Antihypertensive Drugs Flashcards
Eprelenone indications
- HTN (Spironolactone is NOT indicated for HTN)
- Heart failure
- POST MYOCARDIAL INFACTION
Eprelenone
Aldosterone Antagonist
TerAZOSIN
Alpha blockers (antagonist)
Alpha blockers: MOA
Inhibit alpha-1 receptors, causing arteriole vasodilation
Alpha blockers: indications
- HTN
- BPH
Alpha blockers: adverse effects
- Orthostatic hypotension
- First dose syncope
- Fluid retention
- Increased risk of HF when used alone
AtenoLOL
B-blocker (antagonist)
MetoproLOL
B-blocker (antagonist)
PropranoLOL
B-blocker (antagonist)
TimoLOL
B-blocker (antagonist)
Nebivolol
B-blocker and vasodilator
Beta 1 selective at doses < or = to 10mg
Nebivolol
DoxAZOSIN
Alpha blockers (antagonist)
Labetalol
Alpha1 and NON SELECTIVE B-blockers
Carvedilol
Alpha1 and NON SELECTIVE B-blockers
B-blocker: MOA
Directly block adrenergic stimulation of B receptors
- Reduce CO by decreasing heart rate (negative chronotropic effect) and contractility (negative inotropic effect)
- Negative dromotropic effect
- Inhibits renin secretion
Metoprolol XL
Cardivolol
Visoprolol
B-blockers indicated for heart failure
B-blocker indications
- Ischemic heart diseas (stable/unstable angina, MI)
- HF
- HTN
DO NOT STOP ABRUPTLY
B-blockers: adverse effects
- bradycardia
- heart block (contraindicated in 2nd and 3rd degree)
- fatigue, lethargy
- hypotension
- bronchoconstriction (CAUTION IN ASTHMA, USE SELECTIVE B-BLOCKERS)
- may mask signs of hypoglycemia
B-blockers w/ NSAIDs
decrease antihypertensive effects of B-blockers
Clonidine
Central-acting alpha-2 agonist
Clonidine MOA
Directly stimulate pre-synaptic alpha-2 receptors in the brainstem (reduce sympathetic outflow)
Clonidine: indication
HTN
Beta 1 selective
- Atenolol
- Metoprolol
- Bisoprolol
Sedation Fatigue Dry Mouth Depression REBOUND HYPERTENSION (DO NOT STOP ABRUPTLY)
Clonidine adverse effect
(central acting alpha-2 agonist
BenazePRIL
Angiotensin Converting Enzyme Inhibitor (ACEIs)
CaptoPRIL
Angiotensin Converting Enzyme Inhibitor (ACEIs)
EnalaPRIL
Angiotensin Converting Enzyme Inhibitor (ACEIs)
LisinoPRIL
Angiotensin Converting Enzyme Inhibitor (ACEIs)
Clonidine interaction
Mirtazapine decreases antihypertensive effect
Dry, non-productive cough
ACEI adverse effect
RamiPRIL
Angiotensin Converting Enzyme Inhibitor (ACEIs)
Indicated for HTN (coexisting diabetes, chronic kidney disease, MI, or HF)
HF
Chronic Kidney Disease
ACEIs
Adverse effects of both ACEIs and ARBs
- Hypotension
- Hypokalemia
- Contraindicated in pregnant patients
- Contraindicated in patients w/ bilateral renal artery stenosis
Precaution in hypovolemia or dehydration
ACEI adverse effect
QuinaPRIL
Angiotensin Converting Enzyme Inhibitor (ACEIs)
Less likely to cause angioedema and cough

Olmesartan
Losartan
Angiotensin II Receptor Blockers (ARBs)
Valsartan
Angiotensin II Receptor Blockers (ARBs)
Candasartan
Angiotensin II Receptor Blockers (ARBs)
Olmesartan
Angiotensin II Receptor Blockers (ARBs)
Irbesartan
Angiotensin II Receptor Blockers (ARBs)
Aliskiren
Direct renin inhibitor
Aliskiren MOA
results in blockade of conversion of Angiotensinogen to Angiotensin I
Aliskiren: indication
HTN
Aliskiren: adverse effects
- hyperkalemia
- angioedema (less than ACEIs)
- hypotension
- hyperuricemia
Aliskiren w/ ARBs/ACEIs in patient w/ diabetes
contraindicated because of risk of renal impairment (GFR<60), hypotension, and hyperkalemia
Hydralazine
direct vasodilator
Hydralazine MOA
directly relaxes arterial smooth muscle
Hydralazine in combination w/ isosorbide is indicated for…?
