Modelling Flashcards
What does Pharmacokinetics describe
Description of the temporal behavior of a drug concentration in the organism
Dynamic Processes in Body
Absorption
Distribution
Elimination
Zero & First Order Kinetics
Zero-order:
- Rate of concentration C is constant –> dC/dt = k
First-order:
- Rate of concentration change is directly proportional to the substances concentration –> dC/dt = - k*C
Two-Compartment Model with Single Dose
Single dose with 1st order absorption
–> Bateman function! = impulse response of a 2nd order system
Concentration-Effect Characteristic curve
2 Kennwerte:
1) Minimal effective concentration (MEC) –> bei 30%
2) Minimal toxic concentration (MTC) –> bei 75%
–> used for optimal adjustment of drug treatment
Name 4 energy forms
