Chloroquine Phosphate

Chloroquine Phosphate is a 4-aminoquinoline antimalarial and antirheumatic drug that accumulates in the parasite's digestive vacuole and disrupts haem detoxification, used for malaria prophylaxis and treatment, and in low-dose for rheumatoid arthritis and lupus erythematosus. Simson Pharma's Chloroquine Phosphate reference standard and impurities support compendial testing across these long-established therapeutic uses.
