Felodipine is primarily used as a medication to manage high blood pressure (hypertension) and certain types of chest pain (angina). It belongs to a class of drugs known as calcium channel blockers, which work by relaxing the blood vessels, allowing blood to flow more easily and reducing the workload on the heart. This helps to lower blood pressure and improve oxygen supply to the heart muscle, alleviating symptoms of angina. It is often prescribed when other treatments are not effective or suitable. Patients are typically advised to take it regularly to maintain its benefits, and it is commonly available in extended-release tablets to ensure a steady effect throughout the day. As with any medication, it should be used under medical supervision to monitor its effectiveness and manage any potential side effects.
