What is biological half-life also called?
What is biological half-life?
The time it takes for a substance to lose one‐half of its pharmacological, physiological, or radiological activity.
What is the formula for biological half-life?
Give a simple mathematic pharmacokinetic elimination model
C=C0e-Kt for t≥0, K>0
- C denotes the plasma/serum drug concentration at time t (measured in mass/volume; e.g. mg/mL);
- C0 denotes the initial plasma/serum drug concentration
- K denotes the elimination rate constant (measured in reciprocal time; e.g. h‐1, min‐1, s‐1)
- t denotes time (e.g. hours, minutes, seconds).
If C=C0e-Kt, what does lnC equal?
lnC = ln(C0)-Kt
What is termination of action?
The time at which the drug concentration in the plasma/serum falls below the minimum level of the therapeutic range.
What is the formula for a logistic function?
Where L=carrying capacity
L/2=the inflection point
How will k effect a logistic model?
A large k will show a large surge in the data, a small k will show a gradual rise
What does a dose-response curve plot?
The intensity (usually scaled as a percentage of the maximum response) of physiological response to a drug as a function of the dose administered.
