What is the DAA for HCV?
In 2011, new medications named direct acting antivirals (DAA) were developed, which represents a major advancement in the treatment of HCV that achieved a virological response exceeding 90% in most genotypes. There is a very rapid progress in the development of DAAs that limits the ability to overwhelm the pharmacological details of each DAA. This review is a trial to give an overview of the pharmacology of most DAAs.
What is the direct acting antiviral therapy?
The direct acting antiviral therapy was started when the first-wave, first-generation HCV NS3-4A protease inhibitors boceprevir and telaprevir were approved in combination with PegIFN-alpha and ribavirin for the treatment of chronic HCV genotype 1 infection in 2011.[7] However, these drugs have been reported to have several drug-drug interactions, and are largely replaced with newer DAA including Simeprevir, Paritaprevir, Daclatasvir, Ledipasvir, Ombitasvir, Sofosbuvir and Dasabuvir. Table 3summarizes the pharmacokinetics of all approved DAA with special reference to the sites of drug-drug interaction. Clinical pharmacology of the newer DAA will be discussed in the next section.
What is a DAA?
Chronic hepatitis C virus (HCV) infection is a leading cause of chronic liver disease. The introduction of direct acting antiviral agents (DAAs) for its treatment represents a major advance in terms of sustained virologic response (SVR) rates and adverse effect profiles. Mechanistically, DAAs inhibit specific HCV non-structural proteins (NS) that are vital for its replication. Boceprevir, telaprevir, simeprevir, asunaprevir, grazoprevir and paritaprevir are NS3/4A inhibitors. Ombitasvir, ledipasvir, daclatasvir, elbasvir and velpatasvir are NS5A inhibitors. Sofosbuvir and dasabuvir are NS5B inhibitors. Currently, a combination of two or more DAAs is the corner stone for the treatment of HCV infection. However, the success of DAA therapy is facing several challenges, including the potential of drug-drug interactions and resistant variance. Moreover, the shortage of relevant clinical pharmacological data and drug interaction regarding DAA is a clinical concern. The present review discusses the clinical pharmacology of DAAs with special emphasis on drug-drug interaction.
How many people are infected with hepatitis C?
Globally, the chronic hepatitis C virus (HCV) is a leading cause of liver diseases such as liver cirrhosis and hepatocellular carcinoma. It affects approximately 180 million people worldwide; about 3% of the world population.[1] Three to four million persons are newly infected each year, with the predominant prevalence being infection with genotype 1, followed by genotypes 2 and 3. The other genotypes, 4, 5, and 6, have specific geographical distribution. The infection with HCV occurs as the result of percutaneous transmission via infectious blood (blood-to-blood). Less than 20% of those acutely infected clear the virus; the rest (70-80%) become chronically infected for decades, a significant fraction of whom die of HCV-related illnesses. [2]

What is hepatitis?
Hepatitis means inflammation of the liver. The liver is a vital organ that processes nutrients, filters the blood, and fights infections. When the liver is inflamed or damaged, its function can be affected. Heavy alcohol use, toxins, some medications, and certain medical conditions can cause hepatitis.
How does hepatitis C spread?
The hepatitis C virus is usually spread when someone comes into contact with blood from an infected person. This can happen through: ► Sharing drug-injection equipment. Today, most people become infected with hepatitis C by sharing needles, syringes, or any other equipment used to prepare and inject drugs. ► Birth.
What happens if you get hepatitis C?

What is the role of post cure care for hepatitis C?
Equally important aspects of postcure care are the prevention of liver disease progression and the management of complications in patients who have significant fibrosis at the time of achieving cure. Patients with advanced fibrosis need to remain under surveillance for liver complications, including hepatocellular carcinoma. All patients are potentially at risk for liver disease progression if other factors causing liver injury are present, such as harmful levels of alcohol use or risk factors for fatty liver including obesity, diabetes, and other metabolic comorbidities. Fatty liver is a particular threat to the long-term well-being of patients after HCV cure due to the high prevalence of its risk factors in this population. Strong counseling messages and ongoing monitoring are key.
What is the goal of HCV management?
The goals are 2-fold: to prevent reinfection and to prevent and treat complications of liver disease. Critical to appropriate triage of patients is accurate staging of liver fibrosis prior to cure. Patients with cirrhosis may develop HCC and other liver-related complications postcure, although the rates are significantly reduced by clearance of HCV. Specialists play a key role in educating nonspecialists regarding appropriate follow-up postcure and in caring for patients with advanced fibrosis and liver-related complications.
Why is it important to keep cured patients under the care of a specialist?
The rationale for keeping cured patients under the care of a specialist is to prevent and manage the complications of liver disease that can occur in spite of cure. The patients at highest risk for liver-related complications are those with cirrhosis at the time of cure. Longitudinal studies of DAA-treated patients with cirrhosis show a significant reduction in the risk of liver-related mortality for decompensation and HCC,27,28but risk persists. Patients with decompensated cirrhosis are at a higher risk of future liver complications than those with compensated cirrhosis. For patients with decompensated cirrhosis who achieve cure, approximately 75% will experience an improvement in MELD and Child-Pugh scores, but only 25% will improve to compensated cirrhosis.29Thus, most patients with decompensated cirrhosis remain at risk for liver complications and need close monitoring. Consideration of liver transplantation in appropriate patients is critical.
Is alcohol safe for HCV?
The achievement of HCV cure substantially reduces the risk of liver disease progression, but some patients remain at risk. Moreover, liver injury can occur from other causes before and after cure, specifically related to alcohol use or superimposed metabolic fatty liver. Thus, it is important to provide counseling messages to patients for lifelong liver health.16While safe levels of alcohol intake for otherwise healthy men and women are fewer than 4 and 2 drinks per day, respectively, these levels were defined in persons without known preexisting liver disease.17Thus, for patients with HCV infection who have underlying fibrosis, these levels cannot be considered safe, and abstinence is recommended.4For patients with no or minimal fibrosis, counseling messages should stress safe levels of alcohol use (≤2 drinks per day for men and ≤1 drink per day for women18), although a recent study suggests that even lower limits should be adopted.19Marijuana may also have profibrogenic potential in patients with fibrosis, so daily use is not recommended.20Fatty liver from metabolic causes (obesity, diabetes) is a major concern given the epidemic of these comorbidities in the population. Aiming for the ideal body weight and for control of metabolic cofactors is very important for maintenance of liver health after cure. Finally, avoidance of potentially hepatotoxic medications, herbal products, or over-the-counter medications should be mentioned to patients. Safe levels of acetaminophen are 2 g or less.
Can fibrosis progress after HCV cure?
Although the majority of patients, especially those without cirrhosis at baseline, will show evidence of fibrosis regression as time increases from HCV cure, some patients can progress. This may be related to concurrent alcohol use or the presence of nonalcoholic fatty liver disease. Alternatively, genetic or immunologic factors may contribute to the risk of liver complications after cure.26Given this possibility, counseling patients on measures for maintaining good liver health is important (Table). Additionally, periodic assessment of fibrosis severity using elastography may be beneficial. Post-SVR, the absolute value for liver stiffness is difficult to interpret and should not be relied upon to provide accurate staging information, although trends in liver stiffness values are helpful. For example, liver stiffness values that are stable or decreasing would be indicative of stable or reduced fibrosis, whereas an increase in liver stiffness values may reflect increased necroinflammation or fibrosis and promote further investigation into the cause. Importantly, even if post-SVR elastography measures show reversal of advanced fibrosis to levels indicative of F2 or less, this should not lead to a discontinuation of surveillance for HCC.4,5
