|Brand Names of Drugs That Are Calcium Channel Blockers Photo Caption Calcium channel blockers treat conditions affecting the heart and blood vessels. Although generic medications often provide the advantage of cost savings, as indicated by the Consumer Reports Health website, depending on the condition and the symptoms, many doctors prefer for patients to take brand name drugs. Role of Calcium Cells require a delicate balance of minerals in order to function properly. Muscle cells, which include those muscle cells contained in the heart, need calcium in order to contract and magnesium in order to relax. Heart muscle cells store calcium in a structure known as the sarcoplasmic reticulum, or SR. Electrical impulses in the heart signal a specialized protein in the SR, known as the calcium pump, to release calcium into the main body of the cell, which then stimulates the cell to contract. Because each cell is interconnected, all cells contract in unison, as described by the Cells Alive website. Mechanism of Action that damage the cells and affect the ability of the SR to hold calcium or the ability of the calcium pump to operate allow too much calcium to remain in the body of the cell. This interferes with the cell s ability to respond appropriately to the electrical impulses, leading to weak contractions. As calcium accumulates in the cell, it can lead to cell death, which contributes to the onset of a variety of conditions. High blood pressure, a condition known as hypertension, causes the pressure the blood exerts ugg australian on the walls of the blood vessels to increase. Over time, high blood pressure damages the walls of blood vessels and can affect their ability to pump calcium appropriately. Angina, also known as chest pain, occurs when the heart muscle fails to receive enough blood and oxygen. Arrhythmia, or irregular heartbeats, occurs when the heart muscle cells fail to contract in unison. Calcium channel blockers relax the walls of blood vessels, allow the vessels to dilate and slow the heart rate.
