Description

HPMC (Hypromellose) is a hydrophilic, non-ionic cellulose ether used to form swellable-soluble matrices.

In Vitro

Hypromellose provides the release of a drug in a controlled manner, effectively increasing the duration of release of a drug to prolong its therapeutic effect[1]. Hypromellose (hydroxypropylmethylcellulose) has been used in sustained-release pharmaceutical products for many years. When used in matrix tablets, these polymers hydrate on contact with water to produce a viscous gel barrier within and surrounding the tablet. The properties of hypromellose that affect the rate of drug release include the rate of diffusion of water into the dry polymer, the rate of hypromellose hydration and gel formation, the viscosity of the hydrated hypromellose and rate of hypromellose gel erosion[2].

In Vivo

Punctal occlusion using hypromellose 2% is a low-cost and safe additional treatment for dry eye. Fluorescein and rose bengal staining tests show that there was a significant reduction in signs after occlusion using hypromellose[3]. Hypromellose is effective in improving the blood glucose metabolism and suppressing oxidative stress in mice fed with a high fat diet. The antihyperglycemic and antioxidative effects of hypromellose could be partly attributed to the regulation of hepatic glucose-regulating enzyme activities and activation of the hepatic and erythrocyte antioxidant enzymes. Hypromellose may be useful as biomaterials in the development of functional food or as therapeutic agents against high fat-induced hyperglycemia and oxidative stress[4].

In Vivo:

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
