FAQ

Can my pharmaceutical product be freeze-dried?

Whether a pharmaceutical product is suitable for freeze-drying depends on its heat sensitivity and stability requirements. The following pharmaceutical products are generally well-suited for freeze-drying:

1. Biologics: Vaccines, antibodies, proteins, peptides, enzymes, hormones, and other highly temperature-sensitive active substances—freeze-drying is the gold standard process for maintaining their long-term activity.

2. Antibiotics: Such as penicillins and cephalosporins, which can address the issue of potency decline in humid and hot environments.

3. Diagnostic reagents: Products that require the preservation of activity, such as enzyme-linked immunosorbent assay (ELISA) kits and nucleic acid detection kits.

How does freeze-drying technology improve drug stability?

Freeze-drying stabilizes drugs at the molecular level through a dual mechanism of water removal and low-temperature processing:

1. Inhibiting hydrolysis reactions: Water serves as both a medium and a reactant in many degradation reactions. Freeze-drying reduces water content to 1%–3%, physically blocking chemical degradation pathways such as hydrolysis and oxidation, thereby preserving the drug’s chemical integrity.

2. Inhibits microbial growth: Extremely low water activity creates an environment where microorganisms cannot survive, preventing biological spoilage.

3. Protects heat-sensitive molecular structures: Processing at low temperatures throughout (typically below -40°C) prevents structural damage—such as protein denaturation and antibody inactivation—caused by high temperatures.

4. Forms a stable physical form: Freeze-drying produces a loose, porous, sponge-like “cake” with a large specific surface area and stable physicochemical properties, capable of maintaining efficacy for several years at room temperature.

5. Rapid rehydration: The porous structure allows for complete rehydration within seconds upon contact with a solvent, restoring the original therapeutic efficacy.
