Role of Hydroxypropyl Methylcellulose 464 in Enhancing Drug Stability and Bioavailability
Hydroxypropyl Methylcellulose 464, also known as HPMC 464, is a widely used pharmaceutical excipient that plays a crucial role in enhancing drug stability and bioavailability. This article aims to explore the various ways in which HPMC 464 contributes to the effectiveness of pharmaceutical formulations.
One of the primary functions of HPMC 464 is to improve the stability of drugs. Many active pharmaceutical ingredients (APIs) are prone to degradation when exposed to environmental factors such as light, heat, and moisture. HPMC 464 acts as a protective barrier, shielding the API from these detrimental elements. Its film-forming properties create a physical barrier that prevents the penetration of moisture and oxygen, thereby reducing the risk of degradation.
