Gabapentin 300 mg is a prescription medication commonly used to treat various medical conditions, including epilepsy, anxiety disorders, and neuropathic pain. As a derivative of the neurotransmitter gamma-aminobutyric acid (GABA), gabapentin works by modulating the activity of GABA receptors in the brain, which helps to regulate neuronal excitability and reduce pain transmission.
Initially developed as an antiepileptic medication, gabapentin has since been found to have a wide range of therapeutic applications. Its exact mechanism of action is not fully understood, but it is believed to involve the modulation of voltage-gated calcium channels, which play a crucial role in the transmission of pain signals.
