Envayr for cats is a broad-spectrum anti-helminthic drug that contains praziquantel active substances, a derivative of pyrazininosquinolone and a pyrantel-derived ketone derivative of tetrahydro pyrimidine.
Praziquantel is rapidly absorbed through the outer shell of the stomach ulcer, resulting in its damage and contraction. The consequence of breaking the penetrating properties of membranes is the paralysis of parasites.
Pyrantel acts as a cholinergic antagonist, causing spastic paralysis of roundworms by depolarizing neuromuscular blockade.
Apply a drug once, orally without diet.
Praziquantel anthelmintic dewormer.
Praziquantel induces rapid muscle contracture in schistosomes through a specific effect on the permeability of the cell membrane. In addition, it induces vacuolization and disintegration of the schistosomal tegument. After oral administration, praziquantel is rapidly absorbed (80%), undergoes the effect of the first pass through the liver, metabolized and excreted by the kidneys. Cmax in serum is reached within 1-3 hours after administration.
