Common Side Effects
Uses of HPMC
Hydrophilic matrices enable the controlled release of drug via the gel layer through diffusion (soluble active ingredients) and erosion (insoluble active ingredients) – with the viscosity of the polymer having a big impact on the release profile. HPMC allows pharma companies to modify the release profiles of their drugs using matrix tablet technology, providing more effective dosing and better patient compliance through reduced tablet burden. After all, once-a-day medicine is better than multiple tablets several times a day.
Furthermore, it acts as a film former, offering protection against environmental factors and enhancing the mechanical properties of composite materials. Its emulsifying capabilities help in stabilizing oil-in-water emulsions, making it vital in formulating paints, coatings, and personal care products.
