Considering this, is antibacterial and antifungal the same?

Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi. Agents that kill microbes are microbicidal, while those that merely inhibit their growth are called biostatic.

do antivirals weaken immune system? The inhibitory effects of antivirals on immune cells may contribute to the immune deterioration observed in patients following prolonged use of the drugs.

Keeping this in view, what is the difference between antibacterial and antiviral?

Antivirals are drugs that can treat people who have already been infected by a virus. Antibiotics are medicines that interfere with the reproduction of bacteria and are, therefore, only useful for treating bacterial infections.

What are the three classes of antiviral drugs?

Pharmacologic drug classes include:

  • Nucleoside reverse transcriptase inhibitors (NRTIs)
  • Non-nucleoside reverse transcriptase inhibitors (NNRTIs)
  • Protease inhibitors (PIs)
  • Integrase inhibitors (INSTIs)
  • Fusion inhibitors (FIs)
  • Chemokine receptor antagonists (CCR5 antagonists)

Why is antiviral drug difficult?

Designing safe and effective antiviral drugs is difficult, because viruses use the host's cells to replicate. This makes it difficult to find targets for the drug that would interfere with the virus without also harming the host organism's cells.

Why do doctors prescribe antibiotics for viral infections?

Illnesses caused by viruses (especially in the nose and throat) are more common than illnesses caused by bacteria. Antibiotics are strong medicines that treat bacterial infections. Antibiotics won't treat viral infections because they can't kill viruses. You'll get better when the viral infection has run its course.

How do you kill a virus?

Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus. However, antiviral medications and vaccines are specific for viruses.
