Abstract


Objectives: The primary objective of the study was to examine the effectiveness of azithromycin in the treatment of acute tonsillitis, pharyngitis, tonsillopharyngitis in adults (reduction or withdrawal of clinical symptoms), and the secondary objective of the study was to examine the tolerability of the administered treatment and patient compliance during the study.

Methods: This multi-centric, non-interventional study included 297 subjects with acute tonsillitis, pharyngitis or tonsillopharyngitis. Patients were administered film-coated tablets - azithromycin 500 mg (Azomex®) and followed-up 4 to 5 days. The patients were observed at 2 time points; baseline and one additional assessment. At both time points, we examined physical findings, general condition of the patient to establish severity of the disease. We also measured the tolerability and patient compliance. In the test lists of subjects, the physician, assessed the effectiveness of azithromycin according to the Likert’s scale.

Results: A total of 297 patients were included in the study. The median of symptom improvement was 3 (2.0-4.0) days, with 60 (28.1%) patients who had improvement after 2 days of administration, 135 patients (45.8%) after 3 days of administration, while the 77 patients (26.1%) experienced symptoms improvement within the period of 4 to 6 days after the start of treatment. The treatment outcome was successful in 260 (89.0%) patients, while in 32 (11.0%) the treatment outcome was unsuccessful, which was a significant difference in the successfulness of treatment with azithromycin (X2=159.0; p<0.001). Tolerability of azithromycin was reported to be very good by 235 patients (80.8%), good by 32 (11.0%) and unsatisfactory reported by 8 (2.7%) patients.

Conclusion: The effectiveness and tolerability of the drug azithromycin (Azomex®) film-tablets in the treatment of acute tonsillitis, pharyngitis, tonsillopharyngitis, was found to be good with a small percentage of reported mild side effects.
