Gabapentin

Overview

Basic Info

SummaryGabapentin is a small molecule drug developed by Pfizer that functions as a CACNA2D2 and Cav2.2 blocker. The drug has been approved for the treatment of various conditions, including anxiety, cough, diabetic neuropathies, epilepsy, fibromyalgia, restless legs syndrome, and seizures. Gabapentin's mechanism of action involves blocking the influx of calcium ions into neurons, thereby reducing their excitability and relieving symptoms such as pain and convulsions. Since its initial approval in 1993, Gabapentin has become a widely prescribed medication for the treatment of these conditions. However, it is important to note that Gabapentin may cause certain side effects, such as drowsiness, dizziness, and difficulty with coordination. Therefore, its use must be closely monitored by healthcare providers, and patients should follow the prescribed dosage and usage guidelines.
