A.  Powders
B.  Tablets
C.  Troches
D.  Capsules 

 Powders are drugs or drug extracts that are dried and ground into fine particles.

A.  Asthma
B.  Bradycardia
C.  Sore throat
D.  Toothache

5.  Among the factors that affect drug distribution, the factor that plays the biggest role in determining the concentration of a drug that penetrates the brain by overcoming the blood–brain barrier is:
A.  lipid solubility.
B.  blood circulation.
C.  plasma protein binding.
D.  GI absorption rate. 

 An additional lipid barrier, the blood–brain barrier, protects the brain by restricting the passage of electrolytes and other water-soluble substances. Since the brain is composed of a large amount of lipid (nerve membranes and myelin), lipid-soluble drugs pass readily into the brain. As a general rule, then, a drug must have a certain degree of lipid solubility if it is to penetrate this barrier and gain access to the brain.

A.  Elixir
B.  Tincture
C.  Syrup
D.  Fluid extract 

 Syrups are commonly used aqueous preparations. A syrup is a solution of water and sugar to which a drug is added.

7.  The processes of drug absorption, drug distribution, drug metabolism, and drug excretion are components of the study known as _____.
A.  synergism
B.  pharmacokinetics
