Retrospective analysis of the safety profile of oral moxifloxacin in elderly patients enrolled in clinical trials
Abstract
BACKGROUND AND OBJECTIVE: As aging is associated with physiological changes, including renal and hepatic insufficiency, and a higher risk of drug interactions, special attention needs to be directed towards the safety of medications in the elderly. The objective of this analysis was to evaluate the safety of oral moxifloxacin in elderly patients who were enrolled in clinical trials and to compare these results to those of other commonly used antibacterials.
METHODS: Safety data from 27 prospective, randomised, comparative phase II/III trials of oral moxifloxacin included in the Bayer clinical trial database were pooled and analysed by age group ( or = 75 years of age) and by treatment group (moxifloxacin vs comparator). The primary endpoints included rates of treatment-emergent adverse events (all adverse events regardless of causality), drug-related adverse events, drug-related serious adverse events, deaths and premature discontinuations because of a treatment-emergent adverse event. A treatment by age group interaction test was used to determine if the comparison between moxifloxacin and the comparator group in the incidence rates of any treatment-emergent or drug-related adverse events were affected by increasing age.
RESULTS: Of the 12 231 patients who had valid safety data, 6270 had been treated with oral moxifloxacin and 5961 with a comparator antibacterial. The most frequently used comparators were cefuroxime and clarithromycin. Most patients (n = 9671) were or = 75…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 9,671 participants or records.
