    Study Notes

    Antihyperlipidemic & Vasodilators

    • Lipoproteins Review:
      • High-density lipoprotein (HDL) is healthy; it removes cholesterol from the blood and transports it to the liver for elimination.
      • Low-density lipoprotein (LDL) is lethal; it contains a high percentage of cholesterol.
      • Very low-density lipoprotein (VLDL) contains mostly triglycerides and less cholesterol.
      • Chylomicrons contain mostly triglycerides and transport fatty acids and cholesterol to the liver.

    Nonpharmacologic Methods for Cholesterol Reduction

    • Reduce saturated fats and cholesterol in the diet.
    • Reduce total fat intake to 30% or less of caloric intake.
    • Reduce cholesterol intake to 300 mg/day or less.
    • Exercise.
    • Stop smoking.

    Types of Antilipidemics

    • Statins (HMG-CoA reductase inhibitors): Inhibit the enzyme HMG CoA reductase, reducing cholesterol synthesis. Decreases LDLs and increases HDLs.
    • Bile-acid sequestrants
    • Fibrates (fibric acid)
    • Nicotinic acid
    • Cholesterol absorption inhibitor

    HMG-CoA Reductase Inhibitors (Statins)

    • Uses: Hyperlipidemia (high cholesterol).
    • Action: Inhibit the enzyme HMG CoA reductase in cholesterol biosynthesis. Decreases LDLs, increases HDLs.
    • Side Effects:
      • Rare to have side effects; includes GI issues, headache, photosensitivity, cataracts, liver impairment, hyperglycemia, and rhabdomyolysis (skeletal muscle disorder).
    • Contraindications:
      • Active liver disease
      • Pregnancy
    • Caution:
      • History of liver disease
      • Alcohol use
    • Interactions:
      • Antacids

    Nursing Process: Statins

    • Assessment:
      • Assess vital signs and baseline serum cholesterol levels.
      • Assess liver function.
      • Obtain a medical/medication history.
      • Pregnancy test.
    • Nursing Interventions/Teaching:
      • Monitor the client's blood lipid levels and liver function.
      • Observe for signs/symptoms of GI upset.
      • Report unexplained muscle tenderness, weakness, fever, and malaise.
      • Inform the client that it may take several weeks or months for blood lipid levels to decline, and the importance of medication compliance.
      • Advise the client to take the medication at bedtime.
      • Advise the client on a low-fat/low-cholesterol diet.
      • Instruct the client to have annual eye examinations and report changes in visual acuity.
      • Do not stop the medication abruptly.

    Peripheral Vascular Disease

    • Causes: Arteriosclerosis, hyperlipidemia.
    • Signs/Symptoms: Numbness, coolness, and pain in extremities; claudication, leg ulcers.
    • Treatment: Peripheral vasodilators like cilostazol to increase blood flow.

    Drugs to Improve Peripheral Blood Flow - Cilostazol

    • Action: Causes peripheral vasodilation; inhibits platelet aggregation (weakly).
    • Use: Intermittent claudication and other peripheral vascular diseases.
    • Side effects: Dizziness, headache, GI distress, peripheral edema, tachycardia, palpitations, possible bleeding, and orthostatic hypotension.
    • Contraindications: Severe heart failure, bleeding disorders, and liver/renal disease (use with caution).
    • Interactions: Other drugs that cause vasodilation or bleeding, grapefruit juice.
    • Nursing Process:
      • Assessment: Obtain baseline vital signs, assess for signs of inadequate blood flow to extremities, and obtain medication/medical history.
    • Nursing Interventions:
      • Monitor vital signs (especially blood pressure and heart rate).
      • Inform clients that a desired therapeutic response may take 1.5-3 months.
      • Advise clients not to smoke or ingest alcohol.
      • Encourage clients to change positions slowly.
      • Take with food, not with grapefruit juice.

    Practice Questions

    • Practice Question #1: A client's serum lipids (cholesterol, LDL, HDL) are slightly outside the desirable range.
    • Practice Question #2: Rhabdomyolysis is a serious adverse reaction to atorvastatin calcium.
    • Practice Question #3: Cilostazol is an antiplatelet drug for peripheral vascular disease.
    • Practice Question #4: Ginkgo biloba is a commonly used herb for intermittent claudication, though it's not FDA-approved.
