Classes of drugs Flashcards
What do beta blockers do?
reduce o2 demand of the heart muscle
affects beta 1 and beat 2
What is the effect of beta-blockers on beta 1?
cardiac stimulation
blocks the effect of
epi and norepi
thereby reducing HR
what is the effect of beta-blockers on beta 2?
bronchial relaxation
dilates blood vessels
therefore reducing BP
What are beta-blockers used for treatment?
Slowing HR and lowering blood pressure
What is the common suffix of BETA BLOCKERS?
~olol
What do calcium channel blockers do?
relax smooth muscle and decrease peripheral resistance
(slows HR and lowers BP)
What are calcium channel blockers used to treat?
HTN
Calcium channel blockers typical suffixes:
~ine
What do diuretics do to the body?
act on the KIDNEYS to excrete MORE water from the body
decreases BP by decreasing blood volume
increase the elimination of water, sodium, and electrolytes
then reduces BP by reducing peripheral resistance (by decreasing BV and CO)
What are the 5 different types of diuretics?
LOOP
Osmotic
carbonic anhydrase inhibtors
thiazide
potassium sparing
What are loop diuretics?
inhibits Na+/K+/2CI transport proteins in the loop of Henle
this causes a reduction in the reabsorption of sodium
which significantly increases diuresis (salt goes, water followers)
some pts may also lose too much potassium
so they may be on supplements of K+
What is a potassium sparing diuretic?
increases diuresis
without causing potassium to leave the body
What are thiazide diuretics?
act by inhibiting NaCl reabsorption into
the distal convoluted tubule of the kidney
This happens through the suppression of the sodium chloride cotransporter
**Mainly used to treat HTN, heart failure, kidney failure and diabetes
What is an antihyperlipidemic agent?
An antihyperlipidemic agent is
a medication used to lower levels of
lipids (fats) in the blood,
such as cholesterol and triglycerides
What are common suffixes in cholesterol meds?
“statin”
“fibrate”
“azole”
“nic acid”
