The "Fragile Package" Problem
Biopharmaceuticals are made of complex proteins. Unlike a chemical pill, these proteins can "unfold" or clump together if they get too warm, too cold, or are shaken too much.
The Stabilizer’s Job: Excipients act like a "cradle" for these proteins. They wrap around the medicine to keep it in its correct shape.
Temperature Shielding: In 2026, special excipients (like certain sugars) allow some vaccines to stay safe even if they aren't kept in a freezing-cold refrigerator.
The "Anti-Clump" Guard: If protein medicines clump together, they can become dangerous. Excipients called "surfactants" act like a non-stick coating to keep the medicine smooth and liquid.
