Deepti Pandita, Neelam Kumari, Viney Lather
The current investigation involves the development of a thermodynamically stable and dilutable self-nanoemulsifying drug delivery system (SNEDDS) for tolbutamide, a poorly water soluble hypoglycemic drug, in order to achieve higher water solubility and enhanced dissolution rate which in turn improves its oral bioavailability. Pseudo-ternary phase diagrams suggested the suitability of oleic acid (lipid), Tween 20 (surfactant) and PEG 400 (co-surfactant) for developing the SNEEDS formulations. The optimal SNEDDS formulation having mean globule diameter, viscosity, polydispersity value of 58...

Cohesiveness and flowability of particulated food systems is of particular interest in the oral processing and swallowing of food products, especially for people suffering from dysphagia. Although cohesiveness of a bolus is an essential parameter in swallowing, a robust technique for objective measurement of cohesiveness of particulated semi- or soft-solids is still lacking. In our approach the ring shear tester is used to measure the cohesiveness and flowability of a model particulated food system based on fresh green pea powders and pastes with controlled moisture content...

The microbiota-gut-brain axis (MGBA) regulates the reciprocal interaction between chronic inflammatory bowel and psychiatric disorders. This interaction involves multiple pathways that are highly debated. We examined the behavioural, biochemical and electrophysiological alterations, as well as gut microbiota composition in a model of antibiotic-induced experimental dysbiosis. Inflammation of the small intestine was also assessed. Mice were exposed to a mixture of antimicrobials for 2weeks. Afterwards, they received Lactobacillus casei DG (LCDG) or a vehicle for up to 7days via oral gavage...

Water-soluble polymers are often used as pore formers to tailor permeability of film-forming hydrophobic polymers on coated dosage forms. However, their addition to a coating formulation could significantly increase the viscosity thus making the coating process difficult. Moreover, the dissolution of pore formers after oral administration could compromise film integrity resulting in undesirable, inconsistent release profiles. Therefore, a non-leaching, pH-responsive nanoparticulate pore former is proposed herein to preserve film integrity and maintain pH-dependent permeability...

Absorption of posaconazole oral suspension is influenced by several factors including diet, medications, and mucosal integrity. However, there are few prospective data about which is the most important modifiable factor in routine clinical practice. We prospectively analyzed clinical risk factors associated with low posaconazole trough concentrations in 114 patients receiving anticancer chemotherapy due to acute myeloid leukemia or myelodysplastic syndrome who received posaconazole oral suspension. In multivariate analyses, risk factors for drug level<500ng/mL included low calorie intake, mucositis≥grade 2, H2 blocker famotidine and proton-pump inhibitor...
