Role of Nitrofurantoin in the Management of Urinary Tract Infection - A Systematic Review

Abstract

BACKGROUND Urinary tract infections are often caused by bacteria resistant to antibiotics which have evolved to be a major health issue in recent years. Often, urinary tract infections are very hard to treat and if not appropriately treated in time, may result in serious consequences, particularly, when it spreads to kidneys ultimately resulting in an increase in morbidity and mortality. Nitrofurantoin, a first line agent and has bactericidal action, frequently used to treat uncomplicated urinary tract infection. The literature was searched with published sources from Medline, PubMed and Embase search engines. Published articles were searched, of which 81 articles were eligible to be included for this systematic review. Nitrofurantoin is reduced by the action of bacterial flavoproteins to reactive intermediate compounds that non-specifically inactivate ribosomal proteins resulting in inhibition of protein synthesis. Various mechanisms seem to be responsible for the reduced capability of microorganism to acquire resistance in a faster manner. Nitrofurantoin exhibits high quality success against most bacteria anticipated in urinary tract infection. Nitrofurantoin has been recommended for prophylaxis in the treatment of reinfection in case of recurrent uncomplicated urinary tract infections in many western countries. Nitrofurantoin is one of the treatment options for urinary tract infection due to extended spectrum beta lactamase producing Escherichia coli. In pregnant women with urinary tract infection, nitrofurantoin can be appropriate treatment. Also, nitrofurantoin associated reactions have been reported in many studies. This review updates the clinical use of nitrofurantoin, including new facts about the role of nitrofurantoin in the therapy of community acquired urinary tract infection, adverse outcomes, complications, interactions and antibiotic resistance mechanism against different uropathogens.
