General Information on Plaquenil
Plaquenil is used to treat specific types of malarial infections (caused by P. malariae, Plasmodium vivax, susceptible strains of P. falciparum and P. ovale). It is also prescribed for the treatment of rheumatoid arthritis and lupus (including chronic discoid lupus and systemic lupus erythematosus).
Hydroxychloroquine, the main active ingredient in Plaquenil, is also its chemical name, and it belongs to a family of drugs known as antimalarial, anti-inflammatory (disease-modifying), and anti-rheumatic medications. It works by penetrating the bacteria in infected RBCs and forming complexes with parasite DNA. This action interferes with the important internal functions of bacteria, which leads to their death.
Plaquenil works differently in the case of rheumatoid arthritis and lupus. It restricts immune system reactions that are considered to be the causes of these diseases.
The medication is available in the form of a tablet. The drug is a prescription medication, which means you should consult your doctor before you buy Plaquenil.
