Benzodiazepines, including diazepam and midazolam, are the mainstay of treatment for seizure emergencies, including acute repetitive seizures. Nonparenteral dosage forms are used when parenteral (intravenous or intramuscular) dosing is not feasible. Currently available nonparenteral dosage forms have limitations in terms of usability, patient and caregiver acceptance, speed of action, and portability. Diazepam buccal film (DBF) is a compact, easily administered diazepam formulation. When placed onto the buccal mucosa inside the cheek, DBF adheres firmly and then rapidly dissolves, delivering diazepam transbucally and via the gastric route. In fasted healthy male volunteers, plasma levels were achieved rapidly after DBF placement in a linear dose-proportional fashion. Bioavailability in adult patients with epilepsy was not significantly different when DBF was applied interictally or periictally (within 5 min of a seizure). Diazepam buccal film was successfully placed and generally used without difficulty, even without patient cooperation immediately after a seizure. In a crossover comparative study with diazepam rectal gel (Diastat®) in adult patients with epilepsy, DBF performed equivalently to the rectal gel, but peak exposures were less variable. Diazepam buccal film is a convenient alternative for out-of-hospital treatment of seizure exacerbations. Proceedings of the 7th London-Innsbruck Colloquium on Status Epilepticus and Acute Seizures.
