Valganciclovir
Identification
- Summary
Valganciclovir is an antiviral medication used to treat cytomegalovirus (CMV) retinitis in patients diagnosed with acquired immunodeficiency syndrome (AIDS).
- Brand Names
- Valcyte
- Generic Name
- Valganciclovir
- DrugBank Accession Number
- DB01610
- Background
Valganciclovir hydrochloride (Valcyte, manufactured by Roche) is an antiviral medication used to treat cytomegalovirus infections. As the L-valyl ester of ganciclovir, it is actually a prodrug for ganciclovir. After oral administration, it is rapidly converted to ganciclovir by intestinal and hepatic esterases.

- Pharmacodynamics
Valganciclovir is an antiviral medication used to treat cytomegalovirus infections. As the L-valyl ester of ganciclovir, it is actually a prodrug for ganciclovir. After oral administration, it is rapidly converted to ganciclovir by intestinal and hepatic esterases. After this, it (being an analogue of guanosine) gets incorporated into DNA and thus cannot be properly read by DNA polymerase. This results in the termination of the elongation of viral DNA.
- Mechanism of action
Valganciclovir is a prodrug of ganciclovir that exists as a mixture of two diastereomers. After administration, these diastereomers are rapidly converted to ganciclovir by hepatic and intestinal esterases. In cytomegalovirus (CMV)-infected cells, ganciclovir is initially phosphorylated to the monophosphate form by viral protein kinase, then it is further phosphorylated via cellular kinases to produce the triphosphate form. This triphosphate form is slowly metabolized intracellularly. The phosphorylation is dependent upon the viral kinase and occurs preferentially in virus-infected cells. The virustatic activity of ganciclovir is due to the inhibition of viral DNA synthesis by ganciclovir triphosphate. Ganciclovir triphosphate is incorporated into the DNA strand replacing many of the adenosine bases. This results in the prevention of DNA synthesis, as phosphodiester bridges can longer to be built, destabilizing the strand. Ganciclovir inhibits viral DNA polymerases more effectively than it does cellular polymerase, and chain elongation resumes when ganciclovir is removed.
Target Actions Organism ADNA adductHumans - Absorption
Valganciclovir is well absorbed from the gastrointestinal tract and the absolute bioavailability from valganciclovir tablets (following administration with food) is approximately 60%.
- Volume of distribution
- 0.703 ± 0.134 L/kg
- Protein binding
Plasma protein binding of ganciclovir is 1% to 2% over concentrations of 0.5 and 51 mg/mL.
- Metabolism
Rapidly hydrolyzed in the intestinal wall and liver to ganciclovir. No other metabolites have been detected.
- Route of elimination
The major route of elimination of valganciclovir is by renal excretion as ganciclovir through glomerular filtration and active tubular secretion.
- Half-life
Approximately 4.08 hours. Increased in patients with renal function impairment.
- Clearance
- 3.07+/- 0.64 mL/min/kg [IV administration]
- 5.3 L/hr [Patient with creatinine clearance of 70.4 mL/min]

- Toxicity
It is expected that an overdose of valganciclovir could also possibly result in increased renal toxicity.

Drug Interaction Integrate drug-drug
interactions in your softwareAbacavir The risk or severity of cytopenia can be increased when Valganciclovir is combined with Abacavir. Aceclofenac Aceclofenac may decrease the excretion rate of Valganciclovir which could result in a higher serum level. Acemetacin Acemetacin may decrease the excretion rate of Valganciclovir which could result in a higher serum level. Acetaminophen Acetaminophen may decrease the excretion rate of Valganciclovir which could result in a higher serum level. Acetazolamide Acetazolamide may increase the excretion rate of Valganciclovir which could result in a lower serum level and potentially a reduction in efficacy. - Food Interactions
