Most of the medications that we ingest are removed from our bodiesvia a first order process. It is the aim of the physician to keepthe concentration of medication (in our body) more or less constantover the treatment period. If a 10% variation in concentration isthe largest acceptable swing, and if the patient is required totake two doses of the medication per day (i.e. once every 12hours), what is the largest acceptable rate constant for the disappearance of the medication and what is the associated half-life?
