Anticonvulsants reduce neuronal excitability and are widely used for neuropathic pain, seizure disorders, fibromyalgia, and anxiety. Compounded topical formulations allow local delivery to painful areas without systemic sedation.
Gabapentin and pregabalin bind to the alpha-2-delta subunit of voltage-gated calcium channels, reducing neuronal calcium influx and excitatory neurotransmitter release. This dampens pain signal transmission and epileptic activity.
Topical gabapentin, pregabalin, and amitriptyline formulations deliver medication locally with minimal systemic absorption. Custom dose oral formulations, combination compounds for neuropathic pain, and liquid versions for dysphagic patients require compounding.
Gabapentin and pregabalin are FDA-approved for neuropathic pain and epilepsy. Compounded topical gabapentin is widely prescribed but lacks FDA approval. Gabapentin is now a Schedule V controlled substance in many states due to misuse potential. Prescriptions are required.
