The aim of present study was to determine the self-medication trends in children by their parents, knowledge of selfmedication and their attitude towards this practice. Factors that enforced them to do this practice were also determined along with their source of information about drug use. Total 400 parents were randomly selected and interviewed. It was observed that self-medication prevalence in children by their parents was 77.25% with male and female ratio 49% and 51%. Self-medication awareness was 66% among total parents and this practice was more in children of age 1-5 years i.e., 47%. Most common conditions for self-medication were fever, cough, flu, vomiting, diarrhoea and allergies. Frequently used drug groups include antipyretics, cough and cold preparation, antimicrobials, antiemetics and antiallergy. It was also observed that 45% of parents practiced self-medication 3-4 times per year and the main reasons behind this practice were perception of illness, previous experience, lack of time, financial constraint and leftover medicines. Old prescriptions, family members, friends and medical stores were common source of self-medication. This study also revealed that 57% of parents reported recovery after self-medication. It was also observed that 63% of parents informed physician about self-medication in their children and 18% reported that their child became sicker after self-medication. Out of total 56% participants were agreed that self-medication is unsafe for their children.
本研究的目的是了解儿童父母自我药疗的趋势、自我药疗的知识和态度。还确定了迫使他们这样做的因素以及他们关于吸毒的信息来源。随机抽取400名家长进行访谈。家长自我药疗率为77.25%,男女比例分别为49%和51%。在所有家长中,自我药疗意识为66%,在1-5岁的儿童中这种做法更多,即47%。自我用药最常见的情况是发烧、咳嗽、流感、呕吐、腹泻和过敏。常用药物包括退烧药、止咳和感冒药、抗菌剂、止吐药和抗过敏药。调查还发现,45%的家长每年自我药疗3-4次,其主要原因是对疾病的认知、既往经验、时间不够、经济拮据和剩余药物。旧处方、家庭成员、朋友和医药商店是自我药疗的常见来源。该研究还显示,57%的父母报告自我药物治疗后康复。研究还发现,63%的父母告知医生他们孩子的自我药疗,18%的父母报告说他们的孩子在自我药疗后病情加重。总共有56%的参与者同意自我药疗对他们的孩子不安全。

Background: Blepharospasm is a focal dystonia presented with continuous involuntary contractions of the muscles surrounding the eyes, causing frequent eyelid closure and visual disturbance. The current treatments for blepharospasm are not very satisfactory. This is a retrospective study of the therapeutic effect of dextromethorphan on blepharospasm. Methods: This retrospective study included 22 patients with essential blepharospasm, who were treated with dextromethorphan. The effect was evaluated using Jankovic Rating Scale (JRS) and Blepharospasm Disability Index (BSDI). Results: Before dextromethorphan treatment, the baseline JRS score is 5.55 ± 1.10 points, and the BSDI score was 2.87 ± 0.59 points. After 1 week of dextromethorphan treatment, the JRS score decreased to 2.82 ± 0.85 points, and the BSDI score decreased to 1.36 ± 0.58 points. In the following 3 weeks of treatment, the JRS and BSDI scores kept in a steady state. One week after the dextromethorphan treatment, the JRS score (5.41 ± 1.01 points) and BSDI score (2.63 ± 0.64 points) returned to the pre-treatment baseline level. Conclusion: We found that dextromethorphan is effective in patients with blepharospasm, and this finding might imply an alternative treatment option to blepharospams.
背景:眼睑痉挛是一种局灶性肌张力障碍,表现为眼睛周围肌肉的持续不自主收缩,引起频繁的眼睑闭合和视觉障碍。目前眼睑痉挛的治疗方法并不令人满意。这是一个回顾性研究右美沙芬治疗眼睑痉挛的效果。方法:回顾性研究22例应用右美沙芬治疗的原发性眼睑痉挛患者。采用Jankovic评定量表(JRS)和眼睑痉挛功能障碍指数(BSDI)对效果进行评价。结果:右美沙芬治疗前,基线JRS评分为5.55±1.10分,BSDI评分为2.87±0.59分。右美沙芬治疗1周后,JRS评分降至2.82±0.85分,BSDI评分降至1.36±0.58分。在接下来的3周治疗中,JRS和BSDI评分保持稳定。右美沙芬治疗1周后,JRS评分(5.41±1.01分)和BSDI评分(2.63±0.64分)恢复到治疗前基线水平。结论:我们发现右美沙芬对眼睑痉挛患者有效,这一发现可能意味着眼睑痉挛的另一种治疗选择。

The aim of present work is to determine and analyse the kinetics of drug release from the matrix tablet by employing various mathematical models. A study was done with Carbidopa and Levodopa ER tablets, 50 mg/200 mg by employing wet granulation technique using Hydroxypropyl methylcellulose and Hydroxypropyl cellulose as matrix forming polymer. The in-vitro drug release profile was carried out in 0.1 N HCl (900 mL) using USP dissolution apparatus II (Paddle) at 50 rpm at an extended time period of 0.5, 0.75, 1, 1.5, 2, 2.5, 3 and 4 hours. The drug release data was obtained, quantitatively correlated and interpreted with various mathematical models viz. Zero order model, first order model, Higuchi model, Hixson-Crowell model and Korsmeyer-Peppas model and evaluated to understand the kinetics of drug release. The criterion for the most suitable model was based on the high degree of coefficient of correlation of drug release profile of Carbidopa Levodopa ER Tablet. Hence, finally concluded as the drug release pattern of Carbidopa Levodopa ER Tablets, 50 mg/200 mg was best fitted with Higuchi square root model and follows Higuchi drug release kinetics which is diffusion controlled.

Olympiadane nanomolecules are a mechanically-interlocked molecule composed of five interlocking macrocycles that resembles the olympic rings. The nanomolecule is a linear pentacatenane or a catenane [1,2]. It was synthesized and named by Fraser Stoddart and co-workers in 1994 [1,2]. The molecule was designed without any practical use in mind, although other catenanes may have possible application to the construction of a molecular computer in Nano scale (Figures 1 and 2) [1,2]. Furthermore, Olympiadane nanomolecules are an important class of ring fused heterocyclic Nano compounds exhibit a wide spectrum of biological, medical, medicinal, pharmaceutical, chemical and clinical activities as agent for cancer enzymotherapy, immunotherapy, chemotherapy, radiotherapy, hormone therapy and targeted therapy under synchrotorn radiation [3–34]. Therefore, development of new and efficient synthetic method for the preparation of these Nano compounds is of importance in both synthetic organic chemistry and also medicinal and pharmaceutical chemistry. The classical synthesis, pharmacokinetics, pharmacodynamics, dosing, stability, safety and efficacy of Olympiadane nanomolecules mainly involve the use of acylchlordie and 2–pyridylalkylamine, followed by subsequent functionalization to anchor various electrophilic reagents. Other approaches include the use of imine derivatives, 2– cyanopyridine, and recently, benzotriazoles. During the course of our studies towards the development of new routes to the synthesis, pharmacokinetics, pharmacodynamics, dosing, stability, safety and efficacy of fused Nitrogen heterocyclic Nano compounds, we wish to introduce a valid and an efficient procedure for the synthesis, pharmacokinetics, pharmacodynamics, dosing, stability, safety and efficacy of Olympiadane nanomolecules via one–pot condensation of pyridyl ketone with aldehyde and NH4OAc in the presence of Lithium Chloride as an inexpensive neutral Lewis acid using microwave irradiation.
奥林匹亚烷纳米分子是一种机械互锁的分子,由五个互锁的大环组成,类似于奥林匹克五环。纳米分子是线性的五正戊烷或正戊烷[1,2]。1994年由Fraser Stoddart等人合成并命名[1,2]。该分子的设计没有考虑到任何实际用途,尽管其他链烷可能在纳米尺度上应用于分子计算机的构建(图1和2)[1,2]。此外,奥林匹亚烷纳米分子是一类重要的环融合杂环纳米化合物,作为癌症酶治疗、免疫治疗、化疗、放疗、激素治疗和同步辐射靶向治疗的药物,具有广泛的生物学、医学、药用、制药、化学和临床活性[3-34]。因此,开发新的高效的合成方法制备这些纳米化合物在合成有机化学和药物化学领域都具有重要意义。奥林匹亚烷纳米分子的经典合成、药代动力学、药效学、给药、稳定性、安全性和有效性主要涉及使用酰基氯代和2 -吡啶烷基胺,随后进行功能化以锚定各种亲电试剂。其他方法包括使用亚胺衍生物,2 -氰吡啶,以及最近使用的苯并三唑。在我们研究融合氮杂环纳米化合物的合成、药代动力学、药效学、给药、稳定性、安全性和有效性的新途径的发展过程中,我们希望介绍一种有效和有效的合成、药代动力学、药效学、给药、稳定性、吡啶酮与醛、NH4OAc在廉价中性Lewis酸氯化锂存在下,微波辐照一锅缩合制备纳米分子奥林匹亚烷的安全性和有效性。

Obesity is an epidemic in the United States, and affects around onethird of the population in the United States. Diagnosis of obesity is generally based on body mass index (BMI), which estimates total body fat content. BMI is calculated by dividing body weight (in kilograms) over body surface area (in meters squared). Based on the standards established by the National Heart, Lung, and Blood Institute, normal weight is defined as BMI of 18.5 to 24.9 kg/m2. Patients with BMI of 25 to 29.9 kg/m2 are considered to be overweight, while those with BMI greater than 30 are classified as being obese. The obese category is further divided into 3 categories: grade 1 (BMI 30 to 34.9 kg/m2), grade 2 (BMI 35 to 39.9 kg/m2), and grade 3 (BMI of 40 or higher) [1]. However, the association between obesity and cardiovascular (CV) disease is not clearly established, and being underweight may even increase the risk of heart disease.
肥胖在美国是一种流行病,影响着大约三分之一的美国人口。肥胖的诊断通常是基于身体质量指数(BMI),它估计身体总脂肪含量。BMI的计算方法是体重(公斤)除以体表面积(平方米)。根据国家心肺血液研究所制定的标准,正常体重的定义是BMI在18.5到24.9 kg/m2之间。BMI为25 ~ 29.9 kg/m2为超重,BMI大于30为肥胖。肥胖类别又分为三级:1级(BMI 30 ~ 34.9 kg/m2)、2级(BMI 35 ~ 39.9 kg/m2)、3级(BMI 40及以上)[1]。然而,肥胖与心血管(CV)疾病之间的关系尚不明确,体重过轻甚至可能增加患心脏病的风险。

In present study, some 4-piperidinopiperidine (PP) and 4-amino methylpiperidine (AMP) derivatives (PP1-3 and AMP4-9) have been synthesized to explore their analgesic potential. Activity of compounds evaluated by in-vivo thermal (tail immersion) method produced significant analgesia at different doses. Docking results explained good binding affinity of synthesized derivatives and potential interaction of all compounds with mu-opioid receptor. The pharmacophoric model of synthesized compounds showed possible structural features required for analgesic activity when compared with standards (Fentanyl, Morphine, Pethidine). Among all PP1, AMP5 and AMP6 emerged out as potent analgesic agents. Graphical abstract

Since, the last four decades, the concept of mucoadhesion has achieved a much valuable interest in the various fields of pharmaceutics. There are many advantages of mucoadhesive buccal drug delivery system that made this a novel drug delivery system for the local as well as systemic delivery of various drugs. The main advantage of this drug delivery system is that it prolongs the residence time of the dosage form at the site of application. Due to the high blood supply and relatively high permeability of the buccal mucosa, the buccal cavity is the best option for both local as well as systemic delivery of various drugs. The term bioadhesion can be defined as a phenomenon of interfacial molecular attractive forces in the midst layer of surface of a biological membrane and the natural or synthetic polymers, which allows the polymer to adhere the surface of that membrane for an extended as well as prolonged period of time. In this review we have discussed the various types of mucoadhesive dosage forms along with a brief knowledge about the various types of mucoadhesive polymers. The buccal mucoadhesive dosage forms can be either of matrix or of reservoir types. The main advantage of this route for drug delivery is that, the delivery by this route by passes the first pass metabolism of various drugs that are prone to the their hepatic first pass metabolism. This review provides the brief knowledge about the oral mucosal drug delivery by discussing briefly the structural features of mucosa, mechanism of bioadhesion, various theories of bioadhesion, general considerations in design of mucoadhesive buccal dosage forms, permeation enhancers, and the various evaluation methods along with the literature survey of the buccal mucoadhesive drug delivery system.
由于,在过去的四十年中,粘液粘附的概念已经在制药的各个领域取得了非常有价值的兴趣。黏附口腔给药系统具有许多优点,使其成为一种既可局部给药又可全身给药的新型给药系统。这种给药系统的主要优点是它延长了剂型在施用部位的停留时间。由于口腔粘膜的高血供和相对高的渗透性,无论是局部还是全身给药,口腔都是最佳的选择。术语生物粘附可以定义为生物膜和天然或合成聚合物表面中间层中界面分子吸引力的现象,它允许聚合物在延长的时间内粘附在该膜的表面。在这篇综述中,我们讨论了各种类型的黏合剂剂型,并简要介绍了各种类型的黏合剂聚合物。口腔黏合剂剂型可以是基质型或储液型。这种给药途径的主要优点是,这种给药途径通过了各种药物的一次过代谢,这些药物容易发生肝脏一次过代谢。本文通过对口腔黏膜给药系统的文献综述,简要介绍口腔黏膜给药系统的结构特点、生物黏附机制、各种生物黏附理论、黏附口腔给药剂型设计的一般注意事项、渗透增强剂、各种评价方法等。

The present study concerns behavioral, biochemical and hematological effects of new synthesized adrenergic related compound 1-(3, 4-dihydroxyphenyl)-2-(4-methylpiperidin-1-yl) ethan-1-one, which have similar structural activity to adrenergic receptor agonist. With intraperitoneal injection in rats, stimulatory activity in home cage, anxiolytic effect in light and dark and locomotors activity in open field were significantly increased. Biochemical effects of glucose and cholesterol were checked by kit (CHOD-PAP) method were significantly decreased. Liver enzymes including, Alkaline Phosphatase (ALP) and SGOT were markedly decreased but, Alanine aminotransferase (ALT) level was markedly increased. In hematological study, after administration of compound hemoglobin (Hb) level was significantly increased in test group of rats. Results indicate that new adrenergic related antidepressant compound not only enhanced the stimulation, locomotion and released depression and anxiety but also, this antidepressant compound show more effectiveness in depression to prevent diabetes and heart diseases.
新合成的肾上腺素能相关化合物1-(3,4 -二羟基苯基)-2-(4-甲基哌啶-1-基)e比-1- 1具有与肾上腺素能受体激动剂相似的结构活性,研究其在行为学、生化和血液学方面的作用。腹腔注射后,大鼠在家笼中的刺激活性、明暗环境下的抗焦虑作用和开阔环境下的运动活性均显著增加。葡萄糖、胆固醇等生化指标均显著降低。肝酶包括碱性磷酸酶(ALP)和SGOT显著降低,而丙氨酸转氨酶(ALT)显著升高。在血液学研究中,给药后试验组大鼠血红蛋白(Hb)水平明显升高。结果表明,新型肾上腺素能类抗抑郁药不仅能增强刺激和运动,释放抑郁和焦虑,而且对抑郁症有较好的预防作用,可预防糖尿病和心脏病。
