How can 1/2 life be SAME for DIFF concentrations?

Posted by Janelle on April 5, 2002, at 14:45:06

How can the number of half lives required to eliminate a drug (5-7 half lives and it's gone from body) be the SAME for DIFFERENT concentrations of the drug?
Meaning, wouldn't a drug with a 100 mg/l concentration have fewer half-lives than one with say 350 mg/l concentration?
I don't get this! Please help! Thanks!
