At a glance
Telbivudine is a synthetic thymidine nucleoside analog used for the treatment of chronic hepatitis B virus (HBV) infection. It inhibits HBV DNA polymerase to stop viral replication.
Indications
- Chronic hepatitis B (HBeAg-positive and HBeAg-negative, compensated liver disease)
Pharmacology
Telbivudine is phosphorylated by cellular kinases to form telbivudine 5'-triphosphate. It competes with the natural substrate thymidine triphosphate for HBV DNA polymerase, incorporating into viral DNA and causing chain termination, inhibiting viral replication.
Dosage
Adult and Adolescent (≥16 years) Dose (Oral):
- Recommended: 600 mg once daily
- HBeAg-positive: Initiate if HBV DNA <9 log10 copies/mL and ALT ≥2x ULN
- HBeAg-negative: Initiate if HBV DNA <7 log10 copies/mL
- Monitor HBV DNA at 24 weeks; consider alternative therapy if detectable
Side effects
Common Side Effects:
- Fatigue, headache, nausea
- Decreased appetite, diarrhea, abdominal pain
- Muscle pain, joint pain
- Insomnia, rash, fever
