Drugs useful in treating tachycardias (abnormally rapid heart rates).
These medicines for angina (chest pain) and high blood pressure affect the movement of calcium into the cells of the heart and blood vessels, relax blood vessels, and increase the flow of blood and oxygen to the heart. Examples of calcium channel blockers include diltiazem (Cardizem), nifedipine (Procardia), and verpamil (Isoptin).
Drugs used in the treatment of hypertension and angina; their mechanism of action involves opening up blood vessels
used for heart disease and for patients recovering from stroke, these drugs stablize the cranial blood vessels. Expansion of the blood vessels is acknowledged as a factor in migraine.
Calcium (Ca+) is required for contraction of muscle and regulation of blood vessels. These drugs are used to slow the transport of calcium across the muscle and blood vessel cell membranes. The results are a decrease in chest discomfort, blood pressure, and irregular heart beats for which these drugs are primarily used. Commonly used Ca+ channel blockers include: Cardizem¨ , Cardene¨ , Verapamil¨ , and Procardia¨ . Occasional side effects include fatigue, headache, palpitations or skipped beats, light-headedness, leg/ankle swelling, nausea.
Medicines that can lower blood pressure.
one kind of hypertension medicine that slows the movement of calcium into the cells of the heart and the walls of the arteries (blood vessels that carry blood from the heart to the tissues) — This relaxes the arteries and reduces the pressure in the blood vessels.
Medications that decrease blood pressure by relaxing arteries and veins.
sometimes used to help lower blood pressure and improve blood circulation in the heart.
A class of drugs that act by selective inhibition of calcium influx through cell membranes or on the release and binding of calcium in intracellular pools. Since they are inducers of vascular and other smooth muscle relaxation, they are used in the drug therapy of hypertension and cerebrovascular spasms, as myocardial protective agents, and in the relaxation of uterine spasms.
Drugs used to treat chronic angina, high blood pressure, and other conditions. Calcium that enters cells can cause a tightening of the arteries, higher blood pressure, and increased workload on the heart. Calcium channel blockers may help reduce the amount of calcium that enters cells. Arteries are then able to widen, and blood pressure decreases. Some calcium channel blockers may help decrease the strength of the heartbeat, while others may decrease the rate of the heartbeat. Both methods may help decrease the workload on the heart and the amount of oxygen it requires to work effectively.
A major class of drugs often used in the treatment of angina and hypertension. By decreasing bladder contractility, they can induce urinary retention and cause overflow UI.
Medicines that lower blood pressure, relieve chest pain, and stabilize normal heart rhythms by inhibiting calcium movement into the heart muscles and smooth muscle cells. They are used to treat a variety of conditions and to prevent circulatory and kidney problems in scleroderma.
Group of vasodilating drugs that are effective in high blood pressure; and of some use in pulmonary arterial hypertension (PAH) at high doses.
A group of drugs used in treatment of angina, hypertension, and cardiac arrhythmias. They work by inhibiting the effect of calcium on the muscles of arteries, thereby reducing the degree of contraction. this results in a decrease in the workload of the heart, a decrease in blood pressure, and improved circulation of blood.
Drugs that reduce how much the muscle walls of arteries tighten; work by suppressing the effect of calcium on these muscles.
A form of medication used to treat high blood pressure and heart disease.
Drugs that limit calcium entry into the cells, where it stimulates contraction. When calcium entry is limited, blood vessels become dilated and the frequency and force of heart contractions are decreased. Calcium channel blockers are used to: 1) treat angina, 2) reduce blood pressure, and 3) suppress certain cardiac arrhythmias.
Medicines that keep calcium from entering the muscle cells of the heart and blood vessels. As a result, blood vessels relax and increase the supply of blood and oxygen to the heart.
Drugs that lower blood pressure by relaxing arteries and veins.
A group of drugs that slows the influx of calcium ions into the muscle cells. This results in decreased arterial resistance and decreased myocardial oxygen demands.
