Abstract: Hydroxychloroquine sulfate (HCQ) is widely used in autoimmune connective tissue diseases and is a commonly prescribed drug for rheumatoid arthritis. Hydroxychloroquine sulfate has antimalarial, immunomodulatory, and antiviral effects. It exerts immunosuppressive effects through various mechanisms, such as inhibiting lysosomes and controlling the release of inflammatory factors. Hydroxychloroquine sulfate is extensively applied in clinical practice, not only for controlling the disease but also for significantly reducing the dosage of glucocorticoids, thereby lowering the recurrence rate of patients, its clinical efficacy is relatively good.
