Entehep 1mg (Entecavir 1mg) tablets are nor curable, may it used to reduce the amount of HBV virus in the body Entehep 1mg (Entecavir 1mg) diminishing the capability of HBV for multiplication and infecting new liver cells Entehep 1mg (Entecavir 1mg) enhance the condition of liver Entehep 1mg (Entecavir 1mg) used to reduce the chance of getting liver cancer & liver failure due to hepatitis B infection in chronic.

Medical use /Indication of Entehep 1mg (Entecavir 1mg)

The major usage of Entehep 1mg (Entecavir 1mg) tablets are :
Entehep 1mg (Entecavir 1mg) tablets are involved in the treatment of chronic hepatitis B viral infection in adults and pediatric patients with the age of 2 years and older with the sign of active viral production, either constant eminence of serum aminotransferase or histological effective disease. Before initiating the therapy with Entehep 1mg (Entecavir 1mg) tablets, the crucial points should be considered; The evidence of Entehep 1mg (Entecavir 1mg) in adult patients based on the clinical trial data in nucleoside inhibitor therapy for new patients and patient opposed to lamivudine treatment with HBeAg positive and HBeAg negative HBV infection and compensated liver cirrhosis & minor in decompensated cirrhosis. In children with the age of 2 years or older: Used for nucleoside inhibitor therapy naïve, lamivudine resistance patients with HBeAg positive chronic HBV infection and compensated cirrhosis patients.

Works as  Entehep 1mg (Entecavir 1mg)

Entehep 1mg (Entecavir 1mg) enclose as Entecavir as an active component, a synthetic analogue of 2-deoxyguanosine has anti-viral activity against hepatitis B virus. Entecavir is triggers in-vivo into 5-triphosphate metabolite which is an active form of Entecavir. Successively, the active metabolite triphosphate form strike with natural substrate deoxyguanosine triphosphate dGTP for infusion into viral DNA. Hence infusion of the activated triphosphate metabolite of Entecavir leads to inhibition of reverse transcriptase enzyme. For viral production and transcription RT is required, thus inhibition results as cell lysis.

ADME of Entehep 1mg (Entecavir 1mg)

For chronic hepatitis B viral infection, using Entehep 1mg (Entecavir 1mg) tablets after an oral administration undergoes absorption, distribution, metabolism & elimination.

Precaution of Entehep 1mg (Entecavir 1mg)

There are two major unfavorable conditions may occur during or after discontinuation of therapy with Entehep 1mg (Entecavir 1mg) tablets. It may include as :

Hepatitis B aggravation occurs severely after therapy Lactic acidosis or hepatomegaly with steatosis.

In lactic acidosis or hepatomegaly with steatosis :

Nucleoside analogue inclusive of Entehep 1mg (Entecavir 1mg) , using alone or combination with other anti-retroviral medicines, reported has fatal cases like lactic acidosis or hepatomegaly with steatosis. This condition is majorly occurs in women, causes obesity and extended nucleoside inhibitor risk. Discontinue the therapy If this adverse effect occurs or otherwise provide supportive measures.

In hepatitis B reactivation :

This side effect occurs mostly after the stopping of anti-hepatitis B viral therapy frequently. Hepatic or liver function test should be periodically taken for the patients To avoid this condition, The patients who are getting hepatitis B infection after the treatment, recurrently will get Anti-hepatitis B viral therapy

In patients with HBV/HIV co infection : 

Entehep 1mg (Entecavir 1mg) usage is not assessed in HBV/HIV co infected patients who are not correspondingly getting anti-retroviral medication. Entehep 1mg (Entecavir 1mg) tablets used to treat chronic hepatitis B infection in HIV infected patients that are not being used if there is a possible to get advancement of resistance to HIV nucleoside reverse transcriptase inhibitors. Patient must investigate by checking the HIV antibody before starting therapy with Entecavir

Entehep 1mg (Entecavir 1mg) causes some effects due to interact with other medicines:

Concurrent use of Entehep 1mg (Entecavir 1mg) with lamivudine, Adefovir or tenofovir disoproxil fumarate cause no serious medicines interactions Some medicines may cause some effects while concomitant with Entecavir, it may follow as; Chlorpheniramine Ginkgo Biloba Aspirin Lamivudine Metoprolol Valproate sodium Paracetamol, Sorafenib, KCl in sodium chloride Hence, Entehep 1mg (Entecavir 1mg) is eliminated after metabolism through kidneys. If co administration of Entehep 1mg (Entecavir 1mg) tablets with medicines reducing the renal function may leads to cause increasing the concentration of Entecavir and produces serious adverse effects.
