foreign so now we're going to go ahead and go over calcium channel blockers for another type of antihypertensive medication here let me move this over here out of the way all right so very very short little bit of information for calcium channel blockers is that they're primarily used for hypertension and angina or chest pains there um it causes the smooth muscle relaxation okay to occur so what we're actually seeing is this decrease in peripheral smooth muscle tone decrease the investular systemic vascular resistance which then leads to that decrease in blood pressure this leads to this this decrease in this blood pressure which is what we're looking for what's nice about these these will end in uh peen nifedipine amliodipine so these will end in the peen or sometimes just peen okay when you're looking at these so um they're great for Angina hypertension dysrhythmias migraine headaches raynon's disease um things like that so they can also um how they're going to work is they're going to block those calcium channel channels that are in there in the body so that causes that smooth muscle to then relax some adverse effects that kind of go along with them is a reflexive tachycardia so we can have where it relaxes so much that the body's like well wait a minute we need to make the heart rate beat a little faster orthostatic hypotension again which is a common one with all antihypertensives you have to be careful with this also can cause a dysrhythmia okay so something that we have to be concerned with with our patients that already have a pre-existing condition s that we're looking at with these would be um they can't take it with grapefruit juice it will make it more toxic and then it also cannot be taken with Verapamil or dilatism uh those are all things that they cannot be taking with that causes this toxicity and issues with that so those are some things that you need to know specifically for calcium channel blockers
