  <description>Levorphanol is an exogenous organic compound with the formula C17H23NO and an average molecular weight of 257.37 g/mol. It exists as a solid at room temperature. Levorphanol belongs to the morphinans, a class of alkaloids and derivatives within the organic compounds.

The compound is associated with 21 recorded sources. These include electrical and electronic equipment such as amplifiers, antennas, communication cables or conductors, contacts, and cores yokes or armatures. It is also found in building and construction materials, specifically ceilings and tents or canopies. In the category of food, food processing and cookware, it is linked to the treatment of hops and the preparation of vinegar and wort. Additionally, it is found in household cleaning and consumer products, including pipe accessories, other smoking requisites, and non electric simulated smoking devices.

Levorphanol acts on three recorded protein targets: the delta-type opioid receptor (OPRD1), the kappa-type opioid receptor (OPRK1), and the mu-type opioid receptor (OPRM1). 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.</description>

  <health-effects>Medical problems can include congested lungs, liver disease, tetanus, infection of the heart valves, skin abscesses, anemia and pneumonia. Death can occur from overdose.</health-effects>
  <symptoms>Signs of overdose include nausea, emesis, dizziness, respiratory depression, hypotension, urinary retention, cardiac arrhythmias, allergic reactions, skin rash, and uticaria.</symptoms>
  <treatment>The specific treatment of suspected levorphanol tartrate overdosage is immediate establishment of an adequate airway and ventilation, followed (if necessary) by intravenous naloxone. The respiratory and cardiac status of the patient should be continuously monitored and appropriate supportive measures instituted, such as oxygen, intravenous fluids and/or vasopressors, if required. Physicians are reminded that the duration of levorphanol action far exceeds the duration of action of naloxone, and repeated dosing with naloxone may be required. Naloxone should be administered cautiously to persons known or suspected to be physically dependent on Levorphanol. In such cases an abrupt and complete reversal of opioid effects may precipitate an acute abstinence syndrome. If necessary to administer naloxone to the physically dependent patient, the antagonist should be administered with extreme care and by titration with smaller than usual doses of the antagonist.
