ElBakali Rachid*, Maamri Abdellatif , Smiri Youssef Team of Health and Environment, EDD Laboratory, Faculty of Science, Mohammed First University, Oujda, Morocco ABSTRAC Our health is influenced by many factors, called the determinants of health. WHO has defined its determinants as the set of "personal, social, economic and environmental factors that determine the health status of individuals or populations" (WHO, 1999). Conceptual models or theoretical frameworks help us to understand the complex issues that impede the determinants of health, support health planning interventions and policy development, and most importantly, understand the dimensions of health in order to act to reduce health inequalities between different population groups. This study examined diachronically different frameworks related to the determinants of health, classified them into forty-one conceptual frameworks developed by different countries, organizations and theorists and described as explanatory frameworks, and/or interactive frameworks, and/or action-oriented frameworks. Each framework is detailed according to the important elements and its field of interest. Five frameworks were selected after an in-depth analysis to agree on a comprehensive framework adapted to the Moroccan context and current political concerns and knowledge. In this perspective, our project proposes a conceptual framework of health determinants specific to the Moroccan context that is based on a holistic and intersectoral approach, which recognizes social inequalities in health, describes the role of individuals and communities, gives the importance of upstream action, and helps to improve our understanding of complex problems in the Moroccan health system.
摩洛哥奥吉达穆罕默德第一大学理学院EDD实验室健康与环境研究小组(ElBakali Rachid*, Maamri Abdellatif, Smiri Youssef)我们的健康受到许多因素的影响,这些因素被称为健康的决定因素。卫生组织将其决定因素定义为"决定个人或人口健康状况的一系列个人、社会、经济和环境因素"(卫生组织,1999年)。概念模型或理论框架帮助我们了解阻碍健康决定因素的复杂问题,支持卫生规划干预措施和政策制定,最重要的是,了解健康的各个方面,以便采取行动减少不同人口群体之间的健康不平等。本研究考察了与健康决定因素相关的不同框架,将其分为41个由不同国家、组织和理论家制定的概念性框架,并将其描述为解释性框架、互动框架和/或面向行动的框架。每个框架都根据重要元素及其感兴趣的领域进行了详细说明。经过深入分析,选定了五个框架,以商定一个适合摩洛哥国情和当前政治关切和知识的全面框架。从这个角度来看,我们的项目提出了一个针对摩洛哥环境的健康决定因素的概念框架,该框架基于整体和跨部门的方法,认识到健康方面的社会不平等,描述了个人和社区的作用,给出了上游行动的重要性,并有助于提高我们对摩洛哥卫生系统中复杂问题的理解。

Co-crystallization is an emerging approach for enhancing physicochemical properties like solubility, stability, bioavailability of poorly soluble drugs of BCS class II in pharmaceutical development without changing the chemical composition and considered better alternatives to optimize drug properties. Co-crystal is a crystalline entity consists of API and a stoichiometric amount of a pharmaceutically acceptable co-crystal former formed by intermolecular interactions like Hydrogen bonding, π-π stacking and Van der Waals forces. In this article, an overview of pharmaceutical cocrystals will be presented along with the intermolecular interactions (Chemistry of Co-crystals), methods of their preparations, characterization of co-crystals altered physicochemical properties. Furthermore, this article also gives a brief explanation about newer trends in co-crystals with application of co-crystals in medicines and industries. *Corresponding Author Email: shaktipalpatil@yahoo.com Received 04 April 2019, Accepted 16 April 2019 Journal home page: http://www.ajptr.com/ Patil et. al., Am. J. PharmTech Res. 2019;9(05) ISSN: 2249-3387 www.ajptr.com 2 INTRODUCTION The pharmaceutical industry encompasses wide variety of products out of which most are manufactured as solid dosage forms. Successful pharmaceutical development of a drug molecule depends not only on its potency and selectivity but also on its stability. Thus, the properties active pharmaceutical ingredients (APIs) depends on the identity of its constituents as well as on their arrangements. Many potential drugs failed due their unfavourable properties such as poor water solubility, unfavourable bioavailability, physical and chemical instability, inappropriate dissolution. It is easy to solve solubility problem of amorphous form, but difficult for crystalline drug. The precise control of molecular orientation and packing arrangement in the crystal of drug molecules can improve their solubility with no alteration in stability and biological activity. The solid APIs exist in different forms such as crystalline solids, amorphous forms, polymorphs, solvates, hydrates, salts. Many a times an API cannot be formulated in its pure form due to various issues of instability, solubility, compatibility, dissolution, etc. Thus, they are converted to solid forms such as polymorphs, salts, solvates, hydrates, amorphous and co-crystals. Improving the solubility of BCS class II drugs is currently one of the main challenges for the pharmaceutical industry for drug development. The traditional approaches for enhancing poor aqueous solubility (e.g., salt formation, micronization, solid dispersion formulations) often fail to produce a viable solid form, as the increase in dissolution rate achieved is frequently insufficient to provide adequate enhancement of bioavailability. Over the last decade, there has been growing interests in the design of pharmaceutical co-crystals, which emerges as a potential method for enhancing

PharmTech Res. 2019;9(05) ISSN: 2249-3387 3 www.ajptr.com在环境条件下”。就知识产权保护的机会和延长已建立的原料药生命周期的可能性而言,共晶方法对制药公司具有宝贵的优势。共晶与溶剂化物和水合物有什么不同?共晶常常与溶剂化物和水合物等伪多晶相混淆。共晶与溶剂化物和水合物的不同之处在于存在于其中的组分的物理状态。溶剂化物和水合物是固体药物的结晶形式,属于多组分体系。多组分系统由两个或多个固体或一个或多个固体和液体组成。溶剂化物是一种含有化学计量量或非化学计量量溶剂的晶体形式,水合物是一种以水为溶剂的溶剂化物。共晶也是一种多组分体系,但它是在两种化合物之间形成的,并且两者在环境条件下都处于固态。

P. Anusha, P. TripuraSundari Department of Pharmaceutics, RBVRR College of pharmacy Affiliated to Osmania University, Barkatpura, Hyderabad-500027, India ABSTRACT A muscle spasm, or muscle cramp, is an involuntary contraction of a muscle. Muscle spasms occur suddenly, usually resolve quickly, and are often painful. The use of NSAIDs has been routine in the management of muscle spasm. Although effective at reducing pain and inflammation. NSAIDs may not be appropriate to use frequently or longer time due to their known side effects. Natural agents like camphor and menthol are having analgesic activity as well as each active individual ingredient has its own medicinal value. For greater and effective results we are using combination of camphor and menthol. Hydrophilic and hydrophobic ointments were prepared by taking 25mg, 50mg and 100mg of each agent as combination of camphor-menthol. All the prepared formulations were evaluated for pH, spreadability and diffusion studies. The selected formulations were evaluated for In-vivo studies in comparison with marketed preparations. The finalized preparation was kept for stability studies according to ICH guidelines.
摘要:肌肉痉挛或肌肉痉挛是肌肉的不自主收缩。肌肉痉挛是突然发生的,通常很快就会消失,而且常常是疼痛的。非甾体抗炎药的使用已成为治疗肌肉痉挛的常规方法。虽然能有效减轻疼痛和炎症。由于已知的副作用,非甾体抗炎药可能不适合频繁或长时间使用。天然药物如樟脑和薄荷醇具有镇痛作用,而且每种有效成分都有其药用价值。为了取得更大更有效的效果,我们正在使用樟脑和薄荷醇的组合。分别取各药剂25mg、50mg、100mg与樟脑薄荷醇复配制成亲疏水软膏。对所有制备的配方进行了pH、展布性和扩散研究。选定的制剂进行了体内研究,并与上市制剂进行了比较。根据ICH指南保留最终制剂用于稳定性研究。

In the field of pharmaceutical chemistry, impurities are considered as unwanted chemicals that present in the therapeutically active pharmaceutical compounds. They are unusually potent and expected to produce toxicity; hence it may be shows unexpected pharmacological actions which are harmful to human health. The control of impurities is currently a critical issue to the pharmaceutical industry. The most possible source of impurities is the synthesis that involves various steps, i.e. from starting materials to finished products through the intermediate steps. Impurities in drug substances and drug products are key regulatory issues in the office of generic drugs and have significant impact on the approvability of drugs hence International Conference on Harmonization (ICH) and Food and Drug Administration (FDA) guidelines introduce the identification and qualification procedures for them, by using various analytical techniques like TLC, LC, GC, MS, NMR, IR, UV, GC-MS, LC-MS, LC-NMR etc,.
在药物化学领域,杂质被认为是存在于治疗活性药物化合物中的不需要的化学物质。它们的效力异常强大,预计会产生毒性;因此,它可能表现出意想不到的药理作用,对人体健康有害。杂质的控制是目前制药行业的一个关键问题。最可能的杂质来源是涉及各种步骤的合成,即从起始材料到通过中间步骤的成品。原料药和药品中的杂质是仿制药办公室的关键监管问题,对药品的可批准性有重大影响,因此国际统一会议(ICH)和食品药品监督管理局(FDA)指南通过使用各种分析技术,如TLC, LC, GC, MS, NMR, IR, UV, GC-MS, LC-MS, LC-NMR等,介绍了它们的鉴定和鉴定程序。

The word ‘Beverage’ has been derived from the Latin word ‘bever’ meaning rest from work. At the most basic level, beverage are the portable drinks other than water that humans can consume to satisfy energy, thirst or hydration. Beverages are not usually consumed for their food value, but many, particularly the fruit drinks, contain quite a high percentage of sugar, vitamins and minerals, and, therefore, add to the energy content of the diet. They may be in the form of freshly squeezed juices to chemical-packed energy drinks. For hundreds of thousands of years, the idea of a beverage was restricted to water, milk or any fruit juice but with passage of time, there came alcohol, wine, various teas, coffees, cocktails, ciders and sodas, A wide range of plant materials are used to manufacture beverages. Broadly, there are two types of beverages alcoholic and nonalcoholic beverage”. Former is used as a generic term for beverages that contain more than 2.50% alcohol by volume, nevertheless such that the minimum age provision in applies to beverages containing between 0.70 and 2.50 per cent alcohol by volume. These include leaves, stems, sap, fruits, tubers, and seeds (grains). China and India are the fastest growing markets for non-alcoholic beverages.
“饮料”一词来源于拉丁语“bever”,意思是工作后的休息。在最基本的层面上,饮料是除了水以外的便携式饮料,人们可以饮用来满足能量,口渴或补水。人们饮用饮料通常不是因为它们的食物价值,但许多饮料,尤其是水果饮料,含有相当高比例的糖、维生素和矿物质,因此,增加了饮食中的能量含量。它们的形式可能是鲜榨果汁,也可能是化学包装的能量饮料。几十万年来,饮料的概念仅限于水、牛奶或任何果汁,但随着时间的推移,出现了酒精、葡萄酒、各种茶、咖啡、鸡尾酒、苹果酒和苏打水。各种各样的植物材料被用来制造饮料。从广义上讲,饮料分为“酒精饮料”和“非酒精饮料”两种。前者是指按体积计算酒精含量超过2.50%的饮料的通称,然而,最低年龄规定适用于按体积计算酒精含量在0.70至2.50%之间的饮料。这些包括叶子、茎、汁液、果实、块茎和种子(谷物)。中国和印度是非酒精饮料增长最快的市场。

Abuse and misuse of prescription opioids is a significant public health concern. The strategies used to confer abuse-deterrent properties on opioid abuse deterrent formulations (ADFs). The objective of this study was to develop techniques for an abuse deterrent (AD) platform utilizing the Granurex process. For the preparation of abuse deterrent extended release formulation core material was layered with dry active pharmaceutical ingredient with the help of Granurex technology and after the drug layering suitable polymeric coat was applied to make formulation crushed resistance and resistance to dose dumping. Formulation optimization was accomplished by utilizing full factorial design of experiments to determine the effect of the three formulation factors: Ethyl cellulose 45 cps, white wax and carbopol 974P NF; each of which was studied at three levels on crushed resistance (CR) attributes of the produced extended release pellets. Suitable formulation ingredients were employed as carrier matrices and processing aids. All of the formulations were evaluated for the crushed resistance and dose dumping attributes, such as crushing strength, extraction studies of drug in different levels of solvents and particle size . All of the design of experiments formulations demonstrated sufficient hardness and elasticity, and could not be reduced into fine particles , which is a desirable feature to prevent snorting. In addition, all of the formulations exhibited good gelling tendency in water with minimal extraction of drug in the aqueous medium. Moreover, Carbopol 974P NF, in combination with white wax, could be utilized to produce pellets with crushed resistance potential. Granurex has been demonstrated to be a viable technique with a potential of develop novel AD formulations.
处方类阿片的滥用和误用是一个重大的公共卫生问题。用于赋予阿片类药物滥用威慑制剂(adf)滥用威慑特性的策略。本研究的目的是利用Granurex工艺开发滥用威慑(AD)平台的技术。在制备防滥用缓释制剂时,利用Granurex技术将干燥的活性药物成分分层,并在药物分层后涂上合适的聚合物包被,使制剂具有抗压性和抗剂量倾倒性。采用全因子设计对配方进行优化,确定了乙基纤维素45 cps、白蜡和卡波波尔974P NF三个配方因素对配方的影响;对所制备的缓释微球的抗压性(CR)属性进行了三个层次的研究。选用合适的配方成分作为载体基质和工艺助剂。对所有制剂的抗压性和剂量倾倒特性进行了评价,如抗压强度、不同溶剂水平和粒径下药物的提取研究。所有实验配方的设计都表现出足够的硬度和弹性,不能被还原成细小的颗粒,这是防止喷鼻的理想特性。此外,所有的配方在水中均表现出良好的凝胶倾向,并且在水介质中提取的药物最少。此外,Carbopol 974pnf与白蜡结合可用于生产具有粉碎电阻电位的球团。Granurex已被证明是一种可行的技术,具有开发新型AD制剂的潜力。

Ion exchange resins are cross-linked water insoluble polymer-carrying, ionisable functional groups. IER have received considerable attention from pharmaceutical scientists because of their versatile properties as drug delivery vehicles. Research over the last few years has revealed that IER are equally suitable for drug delivery technologies, including controlled release, transdermal, nasal, topical and taste masking. The major drawback of sustained release of extended release or extended release is dose dumping, resulting in increased risk of toxicity. The use of IER has occupied an important place in the development of controlledor sustained-release systems because of their better drug-retaining properties and prevention of dose dumping. Synthetic ion exchange resins have been used in pharmacy and medicine for taste masking or controlled release of drug. Drug resin complexation converts drug to amorphous form leading to improved drug dissolution. Several studies have reported the use of IER for drug delivery at the desired site of action.
离子交换树脂是交联的水不溶性携带聚合物的可电离官能团。由于其作为药物传递载体的多用途特性,因此受到了药学科学家的广泛关注。过去几年的研究表明,IER同样适用于药物释放技术,包括控释、透皮、鼻、局部和味道掩蔽。缓释、缓释或缓释的主要缺点是剂量倾倒,导致毒性风险增加。由于其具有良好的保药性能和防止剂量倾倒,因此在控释或缓释系统的发展中占有重要地位。合成离子交换树脂已广泛应用于制药和医药领域,用于药物的味掩蔽或控释。药物树脂络合将药物转化为无定形,从而改善药物溶出度。一些研究已经报道了在期望的作用部位使用IER给药。
