Cards

Term
What are the medications for hyperlipidemia?
Definition
1) HMG-CoA reductase Inhibitors (STATINS-Lipitor, Zocor) 2) Fibric Acid Derivatives (Lopid, Tricor) 3) Bile Acid Sequestrants (Questran, Welchol) 4) Nicotinic Acid (Niacin, VitB3) 5) Ezetimibe (Zetia)
Term
What do Statins do? How do they work?
Definition
Reduce LDL, raise HDL. They inhibit the enzyme HMG-coA reductase, in the liver that synthesizes cholesterol.
Term
What are beneficial side effects of Statins?
Definition
mild vasodilation, stabilization or atherosclerotic plaques, decreased risk of thrombotic events, systemic decrease of inflammation
Term
At what time of day do we give Statins and why?
Definition
At night, most cholesterol synthesis occurs at night.
Term
What are the 2 ADRs of Statins?
Definition
1) Myopathy/rhabdomyolysis. Monitor for muscle pain and eval CK. May lead to renal tube damage. 2) Hepatotoxicity. Baseline LFT required before admin and Q6months
Term
What do Fibric Acid Derivatives do?
Definition
Inc HDL. Inc r/f gallstone. ADR=myopathy &hepatotoxicity. Contraindicated with warfarin, statins and bile acid seqs.
Term
What do Bile Acid Sequestrants do? Where do they act?
Definition
Eliminate bile, so live has to produce more, a process that requires cholesterol. Act only in GI so side effects include bloating, constipation & GI binding w/ other Rx
Term
What does Nicotinic Acid do?
Definition
Dec LDL & TG, Inc HDL. Causes intense FLUSHING. Hepatotoxic.
Term
What does Ezetimibe do?
Definition
Inhibits chol absorption. Can be used w/ other chol drugs.
Term
Which drugs treat HTN?
Definition
Diuretics, ACE inhib, ARBs, B blockers, Ca blockers, Vasodilators
Term
What are Diuretics MOA on HTN? Which diuretics are used?
Definition
reduces vol and promote vasodilation. Thiazide (Hydroclorothiazide) is most common. Loop (furosemide/Lasix) for greatest effect. K sparing (Spironolactone) aldosterone antagonist causing H20 & Na retention
Term
What are some Ace Inhibs and their MOA?
Definition
The "Prils." Reduce angiontesin II thus aldosterone stimulation resulting in vasodilation and dec blood vol.
Term
Why would a person take an ACE inhib?
Definition
HTN, heart fail, AMI, non/diabetic neuropathy, prevent MI & stroke mortality
Term
What are Ace Inhib side effects?
Definition
COUGH!!! 1st dose hypotension. Hyperkalemia. Proteinuria
Term
What's an ARB?
Definition
2nd gen ACE inhib (Diovan). Does not cause cough and hyperkalemia
Term
What is the Ca blocker MOA and use?
Definition
(Procardia, Cardizem) Vasodilate by preventing Ca to enter cells, thus blocking smooth muscle contraction in arteries/arterioles. Blocks SA/AV node firing, and blocks contractility.
USED for HTN, slows tachycardia or arrhythmias, angina
Term
What are Ca blocker side effects?
Definition
Orthostatic hypotension. Constipations. Vasodilation=facial flushing, ankle edema, HA. Bradycardia
Term
B blockers (olols) action, use and side effect.
Definition
vasodilate and lower HR. Treats HTN, angina related to CAD. Side effects are hypotension, dizziness, exercise intolerance, bronchospasm (DONT give to asthmatics)
Term
Vasodilator (Hydralazine, Minipress, Nirpride) MAO, use and side effects.
Definition
selectively dilates arterioles. Treats HTN, cardiac failure. Side effects are reflex tachycardia, inc contractility (prevent w/ b blocker), hypotension, reflex volume retention (prevent w/ diuretic), & SLE symptoms
Term
Anti-HTN general side effects?
Definition
Hypotension, fatigue, weakness, lethargy, sexual dysfunct, B blockers intensify asthma and slow heart rhythm, changes in K levels, reflex tachycardia, reduced CO
Term
Other than drugs, what can you do for HTN?
Definition
Improve diet, exercise, limit Na, avoid tobacco and better select your parents!
Term
What are the "other" anto-HTN Rx's?
Definition
Clonidine-centrally acting sympathetic inhib * Proazosin hydrochloride (minipress)-alpha blocking agents that dilate both veins and arteries
