From the Guidelines
Low intensity statins are recommended for patients who need modest LDL cholesterol reduction (less than 30%), have a lower cardiovascular risk profile, are elderly, or cannot tolerate higher statin doses due to muscle pain or other side effects, with options including pravastatin (10-20 mg daily), simvastatin (10 mg daily), lovastatin (20 mg daily), fluvastatin (20-40 mg daily), and pitavastatin (1 mg daily) 1.
Key Points
- Low intensity statins work by inhibiting HMG-CoA reductase, the enzyme responsible for cholesterol production in the liver, but at a less potent level than moderate or high intensity regimens.
- They should be taken consistently, usually once daily, often in the evening since cholesterol production peaks overnight.
- Regular monitoring of lipid levels and liver function is recommended, typically 4-12 weeks after starting therapy and then annually.
- While low intensity statins provide less LDL reduction than higher doses, they still offer significant cardiovascular protection with fewer adverse effects, making them appropriate for many patients who need cholesterol management.
Considerations
- The choice of low intensity statin should be based on the individual patient's needs and medical history, as well as the potential for drug interactions and side effects.
- Patients should be educated on the importance of adherence to their medication regimen and lifestyle modifications to maximize the benefits of low intensity statin therapy.
- Healthcare providers should regularly assess patients' response to low intensity statin therapy and adjust treatment as needed to achieve optimal cardiovascular risk reduction.
Evidence
- The 2018 AHA/ACC/AACVPR/AAPA/ABC/ACPM/ADA/AGS/APhA/ASPC/NLA/PCNA guideline on the management of blood cholesterol recommends low intensity statin therapy for patients who require modest LDL-C reduction 1.
- Clinical trials have demonstrated the efficacy and safety of low intensity statins in reducing cardiovascular risk, with a meta-analysis showing a 22% reduction in ASCVD risk for each 39-mg/dL reduction in LDL-C 1.

From the Research
Low Intensity Statins
- Low intensity statins are often used in combination with other medications, such as ezetimibe, to treat hypercholesterolemia 2, 3, 4, 5, 6
- Studies have shown that combination therapy with ezetimibe and statins can be more effective in reducing LDL-C levels than statin monotherapy 3, 5
- The efficacy and safety of coadministration of ezetimibe and statins have been demonstrated in various patient populations, including women and men 4, elderly patients 6, and patients with diabetes 3
- The combination of ezetimibe and statins has been shown to be well tolerated, with a similar incidence of adverse events and serious adverse events compared to statin therapy alone 2, 6
- Subgroup analyses have suggested that the beneficial effects of ezetimibe plus statin on LDL-C, triglycerides, and HDL-C are independent of age groupings 6 and geographic location 5
- The ability to reduce cholesterol levels of combination therapy with ezetimibe and different statins may vary, with some studies suggesting that the combination of ezetimibe and atorvastatin or simvastatin may be more effective than the combination of ezetimibe and rosuvastatin 5
