Chloroquine (CQ) then becomes protonated (to CQ 2+), as the digestive vacuole is known to be acidic (pH 4.7); chloroquine then cannot leave by diffusion. Chloroquine caps hemozoin molecules to prevent further biocrystallization of heme, thus leading to heme buildup. Chloroquine binds to heme (or FP) to form the FP-chloroquine complex; this ...
Hydroxychloroquine and chloroquine have numerous, potentially serious, side effects, such as retinopathy, hypoglycemia, or life-threatening arrhythmia and cardiomyopathy. [26] Both drugs have extensive interactions with prescription drugs, affecting the therapeutic dose and disease mitigation. [26] [27] Some people have allergic reactions to ...
They also have essentially 100% bioavailability and can be used for drugs that are poorly absorbed or ineffective when they are given orally. [25] Some medications, such as certain antipsychotics, can be administered as long-acting intramuscular injections. [37] Ongoing IV infusions can be used to deliver continuous medication or fluids.

Chloroquine and hydroxychloroquine are anti-malarial medications also used against some auto-immune diseases. [51] Chloroquine, along with hydroxychloroquine, was an early experimental treatment for COVID-19. [52] Neither drug has been useful to prevent or treat SARS-CoV-2 infection.
This MDA comprised 300 mg chloroquine base and 45 mg pyrimethamine weekly for nine weeks. An additional 300 mg chloroquine and 75 mg pyrimethamine plus 1500 mg sulfadoxine was added to this regimen in the first, fifth, and ninth week. Children received an adjusted equivalent of the adult dose. Follow-up consisted of yearly parasite surveillance.
One of the most notable scientific papers that first popularized hydroxychloroquine as a COVID-19 treatment was retracted from its journal due to ethical and methodological issues. Retractions in ...
Chloroquine is a water-soluble anti-malarial medication administered in the form of a tablet and is absorbed by the gastrointestinal tract. [12] Hydroxychloroquine, another anti-malarial, is used to treat quartan fever. Hydroxychloroquine is also typically administered to patients with lupus flares.
