Background: Dispensing antibiotics without a prescription at community pharmacies is a significant contributor to the ongoing global public health issue of antibiotic resistance. Objectives: To estimate the proportion of antibiotics that are dispensed without a prescription in community pharmacies in various Indonesian cities. Methods: A literature review was conducted via PubMed, Science Direct, Google Scholar, Garuda, and Neliti for articles published between January 2007 and December 2022 combined with Boolean operators. The literature search keywords were (simulated patientsOR mystery shopper OR sample patients OR dummy patients) AND ("antibiotics without prescription OR non-prescription antibiotics OR self-medication of antibiotics). The keywords are also used in Indonesian language (Bahasa), including “simulasi pasien” OR “sampel pasien” AND “antibiotik tanpa resep” OR “swamedikasi antibiotik”. Results: Seven studies from various cities have complied with the inclusion criteria and were considered when reviewing 199 articles. The findings of our studies were consistent with the extensive use of non-prescription antibiotics throughout the review. A simulation patient study design was used in all seven studies in this review. Amoxicillin recorded the highest percentage of dispensing without a prescription, while other drugs often purchased include chloramphenicol, ciprofloxacin, and cefadroxil. Among the studies reviewed, one study utilized the pre-test and post-test methods, while the others did not. Conclusion: The lack of prescriptions for antibiotics dispensing has often occurred in community pharmacies throughout Indonesia. The community pharmacist's role is needed as the final gate of pharmaceutical services in providing rational treatment and controlling the dispense of antibiotics without a prescription.
背景:在社区药房无处方分发抗生素是造成抗生素耐药性这一持续的全球公共卫生问题的一个重要因素。目的:估计印度尼西亚各城市社区药房无处方分配抗生素的比例。方法:结合布尔运算符,通过PubMed、Science Direct、Google Scholar、Garuda和Neliti对2007年1月至2022年12月间发表的文章进行文献综述。文献检索关键词为(模拟患者或神秘购物者或样本患者或虚拟患者)和(无处方抗生素或非处方抗生素或自行用药抗生素)。这些关键词也用在印尼语中,包括“simulasi pasien”或“sampel pasien”和“antibiotic tik tanpa resep”或“swamedikasi antibiotic tik”。结果:来自不同城市的7项研究符合纳入标准,共纳入199篇文献。我们的研究结果与整个综述中非处方抗生素的广泛使用一致。本综述的所有7项研究均采用模拟患者研究设计。阿莫西林在没有处方的情况下配药的比例最高,而其他经常购买的药物包括氯霉素、环丙沙星和头孢醚。在回顾的研究中,一项研究使用了前测和后测方法,而其他研究则没有。结论:印度尼西亚社区药房经常出现抗生素配药处方不足的情况。社区药师作为药学服务的最后一扇门,在提供合理治疗和控制无处方抗生素配药方面发挥着重要作用。

Background: Diabetes mellitus is a chronic metabolic disorder that cannot be cured and progressively develop into a complication affecting the patient's health-related quality of life (HRQoL). The utility is a measure of preference-based HRQoL. Indirect utility measurements can be measured using the Multi-Attribute Utility Instrument (MAUI) instrument, one of which is the 15D questionnaire that has never been translated and adapted culturally in Indonesian. Objective: Translating and culturally adapting the 15D questionnaire to Indonesian diabetes mellitus patients. Methods: The translation process was carried out through the stages of forward translation, reconciliation, and backward translation involving two qualified translators and three experts in their field. The pilot test stage involved eight respondents consisting of 6 diabetes mellitus patients and two healthy individuals. Results: Problems in the linguistic validation process led to more conformity of word equivalents from the original to the target language. The agreement found was in the area of semantic equivalence, idiomatic equivalence, and experiential equivalence. The problem was resolved by reconciliation during the Focus Group Discussion, which translators and experts in their field attended and discussed with the original author to get equality of meaning in terms of language and culture. The Indonesian version of the 15D questionnaire tested on eight respondents showed results that were easy to understand and straightforward. Conclusion: The Indonesian version of the 15D questionnaire is valid from the linguistic and cultural adaptation stage. Further research is needed relating to the validation and reliability of the questionnaire.

Background: Fucoidan is sulfated polysaccharide that has gastroprotector activity, and it is distributed in brown algae cell walls. Currently, there is no method for fucoidan analysis in compendia. Furthermore, analysis of Fucoidan is proven to be challenging due to the lack of chromophores and its high polarity. Objective: To develop the optimal condition of TLC-Densitometry method for fucoidan analysis in Sargassum sp. aqueous extract and to evaluate the stability of Fucoidan as a preliminary study. Methods: Chromatography was performed on Silica gel 60F254 TLC-plate as a stationary phase. The developed plate was stained with H2SO4 10% in absolute ethanol and heated in oven at 105°C for 15 minutes. Optimization is carried out by determining composition of the mobile phase, analytical wavelength, and spotting volume. Stability test of Fucoidan in standard and extract solution at 0, 4, 8, and 24 hours also 0 and 60 minutes after derivatization. Results: The optimal condition which produces a good separation of Fucoidan was achieved by using n-butanol:methanol: water (10:6:10 v/v/v) as a mobile phase, 400 nm as an analytical wavelength, and 1 µl as a spotting volume. Fucoidan was stable after storage until 24 hours. The stained spots were stable until 60 minutes after derivatization. Conclusion: Optimal condition of the TLC-Densitometry method for Fucoidan analysis was selective and can be applied to stability tests in preliminary study. Fucoidan was stable in standard solution and extracted solution until 24 hours after storage at 4°C, and the stained spots were stable until 60 minutes after derivatization.
背景:褐藻多糖是一种具有胃保护作用的硫酸酸化多糖,分布于褐藻细胞壁中。目前,在药典中还没有分析褐藻糖聚糖的方法。此外,由于缺乏发色团和其高极性,岩藻聚糖的分析被证明是具有挑战性的。目的:建立薄层色谱-密度法分析马尾藻水提物中褐藻多糖的最佳条件,并对褐藻多糖的稳定性进行初步研究。方法:以硅胶60F254薄层色谱板为固定相进行色谱分析。用10%无水乙醇中的H2SO4染色,在105℃烤箱中加热15分钟。通过确定流动相的组成、分析波长和斑点体积进行优化。岩藻糖聚糖在标准液和萃取液中衍生后0、4、8、24小时及0、60分钟的稳定性试验。结果:以正丁醇:甲醇:水(10:6:10 v/v/v)为流动相,分析波长为400 nm,点样量为1µl,获得了分离岩藻多糖的最佳条件。褐藻糖聚糖保存至24小时后稳定。直到衍生后60分钟,染色斑点都是稳定的。结论:薄层色谱-密度法分析岩藻多糖的最佳条件具有选择性,可用于初步研究的稳定性试验。褐藻糖聚糖在标准溶液和提取液中4℃保存24小时后稳定,衍生化后60分钟染色斑点稳定。

Background: Puskesmas is a primary healthcare facility that conducts chronic disease management, such as hypertension. The role of pharmacists in team collaboration includes that of managerial and clinical pharmacies. However, doctors and nurses still need to be fully aware of the role of pharmacists, particularly in clinical pharmacies. Objective: This study aimed to determine the perspectives of pharmacists, doctors, and nurses on the collaborative management of hypertension in health centres across the Central Lombok Regency. Methods: observational qualitative method with a maximum variation sampling technique was used. Data saturation was achieved after interviewing 27 participants between April and June 2023. Participants were pharmacists, doctors, and nurses responsible for managing hypertension in the selected primary healthcare centers. Results: Five main themes were identified. The first was a perspective on pharmacists’ managerial and clinical pharmacy roles. Almost all participants agreed that pharmacists played more roles in ensuring the availability of hypertension drugs than clinical pharmacies. Four themes were derived from a conceptual framework related to team readiness to collaborate: cognitive, affective/relational, behavioral, and leadership aspects. In general, doctors and nurses need to be made aware of pharmacists' role in the area of clinical pharmacy; meanwhile, pharmacists need to improve their clinical pharmacy knowledge. Meanwhile, team collaboration has not run optimally because each team member works individually rather than as a team member. Conclusion: Pharmacists need to improve their clinical pharmacy role, be more involved in team collaborations, and be more engaged in team collaborations; efforts are required to prepare for team collaboration.
背景:Puskesmas是一个初级卫生保健机构,进行慢性疾病管理,如高血压。药师在团队协作中的作用包括管理药师和临床药师的作用。然而,医生和护士仍然需要充分认识到药剂师的作用,特别是在临床药房。目的:本研究旨在确定药师、医生和护士对整个龙目岛中部医疗中心高血压协同管理的看法。方法:采用最大变异抽样观察定性方法。在2023年4月至6月期间采访了27名参与者后,数据达到饱和。参与者是在选定的初级卫生保健中心负责管理高血压的药剂师、医生和护士。结果:确定了五个主要主题。第一个是对药剂师的管理和临床药学角色的看法。几乎所有的参与者都同意药剂师在确保高血压药物的可获得性方面比临床药房发挥更大的作用。从与团队合作意愿相关的概念框架中衍生出四个主题:认知、情感/关系、行为和领导方面。总的来说,医生和护士需要了解药剂师在临床药学领域的作用;同时,药师的临床药学知识也有待提高。与此同时,由于每个团队成员都是单独工作,而不是作为团队成员工作,因此团队协作没有达到最佳状态。结论:药师需完善临床药学角色,更多地参与团队协作,更积极地参与团队协作;需要努力为团队协作做准备。

Background: CIPN (Chemotherapy-induced Peripheral Neuropathy) primarily affects the sensory system and is accompanied by pain, autonomic dysfunction, and motor impairments. Alterations of intracellular second messengers at the supraspinal level in CIPN needed to be explored more. In addition, there is a lack of evidence regarding implications for the supraspinal area through the propagation of pain via the ascending pathway. Objective: In this study, we evaluated the effect of fenofibrate as a PPARα agonist in suppressing the development of CIPN. Methods: Twenty-four mice were distributed to the normal control group, neuropathy group, and neuropathy with the treatment of fenofibrate 75 and 150 mg/kg groups, resulting in 6 animals per group. Oxaliplatin was injected on days 0, 2, 4, and 6. The hot plate test was performed before the oxaliplatin administration and then continued on the 7th, 14th, and 21st days. Thalamus tissues were collected to measure the TRPA1 mRNA expression using qPCR. Results: Fenofibrate 75 mg/kg co-treatment with oxaliplatin tended to prevent the enhancement of oxaliplatin-induced thermal hyperalgesia in hind-paw withdrawal and rubbing responses. Furthermore, fenofibrate 75 and 150 mg/kg co-treatment with oxaliplatin significantly reduced the relative TRPA1 mRNA expression but did not modulate the relative BDNF mRNA expression in the thalamus. Conclusion: PPARα agonist has a potential effect in suppressing the development of CIPN. However, given the various perspectives on the role of neurotrophins in CIPN, additional non-clinical investigations, are needed to provide more insight into other mechanisms of CIPN and the role of PPAR agonists.
背景:化疗诱导的周围神经病变(CIPN)主要影响感觉系统,并伴有疼痛、自主神经功能障碍和运动障碍。CIPN棘上水平细胞内第二信使的改变需要进一步探讨。此外,缺乏证据表明疼痛通过上升通路传播对棘上区有影响。目的:在本研究中,我们评估非诺贝特作为PPARα激动剂对CIPN发展的抑制作用。方法:将24只小鼠分为正常对照组、神经病变组和神经病变非诺贝特75、150 mg/kg组,每组6只。在第0、2、4、6天注射奥沙利铂。热板试验于奥沙利铂给药前进行,并于第7、14、21天继续进行。收集丘脑组织,采用qPCR检测TRPA1 mRNA的表达。结果:非诺贝特75mg /kg与奥沙利铂联用可预防奥沙利铂引起的热痛觉后足退摩反应的增强。此外,非诺贝特75和150 mg/kg与奥沙利铂联合治疗显著降低了TRPA1 mRNA的相对表达,但没有调节丘脑中BDNF mRNA的相对表达。结论:PPARα激动剂具有抑制CIPN发生的潜在作用。然而,鉴于神经营养因子在CIPN中的作用的各种观点,需要更多的非临床研究来深入了解CIPN的其他机制和PPAR激动剂的作用。

Background: Wound is a condition where there is damage or disruption to the anatomical structure and function of the skin. Wounds that are not treated properly can lead to infection. As wound dressings, film dressings have many advantages such as being elastic, flexible, transparent, and can adapt to the wound shape. Film’s characteristics of are affected by the plasticizer and the polymer. Combination of chitosan and polyvinyl alcohol (PVA) is able to improve the mechanical properties of the film such as its swelling capacity, tensile strength, and elongation at break. Objective: This study aims to determine the effects of chitosan and PVA in various concentrations on the physical characteristics and mechanical properties of the film. Methods: Film was prepared by solvent casting method, using chitosan and alginate in various concentrations of 0% to 1.5%, 1.5% Aloe vera, and 6% propylene glycol. Films’ characteristics and mechanical properties were evaluated, such as swelling index, tensile strength, elongation at break, and Young’s modulus. Results: The result showed that chitosan and PVA polymers had a significant effect on the swelling index, tensile strength, elongation at break, and Young’s modulus. The effect of chitosan and PVA combination on the swelling index, tensile strength, and elongation at break is due to the hydrogen bonding between the hydroxyl group of PVA and the amine group of chitosan. Conclusion: The combination of chitosan and polyvinyl alcohol influenced the film's physical and mechanical properties. Film with chitosan and polyvinyl alcohol ratio of 1.5%:1.5% have best characteristics compared to others.
背景:伤口是皮肤解剖结构和功能受到损伤或破坏的一种情况。伤口处理不当会导致感染。膜敷料作为伤口敷料,具有弹性好、柔韧性好、透明、能适应伤口形态等优点。增塑剂和聚合物对薄膜的性能有影响。壳聚糖和聚乙烯醇(PVA)的结合可以改善薄膜的力学性能,如膨胀能力、抗拉强度和断裂伸长率。目的:研究不同浓度的壳聚糖和聚乙烯醇对薄膜物理特性和力学性能的影响。方法:以0% ~ 1.5%浓度的壳聚糖和海藻酸盐、1.5%芦荟、6%丙二醇为原料,采用溶剂铸造法制备膜。对薄膜的特性和力学性能进行了评价,如膨胀指数、拉伸强度、断裂伸长率和杨氏模量。结果:壳聚糖和聚乙烯醇聚合物对膨胀指数、抗拉强度、断裂伸长率和杨氏模量均有显著影响。壳聚糖与PVA复合对膨胀指数、抗拉强度和断裂伸长率的影响是由于PVA的羟基与壳聚糖的胺基之间的氢键作用。结论:壳聚糖与聚乙烯醇复合对膜的物理力学性能有影响。壳聚糖与聚乙烯醇配比为1.5%时,薄膜性能最佳。

This study examined the tyrosinase inhibitory potential of bengkoang peel standardised ethanolic extract and ethyl acetate fractions. 450 g of bengkoang peel powder (Pachyrhizus erosus L.) was macerated with 96% ethanol for 2 x 24 h, filtered, and concentrated till viscous. Extract standardisation uses specific and non-specific parameters. Microplate colorimetric tyrosinase inhibition assays were performed. The result of plant determination identified the bengkoang peel as Pachyrhizus erosus (L.) Urb. The organoleptic test revealed a brownish-yellow viscous extract, fresh smell, and bitter taste. Ethanol-soluble extract was 47.60% and water-soluble 22.42%. Bengkoang peel ethanolic extract includes alkaloids, flavonoids, saponins, tannins, and steroids. The non-specific parameters showed loss of drying (9.71%), water content (7.28%), total ash (9.91%), acid-insoluble ash (3.68%), no residual solvent content, lead content (-0.2324±0.1729), cadmium content (-0.0841±0.3418), TPC of 1 x 101 CFU/g, and TYMC of 2.26 x 102 CFU/g. The ethanol extract (103.9263) and ethyl acetate fraction (81.8606) IC50 values of bengkoang peel decrease tyrosinase enzyme activity compared to control (25.1235 ppm). These results show that the ethanol extract met both particular and non-specific quality standards. Bengkoang peel ethyl acetate inhibited tyrosinase.
本研究考察了蚌壳皮标准乙醇提取物和乙酸乙酯提取物对酪氨酸酶的抑制作用。取450 g槟榔果皮粉(Pachyrhizus erosus L.),用96%乙醇浸泡2 × 24 h,过滤浓缩至粘稠。提取标准化使用特定和非特定参数。进行微孔板比色法酪氨酸酶抑制试验。植物测定结果鉴定蚌壳果皮为厚根茎(Pachyrhizus erosus)。市区。感官测试显示一种棕黄色粘稠的提取物,气味清新,味道苦涩。乙醇溶性为47.60%,水溶性为22.42%。槟榔皮乙醇提取物包括生物碱、类黄酮、皂苷、单宁和类固醇。非特异性参数为干燥损失(9.71%)、含水量(7.28%)、总灰分(9.91%)、酸不溶灰分(3.68%)、无残留溶剂含量、铅含量(-0.2324±0.1729)、镉含量(-0.0841±0.3418)、TPC为1 × 101 CFU/g、TYMC为2.26 × 102 CFU/g。槟榔果皮乙醇提取物(103.9263)和乙酸乙酯部分(81.8606)IC50值较对照(25.1235 ppm)降低了酪氨酸酶活性。结果表明,乙醇提取物既符合特定质量标准,又符合非特定质量标准。槟榔皮乙酸乙酯对酪氨酸酶有抑制作用。

Black Sea cucumbers (Holothuria atra) are a potential source of active metabolites such as flavonoids widely used for nutraceutical, pharmaceutical, and cosmeceutical products. The type of nanoparticle that is often used in cosmetics and skin products is Solid Lipid Nanoparticles (SLN). In this study, the SLN of black sea cucumber extract will be prepared in the form of a peel-off gel mask as an antioxidant. Black sea cucumbers were extracted using the maceration method, while SLN preparation used high-shear homogenization and freeze-drying methods. Crude extract and SLN were formulated into peel-off gels and then evaluated, including organoleptic, homogeneity, viscosity, pH, spreadability, drying time, tensile strength test, and antioxidant activity using the DPPH method. The IC50 values of blank (F1), peel-off gel extract (F2), and nanoparticle peel-off gel extract (F3) were each 600.8727 ± 0.43; 580.7849±0.7; and 592.76±0.55 µg/mL. In conclusion, the SLN method can be applied to the formulation of black sea cucumber extract nanoparticles. However, peel-off gel masks from the crude and nanoparticle extracts have very weak antioxidant activity.
黑参(Holothuria atra)是活性代谢物(如类黄酮)的潜在来源,广泛用于营养品、制药和药妆产品。通常用于化妆品和皮肤产品的纳米颗粒类型是固体脂质纳米颗粒(SLN)。在本研究中,将黑海参提取物作为抗氧化剂,以剥脱凝胶面膜的形式制备SLN。黑参的提取采用浸渍法,SLN的制备采用高剪切均质和冷冻干燥法。将粗提物和SLN配制成剥离凝胶,并采用DPPH法对其感官、均匀性、粘度、pH、涂抹性、干燥时间、拉伸强度试验和抗氧化活性进行评价。空白(F1)、剥脱凝胶提取物(F2)、纳米颗粒剥脱凝胶提取物(F3)的IC50值分别为600.8727±0.43;580.7849±0.7;592.76±0.55µg/mL。综上所述,SLN法可用于黑参提取物纳米粒的制备。然而,从原油和纳米颗粒提取物中剥离的凝胶面膜具有非常弱的抗氧化活性。
