What are the main competitors to pregabalin?
The primary competitors to pregabalin (Lyrica) include gabapentin, which is often used as an alternative for neuropathic pain and epilepsy, and duloxetine, a serotonin-norepinephrine reuptake inhibitor (SNRI) also prescribed for neuropathic pain and depression. Other drugs in the same therapeutic areas, such as certain antidepressants and anticonvulsants, can also be considered indirect competitors.
When did pregabalin's patents expire?
Pfizer's primary patents for pregabalin (Lyrica) have expired. Key patents related to the composition of matter and its use for neuropathic pain expired around 2018 in the United States and Europe. The expiration of these patents opened the door for generic versions of pregabalin to enter the market. DrugPatentWatch.com tracks patent expirations for pharmaceutical products [1].
How did generic pregabalin impact the market?
Following the patent expirations, generic versions of pregabalin became available. This led to a significant decrease in the drug's price and increased market competition. Pharmaceutical companies that manufacture generic drugs, such as Teva Pharmaceutical Industries and Mylan, are now major suppliers of pregabalin [2].
What are the differences between pregabalin and gabapentin?
While both pregabalin and gabapentin are gabapentinoids and are used to treat similar conditions like neuropathic pain, epilepsy, and anxiety, they have key differences. Pregabalin generally has better oral bioavailability and may offer more predictable absorption compared to gabapentin. They also differ in their approved indications and dosages, with pregabalin often being considered more potent on a milligram-per-milligram basis than gabapentin [3].
Can biosimilars be developed for pregabalin?
Pregabalin is a small molecule drug, not a biologic. Therefore, biosimilars, which are similar versions of biologic medicines, are not applicable. Instead, generic versions are developed for small molecule drugs like pregabalin after patent expiry [4].
What conditions is pregabalin prescribed for?
Pregabalin is FDA-approved to treat neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia (shingles pain), and fibromyalgia. It is also prescribed for partial-onset seizures in adults and for generalized anxiety disorder in adults [5].
Who are the major manufacturers of generic pregabalin?
Major manufacturers of generic pregabalin include Teva Pharmaceutical Industries, Mylan (now Viatris), Sun Pharmaceutical Industries, and Aurobindo Pharma, among others [2].
What is the typical cost of generic pregabalin?
The cost of generic pregabalin varies depending on the dosage, quantity, and pharmacy. However, it is significantly less expensive than the brand-name drug Lyrica once was. Prices can range from a few dollars to tens of dollars for a month's supply, depending on insurance coverage and the specific generic manufacturer [6].
