Amlodipine is a medication commonly used to treat high blood pressure and certain types of chest pain, known as angina. It belongs to a class of drugs called calcium channel blockers, which work by relaxing the blood vessels, allowing blood to flow more easily. This helps to lower blood pressure and reduce the heart's workload. Patients typically take amlodipine once daily, and it can be used alone or in combination with other medications. Common side effects may include swelling in the legs or ankles, dizziness, and flushing. It is important to follow a healthcare provider's instructions when using this medication.
