1. Pharmacokinetics - ANSWER The disposition of the drug in the body
over time
2. Drugs are more stable when in solution than when in dry form - ANSWER
false
3. Define capsules
- ANSWER solid dosage form enclosing drug within small container
4. Types of capsules
- ANSWER -hard gelatin
-soft gelatin
5. (ODT) Orally Disintegrating Tablet - ANSWER compressed tablets,
intended for oral administration, NO sugar coating
6. Eutectic pictures - ANSWER combination of two substances of low
intermolecular attractive forces with low melting point, resulting in a
liquefied product
,7. The majority of drugs on the market are small organic molecule drugs
made by chemical synthesis - ANSWER TRUE
8. Dosage forms - ANSWER drug products in the form in which they are
marketed for use, with a specific picture of active ingredients along with
excipients (non active), in a particular configuration and apportioned into a
particular dose, for a variety of purposes including ensuring accurate dose,
protecting drug integrity, and preventing contamination
9. Oral drugs with high membrane permeability - ANSWER drug
absorption from the intestinal lumen may be determined by the dissolution
rate of drugs from oral dosage forms
10. Based on properties of solutions, concentration of solute is a colligative
property - ANSWER FALSE, colligative properties are A property that
depends only upon the number of solute particles, and not upon their
identity

12. Atropine sulfate is more water soluble than atropine - ANSWER TRUE
13. Crystal polymorphs of a drug can have different aqueous solubility due to
different chemical properties - ANSWER FALSE
, 14. The stronger a weak acid, the smaller its Ka value - ANSWER FALSE,
the smaller the pKa value
15. A weak electrolyte will have incomplete ionization in an aqueous solution -
ANSWER TRUE
16. The capacity of buffer is determined by total buffer concentration only -
ANSWER FALSE
17. Acid base reaction: OH+NH4-->H2O+NH3, H2O can be considered a
conjugate acid - ANSWER TRUE
18. Osmolarity of drug is determined by chemical and physical natures of drug
molecules in the solutions - ANSWER FALSE
19. IV infusion of a large volume of a hypertonic solution will likely increase PT
blood pressure - ANSWER TRUE
20. IF solution's osmolarity=physiological body fluids or tissues it can be
considered isotonic - ANSWER FALSE
21. Sterility/pyrogenicty are two terms that describe essential the same
concept that is the absence of viable microbial contamination - ANSWER
FALSE
22. No coloring agents are allowed in parenteral formulations - ANSWER
TRUE
