Nitrofurantoin is an antibacterial agent specific for urinary tract infections. Nitrofurantoin is highly soluble in urine, to which it may impart a brown color. Nitrofurantoin inactivates or alters bacterial ribosomal proteins and other macromolecules. Nitrofurantoin has been shown to be active against the following bacteria: Gram-Positive Aerobes Staphylococcus saprophyticus, Coagulase-negative staphylococci (including Staphylococcus epidermidis), Enterococcus faecalis, Staphylococcus aureus, Streptococcus agalactiae, Group D streptococci, Viridans group streptococci. Gram-Negative Aerobes- Escherichia coli, Citrobacter amalonaticus, Citrobacter diversus, Citrobacter freundii, Klebsiella oxytoca, Klebsiella ozaenae.
Antacids containing Magnesium Trisilicate, when administered concomitantly with Nitrofurantoin, reduce both the rate and extent of absorption of Uricosuric drugs, such as Probenecid and Sulfinpyrazone, can inhibit renal tubular secretion of Nitrofurantoin.
The most frequent clinical adverse events are nausea, headache, and flatulence. Other less occurred adverse events are diarrhea, dyspepsia, abdominal pain, constipation, emesis, dizziness and drowsiness.
Occasional incidents of acute overdosage of Nitrofurantoin have not resulted in any specific symptoms other than vomiting. Induction of emesis is recommended.
Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women. This drug should be used during pregnancy only if clearly needed. Nitrofurantoin has been detected in human breast milk in trace amounts. Because of the potential for serious adverse reactions from Nitrofurantoin in nursing infants under one month of age, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
If acute, sub-acute or chronic pulmonary reactions occur, Nitrofurantoin should be discontinued. Antacid preparations containing magnesium trisilicate should not be taken while taking Nitrofurantoin.
