Definition
antiviral- uncoating inhibitors, inhibits release of new virons. oral, only RNA viruses, influenza A.
Term
Rimantadine (flumadine)
Definition
antiviral- uncoating inhibitors, inhibits release of new virons. oral, only RNA viruses, influenza A.
Term
Ribavirin
Definition
Antiviral- synthetic guanosine analog. Inhibition of viral mRNA synthesis. effective against broad RNA & DNA. TX for severe Respiratory syncytial virus (RSV) in infants and young children; acute hep A, influenza A&B, lassa hemorrhagic fever
Term
INF a2b (intron A)
Definition
antiviral- hepatitis virus, appears to induce host cell enzymes that inhibit viral RNA translation & ultimately lead to degradation of viral mRNA & tRNA. AE fever, lethargy, bone marrow depression, cardiovascular problems.
Term
Rebetron (INFa2b+ ribavirin)
Definition
antiviral- TX of chronic Hep C
Term
Acyclovir (zovirax)
Definition
antiviral- herpes. guanosine analog. selectively inhibits viral DNA polymerase & is incorporated into viral DNA where it acts as a chain terminator. distributes everywhere. TX for genital/oral herpes. DOC herpes simplex encephalitis. Not CMV
Term
Ganciclovir
Definition
antiviral- herpes. analog, inhibits viral DNA polymerase. TX for cytomegalovirus (CMV)
Term
Zostavax
Definition
antiviral- herpes. shingles vaccine
Term
Foscarnet
Definition
antiviral- herpes. IV, broad antiviral activity; reversibly inhibits DNA//RNA polymerases. TX CMV, HSV, HZV
Term
Famciclovir (famvir)
Definition
antivirals- herpes. inhibit DNA polymerase. TX HSV 1, HSV 2, HZV
Term
Enfuvirtide (T20, ENF, Fuzeon)
Definition
antiviral-HIV, viral fusion inhibitor, viral GP41- entry inhibitor. AE= rxn at injection site, eosiniphilia, systemic hypersensitivity rxn, ↑ bacterial pneumonia
Term
Raltegravir (isentress)
Definition
antiviral- HIV, integrase inhibitor, inhibits integration of viral strand DNA into host DNA. AE= nausea, HA, Diarrhea
Term
Zidovudine (azt)
Definition
antiviral- HIV, NRTI. azt incorporated into the growing viral DNA- causes chain termination. well absorbed PO, penetrate CNS. decreases transmission of HIV to fetus
Term
BMS, HA, NV, anorexia inhibition mitochondria DNA polumerase, peripheral neuropathy, pancreatitis, lipoatrophy, liver toxicity

Definition
antiviral-HIV, protease inhibitors. prevents post-translational processing of viral polyproteins,well tolerated. oral, p450 metabolism. given in combination
Term
Indinavir (crixivan)
Definition
antiviral- HIV, protease inhibitors
