Study Start Date:	July 2006
Study Completion Date:	December 2006

Arms	Assigned Interventions
No Intervention: 1	Drug: Midazolam 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.

Drug: Midazolam

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.

Detailed Description:

The investigational drug product being evaluated in this study is the Midazolam Autoinjector. This system is composed of an autoinjector filled with the drug product midazolam EP. The study drug is administered IM into the anterior thigh using the preloaded autoinjector. This method of administration was selected as it is the method that will be used in later clinical trials and for the marketed product. The autoinjectors were preloaded with midazolam 5 mg or 10 mg with a total volume of 1 or 2 mL. Healthy subjects are 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.
