Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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.
