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
|
Definition
Inhibits chol absorption. Can be used w/ other chol drugs. |
|
|
Term
|
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
|
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 |
|
