- Hydroxypropyl methyl cellulose (HPMC) is a widely used pharmaceutical excipient that has been employed in various drug formulations due to its excellent film-forming properties, stability, and compatibility with other ingredients. However, like many substances, HPMC may also present side effects that could impact the safety and efficacy of the final product. This article will explore some of the potential side effects associated with HPMC and discuss their implications for pharmaceutical formulations.
- One of the most significant advantages of HPMC is its ability to form hydrogels. Hydrogels are three-dimensional networks that can absorb and retain large amounts of water or other aqueous solutions. This property makes HPMC an ideal thickening agent in food, cosmetics, and pharmaceuticals. By adjusting the degree of substitution (DS), which refers to the number of hydroxyl groups in cellulose that have been replaced by hydroxypropyl or methyl groups, the viscosity and gel formation properties of HPMC can be tailored to suit specific applications.
