Purpose

Pregabalin, a non-gamma-aminobutyrate (GABA) receptor agonist or antagonist, is a novel calcium channel regulator that can block voltage-dependent calcium channels and reduce the release of neurotransmitters. It is mainly used for neuralgia associated with diabetic peripheral neuropathy, post-herpetic neuralgia and adjuvant treatment of adult partial seizures, generalized anxiety disorder, central neuralgia (including neuralgia associated with spinal cord injury, stroke and multiple sclerosis) and fibromyalgia.

Pharmacologic action

Pregabalin has a good therapeutic effect on epilepsy, and various animal epilepsy model studies have shown that pregabalin can significantly prevent seizures, and the dose of its active effect is 3-10 times lower than gabapentin. Pregabalin was found to reduce sensory and motor spinal reflexes in rat clamp toe stimulation, reduce behaviors associated with diabetic Chemicalbook, peripheral nerve injury, or chemotherapy in neuropathic animal pain models, and inhibit or reduce pain-related behaviors caused by spinal administered stimuli. Animal studies have found that pregabalin may have advantages in combination with opioids. Pregabalin provides a new option for the clinical treatment of neuropathic pain.
