Fomivirsen Sodium is the sodium salt form of fomivirsen, an antisense phosphorothioate oligodeoxynucleotide (ODN) with potent antiviral property. Fomivirsen is a 21-nucleotide ODN complementary to mRNA of the immediate-early region 2 of human cytomegalovirus (CMV). Hybridization of this antisense ODN to CMV mRNA prevents RNA transcription from the immediate-early region 2 gene, thereby inhibiting viral replication. In addition, this agent inhibits adsorption of CMV into host cells via a sequence-independent mechanism. Overall, fomivirsen inhibits viral propagation via inhibiting viral replication and viral uptake by host cells, hence delaying progression of CMV-associated retinitis.

4 Drug and Medication Information
4.1 Drug Indication

For the local treatment of cytomegalovirus (CMV) retinitis in patients with acquired immuno-deficiency syndrome (AIDS).

Until further experience is gained, fomivirsen should be used only when other therapy has been ineffective or is considered unsuitable.


5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Antiviral Agents

Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly. (See all compounds classified as Antiviral Agents.)


Oligonucleotides, Antisense

Short fragments of DNA or RNA that are used to alter the function of target RNAs or DNAs to which they hybridize. (See all compounds classified as Oligonucleotides, Antisense.)
