Cards

Term
Blocks Viral penetration/uncoating (M2 protein). Prophylaxis and treatment for influenza A

Also causes a release of dopamine from intact nerve terminals (for Parkinsons)
Definition
Amantadine

Toxicity: ataxia, dizziness, slurred speech
Term
Inhibits influenza neuraminidase, decreasing the release of progeny virus
Definition
Zanamivir
Oseltamivir
Term
Inhibits synthesis of guanine nucleotides by competitively inhibiting IMP dehydrogenase

Used for RSV and chronic hepatitis C
Definition
Ribavirin

Toxicity:
Hemolytic anemia
Teratogenic
Term
Monophosphorylated by viral thymidine kinase. Inhibits viral DNA polymerase by chain termination

Used for HSV, VZV, EBV
Definition
Acyclovir

Mech of resistance: lack of thymidine kinase
Term
Similar to acyclovir, except guanine analog formed by CMV viral kinase

Used to stop DNA polymerase
Definition
Ganciclovir

Toxicity: leukopenia, neutropenia, thrombocytopenia, renal toxicity
Term
Viral DNA polyermase inhibitor that does not require viral kinase activation

Used when ganciclovir fails
Definition
Foscarnet

Does not cause bone marrow suppression
Term
Glycoproteins from human leukocytes that block various stages of viral RNA and DNA synthesis

Used for Chronic hepatitis B and C, kaposi sarcoma
Definition
Interferon alpha
Term
Glycoproteins from human leukocytes that block various stages of viral RNA and DNA synthesis

Used for Multiple sclerosis
Definition
Interferon beta
Term
Glycoproteins from human leukocytes that block various stages of viral RNA and DNA synthesis

Used for NADPH oxidase deficiency
Definition
Interferon gamma
