Evaluation of efficacy and tolerability of nitrofurantoin versus ciprofloxacin in patients of urinary tract infection: a comparative study

Abstract

Background: UTIs are one of the most common infectious diseases encountered in out-patient departments on day to day basis. Nitrofurantoin and Ciprofloxacin are most commonly used antibiotics in the treatment of UTI. The present study was done to compare the efficacy and tolerability of nitrofurantoin and ciprofloxacin in patients of urinary tract infection.Methods: This prospective, open, randomized, parallel group, comparative study was conducted on 60 patients presenting with acute/uncomplicated or recurrent urinary tract infection in the outpatient Department of Urology, Rajindra Hospital attached to Govt. Medical College, Patiala, Punjab. They were divided into two groups, Group I and Group II of 30 cases each. Group I patients were put on Nitrofurantoin and Group II patients were put on Ciprofloxacin. Initially 100 patients were enrolled but only those who showed growth of uropathogens on baseline urine culture or those who completed the treatment were included in the study. The primary outcome measure was microbiological eradication on post treatment urine culture.Results: The age range of the patients in Group I and Group II was 19 to 68 years (43.40±14.58 years) and 20-60 years (39.77±13.49 years) respectively. The total no. of males and females who participated in this study were 32 (53.33%) and 28 (46.66%) respectively. The most common uropathogen associated with uncomplicated UTI was E. coli (80%), other organisms detected were Klebsiella species (16.67%), Staphylococcus aureus (3.33%) and Providencia (3.33%). Post treatment urine culture results showed significant difference between two groups, 5 patients (16.67 %) in case of Group I and 14 patients (46.67%) in case of Group II showed growth of micro-organisms post treatment. P-value comes out to be 0.017 which is significant.Conclusions: In this era of super bugs, nitrofurantoin is more efficacious than ciprofloxacin in the treatment of UTI. E. coli was found to be major organism causing UTI. Ciprofloxacin is less effective due to increasing antibiotic resistance among uropathogens. Both the drugs were well tolerated, no major significant adverse effects were encountered.
