Question:
Volume of distribution (Vd)
Answer:
amount of drug divided by concentration
A large Volume of distribution may indicate that the drug distributes
extensively into the body.
Vd is a theoretical fluid volume necessary to contain the total amount of a
drug at the same concentration observed in the plasma.
,Sample Question: In renal failure would the Vd be increased or decreased?
Answer: Increased because of fluid retention
Question:
Distribution
Answer:
Plasma protein binding. Cannot leave the circulation easily. Free (unbound)
crosses membranes. Two drugs that are both highly protein bound will
compete with each other. The unbound fraction goes through metabolism
and is responsible for the pharmacologic effects. Drugs that are highly protein
bound and have a narrow therapeutic index can be dangerous because margin
of error between therapeutic and toxic is narrow.
Rapid weight loss may result in drugs being released from fat cells
Question:
Metabolism
Answer:
Mostly in the liver. Biotransformation or change it to inactive form or make it
more water soluble to facilitate excretion. This transformed substance is
called the metabolite. The rate of metabolism is affected by age, liver and
drug tolerance (Body may produce more enzymes and the liver becomes faster
at breaking that particular drug down)
