More effective for long term treatment of rheumatoid arthritis as devoid of long term adverse drug reactions, especially eye changes. Use of chloroquine is declining recently due to the fact that most strains have become resistant. It rapidly enters and gets concentrated in food vacuole, present within erythrocytes. If we want to avoid relapse, Primaquine is used to eradicate tissue schizontal activity. Previously used for chemoprophylaxis, now due to development of resistance, chloroquine is not used. Anti-amoebic effect –infection caused by Entamoeba histolytica) Amebic liver abscess (as chloroquine is concentrated in the liver) because: Used for long time for rheumatoid arthritis, but because of associated ocular adverse effects, precaution is taken to have eye examination every 4 to 6 month to check retinal changes.

Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme.
