,- To interfere with the functioning of foreign cells
What is the process of pharmacokinetics? (ADME) - 🧠 ANSWER
✔✔Absorption
Distribution
Metabolism
Excretion
What is absorption? - 🧠 ANSWER ✔✔- The movement of the drug from the
site of administration into the bloodstream
- What happens to a drug from the time it is introduced to the body until it
reaches the circulating fluids and tissues
What is distribution? - 🧠 ANSWER ✔✔The movement of the drugs into the
cells and body tissues
What is biotransformation (metabolism)? - 🧠 ANSWER ✔✔- The conversion
of the drug into another substance or substances

What factors affect absorption of medications? - 🧠 ANSWER ✔✔- Dosage
form
- Route of administration
- Administration site blood flow
- GI function
- Presence of food or other drugs

, What is protein binding? How does it relate to distribution? - 🧠 ANSWER
✔✔Protein-bound drugs can't pass through capillary walls until bonds
dissolve, dosages calculated based on the protein-binding characteristics,
Low "albumin level", more unbound, more toxicity
What is the blood brain barrier? How does it relate to distribution? - 🧠
ANSWER ✔✔Cells in the capillary walls are tightly packed, keeps toxins
and poisons out of the brain
Placenta membrane and lactation, how does it relate to distribution? - 🧠
ANSWER ✔✔Not a barrier like the blood-brain barrier, any drug that can
pass through a membrane can pas through the placenta, always ask if a pt
is pregnant or lactating
What is the hepatic microsomal (P-450 enzyme) system? - 🧠 ANSWER
✔✔Liver metabolism predominately achieved by specific liver enzymes
called cytochrome P-450
What is pharmacogenomics? - 🧠 ANSWER ✔✔Genotyping for allleles that
alllow for abnormal metabolism of certain drugs by the P-450 sytem
What is the process of excretion? - 🧠 ANSWER ✔✔Elimination of a drug or
its metabolites from the body, most commonly via kidneys (urine)
