How is Chloroquine classified pharmacologically?

Chloroquine is classified pharmacologically as an antiparasitic and anti-inflammatory agent. Primarily, it is known for its effectiveness in treating infections caused by protozoa, particularly malaria, which categorizes it as an antiparasitic. The drug works by interfering with the growth and reproduction of the malaria parasite within red blood cells.

Furthermore, chloroquine's anti-inflammatory properties contribute to its use in certain autoimmune diseases, such as rheumatoid arthritis and lupus erythematosus. By modulating immune responses, chloroquine helps reduce inflammation and provides symptomatic relief for these conditions.

This dual classification into antiparasitic and anti-inflammatory categories highlights the drug's versatile mechanism of action, distinguishing it from agents that only target viral, bacterial, or fungal pathogens.
