Final answer:
A drug which ends in the suffix, -pril, is considered a(n): ACE inhibitor (Option B). This is used for blood pressure management and is distinct from antiviral drugs which are designed to treat specific viral infections.
Step-by-step explanation:
A drug with the suffix -pril is considered an ACE inhibitor, which is used primarily in the treatment of hypertension.
These medications work by blocking the angiotensin-converting enzyme (ACE), which is responsible for the conversion of angiotensin I to the potent vasoconstrictor angiotensin II.
This action results in vasodilation and a reduction in blood pressure. ACE inhibitors are different from antiviral drugs, which target viral infections by inhibiting their development rather than killing the virus outright.
Antiviral drugs, such as Tamiflu, Relenza, AZT, and others, are designed to treat specific viral infections by interfering with various stages of viral replication.
Hence, the correct answer is ACE inhibitor (Option B).
