Abstract:

Geriatric population ratio is increasing with the increase in life expectancy. Elderly inpatient ratio is higher than their ratio in the population. Elderly patients are within the sensitive population for clinical pharmacology as they have altered drug response, polypharmacy, drug adherence problems, solid oral pharmaceutic swallowing difficulties. It should be alerted due to their increased drug-related risks. There are many studies evaluating drug use in elderly inpatients. An elderly inpatient admitted to Maltepe University Faculty of Medicine is evaluated with clinical pharmacology perspective according to previous study perspectives. Seventy-nine years old retired teacher is internalized with the pneumonia diagnosis. She has an appendectomy and adenocarcinoma of the lung operations also hypertension, asthma in her history. She has parenteral nutrition support. The drugs she is administered during her hospital stay and after discharge evaluated for drug-drug interactions, drug-disease interactions, drug intake order, fasting condition obligations, It has been counted twenty different drugs during her hospital stay. They were administered orally, parenterally, topical or with nebulization. Important drug-drug interaction is reported with escitalopram and fluconazole that can increase escitalopram toxicity. Data has supported drugs that can affect electrolyte balance. Patient has been informed about drug use after discharge. Polypharmacy term depends but ten or more drugs are called polypharmacy in many sources. Polypharmacy does not always mean inappropriate drug use, it can depend on the patient and the diseases. Polypharmacy should be considered as a risk and should be tried to de-prescribe or to lower the dose.
