Description

Chloroquine (brand name Aralen) is indicated for the suppressive treatment and for acute attacks of malaria due to P. vivax, P.malariae, P. ovale, and susceptible strains of P. falciparum. The drug is also indicated for the treatment of extraintestinal amebiasis. In addition, chloroquine is in clinical trials as an investigational antiretroviral in humans with HIV-1/AIDS and as a potential antiviral agent against chikungunya fever. The mechanism of plasmodicidal action of chloroquine is not completely certain. However, is existed theory, that like other quinoline derivatives, it is thought to inhibit heme polymerase activity. The heme moiety consists of a porphyrin ring called Fe(II)-protoporphyrin IX (FP). To avoid destruction by this molecule, the parasite biocrystallizes heme to form hemozoin, a non-toxic molecule. Chloroquine enters the red blood cell, inhabiting parasite cell, and digestive vacuole by simple diffusion. Chloroquine then becomes protonated (to CQ2+), as the digestive vacuole is known to be acidic (pH 4.7); chloroquine then cannot leave by diffusion. Chloroquine caps hemozoin molecules to prevent further biocrystallization of heme, thus leading to heme buildup. Chloroquine binds to heme (or FP) to form what is known as the FP-Chloroquine complex; this complex is highly toxic to the cell and disrupts membrane function.

The drug is also indicated for the treatment of extraintestinal amebiasis. ARALEN does not prevent relapses in patients with vivax or malariae malaria because it is not effective against exoerythrocytic forms of the parasite, nor will it prevent vivax or malariae infection when administered as a prophylactic. It is highly effective as a suppressive agent in patients with vivax or malariae malaria, in terminating acute attacks, and significantly lengthening the interval between treatment and relapse. In patients with falciparum malaria it abolishes the acute attack and effects complete cure of the infection, unless due to a resistant strain of P. falciparum. Launch Date 1949

Sample Use Guides

In Vivo Use Guide

The dosage of chloroquine phosphate is often expressed in terms of equivalent chloroquine base. Each 500 mg tablet of ARALEN (chloroquine phosphate) contains the equivalent of 300 mg chloroquine base. In infants and children the dosage is preferably calculated by body weight. Malaria: Suppression—Adult Dose: 500 mg (= 300 mg base) on exactly the same day of each week. Pediatric Dose: The weekly suppressive dosage is 5 mg calculated as base, per kg of body weight, but should not exceed the adult dose regardless of weight. If circumstances permit, suppressive therapy should begin two weeks prior to exposure. However, failing this in adults, an initial double (loading) dose of 1 g (= 600 mg base), or in children 10 mg base/kg may be taken in two divided doses, six hours apart. The suppressive therapy should be continued for eight weeks after leaving the endemic area. For Treatment of Acute Attack. Adults: An initial dose of 1 g (=600 mg base) followed by an additional 500 mg (= 300 mg base) after six to eight hours and a single dose of 500 mg (= 300 mg base) on each of two consecutive days. This represents a total dose of 2.5 g chloroquine phosphate or 1.5 g base in three days. The dosage for adults of low body weight and for infants and children should be determined as follows: First dose: 10 mg base per kg (but not exceeding a single dose of 600 mg base) Second dose: (6 hours after first dose) 5 mg base per kg (but not exceeding a single dose of 300 mg base) Third dose: (24 hours after first dose) 5mg base per kg Fourth dose: (36 hours after first dose) 5 mg base per kg For radical cure of vivax and malariae malaria concomitant therapy with an 8-aminoquinoline compound is necessary. Extraintestinal Amebiasis: Adults, 1 g (600 mg base) daily for two days, followed by 500 mg (300 mg base) daily for at least two to three weeks. Treatment is usually combined with an effective intestinal amebicide.

Route of Administration: Oral

In Vitro Use Guide

Chloroquine inhibited mouse colon cancer cell line CT26 cells proliferation by concentration- and time-dependent manner. This effect was associated with apoptosis induction and decreased level of phosphorylated p42/44 mitogen-activated protein kinase and phosphorylated Akt. The cytotoxicity of chloroquine on CT26 cells was determined by the MTT assay. Cells were seeded in 96-well plates at the density of 2000/well and cultured for 24 hr, followed by chloroquine treatment (100, 50, 25, 12.5, 6.25, and 3.125 μ mol/L) for 24, 48, and 72 hr, respectively.
