the present study involves preparation and evaluation of gastric-mucoadhesive microparticles with metformin hydrochloride as model drug for prolongation of gastric residence time. the microparticles were prepared by the emulsification solvent evaporation technique using polymers of carbomer 934p (c) and ethylcellulose (ec). the microparticles were prepared by emulsion solvent evaporation method...

Guaifenesin, a highly water-soluble active (50 mg/mL), classified as a BCS class I drug.Owing to its poor flowability and compressibility, formulating tablets especially high-dose one,may be a challenge. Direct compression may not be feasible. Bilayer tablet technology appliedto Mucinex®, endures challenges to deliver a robust formulation. To overcome challengesinvolved in bilayer-tablet manufa...

The solid state polymerization (SSP) of PET/PC reactive extrusion blends with and without cobalt catalyst at different polymer ratios was studied. Thermal and rheological evaluations were performed. DSC results showed changes in the PET’s T g , T ch , T m and X c . The melt flow rate (MFR) decreased for PET and the blends. The intrinsic viscosity increased. The variation in calorimetric and rhe...

Powder flow is influenced by environmental factors, such as moisture and static electricity, as well as powder related factors, such as morphology, size, size distribution, density, and surface area. Pharmaceutical solids may be exposed to water during storage in an atmosphere containing water vapor, or in a dosage form consisting of materials (e.g., excipients) that contain water and are capab...

Shankha Bhasma is a popular Ayurvedic formulation which is used in hyperacidity, indigestion, ulcerative dyspepsia and other acid peptic disorders. The dosage uniformity and patient compliance can be increased and adultration can be decreased in ayurvedic powders by formulating them into tablets. The aim of the present work is to develop and evaluate Shankha Bhasma tablets using starch and acac...

This work investigates a method for pre-screening material systems selective laser sintering using combination of revolution powder analysis (RPA) and machine learning. To develop this method, nylon was mixed with alumina or carbon fibers in different wt.% to form varying flowability. The materials were measured custom RPA device the results compared as-spread layer density surface roughness. M...

Two sets of spray-drying conditions were applied on skim dromedary and cow's milks to determine the effect air outlet temperature (75 85°C) milk type proximate composition, particle-size distribution, flow properties spray-dried powders. The distribution was more influenced by chemical composition than conditions. impacted powder flowability, as basic flowability energy significantly increased ...
