Cardiovascular Drugs Flashcards
(10 cards)
Cardiac Cycle
The heart, a muscle that contracts thousands of millions
of times in a lifetime, possesses structural and functional
properties that are different from those of other muscles.
Cardiac Conduction
-Each cycle of cardiac contraction and relaxation is controlled by impulses that arise spontaneously in certain pacemaker cells of the sinoatrial (SA) node of the heart.
-These impulses are conducted from the pacemaker cells
by a specialized conducting system that activates all of the
parts of the heart muscle almost simultaneously.
Cardiovascular System
Responsible for delivering oxygen and nutrients to all of the cells of the body and for removing waste products for excretion.
ELECTROCARDIOGRAPHY
Electrocardiography is a process of recording the patterns of electrical impulses as they move through the heart.
CIRCULATION
The purpose of the heart’s continual pumping action is
to keep blood flowing to and from all of the body’s tissues and cells. Blood delivers oxygen and much-needed nutrients to the cells for producing energy, and it carries away carbon dioxide and other waste products of metabolism.
ANGIOTENSIN-CONVERTING-ENZYME
INHIBITORS
- Benazepril (Lotensin)
- Captopril (Capoten)
- Enalapril (Vasotec)
- Enalaprilat (Vasotec IV)
- Fosinopril (Monopril)
- Lisinopril (Prinivil, Zestril),
7/ Moexipril (Univasc) - erindopril (Aceon),
- quinapril (Accupril),
10 ramipril (Altace), and - trandolapril (Mavik)
ANGIOTENSIN II–RECEPTOR BLOCKERS
- azilsartan (Edarbi),
- candesartan (Atacand)
- eprosartan (Teveten),
- irbesartan (Avapro)
- losartan (Cozaar),
- olmesartan (Benicar),
- telmisartan (Micardis),
- valsartan (Diovan).
CALCIUM CHANNEL BLOCKERS
Calcium channel blockers decrease blood pressure,
cardiac workload, and myocardial oxygen consumption. The effects of these drugs on cardiac workload
also make them very effective in the treatment of
angina
VASODILATORS
If other drug therapies do not achieve the desired reduction in blood pressure, it is sometimes necessary to use a
direct vasodilator. Most of the vasodilators are reserved
for use in severe hypertension or hypertensive emergencies
ALPHA-SPECIFIC ADRENERGIC AGENTS
Midodrine (ProAmatine) is an alpha-specifi c adrenergic
agent used to treat orthostatic hypotension—hypotension that occurs with position change—that interferes
with a person’s ability to function and has not responded
to any other therapy
