Selecting the appropriate grade of Hypromellose Acetate Succinate (HPMCAS) is crucial for the successful development of pharmaceutical formulations, whether for enteric coating or solid dispersion applications. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of pharmaceutical grade HPMCAS products, each tailored to meet specific performance requirements. Understanding the key differentiating factors will help manufacturers make informed decisions to optimize their drug delivery systems.

HPMCAS grades are primarily differentiated by their particle size, pH solubility profile, and substitution levels of acetyl and succinoyl groups. For enteric coating, the pH solubility dictates the site of drug release. Grades with higher pH solubility (e.g., opening pH > 6.5) are suitable for targeting release further down the digestive tract, while those with lower pH solubility (e.g., opening pH > 5.5) release drugs closer to the stomach. NINGBO INNO PHARMCHEM CO.,LTD. provides detailed specifications for each grade, enabling precise selection based on the intended application and pharmacokinetic goals.

In solid dispersion applications, the interaction between HPMCAS and the API is key to maintaining the amorphous state. The choice of HPMCAS grade can influence the drug loading capacity, the method of preparation (e.g., spray drying, hot melt extrusion), and the physical stability of the resulting dispersion. Manufacturers looking to buy HPMCAS for solubility enhancement should consult NINGBO INNO PHARMCHEM CO.,LTD.'s technical data to identify the grade that best supports their API's properties and processing conditions.
