Malaria and Autoimmune Treatment
Hydroxychloroquine sulfate is an FDA-approved medication available by prescription only and sold under the brand name Plaquenil, among others. The “sulfate” refers to the addition of sodium to the pill a person takes; you can also get the base pill without the sodium addition. It’s primarily used as a treatment for certain types of malaria, or in some cases a preventive measure against it. It’s also commonly used to treat arthritis. The prescription medication is known as a disease-modifying anti-rheumatic drug (DMARD). It does this by regulating the activity of a overactive immune systems. It has also been shown to improve rashes caused by lupus.
For arthritis, the drug is known to reduce pain and joint stiffness over the long-term. Its effects for both rheumatoid arthritis and lupus typically take weeks to notice.
Hydrocholoroquine is also in the second phase of development as a possible immune modulator for patients with HIV.
