Dextromethorphan's effects have been divided into four plateaus. [14] The first plateau (1.5 to 2.5 mg per kg body weight) is described as having euphoria, auditory changes, mild stimulation, and change in perception of gravity. The second plateau (2.5 to 7.5 mg/kg) causes intense euphoria, vivid imagination, and closed-eye hallucinations.
Dextromethorphan, sold under the brand name Robitussin among others, is a cough suppressant used in many cough and cold medicines. [6] In 2022, the US Food and Drug Administration (FDA) approved the combination dextromethorphan/bupropion to serve as a rapid-acting antidepressant in people with major depressive disorder.
Antitussives, or cough suppressants, are substances which suppress the coughing itself. Examples are dextromethorphan, benzonatate, codeine, hydrocodone, pholcodine, noscapine, cloperastine, and butamirate. Antihistamines, for allergic rhinitis, may produce mild sedation and reduce other associated symptoms, like a runny nose and watery eyes.

Dextromethorphan/bupropion has less activity as an NMDA receptor antagonist than dextromethorphan alone. [11] This is because bupropion is a potent CYP2D6 inhibitor and prevents the bioactivation of dextromethorphan into dextrorphan , a much more potent NMDA receptor antagonist and weaker serotonin reuptake inhibitor than dextromethorphan ...
