内容介绍:The classic pharmacokinetic models assume that all patients perfectly follow dosing regimens during drug treatment, whereas the significant factor of patients ‘drug adherence does not take into account. In this talk, considering binomial distribution at each dosing event, we reformulate the classic compartment pharmacokinetic models in stochastic framework, and analyze their qualitative properties including the expectation and variance of the plasma concentration, existence of the limit drug distribution, stochastic stability such as recurrence and other important properties. In addition, the sensitivity of adherence-related parameters to the key values of expectation and variance is analyzed. Our findings can provide important theoretical guidance for the properties of drug concentration and help the design of the medication regimen. Moreover, our approach also provides the possibility for the further study of individual-based drug adherence for long term drug treatment and drug resistance development of many diseases such as HIV.
