antivirals Flashcards
true or false: A virus cannot replicate on its own, must attach to a host cell and use host cells energy to synthesize protein, DNA and RNA
true
a well functioning immune system wiill eliminate or destroy a virus
competent immune system
Viruses controlled by antiviral therapy
Cytomegalovirus, hepatitis virus, herpes virus, human immunodeficiency virus (HIV), influenza, respiratory syncytial virus
what are some Characteristics of antiviral drugs
Can enter cells infected with virus
Interfere with viral nucleic acid synthesis/regulation
Some interfere with ability of virus to bind to cells
Some stimulate body’s immune system
used to treat infections caused by viruses other than HIV
Antiviral agents
treatment for recurrent chicken pox or shingles. Used within 24 hours of appearance, Used orally, topically or parenterally
Acyclovir
used to treat infections caused by HIV and the virus that causes aids
Antiretroviral agents
true or false: many drugs interact with antiviral agents
true
enzyme-linked immunosorbent assay: detects HIV exposure based on presence of antibodies
ELISA
uses RNA as its genetic material, injects into host cell changing the genome of that cell
Retrovirus
block synthesis of new viral DNA
Reverse transcriptase inhibitors
prevent breakdown of protein chains to prevent viral replication
Protease Inhibitors
prevents attachment to host cell
Fusion Inhibitors
