Antihypertensives Flashcards
When do we treat BP
130/80
Primary vs secondary HT
primary no cause
difference between 1st line antihypertensives and second line what are the classes for each?
first -proven to decrease morbidity and mortality
1-Diuretics, ACE, ARB, CCBs
2- adrenergic antagonists-beta blockers and direct acting vasodilators
where are ang 1 and 11 in the body?
1-In the blood
11- in the lungs endothelium
what does Ang 11 do? 3 be specific
Vasoconstricts VASCULAR smooth mm
Increases sympathetic Nervous system
Increases aldosterone-increases Na+ reabsorption
What three things do ACE inhibs do?
Decrease peripheral resistance
decrease blood volume
decrease hypertrophy- added benefit
ACE inhib saying
In ACEPRIL Brady lost a baby because of heartfail, HTN and Acute MI
What does a build up of bradkinin do in the body and one more thing about it
It causes inflammation angioedema, and cough
Small chance of hyperK because of decrease in aldosterone
What does aldosterone do?
A steroid hormone made by the adrenal cortex (the outer layer of the adrenal gland). It helps control the balance of water and salts in the kidney by keeping sodium in and releasing potassium from the body.
What is the difference between ARBS and ACE inhibs?
The site-
ARBS- block ANG 11 at site so ang 2 is still made
Uses of ARBS 5
prevents HTN, scaring, renal damage, decrease in diabetic neuropothy and decrease stroke risk
ARBs trick and 2 things
At the start of Arbor day. I took lithium and lost a baby
Plus hypo risks including HA and angioedema and cough are rare because there is not a build up of bradykinin
Differences in CCB
What they do and drug names
Dihydropyridines and non- Nifedipine
d-Vascular smooth mm
nond- Vascular smooth mm and Myocardium so works on dysR
both- HTN and Angina-Verapamil and diltrazem
AE of nifedipine and way to remember it
increase dig levels=bradycardia alcohol=increase in vasodilation and drop in BP
a wet knife gives you a chub
How to remember the dihydropyridines
vera likes to use a dry dildo it can decrease or increase her heart rate and she likes to drink wine because grapefruit juice increases the effects of her drug and decreases her HR shes peripheral edema
Reflex tachy
120-130
Beta blockers
Adrenergic antags beta blockers
Block fight or flight decrease bp, hr, co
LOL at a blockbuster is good for your heart
What is first line for HTN
Diuretics, ACE, ARBS, CCBS
