The bioavailability of chloroquine in healthy adult volunteers

It is recommended that for individuals weighting 45 to 55kg a dose of chloroquine of 600mg on first day 300mg on second day and 150mg on third day would give desired therapeutic non-toxic levels whereas for heavier individuals (80-90kg) the appropriate dosage would be 5 tablets (750mg) first day; 4 tablets (600mg) second day and 3 tablets (450mg) on third day
