What class of medications does Nifedipine belong to?

Nifedipine is classified as an antihypertensive medication that operates as a calcium channel blocker. This means that it works primarily by inhibiting the influx of calcium ions into smooth muscle cells and cardiac muscle cells, resulting in relaxation of the vascular smooth muscle and subsequent vasodilation. The dilation of blood vessels lowers blood pressure, making it effective in treating hypertension. Additionally, this mechanism helps in managing angina by reducing the workload of the heart.

In contrast, diuretics primarily work by increasing urine output to reduce fluid overload and lower blood pressure, antibiotics are used to fight bacterial infections, and anti-inflammatory medications are utilized to reduce inflammation and pain, often associated with conditions like arthritis. These distinctions highlight why Nifedipine is correctly categorized under antihypertensives and specifically as a calcium channel blocker.
