Question

Chloroquine is used to prevent or suppress malaria in patients. Two weeks before the patient is potentially exposed to malaria, and for six weeks after the patient has returned, chloroquine is administered once a week (on the same day) at a dose of 500 mg. Suppose the patient spends 13 weeks in an area in which there is high exposure to malaria. How many 250-mg tablets of chloroquine will be administered altogether?

Answer 1

Chloroquine is given in Malaria prophylaxis treatment to prevent or suppress it.To be taken before 1 to 2 weeks before being exposed and continue throughout the stay ,then for 4 weeks. It should be taken once a week on the same time probably.

Here the patient spends about 13 weeks which is a high exposure area, so the patient has to taken 13 doses totally ,1 per week for 13 weeks

Therefore

13 weeks=13 doses

1 dose=500mg

So 13 dose will be 500×13=6500mg

Now in simple to calculate the number of tablets

availability is 1 tablet =250mg,so in a day for a dose of 500mg ,2 tablet has to be taken

Therefore for 13 days (13×2)=26 tablets

Ans:Altogether 26 tablets will be administered
