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…

HME as Advanced Approach for Development of Solid Self Emulsifying Drug Delivery System
The pharmaceutical industry is paying more and more attention to hot-melt extrusion (HME), but this technology's promise for creating solid self-emulsifying drug delivery systems (S-SMEDDS) has not yet been fully realized. The numerous published publications over the past five years show that hot…

Influence of refilling on dosing accuracy of loss-in-weight powder feeders in continuous…
Abstract
Continuous manufacturing is a novel concept to produce high quality drug products. The manufacture of solid dosage forms starts with the feeding of materials, which is consider a critical step because it could have a high influence on the quality of the final product. Therefore, this unit…

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…

Comparison of the liquisolid technique and co-milling for loading of a poorly soluble drug in…
Abstract
Drug loading into mesoporous carriers may help to improve the dissolution of poorly aqueous-soluble drugs. However, both preparation method and carrier properties influence loading efficiency and drug release. Accordingly, this study aimed to compare two preparation methods: formulation…

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…
