 Pregabalin works by reducing the abnormal electrical activity in the brain. It is taken alongside other medicines for epilepsy. Pregabalin can also be helpful in treating the symptoms of generalised anxiety disorder (GAD), particularly if other medicines which are more often prescribed for people with this condition are not suitable. GAD is a long-term condition where anxiety is a major symptom.
 Pregabalin, also known as isobutyl--Aminobutyric acid (-isobutyl-GABA) and sold under the trade name Lyrica among others, is a medication used to in the treatment of 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.

Its a ion channel modulator that has analgesic, anticonvulsant, sedative, and anxiolytic properties. Pregabalin is a potent gabapentinoid and close analogue of GABOB (-hydroxy-GABA), baclofen (-(4-chlorophenyl)-GABA), and phenibut (-phenyl-GABA).
