The main painkillers for the treatment of rheumatism are colchicine and non-steroidal painkillers, such as ericiclib tablets and diclofenac sodium extended-release tablets, and the painkillers should be selected according to the patient’s condition. Colchicine can generally be taken orally for anti-inflammatory and pain relief during the acute phase of the patient’s pain, i.e. within 24 hours. Colchicine can inhibit the chemotaxis of leukocytes in the joints, which has a rapid anti-inflammatory and pain-relieving effect. If the pain of gout exceeds 24 hours, the effect of colchicine on pain relief will be less effective, then you can consider non-steroidal pain medications, such as ericiclib tablets or diclofenac sodium extended-release tablets, for anti-inflammatory and pain relief, but these drugs should be used with attention to stomach protection.
