The pharmaceutical industry constantly seeks to improve drug delivery systems, aiming for enhanced efficacy, patient compliance, and safety. Pharmaceutical coatings play a pivotal role in this, and the selection of appropriate excipients is critical. Triethyl Citrate (TEC), a bio-based ester of citric acid, has emerged as a valuable ingredient, particularly for its function as a plasticizer in various coating formulations. NINGBO INNO PHARMCHEM CO., LTD. explores the significant contributions of Triethyl Citrate in pharmaceutical applications.

With its CAS number 77-93-0, Triethyl Citrate is recognized for its role in plasticizing polymers used in pharmaceutical coatings. These coatings are applied to tablets, capsules, beads, and granules to achieve specific release profiles, such as immediate release, sustained-release, and enteric formulations. As a plasticizer, TEC works by increasing the flexibility and reducing the brittleness of the polymer film. This is essential for preventing the coating from cracking or breaking during the manufacturing process, handling, or even upon ingestion.

The primary function of Triethyl Citrate in pharmaceutical coatings is to lower the glass transition temperature (Tg) of the film-forming polymers. This makes the film more pliable and less prone to cracking, which is especially important for enteric coatings that need to remain intact in the stomach's acidic environment but dissolve in the intestines. By ensuring the integrity of the coating, Triethyl Citrate helps guarantee that the drug is released at the intended site in the gastrointestinal tract, thereby optimizing therapeutic outcomes.

Manufacturers looking to source Triethyl Citrate for pharmaceutical use will find that its properties align well with stringent industry requirements. Its low toxicity and bio-based origin are significant advantages, contributing to the overall safety profile of the final drug product. The ability to buy Triethyl Citrate from a reliable supplier like NINGBO INNO PHARMCHEM CO., LTD. ensures consistent quality and compliance with regulatory standards.

Furthermore, Triethyl Citrate can contribute to taste masking and improving the palatability of certain medications, indirectly enhancing patient compliance, especially among pediatric populations. Its compatibility with a range of commonly used coating polymers, such as cellulose derivatives and acrylic polymers, makes it a versatile choice for formulation scientists. The compound’s use as a plasticizer in pharmaceutical coatings is a testament to its efficacy and its growing importance in modern drug development.

NINGBO INNO PHARMCHEM CO., LTD. is dedicated to providing high-purity Triethyl Citrate that meets the exacting standards of the pharmaceutical industry. By understanding the critical role Triethyl Citrate plays in improving drug delivery systems, pharmaceutical companies can leverage this versatile ingredient to develop more effective and patient-friendly medications.
