What It Is and How It Works
Ivermectin
Ivermectin works by binding to certain proteins in the cells of parasites, leading to their paralysis and death. This is effective against a range of parasitic worms and some external parasites.
Hydroxychloroquine
Hydroxychloroquine is an antimalarial drug that works by interfering with the lifecycle of the malaria parasite. It also has immunomodulatory effects, which makes it useful in treating autoimmune diseases like lupus and rheumatoid arthritis by moderating the body\’s immune response.
Indications / Uses
Ivermectin
Primarily, ivermectin is used to treat parasitic infections such as onchocerciasis (river blindness), strongyloidiasis, and certain other larval infections. It is approved in many countries for veterinary and human use.
Hydroxychloroquine
Hydroxychloroquine is primarily used as a prophylaxis and treatment for malaria. It is also widely used to manage autoimmune disorders such as lupus erythematosus and rheumatoid arthritis due to its anti-inflammatory properties.
Dosage Forms and Typical Dosing Considerations
Ivermectin
Ivermectin is usually available in oral tablet form and is sometimes administered as a topical preparation. The dosing is typically based on the condition being treated and the patient\’s weight.
Hydroxychloroquine
Hydroxychloroquine is commonly available in tablet form. Dosing varies significantly based on the indication, being generally higher for malaria treatment and prophylaxis compared to autoimmune diseases.
