Unaccepted Hydroxychloroquine does not prevent relapses in patients with P. ovale malaria since it is not effective against exo-erythrocytic forms of the parasite. Hydroxychloroquine plaquenil and pregnancy Eye exam for plaquenil Chloroquine po 300 mg daily Plaquenil and inflammation levels The antimalarial agents chloroquine and hydroxychloroquine have been used widely for the treatment of rheumatoid arthritis and systemic lupus erythematosus. These compounds lead to improvement of clinical and laboratory parameters, but their slow onset of action distinguishes them from glucocorticoids and nonsteroidal antiinflammatory agents. Jan 01, 2020 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 efficacy of antimalarials, especially hydroxychloroquine HCQ, in preventing systemic lupus erythematosus SLE flares is well demonstrated. However, many studies show that the percentage of SLE patients treated with HCQ remains low. [ It may be used in addition to nonsteroidal anti-inflammatory agents.] Lupus erythematosus, discoid (treatment) or Lupus erythematosus, systemic (treatment)—Hydroxychloroquine is indicated as a suppressant for chronic discoid and systemic lupus erythematosus . falciparum , originally seen only in Southeast Asia and South America, are now documented in all malarious areas except Central America west of the Canal Zone, the Middle East, and the Caribbean.

Hydroxychloroquine HCQ is an antimalarial agent that has been used in systemic lupus erythematosus SLE and rheumatoid arthritis RA treatments for many years. Recently, advances in our understanding of its mechanisms of action have expanded the therapeutic prospects of HCQ 1–3. Hydroxychloroquine HCQ is recommended for thromboprophylaxis in patients with systemic lupus erythematosus and aPL. We aimed at identifying mechanisms responsible for the beneficial effects of HCQ in the APS.
