License: CC BY 2.5Treatment of malaria is aimed at killing the schizonts by one or more mechanisms. Resistance occurs when the parasite develops mechanisms that reduce the effects of the antimalarials or bypasses the mechanisms of the drug. Plaquenil brand name vs generic Plaquenil generic vomiting 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. Mechanism of action As with chloroquine, quinine interferes with heme polymerization. Clinical uses. Multidrug-resistant malaria treatment; Severe malaria, including cerebral malaria intravenous quinine is the drug of choice. Mechanism of Action Chloroquine, a 4-aminoquinoline, is an anti-protozoal agent. The precise mechanism by which Chloroquine exhibits activity is not known. Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. It can also inhibit certain enzymes by its interaction with DNA. Monotherapy should be avoided to prevent drug considered a superior antimalarial drug to quinine. Effects of the antimalarial drug primaquine on the dynamic structure of lipid model membranes. The American journal of tropical medicine and hygiene, 77(6 Suppl), 29–35. Resistance is a major problem in some parts of the world, e.g., Africa and Southeast Asia; therefore, newer drugs are utilized.

It is believed to reach high concentrations in the vacuoles of the parasite, which, due to its alkaline nature, raises the internal pH. Antimalarial medication - Wikipedia. Chloroquine - FDA prescribing information, side effects.. Aralen chloroquine Malaria Drug Side Effects & Dosage. For treatment of malaria Adults—At first, 1000 milligrams mg once a day. Then, 500 mg 6 to 8 hours after the first dose, and 500 mg on the second and third days of treatment. Adults with low body weight and children—Dose is based on body weight and must be determined by your doctor. Although these drugs are known to accumulate by a weak base mechanism in the acidic food vacuoles of intraerythrocytic trophozoites and thereby prevent hemoglobin degradation from occurring in that organelle, the mechanism by which their selective toxicity for lysosomes of malaria trophozoites is achieved has been subject to much discussion and argument. Chloroquine is thought to exert its antimalarial effect by preventing the polymerization of toxic heme released during proteolysis of hemoglobin in the Plasmodium digestive vacuole. The mechanism of this blockade has not been established.
