RICHMOND, Va., July 10, 2014 /PRNewswire/ -- Kaleo, a privately-held pharmaceutical company headquartered in Richmond, Virginia, today announced the United States (U.S.) commercial availability of EVZIO for the emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system depression. EVZIO is not a substitute for emergency medical care. EVZIO, approved by the U.S. Food and Drug Administration (FDA) on April 3, 2014, is the first and only naloxone product labeled for immediate administration by family members or caregivers.1
"Opioid overdose is a significant and growing public health concern in America and until now, there have been limited options available for the rapid administration of this potentially life-saving drug in non-healthcare settings," said Spencer Williamson, CEO of kaleo. "We are pleased to be able to make EVZIO available soon after receiving approval by the FDA."
EVZIO is now available in the United States by prescription. EVZIO should be administered as quickly as possible when an opioid overdose is suspected because prolonged respiratory depression may result in damage to the central nervous system or death. Because people experiencing an opioid overdose generally lose consciousness, in most cases, family members or caregivers will likely be the ones who administer EVZIO. EVZIO uses voice and visual cues to assist in guiding a user through the injection process. After administering EVZIO, emergency medical care should be immediately sought.
"EVZIO is the first and only FDA approved naloxone auto-injector specifically designed to be used by individuals without medical training," said Evan Edwards, kaleo's Vice President of Product Development. "Additionally, using kaleo's comprehensive human factors engineering process, EVZIO was designed and validated for use by family members and caregivers."
To better serve patients, kaleo offers patient assistance and savings programs through kaleo Cares. For more information about kaleo Cares, please visit www.kaleopharma.com/who-we-are/kaleo-cares/
EVZIO is a pre-filled, single-use, hand-held auto-injector that works by temporarily blocking the effect of an opioid, potentially reversing the life-threatening respiratory depression and allowing the recipient to breathe more regularly. Each EVZIO delivers a single 0.4 mg dose of naloxone HCl injection. Since the duration of action of most opioids may exceed that of naloxone, seek immediate emergency medical assistance, keep the patient under continued surveillance, and administer repeated doses of EVZIO as necessary.

Important Safety Information
EVZIO is contraindicated in patients known to be hypersensitive to naloxone hydrochloride or to any of the ingredients in EVZIO.
The following warnings and precautions should be taken when administering EVZIO:
- Due to the duration of action, keep the patient under continued surveillance and repeated doses of naloxone should be administered, as necessary, while awaiting emergency medical assistance.
- Additional supportive and/or resuscitative measures may be helpful while awaiting emergency medical assistance.
- Reversal of respiratory depression by partial agonists or mixed agonists/antagonists, such as buprenorphine and pentazocine, may be incomplete.
- Use in patients who are opioid dependent may precipitate acute abstinence syndrome.
- Patients with pre-existing cardiac disease or patients who have received medications with potential adverse cardiovascular effects should be monitored in an appropriate healthcare setting.
- In neonates, opioid withdrawal may be life-threatening if not recognized and properly treated.
The following adverse reactions have been identified during use of naloxone hydrochloride in the postoperative setting: hypotension, hypertension, ventricular tachycardia and fibrillation, dyspnea, pulmonary edema, and cardiac arrest. Death, coma, and encephalopathy have been reported as sequelae of these events. Excessive doses of naloxone hydrochloride in postoperative patients have resulted in significant reversal of analgesia and have caused agitation.
Abrupt reversal of opioid effects in persons who were physically dependent on opioids has precipitated signs and symptoms of opioid withdrawal including: body aches, fever, sweating, runny nose, sneezing, piloerection, yawning, weakness, shivering or trembling, nervousness, restlessness or irritability, diarrhea, nausea or vomiting, abdominal cramps, increased blood pressure, and tachycardia. In the neonate, opioid withdrawal signs and symptoms also included: convulsions, excessive crying, and hyperactive reflexes.

About Opioid Overdose
According to the Institute of Medicine, chronic pain affects about 100 million American adults more than the total affected by heart disease, cancer and diabetes combined.2
Opioids are used to treat pain associated with a variety of acute and chronic medical conditions. Nearly 17,000 Americans die each year from prescription opioid overdose, and accidental drug poisoning has surpassed automobile collisions as the leading cause of accidental death in the U.S., driven largely by prescription opioids.3,4 Opioid overdose can cause a person's breathing to severely slow down and even stop. Opioid medications have a relatively narrow therapeutic window, meaning that even small changes such as a single extra dose or the addition of a small amount of alcohol can cause a potentially fatal overdose.5
Some risk factors for overdose include: history of substance abuse or dependence, taking high doses of opioids, no previous history of taking opioids,6 a recent dosage increase, extended-release or long-acting opioids,7 taking certain antidepressants like monoamine oxidase inhibitors (MAOIs) or certain drugs for anxiety, and a history of respiratory conditions such as asthma, COPD and sleep apnea.6 In addition, children living with someone consuming prescription opioids have been shown to be at increased risk.8
Signs and symptoms of opioid overdose include very slow or absent breathing, loss of consciousness, extremely small pupils, and slow heartbeat.2
