Application:
Pregabalin is a second-generation antiepileptic drug (AED) known with the proprietary brand name of Lyrica (Pfizer, Tadworth) in the UK and USA, having a γ-amino butyric acid structure on its molecular structure, which has anticonvulsant effects, and is successfully developed by the company Pfizer for the treatment of peripheral neuropathic pain, or adjuvant treatment of partial seizures. Pregabalin is a Anticonvulsant and antiepileptic drug used to treat epilepsy, neuropathic pain, fibromyalgia, and generalized anxiety disorder. Its use for epilepsy is as an add-on therapy for partial seizures with or without secondary generalization in adults. In December 2008, the US Food and Drug Administration (FDA) approved pregabalin (trade name "Lyrica") for the treatment of diabetic peripheral neuropathic pain (DPN) and postherpetic neuralgia (PHN)which are Both the most common neuropathic pains. Pregabalin has an approved indication and is widely used for the treatment of generalized anxiety disorder. Several randomized, double- blind, placebocontrolled trials found that pregabalin is an effective treatment for patients with generalized anxiety disorder and social anxiety disorder. Dose titration Epilepsy-adjunctive therapy: 25 mg bd for 7 days, to be increased by 50 mg every 7days; usual maintenance 300 mg daily, divided into 2 or 3 doses (max. 600 mg daily, divided into 2 or 3 doses). Generalized anxiety disorder: 150 mg daily, divided into 2 or 3 doses, for 7 days, to be increased by 150 mg every 7 days (max. 600 mg daily, divided into 2 or 3 doses). If stopping pregabalin, it is recommended to taper over at least 1 week to avoid abrupt withdrawal. Cautions Patients with conditions that may precipitate encephalopathy. Patients with severe congestive heart failure.
