Objective: The aim of this study is to determine the non- pediatric dosage form (NPDF) of medications used in the general pedi- atric service. Material and Methods: This retrospective, descriptive study was carried out by examining the archive documents of patients under the age of 12 who had received medication therapy in the last 6 months in the general pediatric service of a university hospital.Results: The median age [interquartile range (IQR)] of the 238 patients included in the study was 2 years (1-6), and 130 (54.6%) of them were female. The most common diagnoses in patients are diabetes mellitus (10%), upper respiratory tract infections (8.4%) and pneumonia (6.9%), NPDF medications use was detected in 96 (40.3%) of the patients. Out of a total of 729 medications used by the patients, 106 (14.5%) were classi- fied as NPDF medications. The most commonly used active ingredients among NPDF medications are allopurinol (6.3%), captopril (5%), phe- nobarbital (5%), furosemide (4.2%) and azathioprine (4.2%). NPDF medications were most frequently included in the cardiovascular sys- tem (26%), the digestive system (23%) and the nervous system (16%). Of the NPDF drugs, 57% were used in the 0-2 age group, 24% in the 3- 6 age group, and 19% in the 7-12 age group. There was no statistically significant difference in the distribution of NPDF drugs among patients in these age groups (p>0.05). Conclusion: It has been observed that NPDF medications are widely used in patients hospitalized in the gen- eral pediatric service. Especially the medications in the cardiovascular system group are drugs that are often used by manipulating their dosage forms. Evidence-based guidelines for the manipulation of medications are needed to improve the safety of pediatric medication therapy.
