HPMC as a Versatile Excipient in Oral Drug Formulations
Hydroxypropyl methylcellulose (HPMC) is a versatile excipient commonly used in oral drug formulations. It is a semi-synthetic polymer derived from cellulose and is widely recognized for its excellent film-forming and thickening properties. HPMC is also known for its biocompatibility, stability, and low toxicity, making it a popular choice for pharmaceutical applications.
One of the key applications of HPMC in oral drug formulations is as a binder. Binders are essential in tablet manufacturing as they help hold the active pharmaceutical ingredient (API) and other excipients together. HPMC acts as an effective binder by forming a strong bond between the particles, resulting in a cohesive tablet that is easy to handle and swallow. Additionally, HPMC can improve the mechanical strength of tablets, reducing the risk of breakage during handling and transportation.
In addition to its binding properties, HPMC is also used as a disintegrant in oral drug formulations. Disintegrants are added to tablets to promote their rapid breakdown and release of the API in the gastrointestinal tract. HPMC swells in the presence of water, creating channels within the tablet that allow for rapid disintegration. This helps ensure that the API is released quickly and efficiently, leading to improved drug absorption and bioavailability.
Furthermore, HPMC is commonly used as a film-forming agent in oral drug formulations.
