Drug: Midazolam

Interventions

Midazolam DRUG

The study drug was administered IM into the anterior thigh using the preloaded autoinjector. The autoinjectors were preloaded with midazolam 5 mg or 10 mg with a total volume of 1 or 2 mL. Healthy subjects were assigned to one of six target dosage groups (0.10, 0.18, 0.25, 0.33, 0.40, 0.49 mg/kg) and, based on their weight, received the necessary combination of fixed 5 or 10 mg doses to provide the assigned target dose.
