Flashcards
Statins
Statins
Drugs like atorvastatin, simvastatin, and lovastatin that lower cholesterol levels by blocking the enzyme HMG Co-A Reductase, which is responsible for cholesterol production.
Myopathy
Myopathy
A condition characterized by muscle pain, weakness, and potential breakdown, which can be a serious side effect of statin medications. It can lead to rhabdomyolysis, impacting kidney function.
Rhabdomyolysis
Rhabdomyolysis
A dangerous condition caused by the breakdown of muscle tissue, releasing myoglobin into the bloodstream, which can damage the kidneys. It can occur as a serious side effect of statins.

Study Notes
Statin Medications
- Statins are a class of drugs used to lower cholesterol
- Drug names end in "-statin", examples include Lovastatin, Simvastatin, Rosuvastatin, Atorvastatin, and Pravastatin
- Nystatin is an antifungal agent, not a statin
Clinical Use
- Statins lower cholesterol levels, reducing risk of heart attack and stroke
- Treat cardiovascular conditions such as coronary artery disease and blood clots
Mechanism of Action
- Statins decrease cholesterol production by inhibiting the enzyme HMG Co-A Reductase
- Lowering LDL ("bad" cholesterol)
- Increasing HDL ("good" cholesterol)
- Reducing triglycerides
Side Effects
- Liver Damage (Hepatotoxicity): Regular monitoring is essential
- Myopathy (Muscle Pain): Muscle pain/aches, weakness or increased CK levels requires immediate reporting and adjustments to the treatment
- Rhabdomyolysis Risk: Muscle breakdown and kidney damage, a serious complication
- Gastrointestinal Issues: Nausea, vomiting, diarrhea, constipation, or abdominal cramping are possible side effects
- Other: Headache, rash, and other symptoms.
Contraindications
- Pregnancy: Statins are contraindicated (Pregnancy Risk Category X) due to teratogenic potential
Nursing Considerations
- Grapefruit Juice Interaction: Avoid grapefruit juice to prevent potentially elevated side effects
- Best Time to Take: Administer at night to align with peak cholesterol synthesis during the overnight fasting state
