Telbivudine is a synthetic analogue of thymidine nucleoside. It acts on the DNA polymerase of hepatitis B virus. It is actively phosphorylated by cellular kinases, reaching an active triphosphate form with an intracellular half-life of about 14 hours. 

Pharmacokinetics

The process of absorption, distribution, metabolism and excretion is a pharmacokinetics. After receiving a single dose of telbivudine in 600 mg, complete absorption is observed. The maximum concentration in the blood plasma is achieved two hours after admission. The constant concentration in serum develops during 5-7 days of regular use of tablets. Absorption and systemic action do not depend on food intake. Binding to blood plasma proteins is low. Distribution of tissues and organs is equal.

After reaching the maximum concentration, the half-life begins, which takes 40-49 hours. Telbivudine is excreted unchanged in the urine. About 42% of a single dose is excreted within 7 days.

Interactions with other drugs

Sebivo is excreted mainly by the kidneys, so when it is concurrently taken with drugs that affect kidney function, an increase in the concentration of telbivudine is possible.

Pharmacokinetic properties of the drug do not change when used with Lamivudine, Dipivoxil, Peginterferon-alpha 2a or Cyclosporin. Sebivo is not recommended to be used simultaneously with interferon alpha. When monotherapy with nucleoside / nucleotide analogues of the drug or when combined with antiretroviral agents, it is possible to develop severe hepatomegaly with steatosis or lactic acidosis.
