چکیده

This paper proposes a method for studying the toxicity of an anticancer drug with a delayed effect. The goal is to predict a dosage regimen with controlled toxicity. To this end, a semi-physiological model is used. A limit of toxicity is demonstrated, which is intrinsic to the model. It reduces the effect of high drug concentrations. This limit explains the mixed behaviour of the drug: time-dependence and concentration-dependence, according to the dose actually administered. A population analysis is performed to estimate the parameters of the model, and to predict a safe dosage regimen.

مروری بر فارماکوکنتیک و فارماکودینامیک وریکونازول

Voriconazole is an antifungal triazole, approved for management of invasive fungal diseases in patients. It is absorbed during two hours and its serum levels will be above 90%, based on the underlying factors, when the drug is administered orally. Voriconazole shows a propotional increase in an area under the plasma concentration-time curve (AUC), with increasing dose. Plasma protein binding of...

Explicit formulas for a continuous stochastic maturation model. Application to anticancer drug pharmacokinetics/pharmacodynamics

We present a continuous time model of maturation and survival, obtained as the limit of a compartmental evolution model when the number of compartments tends to infinity. We establish in particular an explicit formula for the law of the system output under inhomogeneous killing and when the input follows a time-inhomogeneous Poisson process. This approach allows the discussion of identifiabilit...

Making TDM work to optimize cancer chemotherapy: a multidisciplinary team approach.

Several factors can limit the use of therapeutic drug monitoring (TDM) for cancer chemotherapeutic agents, including poorly defined concentration-effect relationships for many antineoplastic agents. This is further complicated by cancer being a highly heterogeneous group of diseases, each of which may have a unique concentration-effect relationship for any given drug or drug combination. Noneth...

Pharmacokinetics and Pharmacodynamics of Gliclazide from Immediate and Modified Release Formulation Tablets in Rats

The objective of the study was to compare pharmacokinetic and pharmacodynamic parameters of gliclazide after administration of immediate (IR) and modified release (MR) tablets. The experiment included rats with both normoglyceamia and streptozocin (STZ)-induced hyperglyceamia. Several MR formulations were designed and in vitro drug release profile was assessed by a dissolution test. For the fur...
