Monotherapy vs combination therapy for dyslipidemia in the elderly.

Dyslipidemia conveys a major increased risk of future cardiovascular events in older persons. Data from large randomized controlled trials confirm that statin therapy is as beneficial in older adults as it is in younger persons in both primary and secondary prevention. National guidelines support the use of statin therapy to reduce low-density lipoprotein cholesterol in older adults, with the recommended goal of <100 mg/dL in high-risk patients and an optional goal of <70 mg/dL in very high-risk patients. In the majority of high-risk older patients, these levels of low-density lipoprotein cholesterol can be achieved with initial low doses of an efficacious statin, but in some clinical situations, combination therapy may be considered. Moreover, statins appear to be safe and well tolerated in older age groups. Because of heightened risks of drug-drug interactions, the likelihood of polypharmacy in seniors, and issues of tolerability and convenience, monotherapy with low doses of an efficacious statin may be preferable to combination therapy in elderly individuals.
