Nicardipine, a calcium channel blocker used to treat high blood pressure and angina, has been a widely prescribed medication for decades. However, with the expiration of its original patent, pharmaceutical companies are now racing to develop new formulations and delivery systems to maintain market share. In this article, we'll delve into the current patent landscape of nicardipine and explore whether its patent application has been approved.
What is Nicardipine?
Nicardipine is a dihydropyridine calcium channel blocker that works by relaxing blood vessels and reducing blood pressure. It's commonly used to treat hypertension, angina, and other cardiovascular conditions. The medication was first approved by the FDA in 1985 under the brand name Cardene.
Patent Expiration and Generic Entry
