title: A mathematical transcription of a current problem in physiology.
abstract: The pre-Hilbert space of normal and pathological states of a living organism is built and a set of functions of medical interest are defined on it. Thus we put in mathematical terms the pathological of a state, the drug, the treatment, the length and the therapeutical effect of a treatment and the therapeutical efficiency of a drug.
