Quiz 6 Flashcards
oseltamivir 1
Brand: Tamiflu
Class: Neuraminidase inhibitor
Indication: Influenza treatment and prophylaxis
oseltamivir 2
MOA: Inhibits neuraminidase, preventing viral release. Neuraminidase is an enzyme that clips the viral hemagluttin from the sialic acid on the cell, causing viral release from the cell.
BBW: N/A
SE: nausea & vomiting
elbasvir + grazoprevir 1
Brand: Zepatier
Class: NS5A inhibitor + protease inhibitor
Indication: Hepatitis C
elbasvir + grazoprevir 2
MOA: Elbasvir - binds to the N-terminus within Domain 1 of HCV nonstructural protein 5A (NS5A) and inhibits viral RNA replication and virion assembly. Grazoprevir - inhibiting the protease necessary for proteolytic cleavage of HCV encoded polyproteins used for viral replication
BBW: N/A
SE: HA, nausea, fatigue
sofosbuvir + velpatasvir 1
Brand: Epclusa
Class: NS5B RNA polymerase inhibitor + NS5A inhibitor
Indication: Hepatitis C.
sofosbuvir + velpatasvir 2
MOA: Velpatasvir inhibits the HCV NS5A protein necessary for viral replication. Sofosbuvir - prodrug converted to its pharmacologically active form (GS-461203), which inhibits NS5B RNA-dependent RNA polymerase, also essential for viral replication, and acts as a chain terminator.
BBW: N/A
SE: HA, nausea, fatigue
sofosbuvir + ledipasvir 1
Brand: Harvoni
Class: NS5B RNA polymerase inhibitor + NS5A inhibitor
Indication: Hepatitis C
sofosbuvir + ledipasvir 2
MOA: Ledipasvir inhibits the HCV NS5A protein necessary for viral replication; sofosbuvir is a prodrug converted to its pharmacologically active form (GS-461203), inhibits NS5B RNA-dependent RNA polymerase, also essential for viral replication, and acts as a chain terminator.
BBW: N/A
SE: HA, fatigue, asthenia
ombitasvir + paritaprevir + ritonavir + dasabuvir 1
Brand: Viekira Pak
Indication: Hepatitis C
Class: NS5A inhibitor + protease inhibitor + CYP3A4 inhibitor + NS5B RNA polymerase inhibitor
ombitasvir + paritaprevir + ritonavir + dasabuvir 2
MOA: Ombitasvir inhibits HCV NS5A, and interferes with viral RNA replication and virion assembly. Paritaprevir inhibits HCV NS3/4A protease and interferes with HCV coded polyprotein cleavage necessary for viral replication. Dasabuvir inhibits HCV RNA-dependent RNA polymerase (encoded by the NS5B gene) which is also necessary for viral replication. Ritonavir is a CYP3A inhibitor that increases concentrations of paritaprevir.
BBW: N/A
SE: Skin reactions, pruritis, nausea, insomnia, fatigue
peginterferon alfa-2a 1
Brand name: Pegasys
Class: Interferon
Indication: Hep B & C
peginterferon alfa-2a 2
MOA: Interferons interact with cells through high affinity cell surface receptors. Following activation, multiple effects can be detected including induction of gene transcription. Interferons inhibit cellular growth, alter the state of cellular differentiation, interfere with oncogene expression, alter cell surface antigen expression, increase phagocytic activity of macrophages, and augment cytotoxicity of lymphocytes for target cells.
BBW: Risk of serious disorders and ribavirin-associated effects; combination with ribavirin (may cause birth defects, death of fetus)
SE: alopecia, dermatitis, injection site inflammation/rxn, pruritus, rash, high TG, weight loss, abdominal pain, N/V/D, loss of appetite, arthralgia, myalgia, dizziness, HA, insomnia, anxiety, dyspnea, fatigue, fever, influenza-like illness, rigor
ribavirin 1
Brand name: Virazole
Class: Antihepaciviral, Nucleoside (Anti-HCV)
Indication: Chronic Hep C
ribavirin 2
MOA: Inhibits replication of RNA and DNA viruses; inhibits influenza virus RNA polymerase activity and inhibits the initiation and elongation of RNA fragments resulting in inhibition of viral protein synthesis
BBW: Should not be used alone for treatment of Hep C; Hemolytic anemia (which could lead to CV complications); Teratogenicity
SE: injection site rxn, weight loss, diarrhea, loss of appetite, N/V, neutropenia, asthenia, dizziness, HA, insomnia, fatigue, influenza-like illness
lidocaine 1
Lidoderm, generics
Class: Antiarrhythmic Agent, Class Ib; Local Anesthetic
Indication: Local and regional anesthesia by infiltration, nerve block, epidural, or spinal techniques; acute treatment of ventricular arrhythmias from myocardial infarction or cardiac manipulation (eg, cardiac surgery)
