SAS#17 Flashcards
Effect different areas of blood pressure control so in most cases, these agents are combined for synergistic effect
ANTIHYPERTENSIVE DRUGS
Blank cases of hypertension have no known case
What is the main action of antihypertensive
TO ALTER THE BODY’S REGULATING MECHANISMS (baroreceptors, raas etc)
Responsible for maintaining normal blood pressure
BODY’s REGULATING MECHANISMS
Baroreceptors
Renin-angiotensin-aldosterone system
Different people have different responses towards hypertensive agents because hypertension is
MULTIFACTORIAL
Elevated blood pressure
is a serious medical condition that significantly increases the risk of heart brain kidney and other diseases
HYPERTENSION
There is elevated total peripheral resistance. Also the organs are perfused effectively and people with_usually exhibit no symptoms. It is also the reason why hypertension is tagged as the silent killer
ESSENTIAL HYPERTENSION
Is characterized by elevated blood pressure due to a known cause
SECONDARY HYPERTENSION
A tumor in the adrenal medulla called ___can caused the organ to release a high amount of catecholamines which greatly increase blood pressure
PHAEOCHROMOCYTOMA

CONTRACTION
RESTING
Are antihypertensive agents that act in the lungs to prevent the conversion of angiotensin 1 into angiotensin ll, which is a potent vasoconstrictor
ANGIOTENSIN CONVERTING ENZYME INHIBITORS (ACE)
By preventing the production of angiotensin ll, which is a potent vasoconstrictor and a stimulator of aldosterone release, blood pressure is decreased with resultant loss of serum sodium and fluid but with a slight increase in serum potassium
ACE INHIBITORS
Angiotensin ll is a
POTENT VASOCONSTRICTOR
ACE , aside from its indication in treating hypertension it is also combined with ____ in the treatment of
DIURETICS AND DIGOXIN
HEART FAILURE AND LEFT VENTRICULAR DYSFUNCTION
Ace inhibitors is also approved for treatment of ____ in which the renal artery is being damaged by diabetes
DIABETIC NEPHROPATHY
Contraindications and cautions in ace that is can be exacerbated by the therapeutic effects of the drug
HYPONATREMIA AND HYPOVOLEMIA
Can cause potential adverse effect to the fetus and can decrease milk production
ACE INHIBITORS
Pregnant women are advised to use barrier type of contraceptives while taking this drug
ACE INHIBITORS
Is associated with sometimes fatal pancytopenia, cough and gi distress
