Indomethacin is a potent NSAID known for its effective pain-relieving, anti-inflammatory, and fever-reducing properties. It provides effective relief in conditions like arthritis, gout, bursitis, and tendonitis, and is a trusted option in short-term and specific clinical cases.
Amber Lifesciences Pvt. Ltd., a respected Indian pharmaceutical exporter, produces high-quality Indomethacin formulations and supplies them to global markets, including LATAM countries such as Brazil, Mexico, Argentina, Peru, and Colombia.

Primary Uses of Indomethacin

  • Rheumatoid & Osteoarthritis, Ankylosing Spondylitis
  • Acute Gouty Arthritis
  • Bursitis and Tendonitis
  • Patent Ductus Arteriosus (PDA) Closure in newborns
  • Off-label Uses: Pericarditis, postoperative heterotopic ossification, and menstrual cramps

Mechanism of Action: How Indomethacin Works

  • Non-Selective COX Inhibition
    Blocks COX-1 and COX-2 enzymes, reducing prostaglandin production (PGE₂, PGI₂), which lowers pain, swelling, and fever.
  • Inflammation Modulation
    Decreases neutrophil migration
    Stabilizes lysosomal membranes
    It may affect the NF-κB pathway to reduce inflammation
