Neugaba 25 mg Capsule contains Pregabalin as its active ingredient. Pregabalin is a structural derivative of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). It binds with high affinity to the alpha₂-δ subunit of voltage-gated calcium channels in the central nervous system, modulating the release of several excitatory neurotransmitters. This mechanism helps in reducing neuronal excitability, thereby alleviating symptoms associated with various neurological and psychiatric conditions.
