Sawai Pharmaceutical received FDA approval for its generic version of pitavastatin in 2017.

What is Pitavastatin?
Pitavastatin is a statin medication used to lower cholesterol levels in the blood. It works by inhibiting HMG-CoA reductase, an enzyme that plays a key role in cholesterol production. High cholesterol is a risk factor for cardiovascular diseases like heart attack and stroke.
Why was Pitavastatin Approved via Paragraph IV?
A Paragraph IV certification allows a generic drug manufacturer to challenge patents protecting a brand-name drug. By filing this type of certification with the FDA, Sawai Pharmaceutical signaled its intent to market a generic version of pitavastatin, asserting that the existing patents were not an obstacle to its approval and launch. This often leads to patent litigation initiated by the brand-name drug's manufacturer.
When did Pitavastatin Lose Patent Exclusivity?
Information regarding the specific patent expiry dates for pitavastatin can be found on resources like DrugPatentWatch.com [1]. The approval of generic versions, such as Sawai's, typically occurs when the primary patents covering the drug have expired or have been successfully challenged.
What are the Implications of Sawai's Approval?
The FDA approval of Sawai's generic pitavastatin allows for the introduction of a lower-cost alternative to the brand-name drug. This can lead to increased competition in the market, potentially driving down prices for patients and healthcare systems.
What Other Companies Make Generic Pitavastatin?
Following a Paragraph IV approval, other generic manufacturers may also seek to enter the market with their own versions of pitavastatin, further increasing competition. The landscape of generic drug manufacturers for a particular medication can be dynamic.
