A thorough analysis of the effect of surfactant/s on the solubility and pharmacokinetics of (S)-zaltoprofen

引用

Asian Journal of Pharmaceutical Sciences 2019年第4期14卷 435-444页

作者： Cuong Viet Pham Jong-Suep Baek Jong-Hun Park Sang-Hun jung Jong-Seong Kang Cheong-weon Cho College of Pharmacy and Institute of Drug Research and Development Chungnam National UniversityDaejeon 34134Republic of Korea Department of Herbology College of Korean MedicineDongguk UniversityGyeongju 38066Republic of Korea

Until now, there are no publications about the preformulation studies on(S)-zaltoprofen((S)-ZPF). Hence, we first investigated the solubility of(S)-ZPF, screened solubilizers and performed the pharmacokinetic study of(S)-ZPF in the presence of the solubilizers. The measurement of the solubility of(S)-ZPF in 26 different solvents was carried out, including d-alpha tocopheryl polyethylene glycol 1000 succinate(TPGS), 2-hydroxypropyl-β-cyclodextrin(HPCD), and mixtures of individual solvent. The plasma concentration of(S)-ZPF and the amount of(S)-ZPF retained in stomach were determined after oral(35.0 mg/kg) and intravenous(5.0 mg/kg) administration. The solubility of(S)-ZPF showed an increase of 484-fold in TPGS compared to its aqueous solubility. There was a significant increase of AUC 0-24 h for pure(S)-ZPF in the TPGS group(813.59 ± 64.17 μg h/ml) in comparison with AUC 0-24 h in the HPCD group(595.57 ± 71.76 μg h/ml) and water group(465.57 ± 90.89 μg h/ml). In addition, the T max of(S)-ZPF in the TPGS group was 2 h, much faster than that in the HPCD or water groups(5.50 or 5.67 h, respectively). This suggested that TPGS played a significant role in the increase of solubility and bioavailability of(S)-ZPF.

Predicting human lifespan limits

引用

Natural Science 2010年第9期2卷 984-989页

作者： Byung Mook weon jung Ho Je 不详

Recent discoveries show steady improvements in life expectancy during modern decades. Does this support that humans continue to live longer in future? We recently put forward the maximum survival tendency, as found in survival curves of industrialized countries, which is described by extended Weibull model with agedependent stretched exponent. The maximum survival ten dency suggests that human survival dynamics may possess its intrinsic limit, beyond which survival is inevitably forbidden. Based on such tendency, we develop the model and explore the patterns in the maximum lifespan limits from industrialized countries during recent three decades. This analysis strategy is simple and useful to interpret the complicated human survival dynamics.

心肌损伤通常在经皮冠状动脉介入治疗(PCI)过程中出现,并且损伤可以通过对心肌酶的测试使之容易被监控。众所周知,尼可地尔是三磷酸腺苷ATP-敏感的K+通道的开启器,通过减小作用电位从而具有抗心律失常效应和保护心脏作用。比如,通过松弛血管平滑肌以减少微冠状动脉血流阻力。研究尼可地尔的心肌保护作用,IONA研究(尼可地尔对心绞痛的作用)即大规模对稳定型心绞痛进行的研究表明,尼可地尔口服给药能够减少冠心病致死率和非致命型心肌梗塞或胸痛意外住院治疗。目前已经对数个不稳定心绞痛(UAP)或急性心肌梗塞病人进行了尼可地尔心脏保护效应的研究评估,但还没有进行大规模研究。此研究的目的在于通过对经尼可地尔注射并PCI治疗12~48h后的不稳定心绞痛患者的心肌酶进行评估来预期考察尼可地尔的心脏保护作用。
