KETAMINE FOR CHRONIC PAIN

Ketamine's pain-relieving properties operate through a fundamentally different mechanism than opioids or traditional analgesics. By modulating AMPA and NMDA receptors in the central nervous system, ketamine interrupts the cycle of central sensitization — the process by which the nervous system amplifies pain signals, causing normal sensations to register as painful.

In chronic pain states, the NMDA receptor becomes chronically overactivated, maintaining a feedback loop that keeps the nervous system in a heightened state of alert. Ketamine blocks this receptor, effectively resetting overactive pain pathways and restoring more normal pain signal processing. This mechanism makes it particularly effective for conditions that have not responded to conventional pain management.

Unlike opioids, ketamine does not carry a risk of respiratory depression at therapeutic doses and has a fundamentally different addiction profile. For patients trapped in cycles of escalating pain medication, ketamine offers a path toward reduced dependence and improved quality of life.

Ketamine protocols for chronic pain differ significantly from those used for mental health conditions. Pain infusions are typically longer in duration — often 2 to 4 hours per session compared to the standard 40-minute mental health infusion — and may involve different dosing strategies tailored to the specific pain condition being treated.

At LUMUS Mind, every pain protocol is individualized. Dr. Garcia evaluates each patient's diagnosis, pain history, current medications, and treatment goals to design an infusion plan optimized for their condition. Some patients benefit from a series of closely spaced infusions over several days, while others respond best to weekly or biweekly sessions.

Throughout each infusion, patients are continuously monitored with vital sign tracking and clinical assessment. Dosing is adjusted in real time based on patient response, ensuring both safety and therapeutic efficacy.

Clinical research supports the use of IV ketamine for a range of chronic pain conditions. Studies on CRPS have demonstrated that multi-day ketamine infusion protocols can produce significant and sustained pain relief, with some patients experiencing months of benefit from a single treatment course. Systematic reviews have confirmed ketamine's efficacy for neuropathic pain, fibromyalgia, and other central sensitization syndromes.

The American Society of Regional Anesthesia and Pain Medicine (ASRA) has published consensus guidelines supporting the use of ketamine infusions for chronic pain, particularly for CRPS and neuropathic pain conditions. Research continues to refine optimal dosing protocols and identify which patients are most likely to benefit from this therapy.
