Hydroxychloroquine Sulfate(Cat No.:A000121)is a widely used antimalarial and immunomodulatory drug. It works by interfering with parasite lysosomal activity and pH, effectively treating Plasmodium infections. Beyond malaria, it is commonly prescribed for autoimmune conditions such as rheumatoid arthritis and systemic lupus erythematosus, where it modulates immune responses by inhibiting antigen processing and cytokine production. Hydroxychloroquine Sulfate has also been investigated for antiviral activity in certain infections. Known for its oral bioavailability and long-term safety, it remains a cornerstone treatment for various inflammatory and parasitic diseases.
