立足高龄社会的业态创新

比起地广人稀的市场里“高大上”的美国药店，日本药店似乎更接地气，更易成为中国药店的学习效仿对象。     

特殊药品——美国药店新大陆

2006年年底，美国连锁药店协会公布了一份主题为《社区药店中的特殊药房：现在是时候了》的研究报告。报告称特殊药品市场是药店业务下一步发展的关键，因为这块市场的增长速度要远远高于传统的处方药。为了抓住这个市场机遇，报告要求药店从人员培训、店面设计等各个方面做好准备。而美国最大的连锁药店Walgreens近来也是收购了多家特殊药品运营商，力图在这一市场占领先机。     

4000家,WalgreenS的新起点

在医药零售领域，扩张也许是一个全球性的话题。在中国是这样，在美国亦如此。今年3月份，美国最大的连锁药店Walgreens公司新开了其第4000家药店，整个扩张发展进入了一个新阶段，同时公司领导层还放言开到10000家也没问题。自从上个世纪60年代美国社会向大众消费时代迈进以来，这种大规模扩张已经持续了40来年。从这个角度出发，我们可以说中国连锁药店扩张才刚刚起步。     

美国连锁药店协会

美国连锁药店协会NationalAssociation of Chain Drug Stores(NACDS)成立于1933年。它是代表美国药店业的主流——社区连锁药店的组织。 大多数美国人把连锁药店看作社区保健中心。绝大多数人在自己住所5英里范围内就可找到一家社区药店,而更有甚者则与药店毗邻而居。 这样,社区药店的药师就理所当然地成为本区惟一最受公众欢迎的保健专家了。

Safety assessment of poloxamers 101, 105, 108, 122, 123, 124, 181, 182, 183, 184, 185, 188, 212, 215, 217, 231, 234, 235, 237, 238, 282, 284, 288, 331, 333, 334, 335, 338, 401, 402, 403, and 407, poloxamer 105 benzoate, and poloxamer 182 dibenzoate as used in cosmetics

Poloxamers are polyoxyethlyene, polyoxypropylene block polymers. The impurities of commercial grade Poloxamer 188, as an example, include low-molecular-weight substances (aldehydes and both formic and acetic acids), as well as 1,4-dioxane and residual ethylene oxide and propylene oxide. Most Poloxamers function in cosmetics as surfactants, emulsifying agents, cleansing agents, and/or solubilizing agents, and are used in 141 cosmetic products at concentrations from 0.005% to 20%. Poloxamers injected intravenously in animals are rapidly excreted in the urine, with some accumulation in lung, liver, brain, and kidney tissue. In humans, the plasma concentration of Poloxamer 188 (given intravenously) reached a maximum at 1 h, then reached a steady state. Poloxamers generally were ineffective in wound healing, but were effective in reducing postsurgical adhesions in several test systems. Poloxamers can cause hypercholesterolemia and hypertriglyceridemia in animals, but overall, they are relatively nontoxic to animals, with LD(50) values reported from 5 to 34.6 g/kg. Short-term intravenous doses up to 4 g/kg of Poloxamer 108 produced no change in body weights, but did result in diffuse hepatocellular vacuolization, renal tubular dilation in kidneys, and dose-dependent vacuolization of epithelial cells in the proximal convoluted tubules. A short-term inhalation toxicity study of Poloxamer 101 at 97 mg/m(3) identified slight alveolitis after 2 weeks of exposure, which subsided in the 2-week postexposure observation period. A short-term dermal toxicity study of Poloxamer 184 in rabbits at doses up to 1000 mg/kg produced slight erythema and slight intradermal inflammatory response on histological examination, but no dose-dependent body weight, hematology, blood chemistry, or organ weight changes. A 6-month feeding study in rats and dogs of Poloxamer 188 at exposures up to 5% in the diet produced no adverse effects. Likewise, Poloxamer 331 (tested up to 0.5 g/kg day(-1)), Poloxamer 235 (tested up to 1.0 g/kg day(-1)), and Poloxamer 338 (at 0.2 or 1.0 g/kg day(-1)) produced no adverse effects in dogs. Poloxamer 338 (at 5.0 g/kg day(-1)) produced slight transient diarrhea in dogs. Poloxamer 188 at levels up to 7.5% in diet given to rats in a 2-year feeding study produced diarrhea at 5% and 7.5% levels, a small decrease in growth at the 7.5% level, but no change in survival. Doses up to 0.5 mg/kg day(-1) for 2 years using rats produced yellow discoloration of the serum, high serum alkaline phosphatase activity, and elevated serum glutamicpyruvic transaminase and glutamic-oxalacetic transaminase activities. Poloxamers are minimal ocular irritants, but are not dermal irritants or sensitizers in animals. Data on reproductive and developmental toxicity of Poloxamers were not found. An Ames test did not identify any mutagenic activity of Poloxamer 407, with or without metabolic activation. Several studies have suggested anticarcinogenic effects of Poloxamers. Poloxamers appear to increase the sensitivity to anticancer drugs of multidrug-resistant cancer cells. In clinical testing, Poloxamer 188 increased the hydration of feces when used in combination with a bulk laxative treatment. Compared to controls, one study of angioplasty patients receiving Poloxamer 188 found a reduced myocardial infarct size and a reduced incidence of reinfarction, with no evidence of toxicity, but two other studies found no effect. Poloxamer 188 given to patients suffering from sickle cell disease had decreased pain and decreased hospitilization, compared to controls. Clinical tests of dermal irritation and sensitization were uniformly negative. The Cosmetic Ingredient Review (CIR) Expert Panel stressed that the cosmetic industry should continue to use the necessary purification procedures to keep the levels below established limits for ethylene oxide, propylene oxide, and 1,4-dioxane. The Panel did note the absence of reproductive and developmental toxicity data, but, based on molecular weight and solubility, there should be little skin penetration and any penetration of the skin should be slow. Also, the available data demonstrate that Poloxamers that are introduced into the body via routes other than dermal exposure have a rapid clearance from the body, suggesting that there would be no risk of reproductive and/or developmental toxicity. Overall, the available data do not suggest any concern about carcinogenesis. Although there are gaps in knowledge about product use, the overall information available on the types of products in which these ingredients are used, and at what concentration, indicates a pattern of use. Based on these safety test data and the information that the manufacturing process can be controlled to limit unwanted impurities, the Panel concluded that these Poloxamers are safe as used.

Arformoterol: (R,R)-eformoterol, (R,R)-formoterol, arformoterol tartrate, eformoterol-sepracor, formoterol-sepracor, R,R-eformoterol, R,R-formoterol

Sepracor in the US is developing arformoterol [R,R-formoterol], a single isomer form of the beta(2)-adrenoceptor agonist formoterol [eformoterol]. This isomer contains two chiral centres and is being developed as an inhaled preparation for the treatment of respiratory disorders. Sepracor believes that arformoterol has the potential to be a once-daily therapy with a rapid onset of action and a duration of effect exceeding 12 hours. In 1995, Sepracor acquired New England Pharmaceuticals, a manufacturer of metered-dose and dry powder inhalers, for the purpose of preparing formulations of levosalbutamol and arformoterol. Phase II dose-ranging clinical studies of arformoterol as a longer-acting, complementary bronchodilator were completed successfully in the fourth quarter of 2000. Phase III trials of arformoterol began in September 2001. The indications for the drug appeared to be asthma and chronic obstructive pulmonary disease (COPD). However, an update of the pharmaceutical product information on the Sepracor website in September 2003 listed COPD maintenance therapy as the only indication for arformoterol. In October 2002, Sepracor stated that two pivotal phase III studies were ongoing in 1600 patients. Sepracor estimates that its NDA submission for arformoterol, which is projected for the first half of 2004, will include approximately 3000 adult subjects. Sepracor stated in July 2003 that it had completed more than 100 preclinical studies and initiated or completed 15 clinical studies for arformoterol inhalation solution for the treatment of bronchospasm in patients with COPD. In addition, Sepracor stated that the two pivotal phase III studies in 1600 patients were still progressing. In 1995, European patents were granted to Sepracor for the use of arformoterol in the treatment of asthma, and the US patent application was pending.     

Oral Presentations (LDD, LPES, LNM, LPAT, LNT, LPPT, LPM)

Probiotic microorganisms have been shown to provide specific health benefits when consumed as food supplements or as food components. The main problem of such products is the poor survival of the probiotic bacteria in the low pH of gastric fluid. However the use of synthetic excipients for enteric coating to prevent the exposure of microorganisms to gastric fluid is limited in food supplementary industry. Therefore the aim of this study was to develop an enteric coating formulation containing shellac as a natural polymer. Shellac possesses good resistance to gastric juice; the major disadvantage of this polymer is its low solubility in the intestinal fluid [1, 2]. Thus films containing different ratios of shellac and water-soluble polymers (sodium alginate, hydroxypropyl methylcellulose (HPMC) and polyvinylpyrrolidon (PVP)) or plasticizers (glycerol and glyceryl triacetate (GTA)) were prepared in order to analyse the films’ melting temperatures (T_m), the changes in enthalpy (ΔH), their capability of taking up water, and their solubility in different media. The release characteristics of the films were studied by loading pellets with Enterococcus faecium M74 and coating them with formulations containing different amounts of shellac and polymer or plasticized shellac. Using dissolution tests, performed according to USP XXXI paddle method, the resistance of the coatings to simulated gastric fluid (SGF, pH 1.2) and the release of cells in simulated intestinal fluid (SIF, pH 6.8) was investigated.The trials showed that an increasing amount of plasticizer results in a decrease of T_m and ΔH of the films whereat glycerol had a superior plasticization effect to GTA. The compatibility of films made of water-soluble polymers and shellac was also concentration dependent. HPMC and PVP showed superior compatibility with shellac compared to sodium alginate, since films containing shellac and more than 10% [w/w] sodium alginate tended to separate into two phases. In the end five formulations containing shellac and either 5% [w/w] glycerol, 10% [w/w] PVP, 20% [w/w] PVP, 10% [w/w] HPMC, or 5% [w/w] sodium alginate emerged as feasible for enteric coating purposes.
