Outcomes
Primary outcome [1] 331847 0
To determine the pharmacokinetics effects of different dosages of dexmedetomidine wafers administered via sublingual route vs. intravenous dexmedetomidine. Standard non-compartmental analysis methods will be used to obtain PK variables for dexmedetomidine such as Cmax, AUCinf, CL, Tmax, Cmax, Vz, and t1/2.
Timepoint [1] 331847 0
Pharmacokinetic blood samples will be collected pre-dose and at 5, 10, 15, 20, 30, 40, 50 mins and 1, 1.5, 2, 3, 4, 6, 8, 12 and 24 hours post dose.
Secondary outcome [1] 411388 0
To determine safety and tolerability of dexmedetomidine wafers administered via sublingual route by monitoring physical status through vital signs (blood pressure[ [assessed by sphygmomanometer], pulse [measured by pulse oximeter], respirations [measured by 60 second manual count], and temperature), physical exams, safety laboratory testing (hematology and chemistry) and level of sedation (using the Richmond Agitation Sedation Scale).
Timepoint [1] 411388 0
Vital signs will be measured pre-dose, at 30 minutes, and at 1.00, 1.50, 2.00, 2.50, 3.00, 4.00, 6.00, 8.00, 12.00 and 24.00 hours post-dose during each period
Physical exams will be conducted at screening, check-in, and 24 hours post-dose Treatment D.
Safety laboratory testing will be completed at screening, pre-dose and 24 hours post-dose Treatment D.
Sedation scores will be measured pre-dose and at 0.50, 1.00, 1.50, 2.00, 2.50, 3.00, 4.00, 5.00, 6.00, 8.00, 12.00, and 24.00 hours post-dose during each period.
Secondary outcome [2] 411475 0
Safety and tolerability will be measured by adverse events reported by and observed by staff and will be reported using standard MedDRA terminology. Investigator will determine relationship of adverse events to study medication. Known adverse effects associated with the use of dexmedetomidine include hypo or hypertension and bradycardia.
Timepoint [2] 411475 0
Adverse events will be collected from time of initial dose of Treatment A through the follow-up phone call. The follow-up phone call will occur 3 days (+/- 1 day) post discharge from the inpatient portion of the study.

Summary
Brief summary
This is an open-label, four-way crossover, fasted pharmacokinetic study in healthy volunteers.
The screening visit will include a physical exam, vital signs collection, an electrocardiogram, safety laboratory sampling and urinalysis to determine suitability for inclusion into the study.
Qualified study participants will be admitted the evening prior (Day -1) to scheduled dosing. Each participant will receive a single dose of study medication per dosing day. There will be a minimum washout of 44 hours between doses.
Participants will remain inpatient for the entire dosing/washout period and will be discharged 24 hours after Treatment D.
