[Use of anti-hypertensive and anti-diabetic drugs by the elderly: a survey in Belo Horizonte, Minas Gerais State, Brazil].

Concern over the harmful effects of drug use by the elderly has motivated studies aimed at identifying problems in such utilization. This was a household survey with retirees aged > 60 years living in Belo Horizonte, Minas Gerais State, Brazil, in 2003, who reported having a diagnosis of diabetes and/or hypertension. Quality of anti-hypertensive and anti-diabetic medication was measured by redundancy, combinations of drugs, and inappropriate drugs. Among 283 elderly patients (89%) with self-reported hypertension and use of anti-hypertensive pharmacotherapy, 68.2% were using diuretics and 37.8% ACE inhibitors. Among the 22 (64.7%) self-reported diabetic patients under pharmacotherapy, 45.5% were using insulin and 77.3% oral anti-diabetic agents. Among the 89 self-reported diabetic and hypertensive patients, 80 (90%) were using anti-hypertensive drugs and 51 (57.3%) anti-diabetic agents. The study revealed the use of dose combinations, redundant use, and inappropriate medicines, thus indicating the need to monitor treatment protocols and improve healthcare for elderly patients.
