Brief summary

This is a first in human study for the DMTS. This study is evaluating a different formulation of dexmedetomidine by determining the bioavailability and pharmacokinetics of dexmedetomidine following a single 3-day application of the DMTS compared with a 24 hour IV infusion of Precedex and assessing the safety and tolerability. This is an open-label, randomized, two-period, cross-over study.

Interventions

Dexmedetomidine Transdermal System (DMTS): The DMTS is a patch that contains 7.32 mg of dexemedetomidine. Based on the non-clinical data, the expected delivered dose is 1.44 mg at an average rate of 20 mcg/h over three days. The patch will be checked for integrity at 6, 12, 24, 48 hours after application, and immediately prior to patch removal. There will be a minimum washout period of 2 days.

Exclusion criteria

1. A history or presence of drug or alcohol dependence (excluding caffeine), including subjects who have ever been in a drug rehabilitation program based on medical history of the past 10 years. 2. Clinically significant abnormalities as judged by the investigator or designee and determined by physical examination (PE), medical history, 12-lead electrocardiogram (ECG), vital signs, laboratory values, including serum kidney and liver function tests. 3. Presence of postural hypotension (determined through examination by the investigator or designee), or recent history of severe dizziness or fainting due to postural hypotension on standing. 4. Subjects with a history of seizures, asthma, or obstructive pulmonary disease. 5. Presence or history of any of the following disorders that are deemed clinically significant by the investigator or designee: a psychiatric disorder (including suicidal ideation and behavior), organic brain disorder, or seizure disorder. 6.
