Neggram (Nalidixic Acid) - Summary



NegGram® Caplets
(nalidixic acid, USP)

NegGram®, brand of nalidixic acid, is a quinolone antibacterial agent for oral administration. Nalidixic acid is 1-ethyl-1,4-dihydro-7-methyl-4-oxo-1,8-naphthyridine-3-carboxylic acid. It is a pale yellow, crystalline substance and a very weak organic acid.

NegGram (nalidixic acid, USP) is indicated for the treatment of urinary tract infections caused by susceptible gram-negative microorganisms, including the majority of E. Coli, Enterobacter species, Klebsiella species, and Proteus species. Disc susceptibility testing with the 30 mcg disc should be performed prior to administration of the drug, and during treatment if clinical response warrants.

To reduce the development of drug-resistant bacteria and maintain effectiveness of NegGram and other antibacterial drugs, NegGram should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered when selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Published Studies Related to Neggram (Nalidixic Acid)

Randomized controlled comparison of ofloxacin, azithromycin, and an ofloxacin-azithromycin combination for treatment of multidrug-resistant and nalidixic acid-resistant typhoid fever. [2007.03]
Isolates of Salmonella enterica serovar Typhi that are multidrug resistant (MDR, resistant to chloramphenicol, ampicillin, and trimethoprim-sulfamethoxazole) and have reduced susceptibility to fluoroquinolones (nalidixic acid resistant, Na(r)) are common in Asia... enterica serovar Typhi with reduced susceptibility to fluoroquinolones (Na(r)) can be successfully treated with a 7-day course of azithromycin.

A comparative study of genotoxic effects in the treatment of trichomonas vaginalis infection: metronidazole or nalidixic acid. [2000.07]
We performed a prospective randomized study to compare the potential genotoxic effects of metronidazole and nalidixic acid which they are used in the treatment of Trichomonas vaginalis infection. 20 patients with Trichomonas vaginalis infections participated in this study.We conclude that in spite of wide use of nalidixic acid for Trichomonas vaginalis infection, because of its potential genotoxic effect its usage must be individualized especially for pregnant women and small babies.

A randomized controlled comparison of azithromycin and ofloxacin for treatment of multidrug-resistant or nalidixic acid-resistant enteric fever. [2000.07]
To examine the efficacy and safety of short courses of azithromycin and ofloxacin for treating multidrug-resistant (MDR, i.e., resistant to chloramphenicol, ampicillin, and cotrimoxazole) and nalidixic acid-resistant enteric fever, azithromycin (1 g once daily for 5 days at 20 mg/kg/day) and ofloxacin (200 mg orally twice a day for 5 days at 8 mg/kg/day) were compared in an open randomized study in adults admitted to a hospital with uncomplicated enteric fever.

Treatment of bacillary dysentery in Vietnamese children: two doses of ofloxacin versus 5-days nalidixic acid. [2000.05]
Nalidixic acid (NA: 55 mg/kg daily for 5 days) is the recommended treatment for uncomplicated bacillary dysentery in areas where multidrug-resistant Shigella are prevalent. An open randomized comparison of this NA regimen with 2 doses of ofloxacin (total 15 mg/kg) was conducted in 1995/96 in 135 Vietnamese children with fever and bloody diarrhoea...

Effect of antimicrobial (nalidixic acid) therapy in shigellosis and predictive values of outcome variables in patients susceptible or resistant to it. [1995.04]
We observed the clinical features and results of simple laboratory tests on stools of 33 children with bacteriologically proven shigellosis to identify features that could be used to assess the effectiveness of antimicrobial therapy. Persistence of fever (rectal temperature > 37.8 degrees C), abdominal pain/tenderness and anorexia on days 3 and 5 were significantly more common (P < 0.001) among children who received an antimicrobial to which the infecting Shigella was resistant...

Clinical Trials Related to Neggram (Nalidixic Acid)

Patients Response to Early Switch To Oral:Osteomyelitis Study [Not yet recruiting]
Based on the current literature, investigators hypothesize that patients with osteomyelitis who are treated with the standard approach of intravenous antibiotics for the full duration of therapy will have the same clinical outcomes as patients treated with the experimental approach of intravenous antibiotics with early switch to oral antibiotics. The primary objective of this study is to compare patients with osteomyelitis treated with the standard approach of intravenous antibiotics for the full duration of therapy versus patients treated with intravenous antibiotics with an early switch to oral antibiotics in relation to clinical outcomes at 12 months after discontinuation of antibiotic therapy. Secondary objectives of the study include the evaluation of adverse events related to the use of antibiotics as well as the cost of care evaluated from the hospital perspective.
