Chloroquine phosphate vs hydroxychloroquine sulfate

Chloroquine phosphate and hydroxychloroquine sulfate should not be confused. They are not the same drugs. Yet, both of them are derived from the same chemical molecule, known as quinoline. Also, both drugs are used as antimalarial medications, but hydroxychloroquine sulfate is used more often as an antirheumatic drug. 

Their toxicity and therapeutic dosage are different. Nevertheless, they both share the same side effects and clinical indications. A common profound side effect due to them is retinopathy.

What is hydroxychloroquine sulfate used for?

Hydroxychloroquine sulfate is used to treat various conditions. These conditions include systemic lupus erythematosus, rheumatoid arthritis, porphyria cutanea tarda, Sjogren syndrome, and Malaria. Also, recently, some research studies claim that it is effective in SARS-CoV2 infection (the coronavirus). And if you want to purchase 

Hydroxychloroquine sulfate for lupus

Lupus is an autoimmune disease in which the immune system in a human becomes overactive and attacks the body. Symptoms of the disease vary depending on which tissue is being attacked. They can appear in different organs like joints, skin, kidneys, heart, and lungs.

In addition to being antimalarial, hydroxychloroquine sulfate possesses immunosuppressive effects. This is because it increases pH within intracellular vacuoles and alters processes such as assembly of macromolecules in the endosomes and posttranslational modifications of proteins in the Golgi apparatus. 

Research studies found that these properties interfere with antigen processing in antigen-presenting cells like macrophages. Also, an alkaline cytoplasmic environment interferes with the regular assembly of alpha and beta chains of MHC class II. These effects together lead to diminished antigen presentation and CD4+ T cell activation.

Hydroxychloroquine sulfate for Malaria

The mechanism of action of hydroxychloroquine (and other quinolone drugs) as an antimalarial drug isn’t completely understood. However, here is the most likely true theory:

Inside red blood cells, the malarial parasite must break down hemoglobin to satisfy its need for amino acids, which create proteins for the parasite. Hemoglobin is composed of a heme unit (not used by the parasite) and a protein unit (used by the parasite). Because heme is toxic, malaria biocrystalizes heme to form a structure called hemozoin, which is non-toxic, to avoid toxicity from this molecule.

Hydroxychloroquine sulfate is responsible for preventing the heme biocrystallization, leading to heme accumulation in the parasite. Heme is cytotoxic so that it will lead to the death of the parasite.

Hydroxychloroquine sulfate coronavirus

Some studies found that hydroxychloroquine sulfate is effective in killing the coronavirus in vitro. Also, many countries initially started using hydroxychloroquine to treat hospitalized cases with COVID-19 (March 2020). From April to June 2020, there was an emergency use authorization for hydroxychloroquine use in the United States.

On 24 April 2020, however, the FDA, citing the risk of abnormal heart rhythm problems, posted a caution against the use of hydroxychloroquine in COVID-19 patients outside the hospital setting or a clinical trial.

Finally, hydroxychloroquine use was withdrawn as a possible treatment for COVID-19 patients, as studies found that it adds NO BENEFIT for hospitalized severe COVID-19 and INEFFECTIVE drug for COVID-19.
