In Vitro and in Vivo Evaluation of Whole and Half Tablets of Sustained-Release Adinazolam Mesylate

The mechanism of release from sustained-release adinazolam mesylate tablets was assessed by the Higuchi equation and by analysis of drug release profiles through 60% released using the Peppas equation. Computed values of the diffusional exponent, n, ranged from 0.59 to 0.66. Values of n in this range are consistent with a mixed mechanism of release, with diffusion of drug through the hydrated polymer matrix and relaxation of this matrix being the principal processes controlling release. The rate of in vitro drug release was increased for half tablets relative to whole tablets and is attributed to an increase in the surface to volume ratio of half tablets of about 16%. This increase in surface-to-volume ratio of half tablets was reflected by an increase in the constant, k, from the Peppas equation of 20–23% and by an increase in the slope of Higuchi plots of 12–18% for four lots of tablets. In vivo/in vitro relationships from two bioavailability studies were thoroughly evaluated. Using either a linear or a quadratic relationship, an in vivo/in vitro correlation exists for sustained-release adinazolam mesylate tablets.     

新药甲磺酸帕珠沙星的手性拆分

目的：建立新药甲磺酸帕珠沙星手性拆分的方法。方法：运用AD手性柱法和流动相添加剂法，考察了不同条件下对分离的影响。结果：运用这两种方法，甲磺酸帕珠沙星都可以达到基线分离，相同条件下，柱温越低，拆分因子越大。结论：在分离甲磺酸帕珠沙星时，流动相添加剂法要优于手性柱法。     

甲磺酸帕珠沙星注射液治疗急性细菌性感染有效性和安全性的多中心临床研究

目的评价甲磺酸帕珠沙星注射液治疗急性细菌性呼吸系统、泌尿生殖系统感染的有效性、安全性。方法采用随机单盲平行对照多中心试验方法。选择急性细菌性呼吸系统、泌尿生殖系统感染患者213例，可评价病例209例，随机编人试验组或对照组。试验组101例．每日1次给予甲磺酸帕珠沙星注射液300mg，iv，gtt，bid；对照组108例，每日1次给予加替沙星注射液200mg，iv，gtt，bid。疗程7～10d。结果甲磺酸帕珠沙星组、加替沙星组有效率分别为94．06％（95／101）和90．74％（98／108）；痊愈率分别为67．33％（68／101）和70．37％（76／108）；细菌清除率分别为94．62％（88／93）和93．62％（88／94）；不良反应发生率分别为7，69％（8／104）和5．50％（6／109）。两组有效性、安全性相似（P〉0．05）。结论甲磺酸帕珠沙星注射液治疗急性细菌性呼吸系统、泌尿生殖系统感染有效、安全，与加替沙星相当。     

A long-term time course of colorimetric assessment of the effects of imatinib mesylate on skin pigmentation: a study of five patients

BACKGROUND: Imatinib mesylate (IM), the first-line treatment of chronic myeloid leukaemia (CML), is a tyrosine kinase inhibitor that targets those proteins involved in BCR-ABL signal transduction in CML, c-kit (KIT) and platelet-derived growth-factor (PDGFR) receptor. The use of IM has been associated with cutaneous reactions. In the last 2 years numerous studies have focused the attention on hypopigmentations, depigmentations and photosensitivity developing after the initiation of IM therapy. OBJECTIVE: The aim of this study is to evaluate the effects of IM therapy on the skin pigmentation of five patients affected by CML. METHODS: Skin pigmentation measurements were performed with a Minolta CR-200 Chromameter. results: All the studied patients show the gradual lightening of the skin on unexposed areas over the treatment with IM. In particular, this explorative colorimetric study indicates the association between IM and skin depigmentation with a significant increase of luminance value (L*) (P = 0.001) and a significant decrease of the pigmentation value (b*) (P = 0.028). CONCLUSION: Even if we do not know the clinical significance of the skin depigmentation caused by IM, the regulatory role of KIT and its ligand stem cell factor in melanocyte development and survival seems to suggest an objective mechanism of action for IM in the pathogenesis of this cutaneous depigmentation.     

国产加贝酯耐受性试验研究

健康成年人自愿受试者１０例，随机分为３组，分别住院静脉注射加贝酯２００ｍｇ／ｄ、３００ｍｇ／ｄ、４００ｍｇ／ｄ。结果除高浓度（３００ｍｇ加贝酯溶于５％Ｇ－Ｓ５００ｍｌ）组，在滴速６０滴／ｍｉｎ时，１例出现局部发红，疼痛及２例于停药后１周出现轻度表浅静脉炎外，未发现过敏，血压下降，ＥＣＧ改变，肝、肾功能损伤等其它不良反应，说明国产加贝酯注射剂临床应用安全，成人每ｄ可用１００～４００ｍｇ，以１００～２００ｍｇ溶于５％葡萄糖液５００ｍｌ静滴为宜，但１０例中有６例（６０％）因药液外渗，引起局部刺激症状，故应尽量避免高浓度，快速静滴，并防止液体外溢皮下。
