Ganciclovir (Oral route, intravenous route)
The clinical toxicity of ganciclovir includes granulocytopenia, anemia, and thrombocytopenia. In animal studies ganciclovir was carcinogenic, teratogenic, and caused aspermatogenesis. Ganciclovir is indicated only for prevention of CMV disease in patients with advanced HIV infection at risk for CMV disease, for maintenance treatment of CMV retinitis in immunocompromised patients, and for prevention of CMV disease in solid organ transplant recipients. Because ganciclovir is associated with a risk of more rapid rate of CMV retinitis progression, it should be used as maintenance treatment only in those patients for whom this risk is balanced by the benefit associated with avoiding daily intravenous infusions .Intravenous route(Powder for Solution)
