Prescribing information of HepBest

The most frequently used anti-viral agent like Tenofovir Alafenamide is primarily indicated for the treatment of chronic hepatitis B viral infection occurred in adults patient with compensated liver damage.

Mechanism of HepBest

HepBest worked in the body by some component incorporates;

For the most part HepBest containing tenofovir Alafenamide is a prodrug which is changed over into dynamic frame in-vivo

Tenofovir Alafenamide has cell penetrability property which is lipophilic in nature, infiltrates into hepatocytes by latent dissemination strategy and additionally by hepatic return transporters OATP1B1 and OATP1B3

In-vivo, tenofovir Alafenamide is changed into tenofovir a parent compound by experiencing hydrolysis with the chemical carboxylesterase 1 which is happen in hepatocytes cell

This dynamic frame tenofovir is phosphorylated into tenofovir diphosphate by cell kinase compounds

TAF has pharmacologically dynamic compound known as tenofovir diphosphate which is in charge of viral multiplication denial by means of imbuing into infection DNA with the assistance of turnaround transcriptase chemical which causes viral DNA chain end

Absorption

Maximum plasma concentration time of TAF 0.48 hours

Distribution

TAF is largely bound to human plasma protein at 80%

Protein binding data occurs in vivo

The blood plasma ratio of TAF is 1.0

Metabolism

The metabolism of TAF occurs with the help of;

Carboxyl esterase 1

Cathepsin A

CYP3A

Excretion

Nearly 80% of TAF get metabolized and reaches its half life at 0.51 hour

<1% of metabolite released through urine

31.7% excreted via feces

Drug- drug interaction of HepBest

HepBest tablets with P-gp or BCRP inhibiting drugs, causes variation in absorption of TAF; this may leads to adverse effects.

HepBest tablets with P gp or BCRP inducing drugs causes depletion of absorption of TAF leads to increasing the concentration of TAF

HepBest tablets with renal function reducing drugs may leads to increasing the concentration and causes serious adverse effects

HepBest tablet combined with anti-convulsants leads to decreasing the effect of concentration of TAF

HepBest tablet combined with anti-mycobacterials causes reducing the effect of concentration of TAF

HepBest tablets concomitant use of herbal product like st, John’s wort, causes decreasing the TAF concentration.

Food drug interaction of HepBest;

Minor food drug interaction may occur; alcohol containing food items should not be suggested.

Consult with physician about the dietary.

Possible contraindications of HepBest

No specific contraindication occurs, if some patients may contraindicate to TAF causes anaphylactic reactions.

Safety measures

Aggravation of hepatitis B infection: Check the patient history before starting the treatment

Exposure of advancement of HIV-1 resistance: Due to this condition, HepBest tablets are not suggested for HIV-1 infections

New commencement of renal damage: To avoid concomitant use of HepBest with renal function depleting drugs

Lactic acidosis or hepatomegaly with steatosis: Stop the therapy with HepBest

Pregnancy and lactation

HepBest tablets are probably used in pregnancy conditions, only after knowing the risk of the product associated to fetus.

Breast feeding should not be suggested.
