Drug Mode of Action ::  

Ganciclovir is a synthetic guanine nucleoside analogue with activity against cytomegalovirus (CMV). It competitively inhibits the binding of deoxyguanosine triphosphate to DNA polymerase, thus inhibiting viral DNA synthesis.

Drug Interactions ::

Increased risk of haematologic toxicity w/ zidovudine. May increase serum levels of didanosine. Increased serum concentration w/ probenecid and other drugs that inhibit renal tubular secretion and resorption. Use of IV ganciclovir w/ oral mycophenolate mofetil may result in increased plasma concentrations of both drugs due to competition for renal tubular secretion. Concomitant use w/ immunosuppressive agents (e.g. azathioprine, ciclosporin, corticosteroids) may result in excessive suppression of bone marrow or the immune system. Generalised seizure may occur when taken w/ imipenem and cilastatin. Concurrent use w/ drugs that inhibit replication of rapidly dividing cells (e.g. dapsone, pentamidine, pyrimethamine, flucytosine, cytotoxic antineoplastic agents, amphotericin B, co-trimoxazole, other nucleoside analogues) may result in additive toxicity.
