Introduction

Martifur MR 100mg is a modified release (MR) formula that contains Nitrofurantoin, which is an antibiotic commonly employed for treating urinary tract infections (UTIs). It is effective against numerous typical bacteria that cause inflammation in the urinary tract, which makes it an ideal option for patients with uncomplicated UTIs and cystitis in particular.

What is Nitrofurantoin?

• Generic Name: Nitrofurantoin
• Brand Name: Martifur MR (and others)
• Drug Class: Nitrofurans, broad-spectrum antibiotic
• Dosage Form: Modified-release capsules/tablets, 100 mg

Nitrofurantoin functions mainly within the urinary tract, which is why it concentrates in urine and has antibacterial properties.

Mechanism of Action

Nitrofurantoin functions by stopping the bacterial enzymes that are involved in protein, DNA, and the synthesis of cell walls. The drug is converted inside the cell of the bacteria to reactive intermediates, which damage a variety of cells, leading to an end-of-life for bacteria’s life.

The multi-targeting mechanism decreases the possibility of bacterial resistance.
