Auto-Injector for Intramuscular Injection of Epinephrine
The EpiPen® and Epipen® Jr auto-injectors contain 2 mL epinephrine injection for emergency intramuscular use. Each EpiPen® auto-injector delivers a single dose of 0.3 mg epinephrine from epinephrine injection, USP, 1:1000 (0.3 mL) in a sterile solution.
Epinephrine is indicated in the emergency treatment of allergic reactions (anaphylaxis) to insect stings or bites, foods, drugs and other allergens as well as idiopathic or exercise-induced anaphylaxis. The EpiPen® and EpiPen® Jr auto-injectors are intended for immediate self-administration by a person with a history of an anaphylactic reaction. Such reactions may occur within minutes after exposure and consist of flushing, apprehension, syncope, tachycardia, thready or unobtainable pulse associated with a fall in blood pressure, convulsions, vomiting, diarrhea and abdominal cramps, involuntary voiding, wheezing, dyspnea due to laryngeal spasm, pruritis, rashes, uticaria or angioedema. The EpiPen® and EpiPen® Jr are designed as emergency supportive therapy only and are not a replacement or substitute for immediate medical or hospital care.

OBJECTIVE: The objective of this study was to evaluate the effect of intravenous lidocaine combined with amitriptyline on pain relief and plasma serotonin, norepinephrine, and dopamine levels... CONCLUSIONS: Combined administration of 240 mg intravenous lidocaine (once a week) and 25 mg amitriptyline for 4 weeks did not modify pain intensity or plasma serotonin, norepinephrine, or dopamine concentrations in fibromyalgia patients.
Anesthetic efficacy of 4% Articaine with 1:100,000 epinephrine versus 4% articaine with 1:200,000 epinephrine as a primary buccal infiltration in the mandibular first molar. [2011.04]
INTRODUCTION: No study has compared 4% articaine with 1:100,000 epinephrine with 4% articaine with 1:200,000 epinephrine in a mandibular buccal infiltration of the first molar. The authors conducted a prospective, randomized, double-blind, crossover study comparing the degree of pulpal anesthesia obtained with 4% articaine with 1:100,000 epinephrine and 4% articaine with 1:200,000 epinephrine as a primary infiltration in the mandibular first molar... CONCLUSIONS: The anesthetic efficacy of 4% articaine with 1:200,000 epinephrine is comparable to 4% articaine with 1:100,000 epinephrine in a primary mandibular buccal infiltration of the first molar.

Clinical Trials Related to Epipen (Epinephrine Injection)
Vasopressin and Epinephrine Versus Epinephrine Alone in Cardiac Arrest [Completed]
Recent studies have suggested that arginine-vasopressin could be more effective in the
treatment of cardiac arrests. The last published study did not outline obvious improvements
in the prognosis of all cardiac arrests but pointed out a possible increased survival rate
when arginine-vasopressin is associated with epinephrine. The aim of this study is to compare
the efficacy of two successive injections of epinephrine (1 mg) with two successive
injections of epinephrine associated with arginine-vasopressin (40 UI) in out-of-hospital
cardiac arrests occurring in adult patients. The primary endpoint is the survival rate at
hospital admission. The inclusion period lasts 18 months and 2416 patients are planned to be

Epinephrine Inhalation Aerosol USP, a HFA-MDI Study for Assessment of Pharmacokinetics [Recruiting]
This study examines the pharmacokinetic profile of Armstrong's proposed Epinephrine
Inhalation Aerosol USP, an HFA-MDI (E004), using a stable isotope deuterium-labeled
epinephrine (epinephrine-d3) to differentiate the administered drug from the endogenous
epinephrine, in healthy male and female adult volunteers. The current study is designed for
a more thorough evaluation of the E004 Pharmacokinetics. Safety of E004 will also be
evaluated, under augmented dose conditions.
Epinephrine Inhalation Aerosol USP: For Evaluation Of Efficacy And Safety In Asthma Patients [Recruiting]
This clinical study evaluates the 12-week efficacy and safety of Epinephrine HFA Inhalation

Test Predicting Adrenal Insufficiency in Volunteers Under Prednisone Treatment [Recruiting]
Suppression of the adrenal function is a common, potentially dangerous and unpredictable
