When prescribing statins to older adults, heightened risk of drug interactions is a significant consideration. As individuals age, they often take multiple medications for various chronic conditions, which can increase the likelihood of interactions between statins and other drugs. Statins are metabolized in the liver, primarily through the cytochrome P450 enzyme system, which is also involved in the metabolism of many other medications. This can lead to either increased toxicity or reduced efficacy of statins when taken in conjunction with other drugs that induce or inhibit these metabolic pathways.

Older adults may also have altered pharmacokinetics due to physiological changes such as liver function decline or changes in body composition, making them more susceptible to the effects of concurrent medications. Therefore, a thorough review of a patient’s medication list and close monitoring for any potential interactions is crucial when considering statin therapy in this population.
