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. Product Usage Information. Chloroquine is supplied as a lyophilized powder. For a 50 mM stock, reconstitute the 150 mg in 5.82 ml sterile dH 2 O. First add 1 ml dH 2 O to the tube containing the chemical, vortex, and dispense into a new, larger tube. Repeat this action two or three more times to transfer any residual material. Both adults and children should take one dose of chloroquine per week starting at least 1 week before. traveling to the area where malaria transmission occurs. They should take one dose per week while there, and for 4 consecutive weeks after leaving. The weekly dosage for adults is 300mg base 500mg salt.

Peak plasma concentration is reached 1.5 to 3 hours after ingestion. Distribution by route of exposure Protein binding 5O to 65%. Chloroquine accumulates in high concentrations in kidney, liver, lung and spleen, and is strongly bound in melanin-containing cells eye and skin.

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.
