Recommended dose is 50 to 150 mg/kg/day every 6 hours
Weight of patient in kg is 73.5kg
To find range -
If in 1kg dose recommended is 50mg /day
Then in 73.5 kg dose recommended is 50× 73.5 = 3675mg /day
If in 24 hours (1 day) dose is 3675
Then in every 6 hours dose will be = 3675× 6/24 = 918.75mg in one dose ( round off will be 919mg per dose)
Also if in 1kg dose recommended is 150mg/day
Then in 73.5kg dose recommended is = 150×73.5 = 11025 mg /day
If in 24 hours dose is 11025mg /day for this patient
Then in every 6hours dose is = 11025 ×6/24 =
2756.25 mg/ dose ( round off is 2756 mg)
Thus the range in mg patient could take per dose = 919 - 2756 mg /dose or 918.75 - 2756.25 mg/dose
b) if 1 tablet contains = 250 mg or
250 mg drug is in 1 tablet , then
In 918.75mg drug is in = 1×918.75/ 250 = 3.6 ( 3 and half tablets)
Also if 250 mg drug is in 1 tablet
Then in 2756.25 mg drug number of tablets will be = 1 × 2756.25/ 250 = 11 tablets
Thus range of tablets per dose for patient will be 3 and half tablets to 11 tablets.
