Description
Curator's Comment: description was created based on several sources, including https://www.drugbank.ca/drugs/DB00613 | https://www.drugs.com/international/amodiaquine.html | https://www.ncbi.nlm.nih.gov/pubmed/9825729 | https://www.ncbi.nlm.nih.gov/pubmed/22949374 | https://www.ncbi.nlm.nih.gov/pubmed/18855526

Amodiaquine is a medication used to treat malaria, including Plasmodium falciparum malaria when uncomplicated. The mechanism of plasmodicidal action of amodiaquine is not completely certain. Like other quinoline derivatives, it is thought to inhibit heme polymerase activity. This results in accumulation of free heme, which is toxic to the parasites. The drug binds the free heme preventing the parasite from converting it to a form less toxic. This drug-heme complex is toxic and disrupts membrane function. The side effects of amodiaquine are generally minor to moderate and are similar to those of chloroquine. Rarely liver problems or low blood cell levels may occur. When taken in excess headaches, trouble seeing, seizures, and cardiac arrest may occur. After oral administration amodiaquine hydrochloride is rapidly absorbed,and undergoes rapid and extensive metabolism to desethylamodiaquine which concentrates in red blood cells. It is likely that desethylamodiaquine, not amodiaquine, is responsible for most of the observed antimalarial activity, and that the toxic effects of amodiaquine after oral administration may in part be due to desethylamodiaquine.

Curator's Comment: Although in use for more than 40 year, there exists little information regarding the disposition of amodiaquine in man. Chloroquine, a 4-aminoquinoline derivative which resembles amodiaquine structurally, is widely distributed into the body tissues, especially in liver, spleen, kidney, lungs, brain, and spinal cord.

Sample Use Guides

In Vivo Use Guide
For the treatment of acute malarial attacks in non-immune subjects: 600 mg of the base, followed by 200 mg after 6 hours, then 400 mg daily on each of the subsequent two days. Doses may be taken with meals to lessen gastric upset.
Route of Administration: Oral
In Vitro Use Guide
The FCR3 strain of Plasmodium falciparum was synchronized and cultivated to the trophozoite stage. Synchronized cultures were seeded at the ring stage and allowed to grow for another 20 hr until most parasites reached the trophozoite stage; parasitemia and cell number were determined, and cultures were cultured 6 drug for 1,2,3 and 4 h. One milliliter of culture was washed twice in wash medium (culture medium without plasma, 37°) to remove the drug, and cells were seeded in 24-well culture plates in full culture medium supplemented with 5 mCi/mL of [3H]hypoxanthine. After 4 hr of further cultivation, triplicate samples were transferred into 96-well plates, and parasiteassociated radioactivity was determined using the Filtermate/Matrix 96 Direct Beta counter. Inhibition of parasite growth was calculated compared to untreated controls.
