Comparative Analysis of Drug Interactions with Antibacterial Agents in the Treatment of Community-Acquired Pneumonia

According to the World Health Organisation, pneumonia and other lower respiratory tract infections are one of the leading causes of death all over the world. Simultaneous treatment of pneumonia with antibacterial drugs and concomitant medicines may result in adverse drug reactions (ADRs). The aim of the study was to analyse ADRs resulting from drug-drug interactions in different empiric antibiotic treatment regimens used for mild community-acquired pneumonia (CAP), taking into account the concomitant symptomatic non-antibacterial treatment and chronic disease treatment. Materials and methods: the authors analysed spontaneous reports in the VigiBase global database (starting from the date the database was created and until 15 February 2021) on ADRs resulting from interactions of medicinal products included in the Russian clinical guidelines for CAP.Results: the authors compiled a list of antibacterial drugs (amoxicillin+clavulanic acid, amoxicillin, ampicillin, azithromycin, clarithromycin, levofloxacin, moxifloxacin, cefotaxime, ceftriaxone, linezolid), as well as lists of medicinal products for symptomatic and concomitant treatment, based on the approved guidelines for management of CAP and frequent comorbid chronic diseases. They searched VigiBase for ADRs that may have resulted from drug-drug interactions involving these medicinal products. Conclusions: the analysis of adverse reactions used for mild CAP treatment demonstrated that the largest number of ADRs were associated with drug-drug interactions involving azithromycin, while the smallest number of ADRs were associated with cefotaxime and ceftriaxone. Further study of drug-drug interactions will help to prevent potential ADRs, identify rational drug combinations, and improve the existing patient management strategies.
