These drugs treat lupus symptoms by mildly suppressing the immune system, which reduces inflammation throughout the body. Hydroxychloroquin safety Ra drug plaquenil Plaquenil and gabapentin An antimalarial treats lupus by decreasing the production of autoantibodies, which leads to decreased inflammation in the heart, lungs, joints, and skin.

Hydroxychloroquine has largely replaced quinacrine and chloroquine due to its better safety profile 1. The pharmacokinetics of antimalarials. Chloroquine and hydroxychloroquine are chemically similar and are part of the amino-quinoline family. It may be related to an inability to clear damaged cells from the body, which causes excessive stimulation of the immune system.

Both chloroquine and quinacrine, and to a lesser extent hydroxychloroquine, inhibited arachidonate release and eicosanoid formation induced by phorbol diester. Chloroquine phosphate and hydroxychloroquine sulfate are substituted 4-amino quinoline compounds that differ only by a hydroxy group. Quinacrine hydrochloride also has the 4-amino quinoline radical but has, in addition, a benzene ring; it is classified as an acridine compound. The 4-amino quinoline.
