Methorphan

Methorphan is a type of opioid and antitussive drug that is used in many over-the-counter cough and cold medications. It is available in two isomeric forms, dextromethorphan (DXM) and levomethorphan (Levo), each of which has different effects and uses.

Pharmacology

Methorphan comes in two forms: dextromethorphan and levomethorphan. Dextromethorphan is a noncompetitive NMDA receptor antagonist and also acts as a serotonin reuptake inhibitor. Levomethorphan is an opioid analgesic.

Medical uses

Methorphan is primarily used as a cough suppressant in many over-the-counter cold and cough medicines. It is also used for pain relief in certain medical situations.

Side effects

Like all medications, methorphan can cause side effects. These can include dizziness, nausea, and in some cases, hallucinations. It is important to use this medication as directed by a healthcare professional to minimize the risk of side effects.
