Vasodilators are used to treat conditions such as hypertension, wherein the patient has an abnormally high blood pressure, as well as angina, congestive heart failure, and erectile dysfunction, and where maintaining a lower blood pressure reduces the patient's risk of developing other cardiac problems. [17]
Vasoactive drug therapy is typically used when a patient has the blood pressure and heart rate monitored constantly. The dosage is typically titrated (adjusted up or down) to achieve a desired effect or range of values as determined by competent clinicians. Vasoactive drugs are typically administered using a volumetric infusion device (IV pump).
Hydralazine is not used as a primary drug for treating hypertension because it elicits a reflex sympathetic stimulation of the heart (the baroreceptor reflex). [9] The sympathetic stimulation may increase heart rate and cardiac output, and in people with coronary artery disease may cause angina pectoris or myocardial infarction. [10]
Vasodilators. These help to open up your blood vessels so blood can flow more easily. This sounds like a lot, but your healthcare provider can recommend the best antihypertensive medication for ...
Some drugs and medications affect heart rate, meaning you may have a lower maximum heart rate and target zone, says Dr. Steinbaum. “If you have a heart condition or take medication, ask your ...
By reducing strain on the heart, this mechanism helps minimise the oxygen demand. Furthermore, calcium sensitizers provide an additional benefit. They open potassium channels in the heart muscle cells, resulting in vasodilation and improved blood flow. [53] This action reduces the workload on the heart.
Taking minoxidil with the following medications may lower blood pressure and cause changes in your heart rate: Diphenhydramine (Benadryl) ... Vasodilators. Beta-blockers. Quick disclaimer: ...
This vasodilation does not decrease the volume of blood the heart pumps, but rather it decreases the force the heart muscle must exert to pump the same volume of blood. Nitroglycerin pills, taken sublingually (under the tongue), are used to prevent or treat acute chest pain.
