Demand for safe excipients is growing worldwide

Today’s parenteral formulations industry is growing rapidly. In the vaccines segment, for instance, government organizations are launching increasing numbers of programs around the world to combat the rising prevalence of (infectious) diseases and the demand for excipients as safe carriers in vaccines and other injectables is higher than ever before (Kaddar, 2013). As gelatin is widely used as stabilizing excipient, Rousselot Biomedical’s X-Pure range significantly increases patient safety.

The multiple benefits of highly purified pharmaceutical gelatins in parenteral applications - including vaccines

As a biomaterial of choice, gelatin is widely recognized for its use in parenteral applications.

Highly biocompatible, purified pharmaceutical gelatin helps provide drug protection, offers superior drug loading rates, and great flexibility in the control of drug release. It helps stabilize vaccines and other formulations and minimizes side reactions while ensuring patient safety. These are just few examples of the many benefits provided by purified gelatins.

Read our white paper which explores these various advantages and describes how X-Pure® extra purified GMP quality gelatins can help realize superior parenteral formulations.

X-Pure Gelatin for vaccines

Pharmaceutical gelatin is a key excipient used in many vaccine formulations. It generally offers an effective strategy to improve stability of lyophilized products and is a preferred stabilizer in many vaccines. Well-known examples include Fluenz Tetra (Astra Zeneca), MMR-II and MMR VaxPro (Merck), VariVax (Merck), YF-Vax (Sanofi) and Zostavax (Merck). In the case of Fluenz, the formulation using hydrolyzed gelatin achieved significantly superior stability over a large number of alternative stabilizers evaluated.

X-Pure is ideally suited for use in such applications where lyophilization stability is required as it is also available in a hydrolyzed and non-gelling form, has well controlled endotoxin levels below 10 EU/g, and ensured batch to batch consistency.
