What are the three first line drugs for the treatment of chronic hepatitis B?

Currently, pegylated interferon alfa (PEG-IFN-a), entecavir (ETV), and tenofovir disoproxil fumarate (TDF) are the first-line agents in the treatment of hepatitis B disease.

Is entecavir a nucleoside analogue?

Entecavir, a new guanosine nucleoside analogue with specific activity against HBV DNA polymerase, represents a third agent within the nucleoside/nucleotide HBV polymerase inhibitor class.

What is the drug of choice for hepatitis B?

Treatment for chronic hepatitis B may include: Antiviral medications. Several antiviral medications — including entecavir (Baraclude), tenofovir (Viread), lamivudine (Epivir), adefovir (Hepsera) and telbivudine (Tyzeka) — can help fight the virus and slow its ability to damage your liver.

The best way to prevent hepatitis B is with vaccination. Other ways to reduce your risk of getting hepatitis B, hepatitis C, and HIV: Do not inject drugs. If you do inject drugs, stop and get into a treatment program.

Is HBV treatment lifelong?

Available therapies for HBV require lifelong treatment and surveillance, as reactivation frequently occurs following medication cessation and the occurrence of HCC is decreased but not eliminated, even after years of successful viral suppression.

How long should I take tenofovir for hepatitis B?

Background: Long-term tenofovir disoproxil fumarate (TDF) treatment for chronic hepatitis B (CHB) is associated with sustained viral suppression and regression of fibrosis and cirrhosis at year 5 (240 weeks) and no TDF resistance through 6 years (288 weeks).

Which drug is not a nucleoside analog?

The widely used vasodilator and antiarrhythmic agents, hydralazine [38], and procainamide [39], have been demonstrated to be non-nucleoside analog DNMT inhibitors. These drugs exhibit less cytotoxicity because they do not require incorporation into DNA [18].

Which antiviral drug is thymidine analog?

Trifluridine☆ A thymidine analog that inhibits DNA polymerase activity, trifluridine is an antiviral drug used primarily as a treatment of Herpes Simplex Virus (HSV-1 and HSV-2) and vaccinia virus [Drug Facts and Comparison (2001)].

What is the first treatment for hepatitis?

If your liver is working fairly well, the first treatment offered is usually a medicine called peginterferon alfa 2-a. This stimulates the immune system to attack the hepatitis B virus and regain control over it. It’s usually given by injection once a week for 48 weeks.

Is hepatitis B treatable by medicines?

Hepatitis B medications can help keep the virus under control and stop it damaging your liver, although they will not necessarily cure the infection and some people need lifelong treatment. The main medicines for chronic hepatitis B include peginterferon alfa 2-a and antiviral medicines.

What is the life expectancy of someone with hepatitis B?

3). Among those aged 80 to 84 years, HCC carries the highest risk among both men and women. Since e antigen conveys a 6.27 RR for HCC mortality, e-positive adults are always at higher risk….

Which drugs are nucleoside analogs?

Actually, nucleoside analogues are a large class of agents that include drugs for cancer (cytarabine, gemcitabine, mercaptopurine, azacytidine, cladribine, decitabine, fluorouracil, floxuridine, fludarabine, nelarabine), and rheumatologic diseases (azathioprine, allopurinol) and even bacterial infections (trimethoprim) …

Is acyclovir a nucleoside analog?

Acyclovir (9-[2-hydroxymethyl]guanine) is a nucleoside analog that selectively inhibits the replication of herpes simplex virus types 1 and 2 (HSV-1, HSV-2) and varicella-zoster virus (VZV).
