From plasma to proteins: new therapeutic methods for increasingly personalised medical care.

Biopharmaceuticals are products made with living cells or extracted from living organisms, and include three main categories: substitution proteins, therapeutic antibodies and vaccines. Designed for the treatment of rare illnesses, they are administered using intravenous therapy. Because these sensitive molecules do not tolerate the heat of terminal sterilisation, aseptic filling is essential, entailing the use of sterile bags in order to guarantee the stability and integrity of the medication.

Medication derived from the blood and blood plasma is used in emergency medical treatment, intensive care and illnesses that are often chronic. Plasma, the liquid part of the blood, contains more than 300 different proteins. Separated from the blood by centrifugation, it is packaged in EVA bags. The plasma is then divided up into therapeutic proteins, antibodies and albumins, for which the first layer of packaging must also be sterile before filling.
