Microbiology - Malaria Mechanism of action 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. The understanding that one mechanism of action of hydroxychloroquine is the antagonism of TLR7 and TLR9 signaling is also intriguing, given the postulated roles of IFN-α in endothelial dysfunction and abnormal vascular repair. 177 Prospective studies demonstrating a cardioprotective effect of hydroxychloroquine in patients with SLE are needed.
