I
Blood pressure A: Block ACE from converting A: COUGH, Angioedema,
A1 to A2 = LOWER BP Hyperkalemia
ACE “PRIL”
Catopril (capoten) T: Take on empty stomach
Decreases aldosterone production
Inhibitors Increases potassium
NSAIDS reduce med
Lisinopril (Zestil) Loses sodium and fluid
No bananas, avocados,
kiwi, cashews, green leafy
Decrease effectiveness
salt substitutes bc they

birth control
T: HTN, CHF, DM Neuropathy Use CAUTIOUSLY pt
severe CHF clients
Blood pressure A: Bind with A2 receptors, A: Hypotensive effects,
“SARTAN” block vasoconstriction GI Sensitivity
Angiotensin
Losartan aldosterone = LOWER BP T: Use CAUTIOUSLY with hepatic

birth control T: HTN, DM Nephropathy effectiveness
Blood pressure Alpha Blocker = “ZOSIN” A: Block alpha 1 or 2 in A: CNS effects, GI effects,
Prazosin (mini-press) heart = LOWER BP Hypotension, Edema
Doxazosin (cardura)
Sympathetic Misc: Alpha 1 or 2; Alpha 2 no
Nervous T: HTN, BPH ending; Clonidine (Catapres)
System
Beta blocker = “OLOL”
metoprolol (Lopressor) A: Block Beta cells in smooth A: CNS effects, Cardiac effects,
Bronchospasm, Hyperglycemia **
Blockers
atenolol (Tenormin)
muscle of heart = LOWER BP MASK SYMPTOMS OF
HYPOGLYCEMIA
“A” or “I” before LOL
(Alpha/Beta) labetalol (Trandate) T: First dose effect= ONLY FOR 2 weeks
-
carvedilol (Coreg) T: HTN, Tachycardia, Angina Use CAUTIOUSLY in COPD pt
V-erapamil
verapamil arrhythmia’s, Angina, N-ifedipine
Promotes oxygenation D-iltiazem
A: Act on smooth muscle to A: Related to change in BP, GI upset, Cyanide
Blood pressure toxicity, SUPER HYPOTENSIVE
“No ending” create muscle relaxation =
nitroprusside LOWER BP T: Use CAUTIOUSLY in pt with CAD, CHF, Tachycardia,
PVD
Vasodilators & **Used for severe hypertension

A: Medication binds to bile acids (high in cholesterol) in the A: Headache, fatigue, & drowsiness
Cholesterol intestines Direct GI irritation- nausea, increased bleeding
Insoluble complex forms & is excreted in feces times
Therefore, by the liver metabolizing the cholesterol to Vitamin A & D DEFICIENCIES need Ca for Vit D to
(Resins) INCREASE production of BILE ACIDS the BLOOD be absorbed
Bile Acid Choletyramine CHOLESTEROL LOWERS *DO NOT give to pts with complete biliary
obstruction
Sequestrates Colestipol (colestid) *Decrease effectiveness of DIGOXIN, WARFARIN,
THYROID HORMONES, THIAZIDE DIURETICS &
Colesevelam (Welchol) T: Reduces elevated serum cholesterol levels CORTICOSTEROIDS
Hypercholesterolemia
Pruritus (associated with partial biliary obstruction)
ONLY LOWERS LDL
A: HMG-CoA is an enzyme that is a catalyst during the GI Symptoms: flatulence, abdominal pain, cramps, nausea,
Cholesterol manufacturing of cholesterol vomiting, & constipation
“STATIN” These drugs block the enzyme therefore blocking the CNS: Headache, dizziness, blurred vision, insomnia, fatigue
Liver failure
synthesis of cholesterol
HMG-COA Atorvastatin (Lipitor) Report signs of myopathy leads to
RHABDOMYOLYSIS (breakdown of myoglobin muscle tissue
Reductase Pravastatin (Pravachol) release into blood can damage kidneys)
DO NOT give to anyone with active liver disease
Inhibitors Simvastatin (Zocor) CAUTIOUS for people with alcohol abuse tendencies
T: Watch for ASCITES/LIVER FAILURE
*LOWERS LDL Report muscle pain/weakness to HCP
Do NOT take with GRAPEFRUIT juice
*RAISES HDL
Take with a meal 5-7pm
Hyperlipidemia Continue med even when feeling better
High Triglyceride levels GET LIVER FUNCTION TEST
Primary prevention of coronary events Increase risk for digoxin/warfarin toxicity
