Acide Nalidixique
Acide Nalidixique Uses, Dosage, Side Effects, Food Interaction and all others data.
Nalidixic acid is a synthetic narrow spectrum antibacterial. It is bacteriostatic or bactericidal depending on the concentration. Nalidixic acid appears to act by inhibiting bacterial DNA synthesis, possibly by interfering with DNA polymerization. It is rapidly and completely absorbed from the G.I. Tract. Parent drug and active metabolites are distributed to most tissues specially to the kidney and to the urine.
Nalidixic acid is a quinolone antibacterial agent for oral administration. Nalidixic acid has marked antibacterial activity against gram-negative bacteria including Enterobacter species, Escherichia coli, Morganella Morganii; Proteus Mirabilis, Proteus vulgaris, and Providencia rettgeri. Pseudomonas species are generally resistant to the drug. Nalidixic acid is bactericidal and is effective over the entire urinary pH range. Conventional chromosomal resistance to nalidixic acid taken in full dosage has been reported to emerge in approximately 2 to 14 percent of patients during treatment; however, bacterial resistance to nalidixic acid has not been shown to be transferable via R factor.

Uses
Nalidixic acid is used for -
- Urinary tract infections caused by susceptible Gram-negative microorganisms, including the majority of Proteus strains, Klebsiella, Enterobacter spp. and E. coli.
- Gastrointestinal infections caused by Salmonella and Shigella.
Acide Nalidixique is also used to associated treatment for these conditions: Urinary Tract Infection
How Acide Nalidixique works
Evidence exists for Nalidixic acid that its active metabolite, hydroxynalidixic acid, binds strongly, but reversibly, to DNA, interfering with synthesis of RNA and, consequently, with protein synthesis.
Dosage
Acide Nalidixique dosage
Adults:
- Initial: Oral 1 gm every 6 hours for 7 days reducing to 500 mg every 6 hours.
Infants and children 3 month of age and over:
- Initial: Oral 13.75 mg/kg body weight every six hours for one or two weeks.
- Maintenance: Oral 8.25 mg/kg body weight every six hours or as prescribed by the physician.
Should be taken with food.
Side Effects
Gastro-intestinal disturbances including nausea, vomiting, diarrhoea, haemolysis in G6PD deficiency, allergic reaction including urticaria, rashes, fever, arthralgia, eosinophilia, also myalgia, muscle weakness, phototoxicity, jaundice, visual disturbances and convulsions.
Toxicity
ORAL (LD50): Acute: 1160 mg/kg [Rat]. 572 mg/kg [Mouse]. Toxic psychosis, convulsions, increased intracranial pressure, or metabolic acidosis may occur in patients taking more than the recommended dosage. Vomiting, nausea, and lethargy may also occur following overdosage.
Precaution
General: Should be used with caution in liver disease, epilepsy or severe cerebral arteriosclerosis patients. Periodic blood counts and renal and liver function tests should be performed if treatment is continued for more than 2 weeks. If bacterial resistance emerges, rapid change of drug should be made.
Children: Should not be used to infants less than 3 months of age.
Interaction
Concomitant use of Nalidixic acid with melphalan there have been reports of death froms severe blood containing diarrhoea caused by hemorrhagic ulcerative colitis. Probenecids inhibits tubular secretion of nalidixic acid and may therefore elevate serum concentration, possibly enhancing toxicity. Chlorpromazine and Perphenazine have been shown to potentiate the effect of Acide Nalidixique in vitro.
Food Interaction
- Drink plenty of fluids.
- Take with food. Food reduces irritation.
Elimination Route
Following oral administration, nalidixic acid is rapidly absorbed from the gastrointestinal tract. Bioavailability is approximately 96%. Absorption may be delayed if taken with antacids.
Half Life
1.1 to 2.5 hours in healthy adult patients, and up to 21 hours in patients with impaired renal function.
Elimination Route
Following oral administration, NegGram is rapidly absorbed from the gastrointestinal tract, partially metabolized in the liver, and rapidly excreted through the kidneys. Approximately four percent of NegGram is excreted in the feces.
Pregnancy & Breastfeeding use
Pregnancy: There is the possibility that it may cause cartilage damage and as it is a DNA-gyrase inhibitor there is a possibility of causing DNA damage too. Nalidixic acid is excreted in breast milk and there is a report of hemolytic anaemia in a breast feed child of an azotemic mother.
Contraindication
Acide Nalidixique is contraindicated to known hypersensitivity to Nalidixic acid, history of convulsive disorders and patients with porphyria. Should be used with caution in patients with liver and renal disease. Also in glucose 6 - phosphate dehydrogenase deficiency.
Special Warning
Renal Impairment: Reduced doses should be considered.
Hepatic Impairment: Reduced doses should be considered.
Acute Overdose
Symptoms: Toxic psychosis, convulsions, increased intracranial pressure, metabolic acidosis, vomiting, nausea, lethargy.
Management: Increase fluid admin; supportive measures. Anticonvulsants may be used in severe cases.
Storage Condition
Store at room temperature, up to 25° C

FAQ
What is Acide Nalidixique used for?
Acide Nalidixique is a quinolone antibiotic used to treat urinary tract infections. Acide Nalidixique 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.
How safe is Acide Nalidixique?
It was found that Acide Nalidixique was an effective and safe antimicrobial agent in acute infectious diarrhoea. It cut down the days of hospitalisation and cost. It was well tolerated even in children less than 3 months.
How does Acide Nalidixique work?
Acide Nalidixique concentrates in the renal tubules and bladder and exerts its local antibacterial actions by interference of DNA gyrase activity, thereby inhibiting DNA synthesis during bacterial replication in a dose-dependent manner.
