Cardiovascular drugs Flashcards
(35 cards)
Function of Cardiac glycosides
slows the ventricular heart rate.
Increases myocardial contractility
Function of Phosphodiesterase inhibitors
Increases myocardial
contractility, dilates blood
vessels
Function of Angiotensin-converting enzyme (ACE) inhibitors
Vasodilation and reduces Na
and H20 retention
Function of Calcium channel blockers
Reduces contractility of the
heart, slows HR, dilates blood
vessels
Function of Antiarrhythmics
Controls abnormal cardiac
rhythm
Function of Nitroglycerides
Dilates blood vessels
Function of Diuretics
Increases urine production by the kidney
Function of Beta blockers
Decrease HR and improve
ventricular filling
What is used for Emergency treatment of CHF
Nitroglycerides
What part of kidney Loop diuretics act on
loop of Henle
What part of the kidney do Thiazide diuretics:
hydrochlorothiazide
act on
distal convoluted tubule, inhibiting reabsorption of
sodium ions
what part of the kidney do Potassium sparing diuretics act on?
distal tubule
drug example of a Loop diuretics
Frusimide
Diuretics are contra-indicated in patients who are suffering from
dehydration or anuria
Cardiac glycosides act on
Heart
Phosphodiesterase inhibitors
Blood vessels
Angiotensin converting enzyme (ACE) inhibitor act on
heart, blood vessels and kidneys
Calcium channel blockers act on
heart, blood vessels
Antiarrhythmics act on
Heart
Nitroglycerides act on
blood vessels
Sympathomimetics act on
heart and blood vessels
Beta blockers act on
Heart
What is meant by inotropic stimulation of the heart?
Increasing the strength of contraction and therefore increasing cardiac output
What type of drug is Procainamide
Anti dysrhythmics
