involves
absorption from the administration site either directly or indirectly in the
blood plasma Ans: Pharmacokinetic absorption
reversibly or irreversibly move from the bloodstream into the interstitial
and intracellular fluid Ans: Parmacokinetic distribution
biotransformed via hepatic metabolism or by other tissue Ans:
Pharmacokinetics metabolism
1. highest bioavailability
2. places entire does into venin thus bypassing absorption
3. avoids hepatic first pass metabolism in the liver Ans: Intravenous
medications
usually reached within 4-5 half lives of the drug Ans: steady state
medication
1.the time required for the elimination process to reduce 2.the
concentration of the drug to one half what it was at initial administration
3.determines drug frequency

5. constant first order pharmacokinetics of a drug Ans: drug half life
, Page | 2
drug is metabolized at a constant rate per unit Ans: zero order
(nonlinear)
metabolizes 50% drugs
inhibit: grapefruit juice
- increase drug -> adverse effects
may have enhanced activity with any other CYP3A4 Ans: CYP3A4

while lab testing Ans: Six steps in drug development process
1.Institute of Safe mediation Practice
2. Institute of Medicine
3. Joint commission
4.National Coordinating Council form mediation error reporting and
prevention
5. Food and Drug Administration (safe use initiative) Ans: organizations
for medication safety
1.Also known as a side effect, an undesirable reaction that accompanies
the principal response for which the drug was taken include allergic
reactions and adverse drug effects
, Page | 3
2. Either pharmacological or idiosyncratic
3. 85-90% of ADRs are pharmacological
4. Reporting is not mandated by FDA thus are not commonly reported
5. usually preventable occur in hospital and nursing homes due to med

secondary may be caused by CKD Ans: Essential vs Secondary HTN
use: angina pectoris
action: dilate veins and arteries and thereby reducing ischemia and
relieving pain by decreasing myocardial O2 consumption
