Aromarone - General Information

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


Pharmacology of Aromarone

Aromarone 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. Aromarone is similar to morphine in its actions, however it is up to 8 times more potent than morphine. Aromarone 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.

Aromarone Interactions

Interactions with Other CNS Agents: Concurrent use of Levo-Dromoran with all central nervous system depressants (eg, alcohol, sedatives, hypnotics, other opioids, general anesthetics, barbiturates, tricyclic antidepressants, phenothiazines, tranquilizers, skeletal muscle relaxants and antihistamines) may result in additive central nervous system depressant effects. Respiratory depression, hypotension, and profound sedation or coma may occur. When such combined therapy is contemplated, the dose of one or both agents should be reduced. Although no interaction between MAO inhibitors and Levo-Dromoran has been observed, it is not recommended for use with MAO inhibitors.

Most cases of serious or fatal adverse events involving Levo-Dromoran reported to the manufacturer or the FDA have involved either the administration of large initial doses or too frequent doses of the drug to nonopioid tolerant patients, or the simultaneous administration of levorphanol with other drugs affecting respiration. The initial dose of levorphanol should be reduced by approximately 50% or more when it is given to patients along with another drug affecting respiration.

Interactions with Mixed Agonist/Antagonist Opioid Analgesics:   Agonist/antagonist analgesics (eg, pentazocine, nalbuphine, butorphanol, dezocine and buprenorphine) should NOT be administered to a patient who has received or is receiving a course of therapy with a pure agonist opioid analgesic such as Levo-Dromoran. In opioid-dependent patients, mixed agonist/antagonist analgesics may precipitate withdrawal symptoms.


Aromarone Contraindications

Levo-Dromoran is contraindicated in patients hypersensitive to levorphanol tartrate.


Additional information about Aromarone

Aromarone Indication: For the management of moderate to severe pain or as a preoperative medication where an opioid analgesic is appropriate
Mechanism Of Action: 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.
Drug Interactions: Cimetidine Cimetidine increases the effect of the narcotic
Naltrexone Naltrexone may precipitate a withdrawal syndrome in opioid-dependent individual
Food Interactions: Take without regard to meals. Avoid alcohol.
