Conditions
Brief summary
Fentanyl is a strong analgesic (painkiller) with similar effects to morphine. Recently a fentanyl wafer has been developed that dissolves quickly when placed under the tongue. This has advantages of quick absorption, rapid onset of action and would be suitable for patients who cannot swallow tablets, or are phobic to needles. The present study compares the pharmacokinetics and bioavailability of the sublingual wafer fetanyl formulation with the currently registered IV forumulation.
Interventions
Sublingual Fetanyl Wafer.
In the present cross-over trial, healthy participants will receive a single dose of both sublingual wafer (100mcg) and IV fentanyl (100mcg), one treatment per period, in randomised order. A 5 day wash-out period is applicable between Sublingual/IV treatment arms.
In both arms dosing is subject to participants' passing a 50mg pre dose-day (Day -1) naltrexone challenge, such that pre-dose naltrexone may be administered to counter-act the effects of fetanyl dosing.

No abnormal finding of clinical relevance at the Screening evaluation.
Exclusion criteria

Evidence of clinically relevant oral, cardiovascular, hematological, gastrointestinal, hepatic, renal, endocrine, pulmonary, neurologic, psychiatric, or skin disorder, or history of hypertension or heart disease. 9.Acute therapy for a serious infection within 30 days of study entry. 10.Currently suffers from clinically significant systemic allergic disease or has a history of significant drug allergies including a history of: anaphylactic reaction; allergic reaction due to any drug which leads to significant morbidity (e.g. penicillin); neuro malignant syndrome or malignant hyperthermia. 11.Have participated in a clinical trial or have received an experimental therapy within 30 days or 10 half-lives of the drug, whichever is the longer, prior to dosing. 12.Blood donation of greater than 400 mL within 8 weeks before the first dose administration. 13. Males who regularly drink more than four (4) units of alcohol daily (1 unit = 300 mL beer, 1 glass wine, 1 measure spirit) or those who may have difficulty abstaining from alcohol during the 48 hours prior to dose administration and until completion of blood sampling. 14.Females who regularly drink more than two (2) units of alcohol daily (1 unit = 300 mL beer, 1 glass wine, 1 measure spirit) or those who may have difficulty abstaining from alcohol during the 48 hours prior to dose administration and until completion of blood sampling. 15.
