How Levorphanol works

Like other mu-agonist opioids it is believed to act at receptors in the periventricular and periaqueductal gray matter in both the brain and spinal cord to alter the transmission and perception of pain.

Toxicity

LD50=150 mg/kg (orally in rats). Signs of overdose include nausea, emesis, dizziness, respiratory depression, hypotension, urinary retention, cardiac arrhythmias, allergic reactions, skin rash, and uticaria.

Food Interaction

  • Avoid alcohol.
  • Take with or without food. Food does not significantly affect absorption.

Levorphanol Alcohol interaction

[Moderate] GENERALLY AVOID:

Ethanol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics.

Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills.

In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

Concomitant use of opioid analgesics with ethanol should be avoided.
