samkhat Posted March 4, 2009 Share Posted March 4, 2009 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 Quote Link to comment Share on other sites More sharing options...
aflexatabs Posted March 5, 2009 Share Posted March 5, 2009 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! Quote Link to comment Share on other sites More sharing options...
