Anti Virals Flashcards
Tenofovir
Treats: HIV and HBV
MoA: Nuleoside Reverse Transcriptase Inhibitor; requires tri-phosphorylation; Bind RT and incorporates and causes chain termination
Adverse: Lactic Acidosis
Notes: Prodrug available that activates in lymphoid tissues to lower systemic toxicity.
Emtricitabine
Treats: HIV and HBV
MoA: Nuleoside Reverse Transcriptase Inhibitor; requires tri-phosphorylation; Bind RT and incorporates and causes chain termination
Adverse: Lactic Acidosis
Efavirenz
Treats: HIV
MoA: Non-nucleoside reverse transcriptase inhibitor; binds RT and induces lower activity
Adverse: Hepatoxicity, skin rashes
Darunavir
Treats: HIV
MoA: HIV protease inhibitor via active site binding; prevents processing of polypeptides into mature proteins; produces non-infectious virions
Adverse: Dyslipidemia, insulin resistance, GI effects
Notes: Substrate for Cytochrome P450
Ritonavir
Treats: HIV
MoA: HIV protease inhibitor via active site binding; prevents processing of polypeptides into mature proteins; produces non-infectious virions
Adverse: Dyslipidemia, insulin resistance, GI effects
Notes: Strong inhibiting substrate for Cytochrome P450
Dolutegravir
Treats: HIV
MoA: Inhibits HIV integrase
Enfuvirtide
Treats: HIV
MoA: Prevents fusion of HIV with cell membranes
Maraviroc
Treats: HIV
MoA: Binds CCR5; blocks interaction with T cells and monocytes
Adverse: Hepatoxicity and systemic allergic reaction
Oseltamivir
Treats: Influenza
MoA: Neurominidase Inhibitor; blocks release of influenza virus from infected cells
Paritaprevir
Treats: Hep C
MoA: Inhibits Hep C Protease; prevents processing of HCV polyprotein
Ledipasvir
Treats: Hep C
MoA: Inhibits Hep C phosphoprotein required for viral RNA sunth and assembly
Ombitasvir
Treats: Hep C
MoA: Inhibits Hep C phosphoprotein required for viral RNA sunth and assembly
Sofosbuvir
Treats: Hep C
MoA: Inhibits Hep C RNA pol
Acyclovir
Treats: Herpes (HSV VZV)
MoA: Blocks viral DNA synth; Inhibits viral pol and incorporates into DNA causing chain termination
Notes: Requires activation via viral Thymidine Kinase
Ganciclovir
Treats: Herpes (CMV)
MoA: Blocks viral DNA synth; Inhibits viral pol; NO CHAIN TERMINATION
Adverse: Bone marrow depression
Notes: Requires activation via viral Thymidine Kinase; less selective than acyclovir therefore more toxic
