- Classes: Opioid Reversal Agents
Description
Opioid antagonist; derivative of oxymorphone
Used for reversal of opioid-induced respiratory and CNS depression
Auto-injector and nasal formulations available to treat or prevent an overdose outside of health care setting
Indications
Indicated for the complete or partial reversal of opioid depression (including respiratory depression) induced by natural and synthetic opioids
Indicated for emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system (CNS) depression
Intended for immediate use as emergency therapy in settings where opioids may be present
For reversal of opiate agonist-induced respiratory depression.
Contraindications
Hypersensitivity
Adverse Effects
Withdrawal reaction precipitated
Abrupt reversal of narcotic depression may result in nausea, vomiting, sweating, tachycardia, increased blood pressure and tremulousness
Cardiac arrest
Ventricular fibrillation
Dyspnea
Pulmonary edema
Abdominal cramps
Diarrhea

Warnings
Caution in patients with cardiovascular disease or patients receiving medications with potential adverse cardiovascular effects
Caution in patients with history of seizures; avoid use in treatment of meperidine-induced seizures
Recurrence of respiratory depression may occur if opioid involved is long-acting or a partial agonist (eg, methadone, buprenorphine); observe patients until there is no further risk of recurrent respiratory or CNS depression
Avoid excessive dosages after use of opioids in surgery; abrupt postoperative reversal may unmask pain and may cause nausea, vomiting, sweating, seizures, hypertension, and tachycardia; other cardiovascular events, including pulmonary edema and arrhythmias may occur
