Moxiflox 400mg (Moxifloxacin)

Introduction

Moxifloxacin is a broad-spectrum antibiotic used to treat a wide range of bacterial infections. Moxiflox 400mg is a branded oral formulation that contains moxifloxacin and belongs to the fluoroquinolone class of antibiotics.

It works by killing bacteria and stopping their ability to multiply, making it effective in treating infections affecting the lungs, skin, abdomen, and more.

What is Moxiflox 400mg?

Moxiflox 400mg is a once-daily antibiotic used for moderate to severe bacterial infections. It is typically reserved for infections where other antibiotics may not be effective.

It is active against many Gram-positive and Gram-negative bacteria and is often used in hospital and outpatient settings.

How Moxifloxacin Works

Moxifloxacin works by inhibiting two essential bacterial enzymes:

• DNA gyrase
• Topoisomerase IV

These enzymes are required for bacterial DNA replication and repair. When blocked, bacteria cannot multiply, leading to their death and clearance from the body.
