EXAM QUESTIONS
Q1. Flagyl, ER
CORRECT ANSWER
Metronidazole
RATIONALE
Flagyl is a brand name for the medication Metronidazole, which is an antibiotic used
to treat various bacterial infections. The "ER" in Flagyl ER stands for "extended-
, release," which means the medication is formulated to release its active ingredient,
Metronidazole, more slowly over time to provide sustained therapeutic effects.
Q2. Diflucan
CORRECT ANSWER
Fluconazole
RATIONALE
"Diflucan" is a brand name of the antifungal medication Fluconazole, a common
generic term for this medication. This is because the term "Diflucan" is a proprietary
name assigned to the drug by its manufacturer, GlaxoSmithKline, which is then
replaced by its generic name Fluconazole when referring to it by its chemical name.
Q3. Nizoral
CORRECT ANSWER
Ketoconazole
RATIONALE
Nizoral is a brand name for Ketoconazole, a type of antifungal medication. The
correct answer is Ketoconazole because it is the generic or chemical name of the
, active ingredient in Nizoral, allowing for a more precise and universal identification
of the substance.
Q4. Mycostatin, Nystop
CORRECT ANSWER
Nystatin
RATIONALE
"Nystatin" is the correct answer because it is the generic name of the antifungal
medication, whereas "Mycostatin" and "Nystop" are brand names. This distinction

name assigned by a regulatory agency, and its brand name, which is a proprietary
name chosen by the manufacturer.

CORRECT ANSWER
Terbinafine
RATIONALE
Terbinafine is the correct answer because it is the active ingredient in the
medication Lamisil, which is used to treat fungal infections such as athlete's foot
and toenail fungus. The relationship between the two is a classic example of a
, generic name and its corresponding brand name, where terbinafine is the generic
name and Lamisil is the brand name.
Q6. Zovirax
CORRECT ANSWER
Acyclovir
RATIONALE
Zovirax is an antiviral medication brand name, and Acyclovir is the generic name of
the active ingredient contained within the brand name. This means that Acyclovir is
the chemical name for the medication, whereas Zovirax is the specific brand under
which it is marketed.
Q7. Valtrex
CORRECT ANSWER
Valacyclovir
RATIONALE
