Further study details as provided by Pakit Vichyanond, MD, Siriraj Hospital:

Primary Outcome Measures:
  • Composite of Pharmacokinetics of epinephrine [ Time Frame: predose, 5 , 10, 15, 20, 30, 45, 60, 90, 120, 180 minutes post-dose ]
    Cmax, Area Under Curve, Tmax of epinephrine compare between 0.3 mg intramuscular and 5 mg intranasal route

Secondary Outcome Measures:
  • Numbers of participants with adverse events as a measure of safety and tolerability [ Time Frame: 1 year ]
    Any side effects from such administration such as bad smelling, sorethroat.

Estimated Enrollment: 12
Study Start Date: July 2010
Study Completion Date: September 2011
Primary Completion Date: August 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: epinephrine IN, epinephrine IM, saline IN
  1. Intranasal saline
  2. Intramuscular epinephrine
  3. Intranasal epinephrine
Drug: Epinephrine
  1. Intranasal epinephrine 5 mg /spray
  2. Intramuscular epinephrine 0.3 mg
  3. Intranasal saline spray
Other Name: adrenaline

Detailed Description:
Patients are reluctant to use Epipen® on emergency basis, perhaps because of improperly training, hesitancy and fear of needle. Other route of administration of epinephrine (EPI) may be more benefit such as intranasal route.
