About Lenac 200mg Tablet SR

It is primarily used to relieve pain and inflammation in conditions like arthritis, ankylosing spondylitis, and other musculoskeletal disorders.

Patients should use it under medical supervision, especially if they have any pre-existing health conditions.

How It Works (Mechanism of Action)

Aceclofenac works by blocking the action of a substance in the body called cyclo-oxygenase (COX). This enzyme is involved in the production of prostaglandins, which are chemicals that promote inflammation, pain, and fever.

Scientifically, Aceclofenac is a non-selective COX inhibitor, which means it inhibits both COX-1 and COX-2 enzymes. This leads to a reduction in the synthesis of prostaglandins, thereby reducing inflammation and pain.

Key Benefits

  • Pain Relief — Helps reduce pain associated with various forms of arthritis.
  • Anti-inflammatory — Decreases swelling and inflammation in affected areas.
  • Improves Mobility — By reducing pain and swelling, it can help improve joint movement.

How Long Does It Take to Work?

Initial improvement in pain and inflammation can be noticed within a few hours after taking the medication. For full therapeutic effects, it may take a few days to a week. If there is no improvement in symptoms after a week, consult your doctor.
