    -Suppressive therapy should continue for 8 weeks after leaving the endemic area.

    Chloroquine is a lysosomotropic agent that prevents endosomal acidification 1. It accumulates inside the acidic parts of the cell, including endosomes and lysosomes. This accumulation leads to inhibition of lysosomal enzymes that require an acidic pH, and prevents fusion of endosomes and lysosomes. To examine the consequences of UPS buffering of luminal pH on endosome protein coat maturation, UPS 6.2 and UPS 4.4 were selected to study the recruitment of the Rab5 GTPase, which is a discriminating feature of early endosome pH 6.0–6.5 biogenesis, and LAMP2, which is a biomarker of lysosomes pH 4.0–4.5. Fluorescent dextran was used. Chloroquine is a weakly basic compound and is able to increase pH in endosome. We speculated that chloroquine prevented the disassembly of viral particles to release viral RNA from endosome to cytoplasm for replication.

    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.

    We review the available information on the effects of chloroquine on viral infections, raising the question of whether this old drug may experience a revival in the clinical management of viral diseases such as AIDS and severe acute respiratory syndrome, which afflict mankind in the era of globalisation. Unfortunately, Chloroquine, as well as other endosomal escape or endolytic agents, are often too toxic for use in preclinical models or eventual clinical trials of macromolecular therapeutics. Chloroquine is a 9-aminoquinoline known since 1934. Apart from its well-known antimalarial effects, the drug has interesting biochemical properties that might be applied against some viral infections. Chloroquine exerts direct antiviral effects, inhibiting pH-dependent steps of the replication of several viruses including members of the flaviviruses, retroviruses, and coronaviruses. Its best.
