Ketamine’s Mechanism of Action: NMDA Receptors and Beyond
Ketamine’s analgesic effects are largely attributed to its interaction with NMDA receptors, which play a pivotal role in pain perception. By antagonizing these receptors, ketamine disrupts the transmission of pain signals, providing swift relief. But ketamine’s influence goes beyond NMDA receptors. It modulates glutamatergic signaling, exerting an inhibitory effect on pain pathways. Moreover, ketamine’s impact on neuroplasticity—altering the brain’s structure and function—offers a potential avenue for long-term pain alleviation.
Addressing Different Pain Types: Nociceptive and Neuropathic
Ketamine’s versatility shines as it addresses various pain types. In nociceptive pain, arising from tissue damage, ketamine’s anti-inflammatory effects contribute to relief. Neuropathic pain, stemming from nerve damage, sees ketamine’s modulation of central sensitization—an amplified pain response. This dual action makes ketamine a potential multi-faceted solution for a spectrum of pain conditions.
