CORRECT ANSWERS (ALREADY GRADED A+) (2024 UPDATE)
100%
Pharmaceutic Phase - ANSWER- drug becomes a solution so that it can cross the biological
membrane.
No Pharmaceutic Phase When - ANSWER- it is administered by SubQ, IV, and IM routes
Disintegration - ANSWER- breakdown of a tablet to smaller particles.
Dissolution - ANSWER- dissolve small particles in GI fluid before absorption; absorption
occurs slower in abdomen.
Rate Limiting or Dissolution - ANSWER- length of time it takes a drug to become available
for body to absorb it.
Excipients - ANSWER- are fillers and inert substances that are used to allow the drug to take
on particular size, shape, and to enhance drug dissolution.
Enteric Coated Tablets - ANSWER- should never be crushed or taken after the consumption of
fatty foods.
Pharmacokinetic Phase - ANSWER- process of drug movement to achieve drug action;
includes four phases.
, 1. Absorption - ANSWER- is the movement of drug particles from the GI to body fluids by
passive, active, and pinocytosis
Passive Absorption - ANSWER- mostly by diffusion (high concentration to low concentration)
Active Absorption - ANSWER- requires a carrier such as an enzyme or protein; it requires
energy
Pinocytosis - ANSWER- process by which cells carry a drug across a membrane by engulfing
the drug particles
Affects Drug Absorption - ANSWER- 1. blood flow
2. pain
3. stress
4. hunger/ fasting
5. food
6. pH
First Pass Effect - ANSWER- process in which drugs passes the liver first
Bioavailability - ANSWER- it is the percentage of the administered drug dose that reaches the
systemic circulation
Factors that Alter Bioavailability - ANSWER- 1. drug form
2. route of administration
