Gabapentinoids

Pregabalin, sold under the brand names Axalid and Lyrica among others, is an anticonvulsant, analgesic, and anxiolytic amino acid medication used to treat epilepsy, neuropathic pain, fibromyalgia, restless legs syndrome, opioid withdrawal, generalized anxiety disorder (GAD), and postherpetic neuralgia (a type of nerve damage that can result from shingles). Pregabalin also has antiallodynic properties. Its use in epilepsy is as an add-on therapy for partial seizures. When used before surgery, it reduces pain but results in greater sedation and visual disturbances. It is taken by mouth.

Gabapentin, sold under the brand name Neurontin among others, is an anticonvulsant medication used to treat neuropathic pain (postherpetic neuralgia) and partial seizures of epilepsy. Gabapentin is a central nervous system (CNS) depressant and derivative of the inhibitory neurotransmitter, GABA. It is used for the treatment of neuropathic pain caused by diabetic neuropathy, postherpetic neuralgia, and central pain. It is moderately effective: about 30–40% of those given gabapentin for diabetic neuropathy or postherpetic neuralgia have a meaningful benefit.

Baclofen, sold under the brand name Lioresal among others, is a central nervous system (CNS) depressant and derivative of the inhibitory neurotransmitter, γ-Aminobutyric acid (GABA). It is a skeletal muscle relaxant medication used to treat muscle spasms, muscle spasticity, such as from a spinal cord injury or multiple sclerosis. Baclofen is a potent GABAB receptor agonist. It may also be used for hiccups and muscle spasms near the end of life, and off-label to treat alcohol use disorder or opioid withdrawal symptoms. It is taken orally or by intrathecal pump (delivered into the spinal canal v

Phenibut, sold under the brand name Anvifen among others, is a central nervous system (CNS) depressant with anxiolytic effects, and is used to treat anxiety, insomnia, and for a variety of other indications. It is usually taken orally (swallowed by mouth), but may be given intravenously.

chemical compound

Gabapentinoids, also known as α2δ ligands, are a class of drugs that are chemically derivatives of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) (i.e., GABA analogues) which bind selectively to the α2δ protein that was first described as an auxiliary subunit of voltage-gated calcium channels (VGCCs).

Mirogabalin (brand name Tarlige; developmental code name DS-5565) is a gabapentinoid medication developed by Daiichi Sankyo. Gabapentin and pregabalin are also members of this class. As a gabapentinoid, mirogabalin binds to the α2δ subunit of voltage-gated calcium channel (1 and 2), but with significantly higher potency than pregabalin. It has shown promising results in Phase II clinical trials for the treatment of diabetic peripheral neuropathic pain.

Atagabalin (, ; developmental code name PD-0200390) is a drug developed by Pfizer and related to gabapentin, which similarly binds to the α2δ calcium channels (1 and 2). It was under development as a treatment for insomnia, but was discontinued following unsatisfactory trial results. The drug reached phase 2 clinical trials for this indication prior to the discontinuation of its development.
