Peter Attia MD - Chronic Pain & Muscle Relaxants: Neurontin and Baclofen | Sean Mackey, M.D., Ph.D.
The discussion highlights the use of blephin as a muscle relaxant, which is not as potent as others like Valium but offers fewer side effects such as drowsiness and nausea. Blephin is considered safe, non-habit forming, and suitable for short-term use in acute or subacute conditions. It is also used intrathecally for severe spasticity in spinal cord injuries. The conversation also covers Neurontin (Gabapentin) and its cousin Pregabalin, which are used for neuropathic pain. These drugs work by modulating signals in the spinal cord and brain, offering effective pain relief without a lethal dose. However, they can cause side effects like drowsiness and weight gain. Neurontin is particularly noted for its role in managing peripheral nerve injury pain, although it can cause fatigue at high doses. Pregabalin is preferred when higher doses are needed due to its linear kinetic profile, allowing more drug to enter the system.
Key Points:
- Blephin is a safe, non-habit forming muscle relaxant suitable for short-term use.
- Neurontin and Pregabalin are effective for neuropathic pain, with no lethal dose but potential side effects like drowsiness.
- Intrathecal use of blephin is beneficial for severe spasticity in spinal cord injuries.
- Pregabalin allows higher dosing due to its linear kinetic profile, useful for severe pain.
- Chronic pain is defined by persistence beyond expected tissue healing, not by a fixed timeframe.
