Moisture Sorption by Polymeric Excipients Commonly Used in Amorphous Solid Dispersions and its…
Moisture sorption by polymeric carriers used for the development of amorphous solid dispersions (ASDs) plays a critical role in the physical stability of dispersed drugs since moisture may decrease glass transition temperature (Tg) and thereby increase molecular mobility of drugs leading to their…

Orally Dispersible Dosage Forms for Paediatric Use: Current Knowledge and Development of…
The paediatric population has always suffered from a lack of medicines tailored to their needs, especially in terms of accurate dosage, stability and acceptability. Orodispersible dosage forms have gone through a resurrection as an alternative to liquid formulations or fractioned solid formulations,…

Immediate release 3D printed oral dosage forms: How different polymers have been explored to reach…
Three-dimensional (3D) printing has been gaining attention as a new technological approach to obtain immediate release (IR) dosage forms. The versatility conferred by 3D printing techniques arises from the suitability of using different polymeric materials in the production of solids with different…

Targeted colonic release formulations of mesalazine – A clinical pharmaco-scintigraphic…
Colonic targeting of orally applied therapeutic drugs remains a challenge. Tablet coatings relying on gastrointestinal pH and colonic bacterial enzymes as triggers in association with an inner alkaline layer are expected to improve targeting efficiency. Mesalazine release from three differently…

Silicon Oxycarbide Porous Particles and Film Coating as Strategies for Tenofovir Controlled Release…
Sustained release of antiretroviral drugs is currently the most encouraging strategy for the prevention of the sexual transmission of HIV. Vaginal tablets based on hydrophilic gelling polymers are an interesting dosage form for this purpose, since they can be developed to modify the release of the…

Application of electrostatic dry powder coating technology on capsules to achieve sustained release
This study introduces an electrostatic dry powder coating process to coat hard gelatin capsules and hydroxypropyl methylcellulose capsules directly in a coating pan to achieve sustained release. The process overcomes many difficulties in the capsule liquid coating process, such as stickiness and…

The Use of Sodium Alginate in Extended Release Tablet Formulations
Extended release tablets are commonly based on partially synthetic cellulose ethers, such as hypromellose (HPMC), hydroxyethyl cellulose (HEC), or hydroxypropyl cellulose (HPC). Alginates offer an interesting, all-natural alternative to these polymers. The aim of the present study was to…

Enhanced Oral Bioavailability of MT-102, a New Anti-inflammatory Agent, via a Ternary Solid…
This study aimed to develop a solid dispersion (SD) of MT-102, a new anti-inflammatory agent, to improve its oral bioavailability. The ternary SD formulations of MT-102 (a poorly soluble extract of Isatis indigotica and Juglans mandshurica) were prepared using a solvent evaporation method with…
