REXIM®

Amino acids for parenteral nutrition.

With a global reach, Evonik is the leading European expert in pharmaceutical amino acids, and amino acid derivatives.

Amino acids play such a fundamental role in our lives – they make up the proteins that in turn compose much of human and animal tissue, and they are key to ensuring cell growth, repair and maintenance. For this reason, we at Evonik value quality above all in our products and processes, in our services and in the relationship we build with our customers.

In more than six decades of specialization, we have acquired a broad and deep understanding of the building blocks of life that is unparalleled in the industry. Here, our extensive experience in chemistry, biotechnology and purification technology enables us to meet any product challenge. At the same time, together with our customers, we are continuously pushing the frontier in research, analytics and technology to realize the potential of amino acids and their derivatives for improving health and productivity.

Parenteral nutrition
Excipients

Parenteral nutrition does not just depend on highly soluble amino acid forms. Microbiological purity – including strict endotoxin tolerances – is also vital. As products used for these applications effectively act as active pharmaceutical ingredients (APIs), REXIM® ensures compliance with cGMP (Current Good Manufacturing Practice) regulations, and provides all relevant documentation, such as Certificates of Suitability and Drug Master Files (DMF).

Today, medicines are available in many dosage forms including tablets, capsules, oral liquids, topical creams and gels, transdermal patches, injectable products, implants, eye products, nasal products, inhalers and suppositories. Pharmaceutical excipients are substances that are included in a pharmaceutical dosage form not for their direct therapeutic action, but to aid the manufacturing process, to protect, support or enhance stability, or for bioavailability or patient acceptability. They may also assist in product identification and enhance the overall safety or function of the product during storage or use.

Evonik offers a broad range of amino acids with proven efficacy as excipients.

Amino acids can be used to stabilize the native conformation of proteins, via a variety of mechanisms such as preferential exclusion, direct protein binding, buffering capacity and antioxidant properties.

Amino acids as excipients in oral formulations:

anti-oxidant / preservations
sweetener
co-amorphous excipients
crystallization inhibitors

Amino acids as excipients in parenteral formulations:

preservation of shelf life of proteins
crystallization inhibitors
bulking agent in lyophilized products
