Diclofenac Sodium API (Active Pharmaceutical Ingredient) is a non-steroidal anti-inflammatory drug (NSAID) in powder form, commonly used in the pharmaceutical industry. It is chemically synthesized to provide potent analgesic, anti-inflammatory, and antipyretic effects, making it effective in treating various painful conditions such as arthritis, gout, and postoperative pain. Diclofenac Sodium works by inhibiting the production of prostaglandins, which are chemical messengers involved in inflammation and pain signaling. This mechanism helps alleviate symptoms and improve quality of life for patients suffering from inflammatory disorders. The powder form allows for flexible formulation into tablets, capsules, gels, or topical creams, ensuring diverse administration options based on patient needs and therapeutic requirements. As a widely recognized and trusted medication, Diclofenac Sodium continues to be a cornerstone in managing pain and inflammation globally.
