Common patient medications Flashcards
what are calcium channel blockers used for
HTN, angina and arrhythmia
calcium channel blockers come in two types: name the main action of the ones ending in dipine
more potent towards the blood vessels than the heart, thus used to manage HTN most commonly
name some common calcium channel blockers
amlopdipine
felodipine
veraprimil
diltiazem
mechanism of calcium channel blockers
blocks voltage gated calcium channels in the cell, thus decreasing the amount of calcium entering the cell, thus cannot contract as frequently or forcefully
how calcium channel blockers treat HTN
vascular smooth muscle relaxes due to lack of calcium this reducing peripheral vascular resistance and BP
how calcium channel blockers treat angina
relaxes coronary vessels and reduces after load thus reducing 02 demand on the heart
how calcium channel blockers treat arrhythmia
decreases the depolarisation of pacemaker cells due to a lack of calcium within the cell, thus slowing the rate, inhibiting deregulator firing
interactions to be aware of with calcium channel blockers
if pt is on a calcium channel blocker and digoxin, risk of digoxin poising
mechanism of beta blockers
inhibit beta receptors so adrenaline and noradrenaline can’t bind, leading to an inhibition of SNS response including decreased HR, BP and contractility
name some examples of cardiac selective beta blockers
metoprolol, alenalol , esmolol
what is a statin
a cholesterol lowering medication
why is hyperlipedemia and why is it bad
an elevated level of fat in the bloodstream, which can lead too a buildup in the vessels (althlescrosis) caring heart attack or stroke
examples of statins
sminvastatin
atorvastatin
paravstatin
rosuvastatin
mechanism of statins
decreases the synthesis of cholesterol by inhibiting the formation in the liver, as well as up regulating the process of the liver removing cholesterol from the blood.
