Description

Introduction

Nitrofurantoin Sustained Release (SR) Tablets are a widely used antibiotic medication primarily prescribed for the treatment and prevention of urinary tract infections (UTIs). This formulation is designed to release the drug gradually over time, ensuring prolonged effectiveness while reducing the frequency of dosing. Nitrofurantoin is particularly effective against bacteria that commonly cause UTIs, such as Escherichia coli, Enterococcus, and Staphylococcus saprophyticus.

This article explores the composition, mechanism of action, therapeutic uses, dosage, precautions, and potential side effects of Nitrofurantoin Sustained Release Tablets.
 

Composition and Mechanism of Action

1. Nitrofurantoin:

• A synthetic nitrofuran antibiotic with bactericidal properties.

• Works by interfering with bacterial enzyme systems involved in carbohydrate metabolism, leading to bacterial cell death.

• Effective primarily against Gram-negative and some Gram-positive bacteria responsible for UTIs.

2. Sustained Release Formulation:

• Provides a controlled release of the drug over an extended period, reducing the need for frequent dosing.

• Ensures consistent drug levels in the bloodstream, improving patient compliance and minimizing side effects.

Therapeutic Uses

The Nitrofurantoin Sustained Release Tablets are primarily used for the following conditions:

1. Acute Uncomplicated Urinary Tract Infections (UTIs):

   • Effective against common uropathogens like E. coli and Klebsiella pneumoniae.

2. Recurrent UTIs:

   • Often prescribed for patients with frequent UTI episodes to prevent recurrence.

3. Asymptomatic Bacteriuria in Pregnancy:

   • Used in certain cases where bacterial infection is detected without symptoms, especially in pregnant women to prevent complications.

4. Prophylaxis for UTIs:

   • Given to patients prone to recurrent infections, particularly postmenopausal women and those with anatomical abnormalities of the urinary tract.

Dosage and Administration

The dosage of Pharma Franchise for Nitrofurantoin Sustained Release Tablets depends on the severity of the infection, patient’s age, weight, and overall health condition. It is generally prescribed as follows:

• Adults: 100 mg every 12 hours for 5–7 days for acute UTIs.

• Long-Term Prophylaxis: 50-100 mg once daily for several months as per doctor’s recommendation.

• Children: Not typically used in children under 12 years unless advised by a physician.

• Pregnant Women: Safe in the second and third trimesters but should be avoided at term (38–42 weeks) due to risk of hemolytic anemia in newborns.

• With Food: Nitrofurantoin should be taken with meals to enhance absorption and minimize stomach upset.

• Missed Dose: If a dose is missed, take it as soon as possible. If it is close to the next dose, skip the missed dose—do not double dose.

Precautions and Warnings

Before starting PCD Franchise for Nitrofurantoin Sustained-Release Tablets, consider the following precautions:

1. Kidney Function Impairment:

   • Not recommended for patients with severe renal impairment (Creatinine Clearance < 60 mL/min) as drug accumulation can occur.

2. Liver Disorders:

   • Patients with a history of hepatic dysfunction should use it cautiously.

3. Pregnancy and Breastfeeding:

   • Safe during most of pregnancy but should be avoided near delivery.

   • Not recommended during breastfeeding if the infant is younger than one month due to risk of hemolytic anemia.

4. Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency:

   • Can cause hemolysis (red blood cell breakdown) in individuals with this condition.

5. Lung Toxicity:

   • Long-term use has been associated with pulmonary fibrosis and hypersensitivity pneumonitis.

6. Peripheral Neuropathy:

   • Patients with preexisting nerve disorders should use with caution as Nitrofurantoin can cause nerve damage.

7. Drug Interactions:

   • Avoid concurrent use with magnesium-based antacids as they reduce drug absorption.

   • May interact with fluoroquinolone antibiotics and probenecid.

While Pharma Franchise for Nitrofurantoin Sustained Release Tablets are generally well tolerated, some patients may experience side effects, including:

Common Side Effects:

• Nausea, vomiting, and diarrhea

• Loss of appetite

• Headache and dizziness

• Mild skin rash

• Keep out of reach of children.

• Do not use expired tablets.

Benefits of Nitrofurantoin Sustained Release Tablets

1. Targeted Action in the Urinary Tract:

   • Nitrofurantoin is highly concentrated in urine, making it highly effective against UTIs.

2. Reduced Resistance:

   • Lower rates of bacterial resistance compared to other UTI antibiotics.

3. Sustained Release Formulation:

   • Ensures prolonged drug action, reducing the need for frequent dosing.

4. Minimal Impact on Gut Flora:

   • Unlike broad-spectrum antibiotics, it has minimal effect on beneficial intestinal bacteria.

5. Effective for UTI Prevention:

   • Useful for long-term prophylaxis in recurrent infection

Frequently Asked Questions (FAQs)

1. Can Nitrofurantoin SR Tablets be used for kidney infections?
No, Nitrofurantoin is primarily effective for lower UTIs (bladder infections) and is not recommended for kidney infections (pyelonephritis).

2. How long does it take for Nitrofurantoin to work?
Most patients experience symptom relief within 24 to 48 hours, but completing the full course is essential to prevent resistance.

3. Can I drink alcohol while taking Nitrofurantoin?
