Pregabalin and gabapentin are structurally similar to GABA.

Pregabalin (marketed as Lyrica®) is structurally similar to gabapentin. It is an analog of gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system. Although pregabaliln does not act on GABA receptors, it may increase the "density of GABA transporter protein and increases the rate of functional GABA transport".[1] It is approved by the FDA for neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia adjunctive therapy for adult patients with partial onset seizures, and fibromyalgia.[1]

Chemistry

The IUPAC chemical name for pregabalin is (S)-(+)-3-(aminomethyl)-5-methylhexanoic acid. Its chemical formula is C8H17NO2 giving it a molecular mass of 159.23 g/mol. It is both an amine and a carboxylic acid.

Clinical uses

Pregabilin is "likely to be beneficial" in the treatment of generalized anxiety according to Clinical Evidence.[2]

Drug toxicity

At maximum doses of 600 mg per day, drug toxicity from pregabalin may include reduced cognitive function.[3]
