Pregabalin (INN) (pronounced/prɨˈgæbəlɨn/) is an anticonvulsant drug used for neuropathic pain, as an adjunct therapy for partial seizures, and in generalized anxiety disorder. It was designed as a more potent successor to gabapentin. Pregabalin is marketed by Pfizer under the trade name Lyrica.
Recent studies have shown that pregabalin is effective at treating chronic pain in disorders such as fibromyalgia and spinal cord injury
It is considered to have a dependence liability if misused, and is classified as a Schedule V drug in the U.S.
Pregabalin was initially developed by medicinal chemist Richard Bruce Silverman at Northwestern University in the United States. The drug was approved in the European Union in 2004. Pregabalin received U.S. Food and Drug Administration (FDA) approval for use in treating epilepsy, diabetic neuropathy pain and post-herpetic neuralgia pain in June 2005, and appeared on the U.S. market in fall 2005.
Rare (<0.1% of patients): neutropenia, first degree heart block, hypotension, hypertension, pancreatitis, dysphagia, oliguria, rhabdomyolysis
No pharmacokinetic interactions have been demonstrated in vivo. The manufacturer notes some potential pharmacological interactions with oxycodone, lorazepam and ethanol (alcohol). Concurrent use may increase the central nervous system effects of these medications (e.g. drowsiness, effects on concentration).
