Description

Hydroxypropylmethylcellulose acetate succinate (HPMCAS) is a cellulose derivative that combines the properties of hydroxypropylmethylcellulose (HPMC), cellulose acetate (CA), and succinic acid. It is synthesized by reacting cellulose with hydroxypropyl groups, methyl groups, acetyl groups, and succinyl groups. HPMCAS is commonly used as a pharmaceutical excipient, particularly in solid dosage forms like tablets and capsules. It functions as a binder, film former, and controlled-release agent. Its properties are highly dependent on the degree of substitution of each functional group. The presence of acetyl groups enhances its film-forming capabilities, while the succinyl groups contribute to its water solubility. HPMCAS is studied for its potential to improve drug delivery, enhance bioavailability, and provide sustained release profiles. It is also considered a safe and effective excipient, making it a preferred choice in the pharmaceutical industry. Its versatility and ability to modulate drug release profiles have prompted extensive research on its application in various drug formulations.'
