Nitrofurantoin-Chinoin (Nitrofurantoin)

Nitrofurantoin acts by inhibiting bacterial enzymes involved in carbohydrate metabolism, particularly nitrofuran reductases. This inhibition leads to the generation of reactive intermediates that damage bacterial DNA, proteins, and cell wall structures, resulting in bacterial cell death while having limited effect on human cells.

The exact dose and duration of Nitrofurantoin-Chinoin are determined by the prescribing healthcare professional. The prescriber considers factors such as the severity of infection, the patient’s renal function, age, and any concomitant medications before setting an individualized dosing regimen.

Nitrofurantoin is classified as pregnancy category B, indicating no evidence of fetal risk in animal studies, but it is generally avoided in late pregnancy (≥38 weeks) because of potential neonatal hemolysis. The drug is excreted in breast milk; therefore, breastfeeding mothers should discuss risks and benefits with their healthcare provider.

To place an order, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India supplies hospitals, pharmacies, and procurement teams worldwide. After submission, the sales team will verify trade or institutional credentials, then respond with pricing, availability, shipping details (including any cold‑chain requirements), and required import documentation.

Nitrofurantoin is often preferred for uncomplicated urinary tract infections caused by Escherichia coli and other common pathogens because of its high urinary concentration and low systemic exposure. Compared with trimethoprim‑sulfamethoxazole, it retains activity against some resistant strains, but it is contraindicated in patients with poor renal function, whereas trimethoprim‑sulfamethoxazole may be used with dose adjustment.

Store Nitrofurantoin-Chinoin at ambient temperature, preferably below 25 °C. Keep the tablets in the original container, protect them from moisture and direct sunlight, and ensure the packaging remains tightly closed to maintain product stability throughout its shelf life.

Nitrofurantoin-Chinoin is taken orally, usually as a whole tablet swallowed with a full glass of water. It can be taken with food or milk to lessen gastrointestinal discomfort. Patients should follow the prescriber’s instructions regarding timing and whether doses should be spaced evenly throughout the day.

Serious adverse reactions include pulmonary toxicity (interstitial lung disease or acute respiratory distress), severe allergic responses such as anaphylaxis or Stevens‑Johnson syndrome, hemolytic anemia in individuals with G6PD deficiency, hepatic injury, and peripheral neuropathy. Patients should seek immediate medical attention if they experience breathing difficulty, rash, jaundice, or unexplained numbness.

Nitrofurantoin-Chinoin should be avoided in patients with severe renal impairment (eGFR <30 mL/min), known hypersensitivity to nitrofurantoin or other nitrofurans, G6PD deficiency, late pregnancy (≥38 weeks), and those with a history of nitrofurantoin‑induced pulmonary reactions. Clinicians must assess each patient’s medical history before prescribing.
