BIOPHARMACEUTICS &
PHARMACOKINETICS EXAM 2025/2026
QUESTIONS AND ANSWERS 100% PASS
Which dosage form is generally absorbed fastest, and which is absorbed slowest? -
ANS Fastest: Solutions
Slowest: Enteric coated tablets
What are three factors that affect drug distribution throughout the body? - ANS 1) Cardiac
output
2) Regional bloodflow
3) Drug reservoirs
What are three primary means of drug elimination? - ANS 1) Kidneys
2) Intestines
3) Respiratory system
Define Lipophilicity - ANS A drug with good lipid solubility will be able to cross lipid-layered
membranes easier.

,What are at least four factors controlling the rate and extent of drug absorption? - ANS 1)
Surface area
2) Blood flow
3) Solubility of drug
4) pH
5) drug concentration
6) dosage form
What are the differences and similarities between drug absorption via passive diffusion and
drug absorption via active transport? - ANS Passive diffusion is the random movement of a
substance from a region of higher concentration to a region of lower concentration until
equilibrium is established at the membrane. The majority of drugs are transported by this
mechanism. "carriers" that form complexes with drug molecules on one surface of the
membrane, carry them through the membrane, and then let them go conduct active transport.
The ionic forms of most drugs do not readily enter cells and therefore require active transport.
Active transport is usually more rapid than passive diffusion.
The ________ and the _________ are two drug distribution barriers the body has that are
made of biologic membranes. - ANS Blood-brain barrier, placental barrier
________ is another name for metabolism. - ANS biotransformation
________ is the area of pharmacology that focuses on the method for achieving effective drug
administration. - ANS biopharmaceutics
________ includes the processes of how a drug is absorbed, distributed, metabolized, and
eliminated throughout the body. - ANS pharmacokinetics
The most common way drugs transverse cellular membranes is ________. - ANS passive
diffusion

, _______ can move a drug from an area of low concentration to an area of higher
concentration. - ANS active transport
Medications must go through disintegration and _______ in order to be absorbed across a cell
membrane. - ANS dissolution
lozenges or pastilles; topical oral antifungals - ANS Troches
Less expensive to manufacture than sugar coating - ANS Film-coated tablets
Subject to chemical degradation from the environment - ANS Compressed tablets
Hard or soft gelatin encloses the active ingredient - ANS Capsules
Mask taste and protect active ingredients from chemical oxidation - ANS Sugar-coated
tablets
Release medicinal agent on contact with mucosa and melting - ANS Compressed
suppositories
Release active ingredients into the small intestine - ANS Enteric-coated tablets
Injection under or through one or more layers of skin or mucous membrane - ANS Parenteral
dosage forms
What is the term for the substance into which a drug is compounded for initial delivery into the
body?
a) Drug dose
