In decompensated condition, the suggested dosage is 1mg of Entaliv should be taken as once a day.In renal damaged patients
If creatinine clearance decreased, then the apparent oral clearance of Entaliv is also decreased.
The dosage recommendation for the patients;
With creatinine clearance of less than 50ml/min,
Hemodialysis patients and
For Continuous ambulatory peritoneal dialysis patients (CAPD)
CrCl ≥50ml/min: 0.5mg of Entaliv should be recommended; in lamivudine resistant or decompensated condition 1mg of Entaliv is recommend.
In 30 to <50ml/min: 0.5mg of Entaliv is taken for every 48 hours; in lamivudine resistant or decompensated condition 0.5mg of Entaliv as single dose or 1mg of Entaliv taken for every 48 hours. In 10 to <30ml/min: 0.5mg of Entaliv should be given for every 72 hours; in lamivudine resistant or decompensated condition 1mg of Entaliv is recommended for every 72 hours. <10ml/min: & hemodialysis or CAPD: 0.5mg of Entaliv is recommended for every 7 days; in lamivudine resistant or decompensated condition 1mg of Entaliv should be given for every 7 days.

The most common adverse reaction occurs during or after the treatment; Severe aggravation of hepatitis B infection, Lactic acidosis, Hepatomegaly with steatosis, The common side effects like, Dyspepsia, Alopecia, Rash, Elevation of transaminase, Headache, Fatigue, Anaphylactic reactions, Dizziness, Diarrhea, Nausea, Vomiting, Somnolence, Insomnia, Hepatic failure, Gastrointestinal hemorrhage, Hepatocellular carcinoma
Some precautions should be taken while starting therapy with EntalivIn severe acute aggravation of hepatitis B:
This adverse may occur after discontinuation of anti-hepatitis B therapy. In this condition patient should be monitored frequently with liver functions and other laboratory follow ups. Continue the anti-hepatitis B therapy, if required.In HBV/HIV-1 co infected patients
Entecavir has not assessed in HIV/HBV co infected patients who are not concurrently taking effective anti-retroviral therapy. Entaliv 1mg tablet used for HBV infection in patients who are infected with HIV, produce resistant to HIV nucleoside reverse transcriptase inhibitors, not exist to treat. Entaliv 1mg should not be suggested to HBV/HIV co infected patients, also not receiving HAART. To overcome this type of condition, patient should be examining with HIV antibody testing before the therapy.In lactic acidosis & hepatomegaly with steatosis
This condition may occur due to the combination of nucleoside analog with anti-retroviral agents, this may happen mostly in women. The major fatal cases of this condition are obesity and extended nucleoside exposure. Lactic acidosis frequently occurs in decompensated liver cirrhosis patients, the only way to reduce this adverse is discontinuing the treatment with Entaliv 1mg.
Entaliv 1mg is not a CYP 450 enzyme substrate, inhibitor or inducers.
Since Entaliv 1mg is majorly eliminated through kidneys, co administration of Entaliv tablets with drugs which reduce the renal functions causes increasing the serum concentration of Entecavir and other combined drugs leads to adverse effects of Entaliv.
Drug interaction may occur during combination of Entaliv 1mg with the drugs which metabolized, inhibit or induce by CYP450 enzyme may have chance to alter pharmacokinetic properties of Entecavir. Co administration of Entaliv 1mg with lamivudine, Adefovir or tenofovir disoproxil fumarate not expels any drug interaction.
