Mechanism of ActionMalaria - The precise mechanism by which hydroxychloroquine exhibits activity against Plasmodium is not known. Hydroxychloroquine, like chloroquine, is a weak base and
may exert its effect by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. It can also inhibit certain enzymes by its interaction with DNA.
Rheumatoid Arthritis and Systemic Lupus Erythematosus - The mechanisms underlying the anti-inflammatory and immunomodulatory effects of PLAQUENIL are unknown.
IndicationPLAQUENIL is indicated for the treatment of uncomplicated malaria due to P. falciparum, P. malariae, P. ovale, and P. vivax.
