EPIPEN SUMMARY
EPIPEN®
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.

Effect of intravenous lidocaine associated with amitriptyline on pain relief and plasma serotonin, norepinephrine, and dopamine concentrations in fibromyalgia. [2011.05]
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
enrolled.
Changes in Adrenal Hormones During Adrenal Radiofrequency Ablation [Recruiting]
Trial of Vasopressin and Epinephrine to Epinephrine Only for In-Hospital Pediatric Cardiopulmonary Resuscitation [Recruiting]
Cardiac arrest has a very poor prognosis, especially with prolonged efforts at
resuscitation, and unfortunately, survivors are often severely neurologically impaired. CPA
in children is often the result of a prolonged illness rather than a sudden, primary cardiac
event as is frequent in adults. This necessitates that resuscitation research must be
conducted separately for pediatric and adult patients. Authorities currently endorse the
use of epinephrine for restoring spontaneous circulation based on its ability to maintain
diastolic blood pressure and subsequent blood flow to the heart during resuscitation.
However, human studies have shown no clear survival benefit of epinephrine and have
elucidated concerning adverse effects. Recently, both the European Resuscitation Council and
the American Heart Association have recognized the use of vasopressin as a promising
vasoconstrictor and an alternative or adjunct to epinephrine in the resuscitation of adults.
Vasopressin causes profound vasoconstriction without the adverse effects of epinephrine and
is associated with improved blood flow to the heart and brain. This increased cerebral
blood flow has been associated with better neurologic outcome in animal studies. In light of
compelling animal and human studies of combined vasopressin and epinephrine, pediatric
trials are indicated for vasopressin usage in pediatric CPR. This study will evaluate the
addition of the administration of vasopressin to standard advanced CPR therapy (epinephrine
alone) for pediatric patients that experience in-intensive care unit CPA to assess for
improved time to return of spontaneous circulation (ROSC), survival to 24 hours, survival to
hospital discharge, and neurologic outcome. When a patient experiences a CPA, standard
Pediatric Advanced Life Saving (PALS) protocols as endorsed by the American Heart
Association will be initiated. This will include receiving epinephrine as the first
vasopressor medication. Patients will then be randomized to receive vasopressin (treatment
group) or epinephrine (control group) as the second vasopressor medication, if needed. If
more then two doses of vasopressor medication is required in either group, epinephrine will
be administered according to the PALS algorithm until the end of the event. All CPA events
meeting inclusion criteria will be entered into the National Registry of Cardiopulmonary
Resuscitation (NRCPR) Database, which tracts all CPA events at Children's Medical Center
Dallas. Prior to commencement of the RCT, a pilot trial of 10 patients will be completed to
assess preliminary safety, feasibility, and effectiveness of combination
epinephrine-vasopressin for pediatric in-intensive care unit CPA refractory to initial
epinephrine dosing. All pilot patients will receive vasopressin as the second vasopressor
medication.
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

a more thorough evaluation of the E004 Pharmacokinetics. Safety of E004 will also be
evaluated, under augmented dose conditions.
