ABSTRACT
Parkinsonism is a neurodegenerative disease that is defiend by certain symtom as muscle rigidity , impaired movement , tremor and disorientation of body. The aim of the present study was to compare the efficacy of selegiline and bromocriptine in the prevention of experimentally induced pseudoparkinsonism in rat. Perphenazine (5mg/kg) was used (IP) as the inducing agent. Different groups of rats were pretreated by either selegiline (2.5, 5, 10, and 20mg/kg), or effective dose of bromocriptine (30mg/kg). The degree of prevention of catatonic reaction was compared with control group. The results showed all selegiline-treated groups had significant reduction in the catatonic reaction relative to sham treated group. In addition, 20mg/kg selegiline had more intensive effect to reduce the catatonic reaction than bromocriptine (30mg/kg). Selegiline seems to be a suitable drug to prevent perphenazine–induced catatonia in rat..
