Screening of antiepileptic drugs : The PTZ-assay in the mice
Epilepsy is a disease characterized by recurrent seizures that effects more than sixty million people worldwide. Available treatments can only partially control the disease and are associated with severe side effects, the search for more effective and safer drugs for controlling seizures therefore remains a crucial challenge for the Pharmaceutical industry.
Pentylenetetrazole (PTZ) –induced seizures in mice is an accepted in-vivo model for the screening of antiepileptic drugs. Seizures are induced by the administration of 100 mg/kg, s.c. PTZ and the mice are then observed for a 60 minute period.
Anticonvulsant drugs are usually tested in this model but other treatments could also be considered.
