Chemical composition and pharmacological properties

BARS® drops against fleas and ticks for cats contain fipronil - 10 mg/ml, diflubenzuron - 1 mg/ml and dicarboximide (MGK 264) - 1 mg/ml (as active ingredients), as well as excipients.

The mechanism of fipronil action (a component of the drug) includes blocking the GABA-dependent receptors of ectoparasites, which impairs the neural impulse transmission causing paralysis and death of ectoparasites. Diflubenzuron, by means of inhibiting the chitine synthesis in parasites, impairs of molting, egg production, and egg hatchability processes terminating the population growth and sustaining. Dicarboximide acts as a synergic drug and is commonly combined with insecticides to increase its efficiency. Dicarboximide prevents microsomal detoxification of insecticides increasing its toxicity for parasites.
