Phthalates are chemical compounds classified as endocrine disruptors which are present in practically every environment of daily life. In the field of artificial nutrition, they are relevant because they are found as plasticizers in infusion lines made with PVC. They are lipophilic molecules which weakly pair with PVC and, therefore, they are easily extracted by the fatty compounds that are part of both the parenteral and enteral nutrition, as various studies show. As endocrine disruptors, they directly affect the reproductive organs because of their antiandrogenic and estrogenic effects. They promote inflammation and oxidative stress and they are also related to the development of obesity, asthma, neurological and ophthalmic disorders, cholestasis and other gastrointestinal disorders. The legislation establishes the highest recommended exposure level for daily exposure; however, in the medical environment the exposure follows a different pattern, more occasional with very high peaks, for which there are no established thresholds, that is why it is recommended to avoid exposure whenever possible. The industry is working on the development of alternative plasticizers, for which the use experience is still limited. Currently, in the field of artificial nutrition it is recommended to use phthalate-free intravenous and enteral infusion lines.
