Chloroquine and hydroxychloroquine are anti-malarial medications also used against some auto-immune diseases. [64] Chloroquine, along with hydroxychloroquine, was an early experimental treatment for COVID-19. [65] Neither drug has been useful to prevent or treat SARS-CoV-2 infection.
Quinine, like chloroquine, inactivates enzymes in the lysosomes of cells and has an anti-inflammatory effect, hence its use in the treatment of rheumatoid arthritis. However, inactivation of these enzymes can also cause abnormal accumulation of glycogen and phospholipids in lysosomes, causing toxic myopathy. It is possible this action is the ...
This includes the treatment of malaria due to Plasmodium falciparum that is resistant to chloroquine when artesunate is not available. [5] [6] While sometimes used for nocturnal leg cramps, quinine is not recommended for this purpose due to the risk of serious side effects. [5] It can be taken by mouth or intravenously. [5]
Chloroquine also has a significant anti-pyretic and anti-inflammatory effect when used to treat P. vivax infections, and thus it may still remain useful even when resistance is more widespread. According to a report on the Science and Development Network website's sub-Saharan Africa section, there is very little drug resistance among children ...
Among the quinoline alkaloids are the cinchona alkaloids quinine and quinidine, which are important due to their therapeutic potential, furthermore cinchonine and cinchonidine, as well as some furoquinoline alkaloids and acridine alkaloids.
Hypersensitivity to quinine, mefloquine, quinidine, or dextromethorphan/quinidine with a history of thrombocytopenia, hepatitis, bone marrow depression or lupus-like syndrome induced by these drugs; QT interval, prolonged or congenital long QT syndrome or a history suggesting torsades de pointes
Quinidine's effect on I Na is known as a 'use dependent block'. This means at higher heart rates, the block increases, while at lower heart rates, the block decreases. The effect of blocking the fast inward sodium current causes the phase 0 depolarization of the cardiac action potential to decrease (decreased V max).
The disease is named because it is a porphyria that often presents with skin manifestations later in life. The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of the body's organs. It is a component of hemoglobin, the molecule that carries oxygen in the blood.
