Assume you have a med with a 72 hour half life, but that is dosed daily. How much elimination occurs each day of the drug, and what is the steady state dose compared to the daily dose?(adsbygoogle = window.adsbygoogle || []).push({});

Is it just a linear decrease, so you take 50/72= 0.667, and multiply 0.667x24= 16 which means everyday 16% of the drug in your system is destroyed, and you have 100/16=6 so 6 times as much as the daily dose in your system at any given time (ie if you take 10mg a day you have a steady state level of 60mg in your body)?

If drug half life is exponential I don't know how to solve it.
