Hydroxychloroquine is a 4-aminoquinoline antimalarial with actions similar to those of chloroquine but is mainly used in the treatment of SLE and rheumatoid arthritis. It interferes with digestive vacuole function within susceptible malarial parasites by increasing pH and interrupting with lysosomal degradation of Hb thus impeding normal cell function of sensitive parasites.
