title: Drug and nutrient interactions in the elderly diabetic.
abstract: Elderly diabetics take more drugs than other groups of elderly patients. Their multiple drug use is largely explained by the drugs that they take for complications of their primary disease; these include cardiovascular drugs for macrovascular disease and antibiotics for secondary infections. They also take more drugs for control of other conditions that are etiologically associated with the development and progression of their diabetes, including antihypertensive agents, antilipemic agents and steroids, and nonsteroidal antiinflammatory drugs (NSAIDs), which are taken for relief of joint pain that is intensified by arthritic joints bearing excess weight. Drugs taken by elderly diabetics that contribute to the high prevalence of drug-nutrient interactions include those taken as antidiabetic agents, including both insulin and sulfonylureas as well as calcium channel blockers; they also include thiazides, loop diuretics, sulfa drugs, cephalosporin antibiotics, tetracyclines, antifungal agents, cholestyramine and colestipol, niacin, prednisone and other corticosteroids, and NSAIDs. These drugs and drug combinations contribute to the risk of hyperglycemia, which can cause nonketotic hyperglycemia in the elderly; to the risk of hypoglycemia, which in the elderly carries the risk of inducing pseudo-stroke; to the risk of drug-induced nutritional deficiencies from antilipemics and cephalosporins, which can induce vitamin K deficiency; to the risk of acute incompatibility reactions, including flush reactions from chlorpropamide, niacin, and calcium channel blockers; and to the risk of edema, anemia, and hyperkalemia from NSAIDs.(ABSTRACT TRUNCATED AT 250 WORDS)
