Triapten

Triapten Uses, Dosage, Side Effects, Food Interaction and all others data.

An antiviral agent used in the treatment of cytomegalovirus retinitis. Triapten also shows activity against human herpes viruses and HIV.

Triapten is an organic analogue of inorganic pyrophosphate that inhibits replication of herpes viruses in vitro including cytomegalovirus (CMV) and herpes simplex virus types 1 and 2 (HSV-1 and HSV-2). Triapten does not require activation (phosphorylation) by thymidine kinase or other kinases and therefore is active in vitro against HSV TK deficient mutants and CMV UL97 mutants. Thus, HSV strains resistant to acyclovir or CMV strains resistant to ganciclovir may be sensitive to foscarnet. However, acyclovir or ganciclovir resistant mutants with alterations in the viral DNA polymerase may be resistant to foscarnet and may not respond to therapy with foscarnet. The combination of foscarnet and ganciclovir has been shown to have enhanced activity in vitro.

Uses

Triapten is an antiviral used to treat CMV, HIV, and HSV infections.

For the treatment of CMV retinitis in patients with acquired immunodeficiency syndrome (AIDS) and for treatment of acyclovir-resistant mucocutaneous HSV infections in immunocompromised patients.

Triapten is also used to associated treatment for these conditions: Chickenpox, Cytomegalovirus Retinitis, Genital Herpes, Herpes Labialis, Herpetic whitlow

How Triapten works

Triapten exerts its antiviral activity by a selective inhibition at the pyrophosphate binding site on virus-specific DNA polymerases at concentrations that do not affect cellular DNA polymerases.

Toxicity

Oral, rat LD50: >2,000 mg/kg. Signs of overdose include renal impairment.

Food Interaction

No interactions found.

Elimination Route

Poorly absorbed after oral administration (bioavailability from 12 to 22%).

Half Life

3.3-6.8 hours

Clearance

  • 2.13 +/- 0.71 mL/min/kg [patients had normal renal function (CrCl > 80 mL/min]
  • 68 +/- 8 mL/min/kg [CrCl was 50-80 mL/min]
  • 34 +/- 9 mL/min/kg [CrCl was 25-49 mL/min]
  • 20 +/- 4 mL/min/kg [CrCl was 10 - 24 mL/min]
