Osteotec Tab 50mg is a medicine that combines the powerful properties of diclofenac sodium and misoprostol. Diclofenac Sodium is a nonsteroidal anti-inflammatory drug (NSAID) known for its ability to reduce pain and inflammation. It works by inhibiting the production of prostaglandins, which are substances in the body responsible for causing pain and swelling. Misoprostol, is a synthetic prostaglandin E1 analog. It is primarily used to protect the stomach lining and prevent gastric ulcers. Misoprostol acts by increasing the production of protective mucus and reducing acid secretion in the stomach. The tablet is commonly prescribed for individuals suffering from osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and other inflammatory musculoskeletal disorders.
