,Define: Over-the-counter drug - Answer: One that may be purchased without prescription from a

, Describe the sequence of events that a drug undergoes from administration to excretion - Answer:
Drug is absorbed (or placed directly) into the bloodstream, the drug may bind with plasma in the blood
or may exist in free state, circulating blood distributes drug to capillary level where it leaves circulation
and enters interstitial fluid. it bathes the cell and allows drug to bind to cell surface receptors or enter
the cell. It then exits the cell and moves back into interstitial fluid, reenters circulation, and is
transported to liver for metabolism. The metabolite is then transported to kidneys for excretion.
List 11 possible routes for administering a drug to a patient. - Answer: Oral, subcutaneous,
intramuscular, intravenous, intraperitoneal, intraarterial, intracardiac, intramedullary, inhalation,
topical, intradermal
List some of the factors that influence drug absorption - Answer: Method of absorption, pH of the drug
and ionization status, absorptive surface area, blood supply to area, solubility of drug, dosage form,
status of GI tract, and interactions with other drugs
Most biotransformation occurs in the_____ - Answer: Liver
Most drug excretion occurs via the ______ - Answer: Kidneys
Drugs usually produce their effects by combining with specific cellular_____ - Answer: Receptors
The drug name chosen by the manufacturer and is exclusive property of that company is called -
Answer: Trade/Proprietary Name
What are the 6 items that must be included on drug label? - Answer: names (generic and trade)
