Blood Pressure Drugs | Pharmacology

hi rod dr. Mike here in this video we're going to go through a really quick and easy way to remember blood pressure medications so what you need to know is this a B C and D now a stands for two types of anti hypertensive meds the first one you need to know is angiotensin converting enzyme also known as ACE inhibitors the second type of star today also is angiotensin but this is angiotensin ii receptor blockers so they're the two that start with a that you need to remember for B we've got beta blockers for C we have calcium channel blockers also known as long lasting calcium channel blockers and for D we have diuretics and there's many different types of diuretics but diuretics but when we look at the direct use as antihypertensives were specifically referring to the thiazide diuretics or thiazide like diuretics alright so this is the quick and easy way to remember the mainstay anti hypertensive medications but how do you remember the types of meds that sit within each of these categories well for example when we look at the ACE inhibitors what you'll find is a lot of them and in pril so a lot of the meds have the suffix pril when we look at angiotensin ii receptor blockers a lot of the meds have the suffix Sartain when we look at beta blockers a lot of the meds have the suffix lowell when we look at Kelsey channel blockers a lot of the meds have the suffix dipping or Die pain and then the thiazide diuretics or diuretics while they're a bit tricky they're more variable but often they end in thiazide but there are others that do not end in thiazide now very quickly how do these blood pressure medications work well you need to know the blood pressure equation blood pressure equals cardiac output times systemic vascular resistance also known as total peripheral resistance what are these different things well cardiac output is also known as heart rate times stroke volume and systemic vascular resistance is the diameter of blood vessels okay so ACE inhibitors stop the production of angiotensin ii angiotensin ii does a bunch of things one thing that it does is it vasoconstrict so it stops this therefore stopping systemic vascular resistance from increasing stops blood pressure from increasing but it also stops blood volume increasing that has to do with stroke volume in addition to that angiotensin ii receptor blockers work similarly stopping those two beta blockers stop the heart rate from beating so fast so it's stopping heart rate here calcium channel blockers stop the heart from beating so hard this has to do with stroke volume as well double cross and diuretics reduce the amount of circulating fluid within the body this also has to do with stroke volume as well as you can see all of these anti hypertensive medications affect the blood pressure equation at some point therefore affecting blood pressure and hopefully dropping it so that's a nice quick and easy way to remember your antihypertensives
