Calculating half life

Hi guys

I really need the formula for calculating T1/2 when peak and trough values are given .I have this formula

K = (ln C peak )- (log Ctrough) /dosing interval

 

then putting this K in

T1/2 = 0.693/k

 

but in the naplex our calculator does not have any log key So how can we calculate T1/2 with peak and trough given ? Any other formula???

 

Please help me out here.

Thanks

I don't completely believe that they would give you this type of questions. But if they do, I am pretty sure they would only give easy numbers to calculate. Like the Log of 100 which is 2, 10 is 1 and so on. Those are just easy and quick to recall. YOu dont even need a calculator to solve the log of 100 and 10. Focus more on dosage calculation of all types, doses, tpn, kcal, meq, milliosmoles, compounding, ratio and proportion, %, and so on. In my exam I was able to use the square root function of the calculator. Goodluck!
