Pregabalin is a medication used to treat neuropathic pain, epilepsy, and generalized anxiety disorder. It works by binding to a specific subunit (alpha2-delta) of voltage-gated calcium channels in the central nervous system, reducing the release of several neurotransmitters involved in pain signaling and anxiety. Pregabalin is available in capsule form and should be taken orally as directed by a healthcare professional. It may cause side effects such as dizziness, drowsiness, weight gain, and dry mouth. It is important to follow the dosage instructions carefully and not to stop taking the medication abruptly without consulting a doctor.
