The high viscosity of HPMC 60SH-50 also contributes to the controlled release of the active ingredients. The thick film formed by HPMC 60SH-50 slows down the diffusion of water into the tablet, which in turn slows down the release of the active ingredients. This controlled release is particularly important for drugs that have a narrow therapeutic window or that need to be released at a specific rate to achieve the desired therapeutic effect.
In addition to its improved film formation properties, HPMC 60SH-50 is also highly compatible with other excipients commonly used in multi-layered tablet coatings. It can be easily mixed with other polymers, such as PVA or EC, to achieve the desired film properties. This compatibility allows for the formulation of coatings with tailored properties, such as increased flexibility or improved drug release profiles.
In conclusion, HPMC 60SH-50 is a widely used film-forming agent in multi-layered tablet coatings due to its improved film formation properties. Its ability to form a strong and flexible film that adheres well to the tablet surface ensures the protection of the active ingredients throughout the shelf life of the product. Additionally, its high viscosity allows for the formation of a thicker film, which provides an additional layer of protection and contributes to the controlled release of the active ingredients. The compatibility of HPMC 60SH-50 with other excipients further enhances its versatility in the formulation of multi-layered tablet coatings. Overall, HPMC 60SH-50 is an essential component in the development of high-quality and effective multi-layered tablet coatings.
