Tolerability research of complex antiparasitic preparation «Inspector collar»

Objective of research: To evaluate the tolerability of the drug, “Inspector Collar” based on Fipronil, Pyriproxyfen and Ivermectin in dogs and cats applied at a therapeutic dose and double increased therapeutic doses. Materials and methods: Research was conducted at the shelter for dogs and cats «Bano Eco» (Moscow). Effect of drug “Inspector Collar” was studied on 15 clinically healthy outbreed dogs between 2 and 6 years with the body mass of 10–14 kg and 15 clinically healthy outbreed cats between 2 and 4 years with the body mass of 2–3,5 kg, receiving complete and balanced nutrition. Animals were divided into six groups (three groups of dogs and three of cats) five animals in each group. Dogs and cats from the first experimental group had put on one collar (equivalent of single therapeutic dose) for 45 days. The second experimental group had put two collars (double therapeutic dose) for 45 days. Animals from the third (control) group did not carry collars. During the experiment, daily supervision of animals was conducted; their general health status, behavior, appetite were observed, body mass and temperature estimated. Before and 15 and 30 days after the beginning of drug application, blood and urine tests were performed to study morphological and biochemical parameters. Statistical processing of data were carried out using Student’s t-test. Results and discussion: The research results showed that the drug “Inspector Collar” is well tolerated even at double therapeutic dose. All observed indicators remained within the physiological norm.
