Structure and properties
Ganciclovir (C9H13N5O4, Mr = 255.2 g/mol) is present in drugs as ganciclovir sodium, a white crystalline powder that is soluble in water. Ganciclovir itself is sparingly soluble in water. It is a nucleoside analog of 2′-deoxyguanosine. See also under the article Nucleic acids.
Effects
Ganciclovir (ATC J05AB06) has antiviral properties against herpes viruses. It is a prodrug and is phosphorylated in cells by viral and cellular kinases to ganciclovir triphosphate, which inhibits viral DNA synthesis and thus viral replication. Ganciclovir has poor oral bioavailability and is therefore also administered in the form of the prodrug valganciclovir (Valcyte), which is available perorally. Valganciclovir is hydrolyzed to ganciclovir after absorption.
Indications
