Levorfanolo Uses, Dosage, Side Effects, Food Interaction and all others data.

A narcotic analgesic that may be habit-forming. It is nearly as effective orally as by injection.

Levorfanolo is a potent synthetic opioid analgesic indicated for the management of moderate to severe pain or as a preoperative medication where an opioid analgesic is appropriate. Levorfanolo is similar to morphine in its actions, however it is up to 8 times more potent than morphine. Levorfanolo produces a degree of respiratory depression similar to that produced by morphine at equianalgesic doses, and like many mu-opioid drugs, levorphanol produces euphoria or has a positive effect on mood in many individuals.

How Levorfanolo 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.

Levorfanolo 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.
