Baclofen, sold under the brand name Lioresal among others, is a medication used to treat muscle spasticity, such as from a spinal cord injury or multiple sclerosis. [8] [9] It may also be used for hiccups and muscle spasms near the end of life, [9] and off-label to treat alcohol use disorder [10] [11] or opioid withdrawal symptoms. [12]
Spasticity is often treated with the drug baclofen, which acts as an agonist at GABA receptors, which are inhibitory. Spastic cerebral palsy is the most common form of cerebral palsy, which is a group of permanent movement problems that do not get worse over time. GABA's inhibitory actions contribute to baclofen's efficacy as an anti-spasticity ...
is pretty meaningless. Baclofen DOES produce euphoria and "high" in dosage of about 125mg, a halfway between alcohol and "Extasy" (MDMA) experience. Just buy it and try it if you need a proof. — Preceding unsigned comment added by 94.102.122.86 18:45, 7 March 2017 (UTC) Indeed, baclofen definitely has abuse potential. You don't need to go far ...
For many years, it was believed that the axon hillock was the usual site of initiation of action potentials—the trigger zone. It is now thought that the earliest site of action potential initiation is at the axonal initial segment: just between the peak of the axon hillock and the initial (unmyelinated) segment of the axon.

Arbaclofen placarbil (/ ɑːr ˈ b æ k l oʊ f ɛ n p l ə ˈ k ɑːr b ɪ l / ar-BAK-loh-fen plə-KAR-bil, also known as XP19986) is a prodrug of R-baclofen.Arbaclofen placarbil possesses more favorable pharmacokinetic profile than baclofen, with less fluctuations in plasma drug levels.
Gabapentinoids are selective for the α 2 δ site but non-selective when they bind to the calcium channel complex. They act on the α 2 δ site to lower the release of many excitatory and pro-nociceptive neurochemicals, including glutamate, substance P, calcitonin gene-related peptide (CGRP), and more.

Many commonly used sedative and anxiolytic drugs that affect the GABA receptor complex are not agonists. These drugs act instead as positive allosteric modulators (PAMs) and while they do bind to the GABA receptors, they bind to an allosteric site on the receptor and cannot induce a response from the neuron without an actual agonist being present.
