The word "Levorine" is a term that may be familiar to those in the pharmaceutical industry. Pronounced /liːvəraɪn/, it is spelled in accordance with the International Phonetic Alphabet (IPA). The first three letters, "lev," can be associated with the prefix "lev-" which means left or in this case, the left-handed form of a molecule. The suffix "-orine" is likely derived from the term "amine" which denotes a type of organic compound that contains a nitrogen atom. Thus, "Levorine" refers to a specific left-handed form of an amine compound.
Levorine is a noun that refers to a synthetic analgesic drug, also known as levorphanol tartrate. It falls under the opioid class of medications and is primarily used for the relief of severe, chronic pain that is unresponsive to other non-opioid medications. Levorine acts on the central nervous system to modify pain sensation by binding to opioid receptors in the brain and spinal cord. It produces analgesic effects by interrupting the transmission of pain signals and altering the perception of pain.
Levorine is typically administered orally in tablet or liquid form, although it may also be given via intramuscular or intravenous injection when necessary. The drug is subject to prescription and controlled substance regulations due to its potential for misuse, dependence, and addiction. Therefore, it is typically prescribed under close medical supervision, with dosage and duration tailored to individual patient needs and regularly monitored to prevent abuse.
While levorine is primarily valued for its anodyne properties, it can also induce side effects, including drowsiness, dizziness, lightheadedness, gastrointestinal disturbances, respiratory depression, and constipation. Patients taking levorine should be aware of these potential adverse effects and exercise caution when operating heavy machinery or driving a vehicle. Additionally, levorine should not be used concomitantly with alcohol or other central nervous system depressants, as it may enhance their sedative effects and pose a significant risk of respiratory depression or fatal overdose.
