Antivirals Flashcards
What are the three main types of antiviral drugs?
Nucleoside analogs, protease inhibitors, and release inhibitors.
True or False: Nucleoside analogs mimic the building blocks of viral DNA or RNA.
True.
Fill in the blank: Protease inhibitors block the action of ______, an enzyme crucial for viral replication.
protease.
What is the primary action of release inhibitors?
They prevent the release of new viral particles from infected cells.
Which type of antiviral drug is known for interfering with the viral replication process by mimicking nucleotides?
Nucleoside analogs.
Multiple choice: Which of the following is NOT a type of antiviral drug? A) Nucleoside analogs B) Protease inhibitors C) Antibiotics D) Release inhibitors
C) Antibiotics.
What is a common adverse effect associated with nucleoside analogs?
Bone marrow suppression.
True or False: Protease inhibitors can lead to metabolic side effects such as insulin resistance.
True.
Short answer: Name one example of a nucleoside analog.
Acyclovir.
Fill in the blank: Release inhibitors are primarily used to treat ______ infections.
influenza.
What is the mechanism of action for protease inhibitors?
They inhibit the protease enzyme, preventing viral protein maturation.
Multiple choice: Which of the following is a potential adverse effect of release inhibitors? A) Nausea B) Liver toxicity C) Rash D) All of the above
D) All of the above.
True or False: Nucleoside analogs are only effective against RNA viruses.
False.
Short answer: What is a key benefit of using protease inhibitors in antiviral therapy?
They can effectively reduce viral load.
Fill in the blank: The antiviral drug ______ is a well-known protease inhibitor used in the treatment of HIV.
Ritonavir.
What is the main goal of antiviral therapy?
To reduce the severity and duration of viral infections.
Multiple choice: Which class of antiviral drugs includes Oseltamivir? A) Nucleoside analogs B) Protease inhibitors C) Release inhibitors D) None of the above
C) Release inhibitors.
True or False: Adverse effects are not a concern with antiviral medications.
False.
Short answer: In addition to treating viral infections, what is another use of antiviral drugs?
Preventing viral infections in high-risk populations.
Fill in the blank: The primary action of nucleoside analogs is to ______ viral DNA or RNA synthesis.
inhibit.
What is a common viral infection treated with release inhibitors?
Influenza.
True or False: All antiviral drugs work by the same mechanism.
False.
Short answer: Name a side effect commonly associated with protease inhibitors.
Diabetes or hyperlipidemia.
Multiple choice: Which of the following best describes the role of nucleoside analogs? A) They enhance viral replication B) They inhibit protein synthesis C) They mimic nucleotides D) They promote viral release
C) They mimic nucleotides.
