The Medicine Model for Different Time Intervals and the Weight Change

A medication method is given for different time interval and the weight change. Due to the patient's weight is different, and the time intervals of the same medication are not easy to realize, and the velocity of the metabolism is not the same at night and day. And the absorbing velocity is also different, so the dosage of the drug should be different at different time points. According to the rate of change of the concentration of drug and dosage is in proportion, that is the modeling mechanism, two mathematical models are established for the daytime and nighttime drug concentrations. Through solving and analysis of being the model, the following conclusions are obtained: patients in the morning dose is relatively large, and at noon and in the evening is the same but less than the morning, as well as the weight and the dosage of the drug dose relationship. Thus according to the model manufacture different dose of pills, the pharmaceutical factory can convenient to patients taking. According to this method, the doctor also can prescribe for the patients of different dose prescription. The patients will be in the shortest possible time to heal, but not of physical harm.
