چکیده

Levorphanol, termed “the forgotten opioid,” is a potent opioid analgesic available for the treatment of moderate to severe pain. It was first approved in 1953, and it has a wide range of ascending and descending pain pathway receptor-mediated pharmacological activities, including mu, delta, and kappa (kappa 1 and 3) opioid agonism; N-methyl-D-aspartate (NMDA) antagonism; and reuptake inhibition of both norepinephrine and serotonin.1

Levorphanol use: past, present and future.

Levorphanol is a potent opioid analgesic that was first approved for use in the United States in 1953. Levorphanol is approved for use in moderate to severe pain where an opioid analgesic is appropriate. Levorphanol has a wide range of activities including mu opioid agonism, delta agonism, kappa1 and kappa3 receptor agonism, N-methyl-d-aspartate receptor antagonism and reuptake inhibition of bo...

Clinical pharmacology of opioids for pain.

The pharmacological effects of the opioid analgesics are derived from their complex interactions with three opioid receptor types (mu, delta, and kappa; morphine is an agonist at the mu opioid receptor). These receptors are found in the periphery, at presynaptic and postsynaptic sites in the spinal cord dorsal horn, and in the brain stem, thalamus, and cortex, in what constitutes the ascending ...

Levorphanol: Revisiting an Underutilized Analgesic

Levorphanol (levo-3-hydroxy-N-methylmorphinan) is a step 3 opioid first developed in the 1940s as an alternative to morphine. Levorphanol belongs to the morphinan opioid series. Levorphanol has greater potency than morphine and is a potent N-methyl-d aspartate (NMDA) antagonist. Levorphanol interferes with the uptake of norepinephrine and serotonin, which makes it potentially useful for neuropa...

Comparison of the effects of dextromethorphan, dextrorphan, and levorphanol on the hypothalamo-pituitary-adrenal axis.

Dextromethorphan is a weak noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist. It is metabolized in vivo to dextrorphan, a more potent noncompetitive NMDA antagonist that is the dextrorotatory enantiomer of the opioid agonist levorphanol. The present study characterized the effects of the acute administration of dextromethorphan, dextrorphan, and levorphanol on the hypothalamo-pitui...

Mu opioid agonists potentiate amphetamine- and cocaine-induced rotational behavior in the rat.

Opioids modulate brain dopaminergic function in various experimental paradigms. This study used the rotational model of behavior in rats with unilateral 6-hydroxydopamine-induced lesions of the nigrostriatal pathway to investigate this interaction. Doses of two presynaptically acting dopaminergic drugs, amphetamine and cocaine, were coadministered with several doses of the mu opioid agonist, mo...
