Abstract

Urinary tract infections (UTI) are among the most frequent medical conditions requiring outpatient treatment. Single dose oral fosfomycin (300 mg) and the older nitrofurantoin (100 mg for 5 days) have been found to be more effective than other first-line drugs in multiple studies. This systematic review and meta-analysis were carried out with the objective of evaluating their comparative efficacy and safety in the management of uncomplicated UTI. Two authors independently searched PubMed, Cochrane Central, Embase, and Google Scholar till Nov 2020 using MeSH terms and free text. Randomized controlled trials (RCTs) comparing both drugs for efficacy and safety in uncomplicated UTI in adult women were included. The primary outcome measures were microbiological and clinical cure rates. The search resulted in n = 663 studies out of which only four studies (three for treatment of uncomplicated UTI in women and one for asymptomatic bacteriuria in pregnancy) satisfied the selection criteria. No significant differences in clinical, (RR 0.95, 95% CI - 0.81, 1.12) and microbiological cure, (RR 0.96, 95% CI - 0.84, 1.08) were found within 4 weeks of treatment. The incidence of adverse events was found to be more in fosfomycin relative to the nitrofurantoin group (RR 1.05, 95% CI - 0.59, 1.87). Hence, single-dose fosfomycin presents a potentially useful and safe treatment option for the treatment of uncomplicated UTI in women and asymptomatic bacteriuria in pregnancy.
