Injectable delivery of small molecules

Discover our vast portfolio of parenteral offerings used specifically in the injectable delivery of small molecules. 

One category of our injectable excipient portfolio includes lipids. Lipid excipients play a pivotal role in enhancing the parenteral delivery of small molecule APIs by facilitating the formation of liposomes. Liposomes provide a stable and biocompatible carrier system for the encapsulation and solubilization of both hydrophobic and hydrophilic drug compounds. This unique capability not only improves the drug's bioavailability but also ensures a controlled and sustained release, optimizing therapeutic outcomes.

Liposomal drug delivery has shown proven efficacy in various small molecule applications, including pain management drugs as well as cancer therapies. The ability of liposomes to encapsulate drugs makes them an ideal choice for targeted delivery, addressing the specific challenges associated with these critical therapeutic areas. Our dedicated focus on developing cutting-edge lipid excipients underscores our commitment to advancing the field of injectable drug delivery, providing pharmaceutical developers with reliable solutions for formulating next-generation small molecule drugs.

Super Refined™ excipients for Small Molecule Delivery

Formulation challenges are not uncommon in pharmaceutical formulation, frequent challenges include the use of highly unstable APIs and excipient-drug interaction. 

Our Croda experts have designed our Super Refined™ excipients to combat formulation challenges and to provide additional value to your final drug product. Our range of emulsifiers, permeation enhancers, emollients and solvents enhance stability and have a variety of formulation benefits including:

  • Minimised API degradation
  • Reduced impurity profiles for improved drug compatibility
  • Reduced oxidation potential for increased drug stability
  • Batch-to-batch consistency.

Together these benefits can add value to your final drug product through optimised drug efficacy, increased shelf life, decreased time to market, and increased patient comfort. Get in touch with one of our technical experts today to discuss your formulation needs and discover how our
Super Refined ™ range can benefit you.

Super Refined™ excipients

Super Refined excipients are stripped of a number of oxidative impurities, such as peroxides, aldehydes, and catalyst residues. The removal of these problematic species helps to reduce negative API & excipient interactions, maintaining both the stability of the drug and the final formulation. In addition, the removal of these impurities can minimise cellular irritation, reduce taste impact, and potentially decrease allergenicity. 

We have a large variety of products, ranging from various polysorbates, polyethylene glycols (PEG), esters, vegetable oils, and more.
