yhteisovaikutuksia
Yhteisvaikutuksia refers to the synergistic or antagonistic effects that occur when multiple substances or factors interact within a biological system. This concept is particularly relevant in pharmacology and toxicology, where it describes how the combined action of two or more drugs or chemicals can be different from the sum of their individual effects. Synergistic effects occur when the combined effect is greater than the sum of the individual effects, meaning that the interaction enhances the outcome. Conversely, antagonistic effects happen when the combined effect is less than the sum of the individual effects, where the interaction diminishes the outcome.
These interactions can occur at various levels, including absorption, distribution, metabolism, and excretion of substances. For
