A moderate drug permeating rate (flux) is desirable for long-acting transdermal patches. In this work, a novel simple method of controlling bisoprolol (BSP) flux by ion-pair strategy was initiated. Different ion-pair complexes including bisoprolol maleate (BSP-M), bisoprolol tartarate, bisoprolol besilate, and bisoprolol fumarate were prepared and their(More)
Recommendation systems represent a popular research area with a variety of applications. Such systems provide personalized services to the user and help address the problem of information overload. Traditional recommendation methods such as collaborative filtering suffer from low accuracy because of data sparseness though. We propose a novel recommendation(More)
The aim of this work was to investigate the effect of the stability of hydrogen-bonded ion pairs with organic amines on transdermal penetration of teriflunomide (TEF). Five organic amines, diethylamine (DEtA), triethylamine (TEtA), diethanolamine (DEA), triethanolamine (TEA), and N-(2'-hydroxyethanol)-piperdine (NP), were chosen to form ion pairs with TEF(More)
OBJECTIVES The study aimed to prepare a transdermal patch for flurbiprofen using isopulegol decanoate (ISO-C10) as a permeation enhancer, and to evaluate the in-vitro and in-vivo percutaneous permeation of the drug, as well as the pharmacodynamic efficacy of the formulation. METHODS The permeation experiments were conducted on rabbit skin, and the(More)
In patches, a drug must release from patches prior to its percutaneous absorption. Chemical enhancers have been used for several decades, but their roles in drug release from patches are poorly understood. In this work, the roles of chemical enhancers in bisoprolol tartrate (BSP-T) release from patches were probed in vitro and in vivo. More importantly, an(More)
The aim of this study was to design a novel felbinac (FEL) patch with significantly higher (P < 0.05) skin permeation amount than the commercial product SELTOUCH® using ion-pair and chemical enhancer strategy, overcoming the disadvantage of the large application area of SELTOUCH®. Six complexes of FEL with organic amines diethylamine (DEA), triethylamine(More)
This paper studies the problem of high-speed train operation with special attention to minimizing the energy consumption. The performance characteristics of a high-speed train, including traction characteristic and regenerative braking, and the railway geographical conditions consisting of slope, curve, and tunnel parameters, are fully considered in the(More)
Myocardial ischemia is a pathological state of heart with reduced blood flow to heart and abnormal myocardial energy metabolism. This disease occurs commonly in middle aged and elderly people. Several studies have indicated that the rat was an appropriate animal model used to study myocardial ischemia. In this study, in order to gain insights into the(More)
Recent publications are quoted to summarize multiple use of microdialysis in medical fields, especially in pharmacology and pharmacokinetics. Microdialysis was coupled with HPLC-ECD, HPLC-MS and other detectors to study endogenous substances and medicines, including neurotransmitters, amino acid, other endogenous metabolites and drugs as well as Chinese(More)
