ABSTRACT
The neurosteroid allopregnanolone (ALLO) is under investigation as a treatment for benzodiazepine-refractory status epilepticus (SE). Here, we assess the cardiopulmonary safety of intravenous ALLO by itself and after a clinically recommended dose of midazolam (MDZ) in two healthy adult beagles. Each dog received ALLO (1 mg/kg, IV), and after a washout period of 2 weeks, each dog was dosed with MDZ (0.2 mg/kg, IV) followed 10 minutes later by ALLO. Behavioral state, vital signs, arterial blood gases, blood chemistries, and plasma ALLO concentrations were monitored for up to 6 hours after dosing. The dogs appeared sleepy but were fully responsive after both treatments. No depression of mean arterial pressure or respiratory rate was noted. Blood gas measurements failed to show evidence of drug-induced acute respiratory acidosis. Estimated maximum plasma ALLO concentrations were in the range of 1500 to 3000 ng/ml. The results indicate that intravenous ALLO can be used safely to treat benzodiazepine-refractory SE, even when administered shortly after a benzodiazepine.
