Mechanism of action

Hydroxychloroquine accumulates in lysosomes and endosomes, raising their pH and interfering with antigen presentation and toll-like receptor activation. This suppresses the production of pro-inflammatory cytokines such as TNF-α, IL-6, and IL-17, making it effective in treating autoimmune and inflammatory conditions. It also has weak anticoagulant properties and may reduce thrombotic events.
