Cellulose is a type of dietary fiber that helps regulate bowel movements and contributes to overall gastrointestinal health. It also helps to promote a feeling of fullness, which can aid in weight management and prevent overeating.

The concept of graded cellulose hinges on the principle of gradually changing the composition or structure of the cellulose fibers. This variation can be achieved through different means such as altering the density, crystallinity, or chemical functionalization along the length of the cellulose fibers. Such a tailored approach results in materials with gradient properties that can mimic the complex functionalities found in natural structures like wood or bone.

In the realm of solid dosage forms, HPMC acts as a crucial component in controlled-release matrices. Tablets containing HPMC can be engineered to release active pharmaceutical ingredients gradually over an extended period, maintaining therapeutic levels of medication in the body and reducing the need for frequent dosing. The rate of drug release from these matrices is influenced by factors such as HPMC viscosity grade, the ratio of hydroxypropyl to methyl substitution, and the manufacturing process.
