Calcium Phosphates
The Effect of Microcrystalline Cellulose–CaHPO4 Mixtures in Different Volume Ratios on the…
Abstract
Using microcrystalline cellulose (MCC) with plastic behaviour and calcium phosphate anhydrous (CaHPO4) with brittle behaviour under compaction is very popular in the pharmaceutical industry for achieving desirable structural–mechanical properties of tablet formulations. Thus, mixtures of…

Hot-Melt Extrusion: from Theory to Application in Pharmaceutical Formulation – Where Are We…
Abstract
Hot-melt extrusion (HME) is a globally recognized, robust, effective technology that enhances the bioavailability of poorly soluble active pharmaceutical ingredients and offers an efficient continuous manufacturing process. The twin-screw extruder (TSE) offers an extremely resourceful…

Hydroxyapatite and pore former effects on the microstructure and mechanical strength of porous…
Porous hydroxyapatite (HAP) pellets were prepared by extrusion/spheronization/sintering and loaded with Lactobacillus (La-5). Micronized (PFm) or coarse size (PFc) microcrystalline cellulose were the pore formers, while HAP grades from Budenheim (Tri-cafos®) and Sigma-Aldrich with different specific…

Characterizing a design space for a twin-screw wet granulation process: A case study of…
Abstract
Twin-screw wet granulation is an emerging continuous manufacturing technology for solid oral dosage forms. This technology has been successfully employed for the commercial manufacture of immediate-released tablets. However, the higher polymer content in extended-release (ER) formulations…

Pre and post characterization of ODTs with emphasis on compression force and quality of…
Oral dispersible tablets (ODTs) are patient compliant dosage forms which rapidly disintegrate in the mouth following active absorption with rapid onset of action. The current study was designed to resolve compression problems used for ODTs, as high compression force exhibited hardness and drug…
