General Principles of pharmacology

- various types of rug interactions
- factors influencing drug response
Absorption
The transfer of the drug from the body fluids to the tissues
What route of drug administration produces the most rapid response
than any other method
IV
Pinocytosis
Cells engulf the drug particle across the cell membrane. pack man…
Diffuse across a membrane from area of
higher concentration to an area of lower concentration
Passive absorption
Carrier molecule such as a protein or enzyme actively moves the drug across the membrane.
Active absorption
Drug levels in blood to produce desired effect.
Therapeutic effect
Chemical reaction by with liver converts drug to inactive compound

medication that is metabolized by the liver or a _____
medication that is not metabolized by the liver.
Lower, Different
Elimination of drugs from the body.
