fototoksisuus
Fototoksisuus refers to a toxic reaction that occurs when certain substances are exposed to light. This interaction can damage cells or tissues, leading to a harmful response within the body. The mechanism typically involves a photosensitizing agent that absorbs light energy and then transfers this energy to surrounding molecules, often oxygen, creating reactive oxygen species. These highly reactive molecules can then cause cellular damage through oxidation.
In humans, fototoksisuus can manifest in various ways, most commonly as skin reactions. When a photosensitizing
Common causes of fototoksisuus include certain medications, such as some antibiotics, diuretics, and nonsteroidal anti-inflammatory drugs,
