A conflict of interest (COI) is a conflict between private interests and one's official responsibilities. COI is unavoidable and thus needs to be managed. Debates about COI in medical research area began in the United States in the 1980s. COI clause was added to the Helsinki Declaration in the year of 2000 after the Gelsinger affair. Discussions in Japan subsequently followed, and COI management guidelines have been sequentially presented by different organizations, particularly after the Diovan incident in 2013...

To improve the dissolution and oral bioavailability of valsartan (VST), we previously formulated a supersaturable self-microemulsifying drug delivery system (SuSMED) composed of Capmul® MCM (oil), Tween® 80 (surfactant), Transcutol® P (cosurfactant), and Poloxamer 407 (precipitation inhibitor) but encountered a stability problem (Transcutol® P-induced weight loss in storage) after solidification. In the present study, replacing Transcutol® P with Gelucire® 44/14 resulted in a novel SuSMED formulation, wherein the total amount of surfactant/cosurfactant was less than that of the previous formulation...

The objective of this study was to investigate the effect of the physiological parameters (pH, buffer capacity, and ionic strength) of the gastrointestinal (GI) fluid on the dissolution behavior of the class II weakly acidic (BCS class IIa) drug valsartan. A series of in vitro dissolution studies was carried out on Diovan® immediate release tablets using media that cover the physiological range of pH (1.2 - 7.8), buffer capacity (0 - 0.047 M/ΔpH) , and ionic strength (0 - 0.4 mol/L) of the GI fluid during fasted and fed states using the conventional USP II apparatus...

The objective of this study was to investigate the transfer behavior of the weakly acidic BCS class II drug valsartan from the stomach to the small intestine during fasted and fed states. An in vitro transfer model previously introduced by Kostewicz et al. (J Pharm Pharmacol 56(1):43-51, 2004) based on a syringe pump and a USP paddle apparatus was used to determine the concentration profiles of valsartan in the small intestine. Donor phases of simulated gastric fluid during fasted (FaSSGF) and fed (FeSSGF) states were used to predisperse Diovan® tablets (160 mg valsartan)...

In order to improve the dissolution and oral bioavailability of valsartan (VST), and reduce the required volume for treatment, we previously formulated a supersaturable self-microemulsifying drug delivery system (SuSMEDDS) composed of VST (80 mg), Capmul® MCM (13.2 mg), Tween® 80 (59.2 mg), Transcutol® P (59.2 mg), and Poloxamer 407 (13.2 mg). In the present study, by using Florite® PS-10 (119.1 mg) and Vivapur® 105 (105.6 mg) as solid carriers, VST-loaded solidified SuSMEDDS (S-SuSMEDDS) granules were successfully developed, which possessed good flow properties and rapid drug dissolution...

The aim was to improve the oral bioavailability and antihypertensive activity of poorly soluble drug valsartan (VAL) by modifying the design and delivery of mesoporous silica nanoparticles (MSNs). The synthesized MSNs were functionalized with aminopropyl groups (AP-MSN) through postsynthesis and coated with pH sensitive polymer Eudragit L100-55 (AP-MSN-L100-55) for pH dependant sustain release of anionic VAL. MSNs were characterized by Brauner-Emmett-Teller (BET) surface area analyzer, zeta sizer, Field Emission Scanning Electron Microscope (FESEM), Powder X-Ray Diffraction (PXRD) and Differential Scanning Calorimetry (DSC)...

Valsartan, an angiotensin II receptor antagonist, is widely used to treat high blood pressure in the clinical setting. However, its poor water solubility results in the low oral bioavailability. The aim of this study was to improve dissolution rate and oral bioavailability by developing a self-nanoemulsifying drug delivery system. Saturation solubility of valsartan in various oils, surfactants, and cosurfactants was investigated, and the optimized formulation was determined by central composite design-response surface methodology...

Since a concept of Evidence-based Medicine appeared in medical field in 1991, modern medical treatment have been remarkably changed.However, delusive belief of EBM without criticism has brought negative aspect, such as utilization of EBM by companies as a tool of promotion of drug or medical device.Although most of clinical trials were financially supported by drug companies. result of clinical trial does not always ended in favor of test drug or device. When negative results appeared, various way were taken by industry such as usage of SPIN, emphasizing secondary endpoint...

The number of clinical research by clinical cancer study groups has been decreasing this year in Japan. They say the reason is the abolition of donations to the groups from the pharmaceutical companies after the Diovan scandal. But I suppose fundamental problem is that government-supported large-scale clinical cancer study system for evidence based medicine (EBM) has not been fully established. An urgent establishment of the system based on the national strategy is needed for the cancer patients and the public health promotion...

The objective was to improve the dissolution of valsartan by developing valsartan nanocrystals and design a pulsed release system for the chronotherapy of hypertension. Valsartan nanocrystals were prepared by sonication-anti-solvent precipitation method and lyophilized to obtain dry powder. Nanocrystals were directly compressed to minitablets and coated to achieve pulsatile valsartan release. Pharmacokinetic profiles of optimized and commercial formulations were compared in rabbit model. The mean particle size and PDI of the optimized nanocrystal batch V4 was reported as 211 nm and 0...

Paraganglioma, also termed extra-adrenal pheochromocytoma, may be observed at the base of the skull and neck as well as within the mediastinum and periaortic region. The clinical symptoms of paraganglioma of the urinary bladder include intermittent hypertensive attacks, micturition, headaches and palpitations due to high catecholamine levels; these types of paragangliomas are extremely rare. However, certain bladder paragangliomas do not present with any of these symptoms; thus, surgeons are not pre-warned on how to prepare for their resection...

Available tablets or capsules for adults are often used to prepare extemporaneously formulated medicines appropriate for children. The most acceptable drug forms in pediatric population are oral liquids and pharmacists use commercial dispersing media to compound syrups from an active substance or from tablets available on the market. In many countries ready-to-use dispersing media are not available or refunded, but pharmacists can use other compounded media, providing their compatibility and stability are proven...

When Joseph Jimenez joined Novartis, in 2007, the company was facing a big challenge: Its blockbuster drug Diovan, which accounted for more than 20% of the pharmaceutical division's revenue, would lose its U.S. patent in 2012. His senior executives had some ideas for offsetting the loss-about 100 of them. From that list they chose three on which to focus: (1) The division invested significantly in testing Afinitor (a treatment for renal cell carcinoma that was nearly ready for market) in breast cancer. (2) It set up Novartis China Commercial University to screen, hire, and train several hundred salespeople for rapid expansion in high-growth markets...
