🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by combining the peripheral and central pain-modulating effects of amitriptyline and ketamine. Amitriptyline, when applied topically, is believed to block voltage-gated sodium channels and alpha-adrenergic receptors on sensory nerve endings, thereby reducing ectopic nerve firing and pain signal transmission. Ketamine acts as a non-competitive antagonist at the NMDA receptor, which is involved in central sensitization and wind-up. By blocking NMDA receptors in the skin and underlying tissues, ketamine helps prevent the amplification of pain signals. The combination is thought to provide synergistic relief for neuropathic pain with fewer systemic side effects than oral formulations.
