At the age of 70 I am pleased (not proud) with my physical and mental fitness, and had never experienced a digestive problem untill my recent experience with HPMC or E464. As an adhesive, the use of HPMC in plasters, gypsum, putty powder or other building materials can improve their spreadability and prolong their operable time. Over the last few decades, there has been a growing interest in the use of three-dimensional (3D) printing technology within the medical and pharmaceutical fields to fabricate the customizable solid dosage forms that suit different needs, preferences and individual characteristics of each patient [1]. In general, tablets can be coated using either a fluid-bed dryer or air suspension coating. Statistical analysis was performed using SPSS software version 16.0 (SPSS, Inc., Chicago, IL, USA). Moreover, the use of HPMC, which is a hydrophilic polymer, can further be advantageous in terms of enhancing the solubility and dissolution of poorly water-soluble drugs in the manufacture of solid dispersion. As observed in the figure, all the HPMC dispersions exhibited a non-Newtonian (shear-thinning) pseudoplastic behavior since their viscosity values decreased as well as shear stress increased when the shear rate increased from 0 to 100 s1.

Moreover, phenytoin ODF can be used for dysphasic and schizophrenic patients and can be taken without water due to their ability to disintegrate within a few minutes to release medication in the mouth. Due to the hydrogen-bonding capabilities of plasticizers (e.g., glycerin and propylene glycol), the addition of suitable amounts of plasticizers can improve the flexibility of films by allowing the interaction of hydrogen bonding between polymer chain functional groups and the plasticizing agent, resulting in the reduction of polymerpolymer interaction [25]. Furthermore, the power-law model was fitted to the obtained results (shear stressshear rate flow curves), and the power-law model parameters (flow behavior index (n) and consistency coefficient) are shown in Table 2. Some considerations when adding HPMC to food products include:1, 3, Methods of incorporating of HPMC/CMC mixtures in food products:3, HPMC is permitted for its direct addition to food products by the FDA.4.
