Pregabalin

What Is Pregabalin?

Pregabalin is a central nervous system (CNS) active drug that mimics the neurotransmitter GABA (gamma-aminobutyric acid), although it doesn’t bind to GABA receptors. It primarily targets the alpha-2-delta subunit of voltage-gated calcium channels in the brain and spinal cord, which helps reduce neuropathic pain and control seizure activity.

Pregabali’n is approved by the U.S. Food and Drug Administration (FDA).

Chemical Properties:

• Chemical name: (S)-3-(aminomethyl)-5-methylhexanoic acid
• Drug class: Anticonvulsant / Neuropathic pain agent
• Controlled substance: Schedule V in the U.S. (due to potential for abuse)
