    -Suppressive therapy should continue for 8 weeks after leaving the endemic area. Approved indication: For the suppressive treatment of malaria due to Plasmodium vivax, P malariae, P ovale, and susceptible strains of P falciparum CDC Recommendations: 300 mg base (500 mg salt) orally once a week Comments: -For prophylaxis only in areas with chloroquine-sensitive malaria -Prophylaxis should start 1 to 2 weeks before travel to malarious areas; should continue weekly (same day each week) while in malarious areas and for 4 weeks after leaving such areas.

    Like chloroquine phosphate, USP, PLAQUENIL is highly active against the erythrocytic forms of P. vivax and malariae and most strains of P. falciparum but not the gametocytes of P. falciparum. PLAQUENIL does not prevent relapses in patients with vivax or malariae malaria Employ the developed method for analysis of chloroquine phosphate in pharmaceutical dosage forms, and to compare between the developed method and the official methods for analysis of chloroquine phosphate formulations. The zero order absorption and first derivative spectra were measured for chloroquine phosphate Oct 06, 2015 The fluorescence extinction coefficient FEC was calculated to be 35,215 RFU/μM for the FRET substrate. This FEC value was used to determine the amount of the product formation in each reaction. The kinetic parameters K m and k cat /K m were calculated as 1.26 ± 0.34 μM and 1.11 × 10 3 M −1 sec −1 respectively Fig. 3D.

    Approved indication: For acute attacks of malaria due to P vivax, P malariae, P ovale, and susceptible strains of P falciparum CDC Recommendations: Chloroquine-sensitive uncomplicated malaria (Plasmodium species or species not identified): 600 mg base (1 g salt) orally at once, followed by 300 mg base (500 mg salt) orally at 6, 24, and 48 hours Total dose: 1.5 g base (2.5 g salt) Comments: -For the treatment of uncomplicated malaria due to chloroquine-sensitive P vivax or P ovale, concomitant treatment with primaquine phosphate is recommended. 60 kg or more: 1 g chloroquine phosphate (600 mg base) orally as an initial dose, followed by 500 mg chloroquine phosphate (300 mg base) orally after 6 to 8 hours, then 500 mg chloroquine phosphate (300 mg base) orally once a day on the next 2 consecutive days Total dose: 2.5 g chloroquine phosphate (1.5 g base) in 3 days Less than 60 kg: First dose: 16.7 mg chloroquine phosphate/kg (10 mg base/kg) orally Second dose (6 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Third dose (24 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Fourth dose (36 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Total dose: 41.7 mg chloroquine phosphate/kg (25 mg base/kg) in 3 days Comments: -Concomitant therapy with an 8-aminoquinoline compound is necessary for radical cure of malaria due to P vivax and P malariae.
