Kalciumcsatornablokkoló

Kalciumcsatornablokkoló is the Hungarian term for calcium channel blocker. Calcium channel blockers are a class of drugs used to treat a variety of medical conditions, primarily those affecting the heart and blood vessels. They work by blocking the entry of calcium into cells, particularly those in the heart muscle and the walls of blood vessels. This action leads to several effects.

In the heart, blocking calcium channels can slow the heart rate and reduce the force of contraction, which is beneficial in conditions like angina (chest pain) and certain types of arrhythmias (irregular heartbeats). In the blood vessels, calcium channel blockers cause vasodilation, meaning they relax and widen the blood vessels. This reduces peripheral resistance, making it easier for the heart to pump blood and thereby lowering blood pressure. Consequently, these medications are widely prescribed for hypertension (high blood pressure).

Different types of calcium channel blockers exist, categorized based on their chemical structure and their primary effects. Some primarily affect the heart, while others have a more pronounced effect on blood vessels. They are available in various formulations, including oral tablets and injections. Common side effects can include dizziness, headache, flushing, and swelling in the extremities. The choice of a specific calcium channel blocker depends on the individual patient's condition and medical history.
