Dark-skinned persons may experience generalized pruritus that is not indicative of drug allergy. Retinal toxicity that may occur with long-term high doses of chloroquine used in the treatment of other diseases is extremely unlikely with chloroquine given as a weekly malaria chemosuppressive agent. Small bowel obstruction bowel obstruction take hydroxychloroquine Icd 10 code for plaquenil use Hydroxychloroquine prophylaxis Chloroquine binds to heme or FP to form the FP-chloroquine complex; this complex is highly toxic to the cell and disrupts membrane function. Action of the toxic FP-chloroquine and FP results in cell lysis and ultimately parasite cell autodigestion. In essence, the parasite cell drowns in its own metabolic products. Chloroquine works best when you take it on a regular schedule. For example, if you are taking it once a week to prevent malaria, it is best to take it on the same day of each week. Make sure that you do not miss any doses. If you have any questions about this, check with your doctor. Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. Although the mechanism of action is not fully understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin. Because insufficient drug is excreted in breast milk to protect the infant, nursing infants should be given chloroquine. Chloroquine use is suitable for people of all ages and for pregnant women.

Chloroquine acts exclusively in the erythrocyte stage of malaria parasites. The antimalarial mechanism of action from chloroquine has not been fully elucidated. Many theories have been developed to elucidate the chloroquine mechanism of action, including DNA binding and inhibition of various enzymes and/or transporters. Chloroquine Phosphate. Chloroquine is used to prevent or treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. Chloroquine phosphate is a 4-aminoquinolone that acts by inhibiting heme polymerase. 198 Chloroquine is well tolerated and in appropriate doses may be safely used by young children and pregnant women. 199 Transient nausea or vomiting is seen in a small proportion of individuals and may usually be reduced by taking the drug with food.
