DESCRIPTION

NALIGRAM (Nalidixic Acid) is a bactericidal antimicrobial agent used mainly in the treatment and prophylaxis of urinary tract infections caused by Gram-negative pathogen specially E. coli. It is effective against most Gram-negative bacilli with the notable exception of

Pseudomonas species. NALIGRAM (Nalidixic Acid) exerts its antibacterial activity by inhibiting DNA replication in the bacterial cell by inhibition of the enzyme DNA gyrase. It is considered as the first line treatment in cases of multiresistant Shigella infections. NALIGRAM

(Nalidixic Acid) shows high clinical and bacteriological cure rates in patients with bloody diarrhea caused by multiresistant Shigella and proved to be a childhood safe antimicrobial in the therapeutic dosage range.

COMPOSITION

Tablet : Each tablet contains Nalidixic Acid BP 500 mg.

PRECAUTIONS

Nalidixic Acid should not be administered with nitrofurantoin and anticoagulant. In case of renal failure the plasma half life may be as long as 21 hours instead of normal 8 hours. Overdosing of Nalidixic

Acid in children may develop intracranial pressure, therefore caution should be taken in case of paediatric treatment. Nalidixic Acid should be used after 48-72 hours from the onset of infection in cases of chronic shigellosis to avoid development of bacterial resistance.

Anticoagulant effect of nicoumalone and warfarin and toxicity of melphalan is enhanced by Nalidixic Acid. Probenecid reduces excretion of Nalidixic Acid.
