contraindication to administer that drug.
What is the drugs half-life? - CORRECT ANSWERS Half-life specifically
means the amount of time it takes for an administered drug to be halfway
cleared from the system.
Peak of action: - CORRECT ANSWERS the time between drug
administration and maximum concentration of drug in the blood stream.
Best therapeutic effect.
Duration of action: - CORRECT ANSWERS the time between onset of action
and metabolism of drug below the minimum needed for an effect. The
length of time you have the drug in your system.
According to the WHO what is the first step in the prescribing process? -
CORRECT ANSWERS The first step is to define the patient's problem
The second step is to - CORRECT ANSWERS specify the therapeutic

Step 6 of the WHO approach: - CORRECT ANSWERS Monitor the treatment
Phase 1 of drug development: - CORRECT ANSWERS The drug is tested on
healthy volunteers
Phase 2 of drug development: - CORRECT ANSWERS trials with people
who have the disease for which the drug is thought to be effective
Phase 3 of drug development: - CORRECT ANSWERS Large numbers of
patients in medical research centers receive the drug in phase 3. This larger
sampling provides information about infrequent or rare adverse effects.
The FFA will approve a new drug application if phase 3 studies are
satisfactory.
Phase 4 of drug development: - CORRECT ANSWERS This phase is
voluntary and involves postmarket surveillance of the drug's therapeutic
effects at the completion of phase 3. The pharmaceutical company receives
reports from doctors and other health care professionals about the
therapeutic results and adverse effects of the drug. Some medications, for
example, have been found to be toxic and have been removed from the
market after their initial release.
Explain first pass metabolism - CORRECT ANSWERS much of the drug is
lost in the absorption process. The liver metabolizes many drugs, thus
reduces the bioavailabilty of the drug.
What is the fasted route of absorption: - CORRECT ANSWERS The fastest
route of absorption is inhalation, and not as mistakenly considered the IV
administration.

Why does the GI tract take longer to absorb? - CORRECT ANSWERS The GI
tract is lined with epithelial cells; drugs must permeate through these cells
in order to be absorbed into the circulatory system.
What is One particular cellular barrier that may prevent absorption of a
given drug? - CORRECT ANSWERS the cell membrane. Cell membranes are
essentially lipid bilayers which form a semipermeable membrane. Pure
lipid bilayers are generally permeable only to small and uncharged solutes,
hence whether or not a molecule is ionized will affect its absorption, since
ionic molecules are charged.
What is solubility? - CORRECT ANSWERS Solubility favors charged species,
permeability favors neutral species. Some molecules have special exchange
proteins and channels to facilitate movement from the lumen into the
circulation.
Why does absorption occur at a slower rate for oral, IM, SQ routes? -
CORRECT ANSWERS Absorption occurs at a slower rate because the
complex membrane systems of GI mucosal layers, muscle, and skin delay
drug passage.
The ability of a drug to cross a cell membrane depends on: - CORRECT
ANSWERS whether the drug is water or lipid (fat) soluble. Lipid-soluble
drugs easily cross through cell membranes; water-soluble drugs can't.
Lipid-soluble drugs can also cross the blood-brain barrier and enter the
brain.
As a drug travels through the body, it comes in contact with? - CORRECT
ANSWERS proteins such as the plasma protein albumin. The drug can
remain free or bind to the protein. The portion of a drug that's bound to a
protein is inactive and can't exert a therapeutic effect. Only the free, or
unbound, portion remains active. A drug is said to be highly protein-bound
if more than 80% of the drug is bound to protein.
