DIAZ-SOTO, María Teresa et al. The consumption of medicines in elderly patients. Rev cubana med [online]. 2021, vol.60, n.2, e1507.  Epub 01-Jun-2021. ISSN 0034-7523.


Aged adults generally have different pathologies, which implies high consumption of drugs, with which, this population group is one of those that can make the higher number of errors when using medication drugs.


To evaluate the behavior of drug use in an elderly population.


A descriptive cross-sectional study was carried out in a medical office in Arroyo Naranjo municipality, Havana, from October 2018 to May 2019. 365 geriatric patients made up the population they had diagnosis of chronic non-communicable disease (NCD). A random sampling was carried out for a total of 67 selected patients. The variables analyzed were age, sex, associated NCD, and medications used. The data were obtained by studying medical records and interviews. A percentage analysis was carried out to determine prevalence in each variable analyzed.


The drugs that stood out the most in the sample were antihypertensive and hypoglycemic drugs. The consumption of drugs was higher in patients aging 75 years and older and mainly in women. Men were the most irresponsible in adherence to treatment.


There was correspondence between the treatments and the pathologies in most cases with the exception of some patients in whom the benefit-risk ratio of the treatment was not fully met. However, generally, it is considered that there is no adequate use of the drugs in the sample.
