Furadantin (nitrofurantoin), a synthetic chemical, is a stable, yellow, crystalline compound. Furadantin is an antibacterial agent for specific urinary tract infections. Orally administered Furadantin is readily absorbed and rapidly excreted in urine. Blood concentrations at therapeutic dosage are usually low. Unlike many drugs, the presence of food or agents delaying gastric emptying can increase the bioavailability of Furadantin, presumably by allowing better dissolution in gastric juices. Nitrofurantoin is active against some gram positive organisms such as S. aureus, S. epidermidis, S. saprophyticus, Enterococcus faecalis, S. agalactiae, group D streptococci, viridians streptococci and Corynebacterium. Its spectrum of activity against gram negative organisms includes E. coli, Enterobacter, Neisseria, Salmonella and Shigella. It may be used as an alternative to trimethoprim/sulfamethoxazole for treating urinary tract infections though it may be less effective at eradicating vaginal bacteria. May also be used in females as prophylaxis against recurrent cystitis related to coitus. Nitrofurantoin is highly stable to the development of bacterial resistance, a property thought to be due to its multiplicity of mechanisms of action. Nitrofurantoin is activated by bacterial flavoproteins (nitrofuran reductase) to active reduced reactive intermediates that are thought to modulate and damage ribosomal proteins or other macromolecules, especially DNA, causing inhibition of DNA, RNA, protein, and cell wall synthesis. The overall effect is inhibition of bacterial growth or cell death.

Approved Use

Nitrofurantoin macrocrystals is specifically indicated for the treatment of urinary tract infections when due to susceptible strains of Escherichia coli, enterococci, Staphylococcus aureus, and certain susceptible strains of Klebsiella and Enterobacter species. Nitrofurantoin is not indicated for the treatment of pyelonephritis or perinephric abscesses. To reduce the development of drug-resistant bacteria and maintain the effectiveness of nitrofurantoin macrocrystals and other antibacterial drugs, nitrofurantoin macrocrystals 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 in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Nitrofurantoins lack the broader tissue distribution of other therapeutic agents approved for urinary tract infections. Consequently, many patients who are treated with nitrofurantoin macrocrystals are predisposed to persistence or reappearance of bacteriuria. Urine specimens for culture and susceptibility testing should be obtained before and after completion of therapy. If persistence or reappearance of bacteriuria occurs after treatment with nitrofurantoin macrocrystals, other therapeutic agents with broader tissue distribution should be selected. In considering the use of nitrofurantoin macrocrystals, lower eradication rates should be balanced against the increased potential for systemic toxicity and for the development of antimicrobial resistance when agents with broader tissue distribution are utilized.

PRIMARY Description: Lemon-yellow crystals or a yellow, crystalline powder; odourless or almost odourless. Solubility: Practically insoluble in water; very slightly soluble in ethanol (~750 g/l) TS; soluble in dimethylformamide R. Category: Antibacterial drug. Storage: Nitrofurantoin should be kept in a well-closed container, protected from light, and stored at a temperature not exceeding25?C. Labelling: The designation on the container of Nitrofurantoin should state whether the substance is the monohydrate or is in theanhydrous form. Additional information: Nitrofurantoin melts at about 271?C with decomposition. Nitrofurantoin and its solutions are discoloured byalkali and by exposure to light and are decomposed upon contact with metals other than stainless steel and aluminium. Definition: Nitrofurantoin contains not less than 98.0% and not more than 102.0% of C8H6N4O5, calculated with reference to thedried substance.
