Can you list every analogue of Dextromethorphan?

Dextromethorphan (DXM) is a cough suppressant commonly found in over-the-counter medications. As an analogue, it may refer to various compounds that are chemically related or share similar pharmacological properties. Some notable analogues and related compounds include: 1. **Dextrophan** - An active metabolite of DXM that possesses some cough suppressant properties. 2. **Dextrorphan** - Another active metabolite of DXM, primarily noted for its NMDA receptor antagonist activity. 3. **3-Methoxymorphinan** - A structural analogue that has some similar effects. 4. **Bromodextromethorphan** - An analogue that explores variations in potency and effects. 5. **Doxylamine** - While not a direct analogue, it shares some antihistaminic properties with applications in cough and cold formulations. 6. **Carbetapentane** - A cough suppressant that is sometimes used in combination with antihistamines. It's important to note that while these compounds can be considered analogues or have similarities in action, they may differ significantly in their effects, safety profiles, and legal status. Additionally, the research surrounding some of these compounds may not be as extensive as that of DXM. For any specific medical or therapeutic use, always consult a healthcare professional.
