Freeze-drying of drug nanosuspension– study of formulation and processing factors for the…
The aim of this work was to systematically study the effect of freeze-drying of bottom-up processed cilostazol nanosuspension on the particle size after redispersion. Several different cryoprotectants and concentrations were compared and the influence of processing variables such as freezing…

Research progress of microneedles in the treatment of melanoma
Melanoma is an aggressive malignancy deriving from melanocytes, which is characterized by high tendency of metastases and mortality rate. Current therapies for melanoma, like chemotherapy, immunotherapy and targeted therapy, have the problem of systemic exposure of drugs, which will lead to many…

Simplified choice of suitable excipients within biologics formulation design using protein-protein…
Still today, high-concentration protein formulations are often developed based on high-throughput experimental screening approaches. Although likely delivering working formulations, these approaches do not lead to a deep/mechanistic understanding of the protein phase behavior in solution. Within…

Trehalose-releasing nanogels: A step toward a trehalose delivery vehicle for autophagy stimulation
Trehalose has been widely studied as a treatment for a variety of human disorders due to its ability to stimulate autophagy. Trehalose, however, is poorly adsorbed and is hydrolyzed in the intestinal mucosa, and oral delivery requires relatively high doses to induce autophagy. The parenteral…

Hydroxypropyl-β-Cyclodextrin Enhances Oral Absorption of Silymarin Nanoparticles Prepared Using…
The oral bioavailability of drugs is limited by factors such as poor membrane permeability, low solubility, and low dissolution rate. Silymarin (SLM) is a health-food active ingredient that is good for immunosuppression and tumor suppression. However, obtaining a good oral bioavailability is…

Development of Lipid-Based Gastroretentive Delivery System for Gentian Extract by Double…
Gentian (Gentiana lutea L., Gentianaceae) root extract (GRE) is used for the treatment of gastrointestinal disorders. However, its bioactive potential is limited in conventional forms due to the low bioavailability and short elimination half-life of the dominant bioactive compound, gentiopicroside.…

On the Feasibility of Spray-Dried Eudragit-Trehalose Microparticles for Enteric Drug Delivery
Enteric infections have long constituted a silent epidemic responsible for hundreds of thousands of deaths around the world every year. Because of the global rise in antibiotic-resistant bacteria and the slow development of new small-molecule antibiotics, alternatives such as bacteriophage therapy…
