Nalidixic Acid + Metronidazole

Introduction

Nalidixic Acid + Metronidazole is a combination of two potent antibiotics used to treat a wide range of bacterial and protozoal infections. Nalidixic Acid is effective against urinary tract infections caused by gram-negative bacteria, while Metronidazole targets anaerobic bacteria and parasites. Together, they provide a dual action approach to tackle infections in the digestive tract, urinary system, and reproductive organs. This combination is commonly prescribed when mixed infections are suspected or confirmed. It should be used under medical supervision and for the prescribed duration to ensure complete eradication of the infection.

Uses of Nalidixic Acid + Metronidazole

• Urinary tract infections (UTIs)
• Gastrointestinal infections
• Amoebiasis and dysentery
• Pelvic inflammatory disease
• Post-surgical infections in the abdomen
• Mixed bacterial and protozoal infections

How Nalidixic Acid + Metronidazole Works

Nalidixic Acid stops the growth of bacteria by interfering with their DNA replication process, mainly targeting gram-negative bacteria in the urinary tract. Metronidazole enters microbial cells and damages their DNA structure, effectively killing anaerobic bacteria and protozoa. When combined, they offer broad-spectrum coverage against a variety of pathogens.
