Mechanism of action

TOOKAD (palladium bacteriopheophorbide) is a photosensitizer that, when activated by near-infrared light, produces singlet oxygen and reactive oxygen species that selectively damage tumor blood vessels, leading to tumor necrosis. The drug is administered intravenously and then activated by transurethral light delivery, making it particularly suited for localized tumors accessible to light delivery.
