Nostiriazyn (Nitrofurantoin)

Nitrofurantoin, the active ingredient in Nostiriazyn, is a nitrofuran antibiotic presented as tablets for oral use. It is indicated for the treatment of uncomplicated urinary tract infections, primarily affecting the bladder, in adult patients. The drug works by interfering with bacterial enzyme systems and damaging bacterial DNA, leading to bacterial death.

GNH USA supplies Nostiriazyn as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company ensures product quality through strict regulatory compliance and provides reliable global logistics for qualified healthcare institutions.

Nitrofurantoin, the nitrofuran antibiotic in Nostiriazyn, is used to treat infections of the urinary tract caused by susceptible bacteria.

- Uncomplicated urinary tract infection: eliminates the causative bacteria, relieving symptoms such as dysuria, frequency, and urgency. - Acute cystitis: provides rapid bactericidal activity against common uropathogens, leading to clinical cure. - Recurrent urinary tract infection prophylaxis: reduces the frequency of infection episodes when administered over a prolonged period.

Nitrofurantoin may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Nausea: mild stomach upset often occurring early in therapy. - Loss of appetite: reduced desire to eat during treatment. - Headache: transient pain in the head. - Diarrhea: loose stools that may be self‑limiting. - Dizziness: light‑headed sensation, especially when standing quickly. - Urinary discoloration: brownish urine due to drug metabolites.

Serious or Rare Side Effects: - Pulmonary toxicity: interstitial lung disease presenting with cough and dyspnea. - Hepatotoxicity: liver enzyme elevations or hepatitis. - Hemolytic anemia: especially in patients with G6PD deficiency. - Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Acute renal failure: sudden loss of kidney function. - Peripheral neuropathy: tingling or numbness in extremities.

Before prescribing Nitrofurantoin, clinicians should consider several safety and handling precautions.

- Renal function: assess kidney function; avoid use if creatinine clearance is <60 mL/min. - Pregnancy: use only if clearly needed; safety data are limited. - G6PD deficiency: screen patients as hemolysis risk may increase. - Drug hypersensitivity: discontinue if rash, fever, or eosinophilia develop. - Concomitant medications: monitor for interactions that may affect drug levels. - Store at room temperature: keep tablets in the original container, protect from moisture and light.

Nitrofurantoin can interact with other medicines, altering its effectiveness or increasing toxicity.

Major Interactions (Avoid): - Antacids containing magnesium or aluminum: reduce absorption; separate dosing by at least 2 hours. - Probenecid: decreases renal excretion, raising plasma concentrations. - Fluoroquinolones: additive risk of tendon rupture when combined.

Moderate Interactions (Monitor Closely): - Warfarin: may enhance anticoagulant effect; monitor INR. - Diuretics: may increase risk of crystalluria; ensure adequate hydration. - NSAIDs: may affect renal function, altering drug clearance.
