Tylenol and hydroxychloroquine What can you take instead of plaquenil Plaquenil and eye exams Hydroxychloroquine Plaquenil® is a 4-amino-quinoline antimalarial medication that is widely used to treat systemic lupus erythematosus SLE, rheumatoid arthritis, and related inflammatory and dermatological conditions. It is a hydroxylated version of chloroquine, with a similar mechanism of action. However, following an identical dose of hydroxychloroquine and chloroquine, tissue levels of chloroquine are 2.5 times those of hydroxychloroquine. Hydroxychloroquine mechanism of action Hydroxychloroquine is both an antimalarial drug and a disease-modifying anti-rheumatic drug DMARD. As an antimalarial drug, hydroxychloroquine has been shown to accumulate in malaria parasite lysosomes, increasing the pH. Jan 05, 2020 Hydroxychloroquine binds to melanin, accumulates in the RPE, and remains there for long periods of time. It is directly toxic to the RPE, causing cellular damage and atrophy 2. This occurs due to disruption of RPE metabolism, specifically from lysosomal damage 5, and reduced phagocytic activity toward shed photoreceptor outer segments. Hydroxychloroquine is used to treat lupus erythematosus and rheumatoid arthritis. It isn’t fully understood how this drug works to treat lupus erythematosus or rheumatoid arthritis. That means you may need to take it with other drugs. It treats malaria by killing the parasites that cause the disease.

Hydroxychloroquine is a 4-aminoquinoline with immunosuppressive, antiautophagy, and antimalarial activities. Although the precise mechanism of action is unknown, hydroxychloroquine may suppress immune function by interfering with the processing and presentation of antigens and the production of cytokines. Hydroxychloroquine is an aminoquinoline like chloroquine. It is a commonly prescribed medication in the treatment of uncomplicated malaria, rheumatoid arthritis, chronic discoid lupus erythematosus, and systemic lupus erythematosus. Hydroxychloroquine is also used for the prophylaxis of malaria in regions where chloroquine resistance is unlikely. Mechanism Hydroxychloroquine is thought to improve symptoms of systemic diseases by preventing inflammation. For example, to treat both rheumatoid arthritis and systemic lupus erythematosus SLE, it has been hypothesized that the drug suppresses T-lymphocytes by increasing the pH inside lysosomes, which disables leukocyte chemotaxis.
