What Is Diclofenac Sodium 75 mg?

Diclofenac sodium 75 mg is a nonsteroidal anti-inflammatory drug (NSAID) commonly prescribed to reduce pain, inflammation, and stiffness. It works by blocking the production of prostaglandins—chemicals in the body that trigger pain and swelling.

Key points about diclofenac sodium 75 mg:

• It relieves moderate to severe pain.
• It reduces inflammation in joints and soft tissues.
• It’s available in tablet form (extended-release or immediate-release) for once- or twice-daily dosing.

How Diclofenac Sodium 75 mg Works

Diclofenac sodium 75 mg inhibits the enzyme cyclo-oxygenase (COX), which has two main forms:

• COX-1: Helps protect the stomach lining and maintain kidney function.
• COX-2: Produces prostaglandins that cause pain and inflammation.

By targeting both COX-1 and COX-2, diclofenac sodium 75 mg:

• Reduces the body’s inflammatory response.
• Lowers fever.
• Alleviates pain signals reaching the brain.
