Question
4) A 45-year old woman weighing 68 kg is admitted to hospital after a drug overdose.
A toxic plasma concentration of 264 mg/mL is recorded on admission. After 35
hours, a plasma concentration of 8.25mg/ml is recorded.
Given this information, calculate the half life for this drug.
(Assume the distribution is complete and that the elimination is described by a first-
order process.)
