Introduction: Antibiotic resistance is a growing problem. Adherence to national guidelines is one of the key factors necessary for the rational use of antibiotics. Aim: The aim of the study was to examine characteristics of antibiotic prescribing practice in primary health care in Novi Sad. Method: The analysis was designed as a descriptive, cross-sectional study based on the data obtained from the health institution Cvejić Pharmacy. The guidelines available to physicians at the time of prescribing were used to assess the compliance of the prescribed antibiotics with the guidelines. Additionally, the most frequently dispensed antibiotics for all diagnoses were recorded and results were expressed as a percentage of frequency of analyzed antibiotic prescriptions. Results: The study has shown that antibiotic prescriptions make 5.48% of all prescriptions (719 out of 13115), 513 (71.35%) of which were established by national guidelines, and 206 (28.65%) for less frequent diagnoses which was not included in national guidelines. In the study sample, 297 (65.42%) terapeutical regimes had adequate terapeutical dosage. The most commonly prescribed antibiotic groups were: macrolides (35.18%), penicillins (28.68%) and cephalosporins (14.60%). Conclusions: Irrational prescribing and dispensing of antibiotics is both national and global problem. It is necessary to pay close attention to antibiotics prescribing and dispensing. The focus should be on national guidelines and their extension.
