Thank you dr
But i think there’s something you have to clarify, you said (t 1/2 )1 is 50% and this is correct, then you said (t1/2)2 is 25 but its 75% eliminated not 25
And (t1/2)3 it should be 87.5% not 12.5 and so on .
Many thanks

What is terminal half life ?

[@JunaidAsgharPhD]

Terminal half life refers to the time it takes for the concentration of a drug in the body to decrease by half during the elimination phase. It represents the final phase of drug elimination from the body.
