Anti-Hypertensives Flashcards
1
Q
Different Categories of Antihypertensive Drugs
A
- alpha and beta blockers
- calcium channel blockers (CCbs)
- ACE-Inhibitors
- ARBs
- Diuretics (will cover in its own set of cards)
2
Q
Beta Blocking Agents
A
- decrease cardiac outputs and inhibit renin secretion, which results in lowering of BP
- work by inhibiting beta receptors by competing with catecholamines at the receptor site located on membrane of the cardiac muscle (basically decreases heart function and vascular resistance)
- Prototype Beta Blocker in this case is Inderal
3
Q
Inderal
A
- lipid soluble beta blocker, therefore having a large distribution within the body
- side effects include basic side effects that occur from slowing down of the body like decreased heart function, drowsiness, n/v, depression, etc.
- interacts negatively with anti diabetics, CCbs, cocaine, xanthines, and MAO inhibitors (DEAR GOD DO NOT USE THESE TOGETHER EVARRRR)
- can cause withdrawl
4
Q
Inderal Patient Education
A
- take own pulse, if under 60 bpm withhold med
- dont take otc
- caution about orthostatic changes and rapid movements
- dont operate car or machinery until adjusted to med
5
Q
Alpha Adrenergic blocking agents
A
- main drug is prazosin
- dilate arterioles and veins causing decreased pulmonary vascular resistance
- side effects include no known drug interactions, and they can increase fluid retention
- monitor BP and orthostatic changes
- 1st dose is to be taken at bed time
- make sure to instruct client about potential side effects, including POSSIBLE SEXUAL PERFORMANCE ISSUES
6
Q
ACE Inhibitors
A
- block angiotensin I converting enzyme needed for conversion to angiotensin II (a powerful vasoconstrictor) and therefor can cause relief from hypertension
- good for young and middle aged clients with hypertension, and in combintation with diuretics are also good for the elderly and african americans
- does not effect lipid profiles
- is cardio protective
- prototype drug is capoten (captopril)
7
Q
Ace Inhibitor Side Effects and Interactions
A
- side effects include dry cough, HA, diarrhea, loss of taste, weakness, nausea, dizziness, rash, fever, joint pain
- DEAR GOD DO NOT USE IF PREGNANT
- react negatively with alcohol, diuretics, and potassium sparing diuretics
8
Q
ACE Inhibitor Patient Education
A
- Make sure to monitor WBCs, Proteinuria, and elevated K levels
- full drug effect takes several weeks
- report side effects promptly
- be cautious with physical activity
- do not use K supplements
- report signs of infection or easy bruising or bleeding
9
Q
Calcium Channel Blockers (CCbs)
A
- cause reduction in the force of myocardial contraction by blocking CA++ ion flow, less muscle excitation, and prolonged AV refractory time
- used to treat angina, hypertension, Raynauds, arryhthmias, and vascular headache
- med to focus on is Verapamil (calan)
- in the elderly monitor response to drug closely especially dizziness and orthostatic changes
- check with prescriber before using with nitroglycerine
10
Q
Carvedilol
A
- a combination alpha and beta blocker
