Answer to Question 1

ANS: A
Azelastine blocks the release of histamine and is indicated for allergic or vasomotor rhinitis. It is administered by nasal spray and is a second-generation medication.
Chlorpheniramine is a first-generation agent and is administered by mouth.
Desloratadine is a second-generation medication administered only by mouth.
Phenindamine is also a first-generation medication taken by mouth.

Answer to Question 2

ANS: A
Antihistamines are of practically no value against the common cold. They neither prevent colds nor shorten their duration.
Antihistamines are useful for treating allergic disorders, motion sickness, itching, and insomnia.
Antihistamines show a moderate reduction in rhinorrhea.
