Study Notes
Atorvastatin Overview
- Brand name for Atorvastatin is Lipitor.
- Atorvastatin belongs to the class of drugs known as HMG-CoA reductase inhibitors (statins).
Indications
- Used for treating hypercholesterolemia and reducing cardiovascular events in high-risk individuals.
- Achieves an 18-55% decrease in LDL cholesterol and a 5-15% increase in HDL cholesterol.
- Reduces triglycerides by 7-30%.
Mechanism of Action
- Atorvastatin inhibits the HMG-CoA reductase enzyme, essential for cholesterol synthesis in the liver.
Pharmacokinetics
- Metabolized in the liver and excreted predominantly via feces (80-85%) with some elimination in urine.
Dosage
- Oral dosage typically ranges from 10-80 mg daily as a single dose.
Side Effects
- Potentially severe side effects include myopathy and rhabdomyolysis, which may lead to muscle damage and kidney issues.
- Common side effects: muscle pain, nausea, constipation, abdominal discomfort, diarrhea, headache, and skin rash.
Monitoring and Nursing Implications
- Monitor for severe muscle symptoms, fatigue, or cola-colored urine indicating possible rhabdomyolysis.
- Caution is warranted in aging individuals and those on high doses or with concurrent drug interactions (CYP3A4 inhibitors).
- Liver function tests should be routinely conducted due to inhibition of HMG-CoA reductase.
Contraindications
- Contraindicated in pregnancy, lactation, active liver disease, unexplained serum enzyme elevations, and hypersensitivity.
Use in Special Populations
- Atorvastatin is first-line for dyslipidemia in children after lifestyle changes.
- Recommended for older adults when lifestyle modifications are insufficient for lowering LDL cholesterol.
- Safe in renal impairment without dosage adjustment; caution in hepatic impairment due to the risk of accumulation.
Efficacy and Onset
- Begins to show effects within 1-2 weeks, with peak efficacy typically occurring in 4-6 weeks.
Home Care Considerations
- Regular liver function tests and lipid profile assessments are essential for ongoing management in home care settings.
