Please verify if it's correct.
looks ok to me
How do I solve for Cmax= 8.5/ e(-0.257 * (1-0.5))? Also, how would I input 'e' in my calculator?
Sorry wrong spot
To calculate the single dose, you need to divide the total amount prescribed (750mg) by the strength of each tablet (250mg).
a) Single dose calculation:
750mg ÷ 250mg = 3 tablets
You are correct. The single dose would be 3 tablets.
To calculate the 24-hour dose, you multiply the single dose by the number of doses taken in 24 hours, which in this case is twice a day (BID).
b) 24-hour dose calculation:
Single dose (3 tablets) × Number of doses per day (2) = 6 tablets
6 tablets × Strength of each tablet (250mg) = 1500mg
Again, you are correct. The 24-hour dose would be 1500mg.
So your answers are indeed correct:
a) The single dose is 3 tablets.
b) The 24-hour dose is 1500mg.
