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. Dry skin and plaquenil Plaquenil sister drug Plaquenil boils Mechanism of action of hydroxychloroquine as an antirheumatic drug. Fox RI1. Author information 1Department of Rheumatology, Scripps Clinic and Research Foundation, La Jolla, CA 92037. The antimalarial agents chloroquine and hydroxychloroquine have been used widely for the treatment of rheumatoid arthritis. Small amounts of hydroxychloroquine can be found in breastmilk, but international experts indicate this medication is acceptable while breastfeeding. MECHANISM OF ACTION. Plaquenil increases the pH of lysosomes and impairs complement-dependent antigen-antibody reactions. It also inhibits the chemotaxis of eosinophils and locomotion of neutrophils. The investigators treated these APS mice with hydroxychloroquine, finding that the treatment improved endothelium-dependent dilation at three weeks. The research, published Nov. 6 in PloS One, also indicated that hydroxychloroquine can improve nitric oxide synthase coupling and reduce oxidative stress. The most serious adverse effects affect the eye, with dose-related retinopathy as a concern even after hydroxychloroquine use is discontinued. The most common adverse effects are a mild nausea and occasional stomach cramps with mild diarrhea.

Hydroxychloroquine - Wikipedia. Is Hydroxychloroquine Helpful for Patients with Antiphospholipid.. Hydroxychloroquine decreases Th17-related cytokines in.. Hydroxychloroquine Plaquenil is a drug that is classified as an anti-malarial drug. Plaquenil is prescribed for the treatment or prevention of malaria.

Quinine was first recognized as a potent antimalarial agent hundreds of years ago. Since then, the beneficial effects of quinine and its more advanced synthetic forms, chloroquine and hydroxychloroquine, have been increasingly recognized in a myriad of other diseases in addition to malaria. 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.
