Understanding Gabapentin: An Overview of the Medication

Gabapentin is a widely prescribed medication that belongs to the class of anticonvulsants. It is primarily used to treat epilepsy, neuropathic pain, and various other conditions. The 300 mg tablet is one of the most common dosage forms of gabapentin, offering a balance between efficacy and manageable side effects.

Gabapentin works by affecting the way nerves send messages to the brain. It binds to specific receptors in the nervous system, reducing the release of excitatory neurotransmitters and thus helping to control seizures and alleviate pain.
