🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Chloroquine works by concentrating in the acidic food vacuole of the malaria parasite, where it inhibits the polymerization of toxic heme into inert hemozoin. This leads to accumulation of toxic heme, which damages the parasite's membrane and causes its death. In autoimmune conditions, chloroquine modulates the immune system by interfering with antigen processing and presentation, and by inhibiting the production of inflammatory cytokines.
