This drug, can be used for a vast spectrum of maladies including ductus arteriosus, periarthritis, tennis elbow, acute brachial neuritis, gouty arthritis, ankylosing spondylitis, bursitis, tendinopathy, osteoarthritis, rheumatoid arthritis, tumescence, pain, elbow tendinopathy, inflammation, and musculoskeletal pain, is celebrated for its versatility. The roots of this pioneering drug, originally cultivated by the esteemed iROKO Partners Ltd., can be traced back to June 1965, when it first received its approval. With its COX inhibiting properties, indomethacin engenders a plethora of benefits by effectively mitigating inflammation and providing pain relief in a wide range of conditions.
