Day 2: (24 hours later) the amount left in his body is 300 mg (day 2 min) because

24 hours has passed--one 1/2 life--therefore the pt has excreted 1/2 of the initial

amount.


THEN the pt takes his 2nd dose of 600 mg on DAY 2-resulting in a max dose of 900

(300 mg left in body + 600 mg of 2nd dose).


DAY 3: starts off with 450 mg (1/2 of the 900 mg in pt's system) and after taking

the day 3 600 mg dose, the pt now has a total of 1050 mg.

_________induces it's own metabolism, hastening excretion and shortening it's

half life


A. Carbamazepine (Tegretol)



*this effect begins to "rev up" after 2-4 weeks--which is why a carbamazepine

level is so important on obtaining 1-2 months after starting Tegretol.


Carbamazepine (Tegretol) level should be checked how soon after starting to

take this med?


1-2 months due to Tegretol inducing it's own metabolism, hastening excretion and

shortening it's half life.

render it therapeutically inactive?
