Topical delivery systems containing clotrimazole for the management of candidiasis: effect of…
WHO classified Candida albicans as one of the four critical priority fungi for public health worldwide in 2022. Conventional topical formulations commercially available for the treatment of cutaneous candidiasis are associated with low drug bioavailability at the infection site and the lack of a…

Development and evaluation of febuxostat solid dispersion through screening method
Febuxostat (Febux) is a BCS II drug and has a very low solubility. In order to overcome this shortcoming, the purpose of study is to increase the in vitro dissolution (%) and drug release (%) of Febux by using a screening method. The Febux-SD formulation was prepared by screening solubilizers, pH…

A tabletability change classification system in supporting the tablet formulation design via the…
In this paper, the material library approach was used to uncover the pattern of tabletability change and related risk for tablet formulation design under the roll compaction and dry granulation (RCDG) process. 31 materials were fully characterized using 18 physical parameters and 9 compression…

Protein corona formation on lipidic nanocapsules: Influence of the interfacial PEG repartition
The parameters currently used for characterization of nanoparticles, such as size and zeta potential, were not able to reflect the performance of a nanocarrier in the biological environment. Therefore, more thorough in vitro characterization is required to predict their behavior in vivo, where…

Development and Characterization of Pentaerythritol-EudragitRS100 Co-processed Excipients as Solid…
Abstract
Atorvastatin (ATV), a lipid-lowering agent, has low oral bioavailability due to its poor water solubility, permeability, and low dissolution rate. Therefore, pentaerythritol-EudragitRS100 co-processed excipients (PECE) were synthesized, and their feasibility as solid dispersion carriers…

Exploring the use of modified in vitro digestion assays for the evaluation of ritonavir loaded solid…
Solid lipid-based formulations (sLBFs) have the potential to increase the oral bioavailability of drugs with poor solubility in water, while counteracting some of the disadvantages of liquid LBFs. The most common experimental set-up to study the performance of LBFs in vitro is the lipolysis assay,…

Personalizing oral delivery of nanoformed piroxicam by semi-solid extrusion 3D printing
Semi-solid extrusion (SSE) 3D printing enables flexible designs and dose sizes to be printed on demand and is a suitable tool for fabricating personalized dosage forms. Controlled Expansion of Supercritical Solution (CESS®) is a particle size reduction technology, and it produces particles of a pure…

Development of a Discriminative Dissolution Method, Using In-Silico Tool for Hydrochlorothiazide and…
Hydrochlorothiazide (HTZ) and Valsartan (VAL) are poorly soluble drugs in BCS classes IV and II. This study aimed to develop a method to assess the dissolution profile of tablets containing HTZ (12.5 mg) and VAL (160 mg) as a fixed-dose combination, using in silico tools to evaluate products…
