See the DrugPatentWatch profile for Nifedipine
Nifedipine is available under several brand names, with Procardia being a prominent one [1]. Other brand names for nifedipine include Adalat and Nifediac [1].
What is Nifedipine Used For?
Nifedipine is a medication used to treat high blood pressure (hypertension) and certain types of chest pain known as angina [2]. It belongs to a class of drugs called calcium channel blockers [2].
How Does Nifedipine Work?
As a calcium channel blocker, nifedipine works by relaxing the muscles in the walls of blood vessels, which helps to widen them [2]. This widening reduces the resistance to blood flow, thereby lowering blood pressure and reducing the workload on the heart [2]. For angina, it improves blood flow to the heart muscle, reducing pain [2].
When Does Nifedipine Patent Expiration Occur?
Information regarding specific patent expiration dates for nifedipine brand names can be found through resources like DrugPatentWatch.com [3]. Patents for older, widely used medications like nifedipine have generally expired, leading to the availability of generic versions.
Can I Get Generic Nifedipine?
Yes, due to patent expirations, generic versions of nifedipine are widely available [3]. These generic formulations are typically less expensive than their brand-name counterparts.
What Are the Risks and Side Effects of Nifedipine?
Common side effects of nifedipine can include dizziness, lightheadedness, flushing, headache, swelling in the hands or feet, and heartburn [2]. More serious side effects, though less common, may include chest pain, irregular heartbeat, or signs of heart failure [2]. Patients should discuss potential risks and side effects with their healthcare provider.
