Q

What are medication food interactions of HMG CoA inhibitors

A

Fibrates ( gemifibrozil, fenofibrate) and ezetimibe ( Zetia) increase the risk of myopathy.
Medications that supress CYP3A4 such as erythromycin and ketoconazole can increase levels of statins when taken concurrently.

Q

What are medication food interactions of ezetimibe ( Zetia)

A

Bile- acid sequestrants, such as cholestyramine interfere with absorption.(advise ppl to take ezetimibe 1 hr before or 4 hr after taking bile sequestrants)
Statins such as atorvastatin can increase the risk of liver dysfunction and or myopathy.
Concurrent use with Fibrates such as gemifibrozil, increases the risk of cholelithiasis and myopathy
Levels of ezetimibe can be increased with concurrent use of cyclosporine.

19
Q

What are bile acid sequestrants

A

Meds that decrease LDL cholesterol

It is used as an adjunct with a HMG CoA reductase inhibitor, such as atorvastatin and with dietary measures to lower cholesterol levels.

20
Q

What is the prototype drug of bile acid sequestrants

A
colesevelam HCL ( Welchol)
colestipol ( Colestid)
21
Q

What are adverse effects of bile acid sequestrants

A

Constipation increase intake of high fiber foods

22
Q

What are contraindications and precautions of bile acid sequestrants

A

colesevelam is pregnancy category B
colestipol is pregnancy category C

Colesevelam is contraindicated in pancreatitis caused by high triglycerides and in bowel obstruction
Use cautiously in clients who have billary disorders, diabetes mellitus and in older ppl.

23
Q

As an oral tablet that should not be crushed or chewed Give 30 min before meals It is also given in powder formulation.
25
What is nicotinic acid, niacin ( niacin, niaspan)
Nicotinic acid and niacin decrease LDL and triglyceride levels. They are used for ppl at risk for pancreatitis and elevated triglyceride levels and LDL niacin raises HDL levels.
26
What are complications of nicotinic acid and niacin
``` GI distress Facial flushing and feeling of warmth, tingling in hands and feet Hyperglycemia Hepatotoxicity Hyperuricemia ```
27
What should be administered if a persons URIC acid level is elevated
Allopurinol
28
Nicotinic acid and niacin are contraindicated in who
Ppl with liver disease and gout
29
What are prototype drugs of Fibrates
Gemifibrozil ( Lopid) | Fenofibrate ( Tricor, Lofibra)
30
What is the expected action of Fibrates
It reduces plasma triglycerides | Increases levels of HDL
31
What are adverse effects of Fibrates Gemifibrozil ( Lopid,) fenofibrate ( Tricor, Lofibra)
GI distress Gallstones Myopathy Hepatoxicity
32
What are indications of gallbladder disease
RUQ pain Fat intolerance Bloating
33
When administering Fibrates and the client c/o myopathy, what should the nurse do
Obtain baseline creatine kinase ( CK) level, monitor periodically Stop med if CK levels are elevated
34
What drugs are contraindicated with Fibrates
Concurrent use with warfarin increases the risk of bleeding | Statins increase the risk of myopathy
35
How should Fibrates be administered
Orally | Advise clients to take med 30 min prior to breakfast and dinner

Jaundice as this is a sign of hepatoxicity | Jaundice, anorexia, and upper abdominal discomfort may be findings in liver impairment
38
What are teaching of a person taking digoxin and Colesevalam

In ppl with a active moderate to severe liver disorder, especially if the client is taking a statin such as simvastatin
40
When administering niacin, what adverse effects should be Monitored for?
Hyperglycemia Flushing of the skin Jaundice
41
What are direct renin inhibitors and the prototype drug of this class
Binds with renin to inhibit the production of angiotensin I, thus decreasing the production of angiotensin II and aldosterone By doing this, hypertension is relieved. This med can be used alone or with other aniptihypertensive meds Prototype drug; aliskiren ( Tekturna)
42
What are adverse effects of direct renin inhibitors | Aliskiren ( Tekturna)
