Hypromellose Acetate Succinate
Hypromellose Acetate Succinate (HPMCAS) is a highly functional pharmaceutical excipient designed to meet the complex demands of modern drug formulation. Its primary roles as an enteric coating material and a carrier for solid dispersions make it invaluable for improving drug solubility and ensuring targeted delivery. With distinct pH-dependent dissolution profiles, HPMCAS offers precise control over drug release, safeguarding sensitive APIs from gastric degradation and facilitating optimal absorption in the small intestine.
- Leverage HPMCAS for effective enteric coating, ensuring targeted drug release in the duodenum to improve medicine absorption in the small intestine. This contributes to better pharmaceutical outcomes and enhanced drug efficacy.
- Utilize HPMCAS as a carrier for solid dispersion technologies, a key strategy for enhancing the solubility and bioavailability of poorly water-soluble drugs, making challenging APIs more effective.
- Benefit from HPMCAS's versatility in both aqueous and organic solvent systems for coating applications, offering flexibility in manufacturing processes and reducing environmental impact compared to some alternatives.
- Explore HPMCAS in advanced manufacturing techniques like Hot Melt Extrusion (HME) and spray drying, which are crucial for creating amorphous solid dispersions that significantly boost drug performance.
Key Advantages Offered
pH-Dependent Drug Release
Achieve precise control over drug release profiles by selecting HPMCAS grades with specific pH solubility points, allowing for targeted delivery within the gastrointestinal tract.
Enhanced Bioavailability
As a leading polymer in amorphous solid dispersion, HPMCAS significantly improves the solubility and absorption of poorly water-soluble drugs, thereby increasing their bioavailability.
Manufacturing Flexibility
The ability of HPMCAS to be processed in both aqueous and organic solvent systems provides manufacturers with greater flexibility in their formulation and production processes.
Key Applications
Enteric Coating
Protect acid-sensitive drugs from degradation in the stomach and ensure their release in the alkaline environment of the small intestine for optimal absorption.
Solid Dispersion Carrier
Formulate amorphous solid dispersions to enhance the dissolution rate and bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
Sustained and Controlled Release
Develop drug delivery systems that provide gradual and predictable release of APIs over an extended period, improving patient compliance and therapeutic efficacy.
Taste Masking
Effectively mask unpleasant tastes of certain APIs, leading to improved patient acceptance, especially for oral dosage forms.
