  • The general chemical structure of MHEC is presented in Fig. 2. According to supplier information, the sample employed in the study exhibited a degree of substitution relative to methylation (DS value) of 1.81, and a molar degree of substitution relative to hydroxyethylation (MS) of 0.15. Gel permeation chromatography (GPC) analysis produced molar masses of 2.48·105 g/mol (Mw) and of 1.74·105 g/mol (Mn), respectively (Table 2). Using the GPC method, a hydrodynamic radius Rh(z) of 31.0 nm and a

  • Hydroxypropyl methylcellulose, commonly known as HPMC, is a semi-synthetic polymer derived from cellulose. It serves as a multifunctional excipient due to its excellent film-forming ability, high viscosity, and pH stability. In solid dosage forms, HPMC acts as a binder, ensuring the cohesion of powders into tablets. Its thermal gelation property also makes it an ideal candidate for sustained-release matrix tablets, where it controls the release of active ingredients by forming a viscous gel layer that slows down drug dissolution.
