Fotokathodin

Fotokathodin is a term that refers to a specific type of photodynamic therapy or photochemotherapy, often employed in dermatological and oncological treatments. The core principle involves the use of a photosensitizing agent that, when activated by light of a specific wavelength, produces reactive oxygen species. These reactive oxygen species are highly toxic to targeted cells, leading to their destruction.

The photosensitizer used in fotokathodin treatments is typically a drug that is administered either topically, orally, or intravenously. Once the drug has accumulated in the target tissue, a light source, such as a laser or a specific type of lamp, is applied to the area. The wavelength of the light is crucial and must match the absorption spectrum of the photosensitizer. Upon light exposure, the photosensitizer molecule absorbs energy and transfers it to molecular oxygen, generating cytotoxic singlet oxygen and other free radicals.

This targeted cell death mechanism makes fotokathodin a valuable treatment option for various conditions, including certain types of skin cancer, precancerous skin lesions like actinic keratosis, and some non-cancerous dermatological conditions such as acne vulgaris and rosacea. Its localized action minimizes damage to surrounding healthy tissues, which can lead to fewer side effects compared to traditional therapies like surgery or radiation. The specific protocol, including the choice of photosensitizer, light source, and treatment duration, is tailored to the individual patient and the condition being treated.
