Sulphacetamide

Introduction

Sulphacetamide is a sulfonamide-based antibacterial compound commonly used in the treatment of bacterial eye infections. It is available in the form of eye drops or ointments and works by inhibiting the growth of bacteria that cause infection. This composition is frequently prescribed for conditions like conjunctivitis and other superficial eye infections. Sulphacetamide is effective, fast-acting, and well-tolerated when used as directed. It belongs to the sulfa drug family and is typically recommended for short-term use to relieve symptoms such as redness, swelling, and discharge caused by bacterial invasion.

Uses of Sulphacetamide

• Treatment of bacterial conjunctivitis
• Management of blepharitis (inflammation of the eyelid)
• Used in superficial eye infections caused by susceptible bacteria
• Prevention of infection in minor eye injuries

How Sulphacetamide Works

Sulphacetamide works by inhibiting the synthesis of folic acid in bacteria, which is essential for their growth and replication. It blocks the enzyme dihydropteroate synthase, halting bacterial cell multiplication. As a result, it controls and eliminates the infection.

Do not touch the tip of the dropper or tube to avoid contamination.
