CORRECT | GRADE A+!!
Pharmacokinetics - answer-Involves ADME (absorption, distribution, metabolism and
elimination).
Absorption: absorption from the administration site either directly or indirectly into the
blood/plasma.
Distribution: reversibly or irreversibly move from the bloodstream into the interstitial
and intracellular fluid.
Metabolism: bio-transformed via hepatic metabolism or by other tissues.
Elimination: lastly, the drug & its metabolites are eliminated from the body
The route of administration with the highest bio-availability is - answer-Intravenous;
putting entire dose into a patient's vein and bypassing absorption. Intravenous route
avoids first-pass metabolism in the liver.
rectal administration disadvantages - answer-variable and erratic absorption
Steady state (SS) - answer-is usually reached within 4-5 half-lives of a drug
The half-life of a drug is defined as - answer-how long it takes for half the drug to be
excreted from the body
,Half-life of a drug - answer-Determines how frequently the drug must be administered
Predicts how long toxic effects can last
Half-life is constant with first-order pharmacokinetics of a drug
Zero-order (nonlinear) pharmacokinetics means a drug is metabolized at a constant
rate per unit time.
CYP3A4 substrate drugs - answer-May have enhanced activity if any CYP3A4 inducer
drugs are used along with it.
Drug development steps (according to the FDA) - answer-Discovery: laboratory research
to develop the new drug
Pre-clinical research with animal testing for safety (Phase I)
Clinical research on human subjects for medication safety (Phase II)
Clinical research in humans comparing the new drug to accepted medications or
placebo depending on the study (Phase III)
FDA review of the results to determine approval
Post-marketing study to identify adverse effects not found in earlier clinical studies
(Phase IV)
Medication safety organizations - answer-The Institute for Safe Medication Practices
(ISMP)
, The Institute of Medicine (IOM)
The Joint Commission
The National Coordinating Council for Medication Error Reporting and Prevention
(NCCMERP)
Food and Drug Administration (FDA) Safe Use Initiative
Adverse Drug Reactions (ADRs) - answer-Two basic type of ADRs: pharmacological and
idiosyncratic.
85% to 90% of ADRs are pharmacological.
Adverse drug reactions are usually preventable, frequently occur in a hospital or nursing
home setting, and include medication errors, adverse drug effects, allergic and
idiosyncratic type reactions.
ADRs are not commonly reported; the FDA does not mandate that ADRs be reported.
Polypharmacy involves using multiple healthcare providers for care, using multiple
medications, and using several pharmacies for prescription filling.
Cardiovascular-Angiotensin converting enzyme inhibitors (ACEIs): - answer-Lisinopril,
captopril, enalapril, ramipril, benazepril, fosinopril;
*ACEIs reduce blood pressure by suppressing the release of angiotensin-converting
enzyme.
*Important side effects of ACE inhibitors include cough and angioedema; discontinue
the ACEI if angioedema occurs.
