levorphanol

Levorphanol, also known by the brand name Levo-Dromoran, is a synthetic opioid analgesic. It is a morphinan derivative, structurally related to other opioids like dextromethorphan and codeine. Levorphanol is primarily used for the management of moderate to severe pain. It functions by binding to opioid receptors in the central nervous system, altering the body's perception of pain.

The drug is available in oral and injectable formulations. Its onset of action is relatively quick, and its duration of effect can be prolonged. Levorphanol is considered a potent opioid, with analgesic properties that are roughly twice that of morphine. It is prescribed for chronic pain conditions that require continuous, around-the-clock opioid treatment, as well as for acute pain.

Like other opioids, levorphanol carries a risk of side effects, including respiratory depression, constipation, nausea, vomiting, and drowsiness. Dependence and addiction are also significant concerns with its use. Due to its potency and potential for abuse, levorphanol is a controlled substance and its use is carefully monitored by healthcare professionals. It is not typically recommended for mild or intermittent pain.
