- Pharmacodynamics
Telbivudine is a synthetic thymidine nucleoside analogue with activity against hepatitis B virus (HBV). Telbivudine is the unmodified β–L enantiomer of the naturally occurring nucleoside, thymidine. It undergoes phosphorylation via interaction with cellular kinases to form the active metabolite, telbivudine 5'-triphosphate.
- Mechanism of action
Telbivudine 5'–triphosphate inhibits HBV DNA polymerase (reverse transcriptase) by competing with the natural substrate, thymidine 5'–triphosphate. This leads to the chain termination of DNA synthesis, thereby inhibiting viral replication. Incorporation of telbivudine 5'–triphosphate into viral DNA also causes DNA chain termination, resulting in inhibition of HBV replication. Telbivudine inhibits anticompliment or second-strand DNA.
Target Actions Organism ADNA Not Available Humans AProtein P Not Available HBV-F - Absorption
Absorbed following oral administration. Telbivudine absorption and exposure were unaffected when a single 600–mg dose was administered with a high–fat (~55 g), high–calorie (~950 kcal) meal.
- Volume of distribution
Not Available
- Protein binding
In vitro binding of telbivudine to human plasma proteins is low (3.3%).
- Metabolism
No metabolites of telbivudine were detected following administration of [14C]–telbivudine in humans. Telbivudine is not a substrate, or inhibitor of the cytochrome P450 (CYP450) enzyme system.
- Route of elimination
Telbivudine is eliminated primarily by urinary excretion of unchanged drug.
- Half-life
Approximately 15 hours.
- Clearance
- 7.6 +/- 2.9 L/h [Normal renal function (Clcr>80 mL/min)]
- 5.0 +/- 1.2 L/h [Mild renal function impairement (Clcr=50-80 mL/min)]
- 2.6 +/- 1.2 L/h [Moderate renal function impairement (Clcr=30-49 mL/min)]
- 0.7 +/- 0.4 L/h [Severe renal function impairement (Clcr<30 mL/min)]

- Toxicity
There is no information on intentional overdose of telbivudine, but one subject experienced an unintentional and asymptomatic overdose. Healthy subjects who received telbivudine doses up to 1800 mg/day for 4 days had no increase in or unexpected adverse events. A maximum tolerated dose for telbivudine has not been determined.

- General Function
- Multifunctional enzyme that converts the viral RNA genome into dsDNA in viral cytoplasmic capsids. This enzyme displays a DNA polymerase activity that can copy either DNA or RNA templates, and a ribonuclease H (RNase H) activity that cleaves the RNA strand of RNA-DNA heteroduplexes in a partially processive 3'- to 5'-endonucleasic mode. Neo-synthesized pregenomic RNA (pgRNA) are encapsidated together with the P protein, and reverse-transcribed inside the nucleocapsid. Initiation of reverse-transcription occurs first by binding the epsilon loop on the pgRNA genome, and is initiated by protein priming, thereby the 5'-end of (-)DNA is covalently linked to P protein. Partial (+)DNA is synthesized from the (-)DNA template and generates the relaxed circular DNA (RC-DNA) genome. After budding and infection, the RC-DNA migrates in the nucleus, and is converted into a plasmid-like covalently closed circular DNA (cccDNA). The activity of P protein does not seem to be necessary for cccDNA generation, and is presumably released from (+)DNA by host nuclear DNA repair machinery.
