Diclofenac pain tablets are commonly used clinically as pain relievers and anti-inflammatory drugs. This drug can inhibit the synthesis of prostaglandins, thus acting as an anti-inflammatory, analgesic, and antipyretic agent, and can treat acute and chronic inflammatory conditions commonly seen in clinical practice. For example, gouty arthritis, acute synovitis, rheumatoid arthritis, rheumatoid joints or osteoarthritis during an attack can be treated with diclofenac tablets for anti-inflammatory and pain relief. It is especially effective for joint inflammation. The main reason is that after taking this drug, the concentration of the drug remains in the joint for a longer period of time, thus having a better treatment effect on joint inflammation and joint pain. It can also reduce acute injuries and post-surgical pain, and the effect is relatively satisfactory.
