Medicine Description plaquenil 200 mg
plaquenil 200 mg tablets is a medication that primarily acts as an antimalarial agent but also possesses significant immunomodulatory properties. Hydroxychloroquine sulfate, the active ingredient, interferes with the communication between immune cells and inhibits the function of lysosomes within cells. This action helps to reduce the immune system's overactivity, which is particularly beneficial in autoimmune diseases. Additionally, it disrupts the pH of the intracellular compartments, impeding the replication of parasites within red blood cells, thus effectively reducing parasitic load in malaria. Its dual functionality makes it valuable in treating various inflammatory conditions as well.
