Mechanism of action

Ganciclovir is a synthetic analogue of 2'-deoxy-guanosine. It is first phosphorylated to a deoxyguanosine triphosphate (dGTP) analog. This competitively inhibits the incorporation of dGTP by viral DNA polymerase, resulting in the termination of elongation of viral DNA. The chemical structure of Guanosine Guanosine is a nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N9-glycosidic bond. ... A phosphorylated serine residue Phosphorylation is the addition of a phosphate (PO4) group to a protein or a small molecule or the introduction of a phosphate group into an organic molecule. ...

Adverse effects

Ganciclovir is commonly associated with a range of serious haematological adverse effects. Common adverse drug reactions (≥1% of patients) include: granulocytopenia, neutropenia, anaemia, thrombocytopenia, fever, nausea, vomiting, dyspepsia, diarrhoea, abdominal pain, flatulence, anorexia, raised liver enzymes, headache, confusion, hallucination, seizures, pain and phlebitis at injection site (due to high pH), sweating, rash, itch, increased serum creatinine and blood urea concentrations.[1] Hematology is the branch of medicine that is concerned with blood and its disorders. ... An adverse drug reaction (abbreviated ADR) is a term to describe the unwanted, negative consequences sometimes associated with the use of medications. ...

Urea is also known as carbamide, especially in the recommended International Nonproprietary Names (rINN) in use in Europe. ...


Ganciclovir is considered a potential human carcinogen, teratogen, and mutagen. It is also considered likely to cause inhibition of spermatogenesis. Thus, it is used judiciously and handled as a cytotoxic drug in the clinical setting.[1][2] The hazard symbol for carcinogenic chemicals in the Globally Harmonized System. ... Teratogenesis is a medical term from the Greek, literally meaning monster making. ... In biology, a mutagen (Latin, literally origin of change) is a physical or chemical agent that changes the genetic information (usually DNA) of an organism and thus increases the number of mutations above the natural background level. ... This article or section is in need of attention from an expert on the subject. ... Chemotherapy (pronounced keem-o-therapy) is the use of certain drugs to treat disease, as distinct from other forms of treatment, such as surgery. ...


Absorption of the oral form is very limited - about 5% fasting, about 8% with food. It achieves a concentration in the central nervous system of about 50% of the plasma level. About 90% of plasma ganciclovir is eliminated unchanged in the urine, with a half-life of 2-6 hrs, depending on renal function (elimination takes over 24 hours in end-stage renal disease). A diagram showing the CNS: 1. ... Blood plasma is the liquid component of blood, in which the blood cells are suspended. ... This article or section is in need of attention from an expert on the subject. ... Half-Life For a quantity subject to exponential decay, the half-life is the time required for the quantity to fall to half of its initial value. ... In medicine (nephrology) renal function is an indication of the state of the kidney and its role in physiology. ...


Acute infections are treated in two phases:

  • induction phase, 5 mg per kilogram intravenously every 12 hours for 14-21 days, the intravenous dose given as a 1 hour infusion
  • maintenance phase, 5 mg per kg intravenously every day

Stable disease is treated with 1000 mg orally three times daily. Similar dosing is used to prevent disease in high-risk patients, such as those infected with human immunodeficiency virus (HIV) or those with organ transplants.

Ganciclovir is also available in slow-release formulations for insertion into the vitreous humour of the eye, as treatment for CMV retinitis (associated with HIV infection). Vitreous humour is the clear aqueous solution that fills the space between the lens and the retina of the vertebrate eyeball. ... A human eye Eyes are organs of vision that detect light. ...

The effects of dexamethasone on cell proliferation and sensitivity to ganciclovir were assessed with a thymidine incorporation assay and a MTT test.
Ganciclovir monophosphate is subsequently bis and tri-phosphorylated by cellular kinases and is then incorporated in the DNA of replicating cells, blocking the cell cycle and inducing apoptosis [1,4,5].
The reasons why ganciclovir failed to enhance the toxicity of sFAS-L on U87-TK cells remain unknown and are beyond the scope of the present work, as is the thorough assessment of the effects of dexamethasone on HSV-TK/GCV-induced apoptosis.
