Abstract :

The toxicokinetics of amitraz at 0.25 per cent was investigated in goats after single dermal application. Blood samples were collected at predetermined time intervals up to 168 h post dermal application. Analysis of amitraz was done by High Performance Liquid Chromatography. Amitraz was detected in blood from 0.5 h attaining a peak concentration of 7.24 0.79 at 6 h followed by a decline and persisted till 168 h. The various kinetic parameters were calculated using a two compartment open model. The absorption rate constant (t1/2Ka), apparent volume of distribution (Vd), elimination half-life (t1/2β), ratio of k12 and K21, tissue plasma ratio and mean residence time (MRT) were 1.19 h, 33.29mg/ L, 172.59 h, 0.63, 0.71 and 240.10 h respectively. Amitraz was rapidly absorbed from the site of application, widely distributed and slowly eliminated from the body. The lower tissue blood ratio suggested its minimum affinity for accumulation in tissue.
