Prucalopride is a dihydrobenzofurancarboxamide derivative from the benzofurane family that selectively stimulates 5-HT4 receptors and thus, it presents enterokinetic properties. The high selectivity of prucalopride allowed further development as it prevented the cardiac adverse reactions observed due to non-target effects of precedent therapies. Prucalopride was developed by Shire Development LLC and approved for use in Europe in 2009, in Canada on December 7, 2011 and by the FDA on December 17, 2018.
Velpatasvir is a Direct-Acting Antiviral (DAA) medication used as part of combination therapy to treat chronic Hepatitis C, an infectious liver disease caused by infection with Hepatitis C Virus (HCV). HCV is a single-stranded RNA virus that is categorized into nine distinct genotypes, with genotype 1 being the most common in the United States, and affecting 72% of all chronic HCV patients . Velpatasvir acts as a defective substrate for NS5A (Non-Structural Protein 5A), a non-enzymatic viral protein that plays a key role in Hepatitis C Virus replication, assembly, and modulation of host immune responses . Treatment options for chronic Hepatitis C have advanced significantly since 2011, with the development of Direct Acting Antivirals (DAAs) such as velpatasvir. Notably, velpatasvir has a significantly higher barrier to resistance than the first generation NS5A inhibitors, such as and , making it a highly potent and reliable alternative for treatment of chronic Hepatitis C . In a joint recommendation published in 2016, the American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA) recommend Velpatasvir as first line therapy in combination with sofosbuvir for all six genotypes of Hepatitis C . Velpatasvir is currently only available within a fixed dose combination product as Epclusa with , another direct acting antiviral. Goals of therapy for Epclusa include the intent to cure, or achieve a sustained virologic response (SVR), after 12 weeks of daily therapy. SVR and eradication of HCV infection is associated with significant long-term health benefits including reduced liver-related damage, improved quality of life, reduced incidence of Hepatocellular Carcinoma, and reduced all-cause mortality and risk of requiring a liver transplant . Since June 2016, Velpatasvir has been available as a fixed dose combination product with , as the commercially available product Epclusa. Epclusa is the first combination HCV product indicated for the treatment of all genotypes of Hepatitis C with or without cirrhosis. It is also currently the most potent HCV antiviral medication on the market with a sustained virologic response (SVR) after 12 weeks of therapy of 93-99% depending on genotype and level of cirrhosis and a high barrier to resistance . Both Canadian and American guidelines list Epclusa as a first line recommendation for all genotypes of HCV [L852, A19626].
