Anti-Hypertensive Drugs Flashcards
ACE Inhibitors Indication
- first line for HTN in patients with CHF or DM
2. post-MI
ACE Inhibitors MOA
- blocks conversion of angiotensin I to angiotensin II –> less vasoconstriction
- increases bradykinin levels in order to vasodilate
ACE Inhibitors Examples
- Lisinopril (prinivil/zestril)
- Benazepril (lotensin)
- Quinapril (accupril)
ACE Inhibitors CI
- Pregnancy, category D
- Renal artery stenosis
- caution with renal impairment
ACE Inhibitors SE
- DRY COUGH (due to bradykinins)
- Hyperkalemia!!!
- Hypotension
- Renal dysfunction
- Angioedema!!!
Benefits of ACE Inhibitors in diabetic patients
- delays onset of diabetic neuropathy
2. renal protection
ACE Inhibitors special considerations
- they decreases absorption of antacids (pepcid, zantac) - separate time of dosing
- check K and creatinine levels (CMP or BMP)
ARBs MOA
blocks angiotensin II’s binding/effects on blood vessels –> decreases vasoconstriction, increases vasodilation
ARBs Indications
HTN, second line for CHF patients if cannot tolerate
ARBs CI
- pregnancy, category D
2. renal artery stenosis?
ARBs SE
- dizziness, hypotension
- hyperkalemia
- renal failure
- angioedema (less than ACE)
but overall well tolerated
ARBs Examples
- Losartan (cozaar)
- Valsartan (Diovan)
- Irbesartan (Avapro) - stronger than losartan
Candesartan used for BP and headache
Beta Blockers MOA
bind beta adrenoceptors and block binding of NE and E which inhibits sympathetic effects –> slow HR and decrease BP
3 types of Beta Blockers
- Cardioselective - affect beta 1 on heart only
- Non-selective - affect beta 1 and beta 2 (lungs) equally
- Mixed alpha and beta
Cardioselective Beta Blockers examples
- metoprolol (lopressor/toprol)
2. atenolol (tenormin)
Non-selective Beta Blockers examples
- propranolol (inderal)
2. nadolol
mixed alpha and beta blockers example
- carvedilol/coreg (use for stable CHF)
2. labetalol (use in pregnancy, preeclampsia)
Beta Blockers Cardiac Indications
- CHRONIC CHF
- A fib/A flutter/other tachyarrhythmias
- angina
- HTN (3rd line)
- post-MI (decreases O2 requirement)
Beta Blockers Non-cardiac indications
- migraine prophylaxis
- anxiety, public speaking
- tremors
- timolol (nonselective) –> glaucoma
Beta Blockers CI
- Asthmatics, COPD for non-selective
- 2nd/3rd degree heart block
- bradycardia
- sick sinus syndrome
- ACUTE heart failure
- severe hypotension
- caution with diabetics!
- Raynauds
Beta Blockers S/E
- Hypotension
- asthma/bronchoconstriction
- Raynauds
- impotence
- fatigue (MC)
- MASK SYMPTOMS OF HYPOGLYCEMIA
- insomnia
- depression
- nightmares
- increased triglycerides, decreased HDL - monitor lipids
Calcium Channel blockers types
- Dihydropyridines
2. Non-dihydropyridines
Dihydropyridines examples
- amlodipine/norsac
2. nifedipine/procardia
What medication is good for African Americans
Calcium Channel blockers - Dihydropyridines
Dihydropyridines indications
- HTN
- diastolic heart failure
- prevention/tx of coronary spasms (prinzmetal angina, cocaine induced MI)
Dihydropyridines CI
- pregnancy
- conditions that worsen with tachycardia (CAD, aortic stenosis, mitral stenosis)
- Do not take with grapefruit juice
Dihydropyridines SE
- flushing
- dizziness
- headache - cerebral vasodilation
- tachycardia
- constipation
