    Rapid diagnostic assays for Pf CRT mutations are already employed as surveillance tools for drug resistance. Here, we review recent field studies that support the central role of Pf CRT mutations in chloroquine resistance.

    Each tablet contains 500 mg of Chloroquine phosphate USP, equivalent to 300 mg Chloroquine base. Inactive Ingredients colloidal silicon dioxide, dibasic calcium phosphate, hydroxypropylmethylcellulose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate80, pregelatinized starch. Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. Although the mechanism is not well understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite. Chloroquine resistance is widespread in P. falciparum and is reported in P. vivax. Prior to initiation of chloroquine for prophylaxis, it should be determined if chloroquine is appropriate for use in the region to be visited; do not use for malaria prophylaxis in areas where chloroquine resistance occurs.

    Recognition of the value of chloroquine was delayed, and it was not brought forward until it was reevaluated in the United States and designated the drug of choice against malaria near the end of World War II [3]. These studies suggest chloroquine resistance arose in ⩾4 distinct geographic foci and substantiate an important role of immunity in the outcomes of resistant infections after chloroquine treatment. Investigation of the resistance mechanisms and of the role of immunity in therapeutic outcomes will support new approaches to drugs that can take the place of chloroquine or augment its efficiency Early in the 20th century, intense demands for an effective quinine substitute launched the discovery and evaluation of a series of organic compounds (beginning with methylene blue), which led to pamaquine and quinacrine after World War I and ultimately produced chloroquine in 1934 [1, 2].

    Opment of resistance to antimalarial drugs. To date, drug resistance has only been documented in two of the four species, P. falciparum and P. vivax. 2.3 Diagnosis Table 1 Direct microscopic examination of intracellular parasites on stained blood films is the current stand-ard for definitive diagnosis in nearly all settings. An antimalarial and antiprotozoal agent, also used as a lupus erythematosus suppressant. 2. an antiamebic and antiinflammatory agent used in treatment of malaria, giardiasis, non-intestinal amebiasis, lupus erythematosus, and rheumatoid arthritis; used as the base, hydrochloride salt, or phosphate salt. P falciparum which is resistant to chloroquine—a pharmacologic ‘staple’ used to treat and as prophylaxis for visitors to malaria endemic regions of Africa. Mechanism of resistance Resistant strains of P falciparum do not concentrate chloroquine; resistance is reversed by verapamil, a calcium channel blocker.

    Plaquenil-Hydroxychloroquine sulfate 200mg FC Tabs - Summary. Hydroxychloroquine sulfate has been reported to increase plasma digoxin levels. Serum digoxin levels should be closely monitored in patients receiving concomitant treatment. Hydroxychloroquine sulfate may also be subject to several of the known interactions of chloroquine even though specific reports have not appeared.
