Hepatitis B Medicine
Antivirals Aim To Reduce The Global Hepatitis Burden
Millions carry Hepatitis B unknowingly as it often remains asymptomatic, but left untreated, it leads to severe liver inflammation, damage, fibrosis, and cirrhosis.
✨ Antiviral therapies target viral DNA to suppress replication, lower viral load, and improve liver function.
About Hepatitis B Stages
Hepatitis can be both viral (caused by 5 distinct viruses, with B and C being the most lethal) and non-viral (caused by alcohol, autoimmune, or metabolic disorders). Transmission occurs via unprotected sex, mother to child, body fluids, and needles.
Acute Hepatitis B
The first stage of infection. It may last up to 6 months and often resolves on its own without long-term damage.
Chronic Hepatitis B
A serious long-term condition where the immune system is unable to clear the virus, leading to progressive liver damage.
Transmission Modes
Hepatitis B is highly transmissible through infected body fluids (vaginal/seminal), blood transfusions, shared needles, and from mother to child in the womb.
Antiviral DNA Targets
Modern therapies suppress viral replication, prevent cirrhosis and liver cancer progression, and significantly reduce transmission risk.
Antivirals for Hepatitis B
Nucleot(s)ide Reverse Transcriptase Inhibitors (NRTIs) competitively bind to the DNA elongation chain and inhibit HBV polymerase.
First-Line NRTIs
Strongly preferred due to high activity in lowering viral load, high safety/tolerability profiles, and low resistance rates.
Older Antivirals
Earlier generation therapeutics that are less commonly used today due to safety concerns and higher resistance profiles.
Other NRTI Agents
Additional nucleoside reverse transcriptase inhibitors used in specific combination therapies for chronic infection.
Immunomodulators
Biologics that stimulate the host immune system to fight the virus, though usage is limited due to systemic side effects.
Curbing Drug Resistance in CHB
Because the HBV virus mutates rapidly, prolonged therapy carries a risk of resistance. Combating this requires a strict, structured approach.
Use First-Line Drugs
Always initiate therapy with high-potency drugs like Entecavir or Tenofovir which have very low resistance rates.
Combination & Monitoring
Utilize combination therapies when indicated, and perform regular monitoring of viral load to detect early resistance.
Strict Treatment Adherence
Strictly adhere to the prescribed daily schedule. Missing doses allows the virus to replicate and mutate.
Early Resistance Detection
Detect resistance early and swap or add complementary antivirals if the viral load fails to remain suppressed.
