It may have both an anti-spirochaete activity and an anti-inflammatory activity, similar to the treatment of rheumatoid arthritis. And caution is required if patients have certain heart conditions, diabetes, psoriasis etc. Mechanism of action of hydroxychloroquine in rheumatoid arthritis Hydroxychloroquine sulfa allergy Plaquenil and eye floaters Does plaquenil cause skin peeling on hands Chloroquine Phosphate is the phosphate salt of chloroquine, a quinoline compound with antimalarial and anti-inflammatory properties. Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. Mg 250 mg of chloroquine phosphate daily. a When used in conjunction with topical corticosteroids in treatment of discoid lupus erythematosus, skin lesions may regress within 3–4 weeks and new lesions may not appear. a When systemic and cutaneous manifestations of lupus erythematosus subside. A 16.67 mg chloroquine PHOSPHATE/mL oral suspension equivalent to 10 mg chloroquine BASE/mL may be made from tablets. Crush two 500 mg chloroquine PHOSPHATE tablets equivalent to 300 mg BASE/tablet in a mortar and reduce to a fine powder. Add a small amount of sterile water for irrigation. The most serious adverse effects affect the eye, with dose-related retinopathy as a concern even after hydroxychloroquine use is discontinued.

This paper presents the current state of knowledge on chloroquine disposition, with special emphasis on stereoselectivity and microsomal metabolism. In addition, the impact of the patient’s physiopathological status and ethnic origin on chloroquine pharmacokinetics is discussed.
