About
Ganciclovir, often associated with products like Cymgal, is an antiviral medication primarily used to treat and prevent cytomegalovirus (CMV) infections. It functions by inhibiting viral DNA synthesis, thereby effectively preventing the replication of the CMV virus within infected cells. This nucleoside analogue is phosphorylated intracellularly to its active form, ganciclovir triphosphate, which then competes with deoxyguanosine triphosphate for incorporation into viral DNA, leading to chain termination and inhibition of viral DNA polymerase. It is particularly crucial in immunocompromised patients, such as those with HIV/AIDS or organ transplant recipients, where CMV infections can be severe and life-threatening. Its clinical application extends to various manifestations of CMV disease, including retinitis, colitis, and esophagitis, offering vital therapeutic intervention.
