Pharmacological action

Cymeven is an antiviral agent. Ganciclovir is a synthetic analogue of 2′-deoxyguanosine, which inhibits the multiplication of herpes viruses in vitro and in vivo. Ganciclovir-sensitive viruses include human cytomegalovirus (h-CMV), herpes simplex viruses -1 and -2 (Herpes simplex 1 and 2), human herpes virus type 6, 7 and 8 (HHV-6, HHV-7, HHV-8), Epstein-Barr virus (EBV), chickenpox virus (Varicella / zoster) and hepatitis B virus. Clinical studies have been limited to evaluating the effectiveness of the drug in patients infected with cytomegalovirus.

In CMV-infected cells, ganciclovir is first phosphorylated by the action of a viral protein kinase to form ganciclovir monophosphate. Further phosphorylation occurs under the action of several cellular kinases, resulting in the formation of ganciclovir triphosphate, which then undergoes slow intracellular metabolism. This metabolism has been shown to occur in cells infected with human CMV and herpes simplex virus, after the disappearance of ganciclovir from the extracellular fluid, the intracellular half-life of the drug is 18 and 6-24 hours, respectively. Since the phosphorylation of ganciclovir is more dependent on the action of the viral kinase, it occurs predominantly in infected cells.

The virologostatic effect of ganciclovir is due to the suppression of viral DNA synthesis by: (1) competitive inhibition of the incorporation of deoxyguanosine triphosphate into DNA under the influence of DNA polymerase (2) incorporation of ganciclovir triphosphate into viral DNA, leading to termination of the extension of the viral DNA or its very limited extension. A typical CMV antiviral IC50, determined in vitro, is in the range of 0.14 μM (0.04 μg / ml) to 14 μM (3.5 μg / ml).


Hypersensitivity to Cymevene, valganciclovir, or any other component of the drug.

Due to the similarity of the chemical structure of Cymeven and acyclovir and valacyclovir, cross-hypersensitivity reactions are possible between these drugs.

The absolute neutrophil count is less than 500 cells in 1 В l, or the platelet count is less than 25,000 cells in 1 В l, or the hemoglobin level is less than 8 g / dl.

Children under 12 years old.

Use during pregnancy and lactation

During treatment with ganciclovir, women of childbearing age should be advised to use reliable methods of contraception. Men are recommended to use the barrier method of contraception during treatment and at least 90 days after its completion.

In animal studies teratogenicity of the drug was revealed. The safety of ganciclovir during pregnancy in humans has not been established. Prescribing the drug to pregnant women should be avoided unless the potential beneficial effect for the mother does not exceed the possible risk to the fetus.

Peri- and postnatal development after exposure to ganciclovir has not been studied, but it cannot be ruled out that ganciclovir may be excreted in milk and cause serious adverse reactions in the infant. Consequently, a decision to discontinue the drug or to stop breastfeeding should be made taking into account the potential positive effect of ganciclovir for a nursing mother.

Special instructions

Ganciclovir has a potential teratogenic and carcinogenic effect and may cause congenital malformations and malignant neoplasms. Ganciclovir may temporarily or permanently inhibit spermatogenesis (see Pregnancy and Side Effects).

Cases of severe leukopenia, neutropenia, anemia, thrombocytopenia, pancytopenia, myelosuppression, and aplastic anemia have been observed in patients taking ganciclovir. Ganciclovir treatment should not be started if the absolute number of neutrophils is less than 500 cells in 1 Ојl, or platelet count less than 25,000 cells in 1 Ојl, or hemoglobin level less than 8 g / dl (see Special dosage instructions and Adverse effects).

During treatment, it is recommended to monitor the expanded blood count, including platelet count. In patients with severe leukopenia, neutropenia, anemia and / or thrombocytopenia, it is recommended that hematopoietic growth factors be treated and / or temporarily discontinue therapy with the drug.

In case of impaired renal function, it is recommended to adjust the dose of the drug depending on the creatinine clearance.

Seizures are described in patients taking imipenem / cilastatin and ganciclovir, therefore ganciclovir should not be given concomitantly with imipenem / cilastatin, unless the potential benefits of therapy exceed the possible risk (see Drug Interactions).

Both ganciclovir and zidovudine can cause neutropenia and anemia, so some patients may not tolerate the simultaneous use of these drugs in full doses (see Drug Interactions).

While taking ganciclovir, plasma concentrations of didanosine may increase, so such patients should be carefully monitored for didanosine toxicity phenomena (see Drug Interactions). The simultaneous administration of ganciclovir and drugs with myelosuppressive or nephrotoxic effects can lead to the development of additive toxicity.
