Pfizer manufactured the original branded version of pregabalin, marketed as Lyrica [1].
Who Else Makes Pregabalin?
Following patent expirations, other pharmaceutical companies have begun manufacturing generic versions of pregabalin. The availability of these generics has increased competition in the market [2].
When Did Lyrica's Patent Expire?
Lyrica's primary U.S. patents expired in 2019 [3]. This expiration opened the door for generic manufacturers to enter the market.
What Is Pregabalin Used For?
Pregabalin is prescribed to treat neuropathic pain, which is a type of pain caused by nerve damage [1]. It is also used to manage epilepsy by controlling partial seizures and to treat generalized anxiety disorder [1][4].
How Does Pregabalin Work?
Pregabalin belongs to a class of drugs called anticonvulsants or anti-epileptic drugs. It works by affecting chemicals in the body that send pain signals across the nervous system [4]. By reducing abnormal electrical activity in the brain, it helps to prevent seizures [4]. It also calms down nerve overactivity that can cause seizures and anxiety [4].
What Are the Potential Side Effects of Pregabalin?
Common side effects of pregabalin include dizziness, drowsiness, blurred vision, dry mouth, and weight gain [1]. More serious side effects can include changes in mood or behavior, suicidal thoughts, and severe allergic reactions [1][4].
