Live bacterial cells (LBCs) are administered orally as attenuated vaccines to deliver biopharmaceutical agents and as probiotics to improve gastrointestinal (GI) health. However, LBCs present unique formulation challenges and must survive GI antimicrobial defenses including gastric acid after administration. We present a simple new formulation concept, termed polymer film laminate (PFL). LBCs a...

The purpose of the research was to present Budesonide (BUD) as a novel formulation showing improved aqueous solubility, which may decrease variability in C max⁡ and T max⁡ found in inflammatory bowel disease (IBD) patients, and drug targeting to colon. To improve aqueous solubility, solid dispersion (SD) of the BUD with poloxamer 188 was prepared by melting method. Physical characterization of ...

This study aimed to research the preparation and content determination of capsaicin-chitosan microspheres (CCMS) enteric coated tablets. The core tablets were prepared with the method of wet granulation. Nine formulae were designed to determine the optimal formula of the core tablet. Eudragit L100 was used to prepare the CCMS enteric-coated tablets. The effect of enteric coated formulation vari...

Objective: The present work was to formulate buoyant system in order to protect the drug from gastric acid degradation, increasing the gastric residence time, control the drug leaching by use of enteric polymers, prolong the half life for longer duration of action, furthermore to prevent dosage form adherence to the mucous wall in order to avoid incomplete drug release. Moreover the side effect...

The purpose of this study was to use polyethylene glycol as a carrier to improve the solubility of an aqueous insoluble drug by melting and molding method. The release of dissolved drug was designed to be subsequently sustained with an addition of xanthan gum. The release of indomethacin from the developed system into phosphate buffer pH 6.2 was conducted using the dissolution apparatus. This c...

conclusions eudragit coated nanoparticle of chitosan is an efficient choice for oral delivery of dna to upper part of gi tract. results the mean size and zeta potential of particles were 300 ± 4 nm and 14 ± 0.5 mv, respectively. encapsulation of this system was 89.6 ± 1.2%. dna release from batches was less than 12% at ph = 5.2 and more than 60% at ph = 6.8 with significant difference of p < 0....

although economists and entrepreneurs had been aware of the impact of economies of scale on average cost, no comprehensive theory was introduced until 1950s. economies of scale is used by economist as a practical measure for evaluating the extent of competition (monopoly) in real markets. there are two primary aims of this paper: 1) to introduce theoretical aspects of economies of scale, 2) to ...

3D printing of oral solid dosage forms is a recently introduced approach for dose personalisation. Fused deposition modelling (FDM) one the promising and heavily researched techniques in pharmaceutical field. However, successful application this technique relies greatly on mass manufacturing physically chemically stable filaments, that can be readily available as shelf item to printed on-demand...
