In Vivo Three monthly treatments with Selamectin/sarolaner provide high and consistent efficacy against I. ricinus for the entire duration of the study period. The percentage efficacy against I. ricinus is numerically higher in the Selemectin/sarolaner treating group than in the fluralaner-treating group on Days 56, 84 and 91[1]. All dogs are tested negative by both tests after receiving topical treatment with Selamectin monthly for 36 months[2].
Animal Admin The cats are weighed on Days-2, 29 and 58 to calculate the dosing. Cats in group 1 (control group) remain untreated. On Day 0, the cats in group 3 are treated with fluralaner at the minimum recommending label dose of 40.0 mg per kg body weight. On Days 0, 30 and 60, the cats in group 2 are treated with the new spot-on formulation at the minimum recommending label dose of 1.0 mg/kg sarolaner and 6.0 mg/kg Selamectin. The cats are observed at different time points after treatment for possible adverse reactions to treatment. On Day 0, administration site observations are performed on all cats 30 min (±5 min), 3 h (±15 min) and 24 h (±1 h) and again on Days 3 and 5 after treatment[1].
