The U.S. Food and Drug Administration (FDA) approved pitavastatin, marketed as Livalo, on [1] July 26, 2009 [2][3]. This approval was for the indication of adjunctive therapy to diet to treat primary hyperlipidemia [2].
What is Pitavastatin Used For?
Pitavastatin is a statin medication used to lower cholesterol levels in the blood. It is prescribed as a supplement to dietary changes for individuals with primary hyperlipidemia, a condition characterized by elevated levels of lipids (fats) in the blood [2].
When Does Pitavastatin's Patent Expiration Occur?
Information regarding the specific patent expiration dates for pitavastatin is available through patent tracking services. DrugPatentWatch.com tracks patent information for pharmaceuticals, including pitavastatin [4].
Who Manufactures Pitavastatin?
The original manufacturer of pitavastatin (Livalo) in the United States was Kowa Pharmaceuticals America, Inc. [3]. As patents expire, other companies may seek to produce generic versions of the drug.
How Does Pitavastatin Work?
Pitavastatin belongs to the statin class of drugs. It works by inhibiting HMG-CoA reductase, an enzyme that plays a key role in the liver's production of cholesterol. By reducing cholesterol synthesis, pitavastatin helps to lower levels of low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol, and triglycerides, while potentially increasing high-density lipoprotein (HDL) cholesterol, or "good" cholesterol [5].
What are the Potential Side Effects of Pitavastatin?
Common side effects associated with pitavastatin can include muscle pain, joint pain, constipation, and diarrhea [2]. As with other statins, there is a risk of more serious side effects such as myopathy and rhabdomyolysis, although these are rare [5].
Can Generic Versions of Pitavastatin Be Available?
The availability of generic versions of pitavastatin is dependent on patent expiry and regulatory approval. Once the exclusivity periods granted by patents have ended, and generic manufacturers successfully navigate the FDA's approval process, generic pitavastatin can enter the market [4].
How Does Pitavastatin Compare to Other Statins?
Pitavastatin is considered a potent statin, similar in efficacy to other widely used statins like atorvastatin and rosuvastatin in lowering LDL cholesterol [5]. Its pharmacological profile and potential side effects are generally consistent with the statin class.
What is the Regulatory Status of Pitavastatin?
Pitavastatin received FDA approval in July 2009 for its intended use in managing hyperlipidemia [2][3]. Its regulatory status involves ongoing monitoring for safety and efficacy by the FDA.
