questionhint
drugs move most rapidly and in greater concentrations to compartments with good ____ perfusion
the random movement of drug molecules
does physical transport require energy?
biotransformation occurs primarily in what organ?
body's ability to change the original drug into a form that can be eliminated
drug that occupies the receptor sand produces no cellular effectite
a special 'carrier molecule' in the cell membrane moves the drug across the membrane
some drugs bind to large _____ in the bloodstream
cell eating
pH where drug molecules are half ionized and half non-ionized
factor that influences blood levels of a drug: _____ of drug absorbed
measure of the acidity or alkalinity of the drugs environment
tablets, granules, or powders cannot be absorbed until they _______ into smaller particles
T or F: different compartments of the body have different pHs
what type of drugs pass through the cell membranes?
does active transport require energy?

cell drinking
questionhint
endothelial cells in the brain have ____ junctions
the dose of highly protein-bound drugs should be _____ if diseases are present that cause low plasma protein levels
sustained-release tablets dissolve fast or slow?
If a molecule changes to primarily hydrophilic form, it may not be able to leave the cell; what is this called?
steady state= __ x half life
hydrophilic molecules dissolve in ____
molecules having a net positive or negative charge are ____

alkaline drugs are primarily in nonionized form in _____ environment
What makes it hard for drug molecules to get through to the brain?
does passive diffusion require energy?
lipophilic drugs are absorbed best _____
