Narlaprevir: A Case Study

Decent Essays
Ki: 6 nM

Narlaprevir is a HCV NS3 protease inhibitor.

NS3 protease is essential for viral replication representing an important target for antiviral therapy. Since identification of NS3 protease, this chymotrypsin-like serine protease has been found to be an attractive target for HCV antiviral therapeutics.

In vitro: Narlaprevir was identified to be a novel ketoamide protease inhibitor which formed a reversible covalent bond with the active-site serine. Narlaprevir could inhibit replicon RNA at a EC90 of 40 nM. Morevoer, in biochemical assays, narlaprevir was active against proteases of genotypes 1 to 3. In addition, cross-resistance studies showed the majority of mutations for resistance to boceprevir and telaprevir caused similar fold

    By this point, depending on the severity of the patient’s HCV, patients usually take a combination of medications such as Sovaldi, Olysio, Incivek, Victreli, and Viekira Pak to manage their HCV, but never completely treat it (Mayo Clinic). In addition however, many of these patients were also infected with Human Immunodeficiency Virus (HIV). During the 1900s, HIV was one of the most significant viral infections in patients, and HCV was underestimated in significance. Once HIV was controlled through highly active antiretroviral treatment (HAART), some of these patients were found to be co infected with HCV, increasing the awareness of HCV.

    Prilosec Case Study

    Prilosec (omeprazole), a proton pump inhibitor that reduces the amount of acid produced in the stomach in conditions caused by excess stomach acid. Prilosec suppresses gastric acid secretion by target inhibition of the H+/K+ ATPase enzyme system at the secretory surface of the gastric parietal cell. This enzyme system is considered as the acid (proton) pump within the gastric mucosa, Prilosec has been characterized as a gastric acid-pump inhibitor, because it blocks the final step of acid production. This result is dose-related and leads to inhibition of both basal and gastric acid secretion regardless of stimuli. Prilosec was prescribed for L.G. to treat his symptoms of gastroesophageal reflux disease (GERD).…

    It is estimated that there are currently 43 million Americans at risk of anaphylaxis, a life-threatening allergic reaction (“Mylan’s Commitment,” 2016). The majority of these people are in constant possession of an EpiPen, an auto-injector containing epinephrine used to reverse anaphylaxis (“Anaphylaxis,” 2016). However, in recent years the price of the EpiPen has increased substantially; a two-pack currently costs $609 (Pollack, 2016). Because Mylan commands around 85 percent of the epinephrine auto-injector market, almost all of those at risk have been affected (Herrick, 2016: 2). Concerns about drug price increases, like the EpiPen’s, have caused confusion in many people.…
