HPMC 90sh is an ideal choice for film coating due to its excellent film-forming properties and compatibility with a wide range of active pharmaceutical ingredients.
Another important application of HPMC 90sh in the pharmaceutical industry is as a sustained-release agent. Sustained-release formulations are designed to release the drug slowly and continuously over an extended period of time, providing a controlled release of the medication. HPMC 90sh is particularly well-suited for this purpose due to its ability to form a gel layer when hydrated. This gel layer acts as a barrier, controlling the release of the drug from the dosage form. By adjusting the concentration of HPMC 90sh in the formulation, the release rate of the drug can be tailored to meet the specific needs of the patient.
Furthermore, HPMC 90sh is also used as a thickening agent in liquid and semi-solid formulations. It imparts viscosity to the formulation, improving its stability and ease of administration. This is particularly important in suspensions and gels, where the drug particles or active ingredients need to be uniformly dispersed throughout the formulation. HPMC 90sh helps prevent settling of particles and provides a smooth and consistent texture to the formulation.
In conclusion, HPMC 90sh plays a crucial role in the pharmaceutical industry, with a wide range of applications in various dosage forms. Its binding, film-forming, sustained-release, and thickening properties make it an ideal choice for pharmaceutical formulations.
