The oral bioavailability of therapeutic proteins is limited by the gastrointestinal barriers. Encapsulation of labile proteins into nanoparticles is a promising strategy. In order to improve the stability of nanoparticles, lyophilisation has been used to remove water molecules from the suspension.…

We have observed an interesting phenomenon in which grinding of freeze-dried monoclonal antibody X (mAb-X) formulation powder resulted to significant protein sub-visible particles (SbVPs) in the reconstituted liquid, which could only be observed by sensitive particle analytical methods such as MFI…

Freeze-drying, until now, has been a process that was designed using a trial and error experimental approach. This approach is often material and time consuming, and the resulting freeze-drying processes are neither optimum nor robust. Accordingly, the objective of this study was to develop a…

Drying of coacervates can cause various stresses which may lead to the damage of the outer layer membrane, aggregation, and poor rehydration properties. Gelatin/pectin coacervates prepared with addition of trehalose as cryoprotectant were subjected to freeze-drying. The addition of trehalose (15%)…

Intracellular/extracellular protein aggregation is linked to variety of neurodegenerative diseases. Current research focusses on identifying anti-amyloidogenic small molecules to inhibit such protein aggregation and associated cytotoxicity. We have recently demonstrated that transforming those…

The production of freeze-dried liposomes encapsulating drugs is considered a key challenge since the drugs are prone to leakage. The aim of this work was to study the effect of different saccharides on preserving the stability and drug retention capacity of a previously developed liposomal…

Fast dissolving tablets (FDTs) is one of the most widely accepted and popular dosage form, especially for paediatric and geriatric patients. Conventional solid dosage forms like tablets and capsules are facing the problems like difficulty in swallowing (dysphasia), resulting in many incidences of…

Disulfiram (DSF), an FDA-approved anti-alcoholic drug, has recently shown that it possesses anti-cancer effects. However, DSF is hydrophobic in nature with less stability. Therefore, new approaches are required for the effective delivery of DSF to treat cancers. Herein, we prepared DSF loaded soy…
