Antiepileptic Drug Use Patterns in Suspect Epileptic Dogs Among Neurology and Emergency Specialists.

This study used a cross-sectional survey designed to inquire about antiepileptic drug (AED) use in newly diagnosed idiopathic epileptic dogs among board-certified emergency and neurology specialists. Results were obtained from 300 completed surveys by 128 board-certified neurologists and 172 board-certified emergency and critical care (ECC) specialists. Case volume was slightly different between groups, with 36% of neurologists and 18% of ECC specialists managing >50 cases of first-time canine seizure patients yearly. The initial AED of choice was similar between the groups, with 66% of neurologists and 64% of ECC specialists using phenobarbital and 16% of neurologists and 26% of ECC specialists using levetiracetam. Although most respondents gave a loading dose of phenobarbital, roughly one-fourth of neurologists did not load the drug versus 6% of ECC specialists. The total loading dose was similar between respondents (16 mg/kg) but varied in administration protocol. Approximately half of neurologists and nearly two-thirds of ECC specialists gave a higher initial dose of levetiracetam than recommended. Almost all the respondents who gave a higher initial dose of levetiracetam used 60 mg/kg IV once. Understanding the common practices in AED use may promote future discussions regarding best practices in the management of canine idiopathic epilepsy.
