Pharmacotherapeutics in the elderly

Drugs are the most cost-effective modality of chronic care, and older adults with multiple illnesses often need multiple drugs. Because this may lead to drug interactions, adverse drug effects, and problems with compliance, drug regimens should be individualized and as few drugs as possible used. When a new drug is indicated, it is important for the physician reassess the appropriateness and continued need for the existing regimen. Patients and providers must agree on a particular regimen, its goals, promises, and limitations.
