Cytomegalovirus Therapeutics segmentation by type is anchored in the intervention’s molecular target and clinical risk level. Antiviral drugs—ganciclovir, valganciclovir, foscarnet, and cidofovir—remain the dominant revenue block, collectively accounting for roughly 75 % of 2023 global sales because they are mandated as first-line prophylaxis and preemptive therapy in transplant units. Their share is stabilizing as generics erode unit prices, but volume grows with solid-organ transplant activity. Immune globulins (CMV-IG) occupy a narrower, high-value niche; priced at > US $2 000 per course, they contribute < 10 % of unit volume yet ~ 18 % of dollar value by reducing viral load breakthrough in seronegative recipients. Off-label antibiotics and interferons represent < 5 %; these segments persist only in salvage regimens or resource-limited settings and are forecast to contract as newer antivirals advance through phase III.
