Abstract:

Baclofen, a muscle relaxant used for severe pain management, has a narrow absorption window limiting its bioavailability. Enhancing its gastric residence time could potentially improve its absorption and effectiveness. Floating drug delivery systems are a promising approach to prolong drug retention in the stomach. This study aimed to develop a floating bilayer film for the sustained release of baclofen. The core of the film was formulated with baclofen, PVP K90, sodium alginate, and PEG 400 as a plasticizer, while the controlled release layer contained Eudragit RS100 or RLPO with different pl

Abstract:

Uniaxial alignment of electrospun fibers can provide a useful approach to develop novel functional nanomaterials for applications in a wide variety of fields. In this study, a polypropylene- (PP-) coated spinneret and a metal spinneret were utilized to carry out the single-fluid electrospinning processes. A metal rod frame was utilized as the collector to steer the nanofibers. Using polyvinylpyrrolidone K90 (PVP K90) as a filament-forming polymeric model at a concentration of 9% (w/v) in ethanol, the experimental observations and results demonstrated the following results: (1) the utilization

Abstract:

The crystallization of mefenamic acid in transdermal patch is a major problem that makes the patch unstable and decreases the drug release. The additive was used to inhibit crystallization of a mefenamic acid. Among the different types of additives, polyvinylpyrrolidone (PVP) K30 and PVP K90 were studied and found to be highly effective in inhibiting the crystallization of the drug. The PVP presented as a solubilizer agent for mefenamic acid in matrix patches at the different ratio between drug : PVP, 1 : 2 and 1 : 2.5 for using PVP K30 and 1 : 1.5 and 1 : 2 for using PVP K90.

Abstract:

Dissolving microneedles are extensively applied in drug delivery systems to enhance penetration into the skin. In this study, dissolving microneedles fabricated from polyvinylpyrrolidone K90 (PVP-K90) and hydroxypropylmethyl cellulose (HPMC) E50 in different ratios were characterized. The selected formulations incorporated Oryza sativa L. extract complex and its characteristics, transfollicular penetration, and safety were observed. The microneedles, fabricated from PVP K90: HPMC E50 in a ratio of 25:5 (P25H5) and 20:10 (P20H10), revealed excellent morphological structure, proper mechanical st

Abstract:

The aim of this study was to investigate the modification of black glutinous rice starch (BGRS) as tablet filler. The black glutinous rice was treated with NaCl and NaOH to obtain BGRS. The native BGRS was modified by pregelatinizaion and prepared as co-composite and used as filler in tablet formulation compared with Starch 1500®. Propranolol was used as a model drug. The properties of tablets including disintegration time were evaluated. Interestingly, the disintegration times of the native BGRS was less than 90s which was faster than Starch 1500®. The results suggest that the native BGRS wou

Abstract:

Polyvinyl pyrrolidone (PVP) with different molecular weights was used as capping agent to synthesize silver nanowires through a polyol process. The results indicated that the yields and aspect ratios of silver nanowires were controlled by the chain length of PVP and increased with increasing the molecular weight (MW) of PVP. When the long-chain PVP-K90 (MW = 800,000) was used, the product was uniform in size and was dominated by nanowires with high aspect ratios. The growth mechanism of the nanowires was studied. It is proposed that the chemical adsorption of Ag+on the PVP chains at the initia
