Background: Tracheal intubation is frequently associated with cardiovascular stress response characterized by hypertension, tachycardia and increased serum concentration of catecholamines and similar phenomenon is also seen during extubation. During Endotracheal extubation increase in sympathoadrenergic activity is caused by epipharyngeal and laryngopharyngeal stimulation. Objective: The aim and objectives of this study are to compare the effect of combination of intravenous (i.v.) diltiazem 0.1 mg/kg and i.v lignocaine 1.0 mg/kg vs intravenous lignocaine alone to attenuate haemodynamic extubation responses and airway reflexes during extubation. Material and method: This study was undertaken with 72 patients belonging to the age group 20–60 years with physical status ASA Classes I and II of either sex. Group A received injection diltiazem 0.1 mg/kg and lignocaine 1 mg/kg. Group B received injection lignocaine 1 mg/kg with normal saline. In this study, the drug dosage was fixed based on the previous studies. Result: The baseline values of heart rate,systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) were statistically comparable between the two groups. The heart rate, SBP, DBP, and MAP was significantly high in group A (lignocaine) as compared to group B (diltiazem with lignocaine) at extubation and till 1 min, 3 min, 5 min, and 10 min post extubation (pvalue < 0.05). Conclusion: Combined diltiazem and lignocaine provides more effective prophylaxis than lignocaine alone for attenuating the cardiovascular responses to tracheal extubation
背景:气管插管常伴有以高血压、心动过速和血清儿茶酚胺浓度升高为特征的心血管应激反应,拔管时也可出现类似现象。在气管内拔管时,交感神经肾上腺素能活动的增加是由咽上皮和喉部刺激引起的。目的:本研究的目的和目的是比较静脉滴注地尔硫卓0.1 mg/kg和静脉滴注利多卡因1.0 mg/kg与单独静脉滴注利多卡因对减轻拔管时血流动力学反应和气道反射的效果。材料和方法:本研究纳入72例年龄在20-60岁,身体状况ASA I级和II级的男女患者。A组注射地尔硫卓0.1 mg/kg,利多卡因1 mg/kg。B组注射利多卡因1 mg/kg,加生理盐水。本研究在前人研究的基础上确定了药物剂量。结果:两组患者心率、收缩压(SBP)、舒张压(DBP)、平均动脉压(MAP)基线值比较,差异均有统计学意义。拔管时A组(利多卡因组)及拔管后1、3、5、10 min的心率、收缩压、舒张压、MAP均显著高于B组(地尔硫卓+利多卡因组)(p值< 0.05)。结论:地尔硫卓与利多卡因联用对减轻气管拔管后心血管反应的预防效果优于利多卡因单用

Background: Ultrasonography-assisted supraclavicular block is an efficacious and practical method and allows us to use a lower volume of local anesthetic in compactly arranged brachial plexus. The study envisioned evaluating the analgesic and anesthetic effects of Inj. dexamethasone (8mg) as an adjuvant to 0.5% levobupivacaine to determine the time for first rescue analgesia and number of rescue analgesics needed in 24 hours duration in brachial plexus blockade in adult patients listed for upper limb surgeries. Results: This prospective randomized double-blind interventional study was carried out in ASAI and II, aged 20 to 55 years. In group A (n=30) Inj. Levobupivacaine 20ml and Inj. Normal saline 2ml was given. In group B (n=30) Inj. Levobupivacaine 20ml and Inj. Dexamethasone 2ml was given. The time for the demand of the first rescue analgesia was 431.50 ± 46.15 minutes in group A and 749.38 ± 62.41 minutes in group B, with a p-value < 0.001. The demand for rescue analgesics was more in Group A in contrast to Group B. Conclusion: We deduce with our study, with the addition of dexamethasone, the time for rescue analgesia is prolonged, and the number of rescue analgesic demands is reduced, with a faster onset and extended duration of both sensory and motor block.

Inflammation is a vital therapeutic target for creating new methods for pharmacological interventions, aside from being a stage in the pathophysiology of many diseases, such as atherosclerosis and rheumatoid arthritis. Thus, molecular understanding of inflammation has led to new opportunities for drug creation and significant new implications for current clinical medicine. It has also revealed the biological targets and mechanisms of therapeutic action, opening up new opportunities to alter complex biological systems. Meanwhile, using medicinal plants to control inflammation has been recommended as an alternative to traditional therapeutic approaches for a variety of conditions, particularly when suppression of inflammation is anticipated. Several medicinal plant species have been demonstrated to have strong anti-inflammatory properties in contemporary research. The review article was discussed about the chemical constituents and biological properties of therapeutically active plants including curcumin from Curcuma longa and epigallocatechin-3-gallate from Camellia sinensis, including the molecular pharmacology of active constituents against inflammation.
炎症是创造药物干预新方法的重要治疗靶点,也是许多疾病(如动脉粥样硬化和类风湿性关节炎)病理生理学的一个阶段。因此,对炎症的分子理解为药物创造带来了新的机会,并对当前的临床医学产生了重大的新影响。它还揭示了治疗作用的生物学靶点和机制,为改变复杂的生物系统开辟了新的机会。同时,使用药用植物来控制炎症已被推荐作为传统治疗方法的替代方案,用于各种情况,特别是当炎症被预期抑制时。在当代研究中,一些药用植物物种已被证明具有很强的抗炎特性。本文综述了姜黄素和茶树没食子儿茶素-3-没食子酸酯的化学成分和生物学特性,并对活性成分的抗炎分子药理学进行了综述。

The present study was conducted in Department of Anaesthesia, Sardar Patel Medical College and PBM Hospital, Bikaner, with the aim of comparative evaluation of subclavian vein catheterization by supraclavicular and infraclavicular approach. There are three common routes of central venous catheterization i.e. subclavian, internal jugular and the femoral. Hence in our study we have done a comparative evaluation of supraclavicular and infraclavicular approach for SCV catheterization with primary objective of successful catheterization of SCV using anatomical landmark technique and secondary objective of first attempt success rate, time taken for cannulation and also record the incidence of complications related to either approach. In our study, 60 patients enrolled were randomly divided into two groups of 30 patients each. In Group A Infraclavicular SCV catheterization and in Group B Supraclavicular catheterisation was performed using anatomical landmark approach. Successful catheterization, first attempt success rate, time taken for venous access and catheterization, catheter malfunction or any other complication were recorded. In group A (IC) Maximum 63.33% were inserted in single attempt whereas minimum 10% required 3 or more attempts while in group B (IC) maximum 93.33% were inserted in single attempt whereas minimum 3.33% needed 3 or more attempts, and the difference was found statistically significant. Overall successful catheterization was 90% in Group A and 96% in Group B while 93 % when combined for both groups. Mean time taken for insertion was observed more (6.67 ± 1.44 min.) in group A whereas less (4.47 ± 1.01min.) in group B, and the difference was found statistically highly significant. We conclude that SC approach of SCV catheterization is better as comparable to IC approach in terms of landmarks accessibility, success rate, time taken and rate of complications.
本研究在Sardar Patel医学院麻醉科和Bikaner PBM医院进行,目的是比较评价锁骨上入路和锁骨下入路锁骨下静脉置管术。有三种常见的中心静脉置管路径,即锁骨下、颈内和股静脉置管。因此,在我们的研究中,我们对锁骨上入路和锁骨下入路SCV置管进行了比较评估,主要目的是利用解剖地标技术成功置管SCV,次要目的是首次尝试成功率,插管时间,并记录两种入路相关并发症的发生率。在我们的研究中,60名患者被随机分为两组,每组30名患者。A组采用锁骨下SCV置管,B组采用锁骨上标记入路置管。记录置管成功率、首次成功率、静脉进入置管时间、导管故障或其他并发症。A组(IC)最多63.33%的人单次插入,最少10%的人需要3次及以上插入;B组(IC)最多93.33%的人单次插入,最少3.33%的人需要3次及以上插入,差异有统计学意义。A组插管成功率为90%,B组为96%,两组联合插管成功率为93%。A组平均插入时间更长(6.67±1.44 min), B组平均插入时间更短(4.47±1.01min),差异有统计学意义。我们得出结论,SCV导管的SC入路在标志可及性、成功率、所需时间和并发症发生率方面优于IC入路。

The objective of this study was to assess the efficacy of several taste-masking techniques and to study the impact of different formulation variables on the physicochemical properties of dispersible tablets containing Ranitidine as a model drug. Ranitidine powder was taste masked using various techniques. Factorial design (24) was applied to design the set of tablet formulations. The four factors implemented were the manufacturing method, filler type, superdisintegrant type and superdisintegrant concentration. Levels selected were direct compression and wet granulation for the manufacturing method, microcrystalline cellulose and mannitol for the diluent type, sodium starch glycolate and croscarmellose sodium for superdisintegrant type, and 2% and 10% for superdisintegrant concentration. Granulation with calcium carbonate (ratio of 1:8) was the taste-masking method of choice to be implemented. The formulated tablets results revealed that the manufacturing method has a significant influence on all the tested physicochemical properties (p-values < 0.05) such as tablet’s weight variation, hardness, friability, and disintegration time. Croscarmellose sodium obtained better results than sodium starch glycolate. Both fillers obtained good properties when implementing direct compression method with croscarmellose sodium concentration of 2%, or wet granulation method with croscarmellose sodium concentration of 10%. Drug release was also increased by increasing concentration of croscarmellose sodium. These findings represent an easy manufacturing procedure with relatively low-cost materials that can be implemented to formulate dispersible tablets of bitter tasting drugs that will enhance patient compliance and lead to faster onset of action.
本研究的目的是评估几种掩味技术的效果,并研究不同配方变量对以雷尼替丁为模型药物的分散片理化性质的影响。采用多种方法对雷尼替丁粉末进行味掩盖。采用因子设计(24)设计片剂配方。考察了制备方法、填料类型、超崩解剂类型和超崩解剂浓度四个因素。制备方法选择的水平为直接压缩和湿造粒,稀释型为微晶纤维素和甘露醇,超崩解型为乙醇酸淀粉钠和交联纤维素钠,超崩解浓度为2%和10%。用碳酸钙造粒(比例为1:8)是优选的掩味方法。结果表明,制备方法对片剂的重量变化、硬度、脆性、崩解时间等理化指标均有显著影响(p值< 0.05)。交联纤维素钠比乙醇酸淀粉钠效果更好。采用交联棉糖钠浓度为2%的直接压缩法和交联棉糖钠浓度为10%的湿造粒法,两种填料均获得了良好的性能。交联棉糖钠浓度的增加也促进了药物的释放。这些发现代表了一种简单的制造过程,使用相对低成本的材料,可以用于配制苦味药物的分散片,这将提高患者的依从性,并导致更快的起效。

Levels selected were direct compression and wet granulation for the manufacturing method, microcrystalline cellulose and mannitol for the diluent type, sodium starch glycolate and croscarmellose sodium for superdisintegrant type, and 2% and 10% for superdisintegrant concentration. Granulation with calcium carbonate (ratio of 1:8) was the taste-masking method of choice to be implemented. The formulated tablets results revealed that the manufacturing method has a significant influence on all the tested physicochemical properties (p-values < 0.05) such as tablet’s weight variation, hardness, friability, and disintegration time. Croscarmellose sodium obtained better results than sodium starch glycolate. Both fillers obtained good properties when implementing direct compression method with croscarmellose sodium concentration of 2%, or wet granulation method with croscarmellose sodium concentration of 10%. Drug release was also increased by increasing concentration of croscarmellose sodium. These findings represent an easy manufacturing procedure with relatively low-cost materials that can be implemented to formulate dispersible tablets of bitter tasting drugs that will enhance patient compliance and lead to faster onset of action.\u0000","PeriodicalId":15232,"journal":{"name":"Journal of Applied Pharmaceutical Research","volume":"17 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85563960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most popular and patient-friendly method of drug administration is often thought to be the oral route of administration. Compared to conventional release formulations, advancements in formulation technology, including modified release dosage forms or sustained release oral dosage forms, have been extensively accepted. A sustained release dosage form provides a prolonged release of the drug over an extended period, thereby giving better patient compliance and enhanced bioavailability. Sustain release systems are considered a wiser approach for drugs with short half-lives requiring repeated dosing. Sustained release drug delivery has a range of advantages over conventional dosage forms, including increased patient compliance due to less frequent drug administration, significantly reduced steady state drug level fluctuations, maximum drug utilization, the increased safety margin of potent drugs, lower healthcare costs due to improved therapy, and shorter treatment times. The present review focuses on design, fabrication, and various factors that influence the performance of sustained-release dosage forms.
通常认为口服给药是最流行和对患者最友好的给药方法。与传统的释放制剂相比,配方技术的进步,包括改性释放剂型或口服缓释剂型,已被广泛接受。缓释剂型在延长的时间内提供药物的延长释放,从而提供更好的患者依从性和增强的生物利用度。对于半衰期短、需要反复给药的药物,缓释系统被认为是一种更明智的方法。与传统剂型相比,缓释药物递送具有一系列优势,包括由于给药频率较低而提高患者依从性、显著减少稳态药物水平波动、最大限度地利用药物、增强强效药物的安全边际、改进治疗方法而降低医疗成本以及缩短治疗时间。本文综述了缓释剂型的设计、制备及影响其性能的各种因素。

Background: Laparoscopic cholecystectomy has emerged over the open cholecystectomy as gold standard for surgical treatment of symptomatic gall stones. Although pain after laparoscopic cholecystectomy is less intense, but many patients may experience considerable pain during first 24 hours in post-operative period. Intravenous (i.v.) use of dexmedetomidine in perioperative period lead to 90% decrease in the serum catecholamine levels, and further diminishing the haemodynamic response and sedating the patient and decrease analgesic requirements in the post-operative period. The efficacy of dexmedetomidine in providing hemodynamic stability during perioperative period and anesthesial recovery in patients undergoing laparoscopic cholecystectomy is studied. Methods: 60 patients of ASA grade I and II and of either sex (20–50 years) allocated in one of two parallel groups containing 30 patients each. In Group A- Dexmedetomidine (i.v.) bolus over 10min and continuous maintenance infusion 0.5µg/kg/h and in group B-0.9% normal saline i.v. bolus and continuous maintenance infusion was done. Parameters noted were heart rate, mean arterial pressure, oxygen saturation, post-operative pain were evaluated using VAS and analgesic requirement. Results: Both the groups were similar results in terms of age, sex, weight, ASA status, duration of surgery and hemodynamic parameters. SBP, DBP, MAP, SpCO2, EtCO2 values for both the groups were similar at all the intervals of time. No significant side effects were noted. Conclusion: Dexmedetomidine, pre-anaesthetic medication and its intraoperative infusion, further reducing the intraoperative anaesthetic requirement, sympathoadrenal response to intubation, maintains intraoperative cardiovascular stability, smooth extubation, sedation, and reduction in postoperative complications.
背景:腹腔镜胆囊切除术已取代开放胆囊切除术成为对症胆结石手术治疗的金标准。虽然腹腔镜胆囊切除术后的疼痛不那么强烈,但许多患者在术后最初24小时内可能会经历相当大的疼痛。围手术期静脉注射右美托咪定可使血清儿茶酚胺水平降低90%,进一步降低血流动力学反应,使患者镇静,减少术后镇痛需求。研究右美托咪定对腹腔镜胆囊切除术患者围手术期血流动力学稳定性及麻醉恢复的作用。方法:60例ASA I级和II级患者,性别不限(20-50岁),分为两个平行组,每组30例。A组右美托咪定(静脉滴注)10min,持续维持输注0.5µg/kg/h; b组0.9%生理盐水静脉滴注,持续维持输注。观察心率、平均动脉压、血氧饱和度、术后疼痛及镇痛需求。结果:两组在年龄、性别、体重、ASA状态、手术时间和血流动力学参数方面结果相似。两组的收缩压、舒张压、MAP、SpCO2、EtCO2值在各时间区间均相似。没有发现明显的副作用。结论:右美托咪定、麻醉前用药及其术中输注,进一步降低术中麻醉需求、交感肾上腺对插管的反应,维持术中心血管稳定、拔管顺畅、镇静,减少术后并发症。

Tablet is most popular among all dosage forms today because of its convenience, ease of administration, greater flexibility in dosage form design, ease of production, and low cost and non-invasive therapy. Formulation of tablets requires API along with excipients. Excipients include lubricants, diluents, binders, glidants, disintegrants, sweetening agents, flavoring agents, etc. Recent trends indicate that multi-particulate drug delivery systems are suitable for achieving extended-release oral formulation with a low risk of dose dumping, mixing flexibility to attain difference release patterns, and reproducible and short gastric residence time. Modern technology in immediate-release tablets, such as novel granulation techniques and electrostatic dry powder coating techniques, are prevalent nowadays. Recently, the immediate-release formulation has been similar to various sustained-release formulations that are currently readily attainable.
片剂是当今所有剂型中最受欢迎的,因为它方便,易于给药,剂型设计更大的灵活性,易于生产,低成本和非侵入性治疗。片剂的配方需要API和辅料。赋形剂包括润滑剂、稀释剂、粘合剂、柔滑剂、崩解剂、甜味剂、调味剂等。最近的趋势表明,多颗粒给药系统适合于实现口服缓释制剂,具有低剂量倾倒风险、混合灵活性以获得不同的释放模式、可重复性和短胃停留时间。新型造粒技术、静电干粉包衣技术等现代速释片剂技术正在蓬勃发展。最近,立即释放制剂已类似于各种缓释制剂,目前很容易获得。
