Pharmaceutical Applications of Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl Methylcellulose (HPMC) is a versatile compound that finds numerous applications in the pharmaceutical industry. This article will explore the various pharmaceutical applications of HPMC and shed light on its importance in the field.

One of the primary uses of HPMC in pharmaceuticals is as a binder. Binders are essential in tablet manufacturing as they help hold the ingredients together and ensure the tablet’s structural integrity. HPMC acts as an excellent binder due to its adhesive properties, allowing it to form a strong bond between the active ingredients and excipients.

In addition to its binding properties, HPMC also serves as a film-forming agent. This means that it can be used to create a thin, protective coating on tablets or capsules. The film coating not only enhances the tablet’s appearance but also provides a barrier that protects the active ingredients from moisture, light, and other external factors. Moreover, the film coating can also control the release of the drug, allowing for sustained or delayed release formulations.

Another important application of HPMC in pharmaceuticals is as a viscosity modifier. Viscosity refers to the thickness or resistance to flow of a liquid.
