% y 10% en comparación con una formulación comercial (Synanthic 9,06%) en 22 cerdos naturalmente infectados, que recibieron una dosis oral de 30 mg/kg. Los cerdos fueron sacrificados a las ocho semanas postratamiento para evaluar quistes en en sus carcasas, y se determinó la eficacia cisticida a través de la proporción de quistes degenerados sobre el total. Solo se encontraron quistes degenerados en la musculatura, corazón y lengua de los cerdos tratados con OFZ en todos los grupos, lo cual muestra una eficacia del 100%. En los cerebros se encontraron quistes viables y degenerados, con una eficacia menor en todos los grupos (65% [OFZ comercial], 47% [OFZ local 22,5%] y 31% [OFZ local 10%], p = 0,355. Las formulaciones de OFZ producidas localmente fueron igual de efectivas que la formulación comercial y pueden proporcionar una alternativa para el tratamiento de la cisticercosis porcina.
The efficacy of two locally produced oxfendazole (OFZ) formulations against cysticercosis at 22,5% and 10%, versus a commercial formulation (Synanthic 9,06%) was evaluated in twenty-two naturally infected pigs that received a single oral dose of 30 mg/kg. Pigs were sacrificed at eight weeks post-treatment to evaluate the cysts found in their carcasses, and to determine the cysticidal efficacy, which was defined as the proportion of degenerated cysts over total cysts. Only degenerated cysts were found in muscle, heart, and tongue of pigs treated with OFZ in all groups, which shows an efficacy of 100%. Viable and degenerated cysts were found in brains, being the efficacy lower in all groups (65% [commercial OFZ], 47% [local OFZ 22.5%] and 31% [local OFZ 10%], p = 0.355). Locally produced OFZ formulations were similarly effective to the commercial formulation and may provide a practical alternative for the treatment of porcine cysticercosis.
