Captopril and telmisartan are widely used anti-hypertensive drugs, and their fixed dose combination is under phase IV trials. In the present study, spectrophotometry and RP-HPLC methods were successfully developed and validated per standard regulations. In UV spectrophotometry method concentrations of captopril and telmisartan in a synthetic mixture prepared in the laboratory were determined using the simultaneous equation method. The linearity was found 8 to 40 μg/mL for captopril and 5 to 25 μg/mL for telmisartan. The R2 (Coefficient of Correlation) value was found to be 0.999 for both drugs. The %assays of the conc. of captopril and telmisartan in synthetic mixture were found in an acceptable range. In the RP-HPLC method %assay was found to be 100.05 and 100.16% with %RSD value of 0.34 and 0.58 for captopril and telmisartan, respectively. The proposed UV and RP-HPLC method simultaneous estimation of captopril and telmisartan has potential application for qualitative identification as well as quantitative determination.

Objective: An ICH-compliant RP-HPLC approach was created and validated in order to measure the concentrations of HCTZ and LIS in bulk and mixed medicinal dosage forms. This procedure was subsequently submitted for certification. Methods: Column, a Phenomenex Luna C18(2) (250 x 4.6 mm, 5μ) with a Methanol: Formic acid (30:70) mobile phase, a flow rate is kept as 01 mL/min, the wavelength of detection was 215 nm, and a used detector was PDA. Results: Hydrochlorothiazide (HCTZ)) and lisinopril (LIS) both had linear calibration curves (r2 = 0.9973 and 0.9983, respectively) for the ranges of concentration 4.0 to 6.0 and 10.0 to 15.0 μg/mL. The proposed technique eluted LIS in 3.97 minutes and hydrochlorothiazide in 4.53 minutes. Lisinopril had a recovery rate of 99.31 to 99.83%, whereas hydrochlorothiazide had a recovery rate of 100.75 to 101.16%. At 1.22 and 0.31 μg/mL, respectively, HCTZ as well as LIS had the lowest detectable values. It was found that the LoQs for lisinopril and hydrochlorothiazide were 0.97 and 3.75 μg/mL, respectively. Conclusion: It was found that the current RP-HPLC technique is reliable, simple to use, accurate, linear, efficient, and rapid. With a shorter analysis period, this method offers better resolution between the two compounds. Therefore, there is sufficient evidence to include the approach in regular lisinopril and hydrochlorothiazide analysis in a variety of pharmaceutical companies and academic institutions.
目的：建立并验证了一种符合ICH的RP-HPLC方法，以测量散装和混合药物剂型中HCTZ和LIS的浓度。该程序随后提交认证。方法：采用Phenomenex Luna C18（2）（250 x 4.6 mm，5μ）柱，甲醇：甲酸（30:70）流动相，流速为01 mL/min，检测波长为215 nm，所用检测器为PDA。结果：氢氯噻嗪（HCTZ）和赖诺普利（LIS）在4.0～6.0和10.0～15.0μg/mL浓度范围内均具有线性校准曲线（r2分别为0.9973和0.9983）。所提出的技术在3.97分钟内洗脱LIS，在4.53分钟内洗脱氢氯噻嗪。赖诺普利的回收率为99.31至99.83%，氢氯噻嗪的回收率则为100.75至101.16%。在分别为1.22和0.31μg/mL时，HCTZ和LIS的检测值最低。研究发现，赖诺普利和氢氯噻嗪的LoQ分别为0.97和3.75μg/mL。结论：现有的RP-HPLC技术可靠、简便、准确、线性、高效、快速。由于分析周期较短，该方法在两种化合物之间提供了更好的分辨率。因此，有足够的证据将该方法纳入各种制药公司和学术机构的赖诺普利和氢氯噻嗪定期分析中。

Objective: The current study aimed to optimize the bioavailability and absorption of olmesartan in the lower gastrointestinal tract by creating a bilayer tablet for biphasic drug release. Methods: Microcrystalline cellulose was combined and direct compression the requirement for an early response to address an undesirable defect or condition. In the current instance, 5 mg of olmesartan must be released immediately, and the remaining 10 mg of olmesartan must be released gradually to maintain the therapeutic concentration. In order to adjust the release pattern of the olmesartan sustained release tablet in accordance with the needs of therapy and IP guidelines. Result: The best cumulative drug release was demonstrated by formulation. All formulations for immediate release support the first-order kinetics. As a result, all three formulations were chosen for additional research. Dissolution rate for long-term release Cumulative drug release from the SR1 to SR3 formulations using HPMC K15M and gum acacia was up to 24 hours. Utilizing HPMC K15M and guar gum, the formulations SR1, SR2, and SR3 demonstrated cumulative drug releases of 72.66, 69.19, and 92.66%, respectively. The best cumulative release of the drug was demonstrated by formulations SR1, SR2, and SR3. Consequently, everyone was chosen for additional research. The cumulative drug release for the IR1-SR1, IR2-SR2, and IR3-SR3 bilayer tablet formulations was 95.24, 90.15, and 91.09%. Up to 12 hours of cumulative drug release from the formulation was observed. As a result, it was determined that IR1-SR1 was the best formulation out of all of them due to its strong correlation between the total cumulative percentage of medication releases and time, which was 95.24% up to 12 hours.

This study aimed to develop a straightforward, sensitive, exact, quick, and accurate reverse phase high performance liquid chromatography (RP-HPLC) method for figuring out how much lisinopril is in pharmaceutical gels and other large amounts of medication. Agilent Zorbax Bonus-RP column (250 x 4.6 mm, 5μ) was used for the chromatographic separation. “A mobile phase composed of methanol and trifluoroacetic acid (50:50 v/v) was used to develop the analytical procedure. The flow was found to be occurring at a rate of 1-mL/min and with a wavelength of 215 nm. The retention time was 2.28 min. In a concentration range from 3–7 μg/mL (r2=0.998), the drug’s response was determined to be linear. The LoQ was 1.11 μg/mL, while the LoD was 0.36 μg/mL. Lisinopril’s %assay was determined to be 98.22%, while assays for the other medicines in the commercial formulation showed no interference from the excipients. This method functions well and can be applied to routine analysis.

Aim: The current research aims to create a high-resolution and validated liquid chromatographic method used for quantitative detection of etoricoxib within dosage forms that is both easy to use and reliable in terms of accuracy, sensitivity, and reproducibility. Materials and Methods: Analysis was carried out at isocratic conditions at flow rate of 0.7 mL/min using a mobile phase consisting of 40 parts methanol to 60 parts water (0.1% OPA) at pH 3.2. The eluents were tested using UV detection at 236 nm. Results: Etoricoxib had clearly separated peaks with a retention duration of 4.347 minutes in the optimized settings. The concentration range used to generate the calibration curve was 10 to 60 μg/mL. LoD was 0.0779 μg/mL, and upper LoQ was 0.23 μg/mL. The approach has been effective in separating a known quantity of etoricoxib, and the percentage of degradation was shown to be very low across all stress settings. Conclusion: Etoricoxib in bulk drug and commercial formulations can be identified and quantified using the proposed method, which has been validated in accordance with ICH recommendations.

A fundamental source of food and medicine for nearby Himalayan populations is the diversity of plants. The percentage yield of extract, phytochemicals, and minimum inhibitory concentration (MIC) for the extracts Euterpe oleraceae, Vaccinium myrtillu, Phyllanthus embilica, Rubus ellipticus, and Rubus niveus were determined. The clinical and laboratory standards Institute’s micro broth dilution method was used to assess these extracts’ antimicrobial effects on Klebsiella pneumoniae and Pseudomonas aeruginosa, while the purification of the positive extract was done by high-pressure liquid chromatography. Phytochemical analysis was done to determine the secondary plant metabolites, including alkaloids, polyphenols, glycosides, tannins, flavonoids, carbohydrates, steroids, and saponins. All five of the studied plants’ extracts showed antibacterial activity against one or more tested microorganisms. Several phenolic acids (chlorogenic acid, salicylic acid, ellagic acid, ferulic acid, gallic acid, and caffeic acid were detected in all extracts. The R. ellipticus extracts with petroleum ether, chloroform, methanol, and water show a maximum yield between (64–56%) except R. ellipticus extract with hexane (25.82%) showed a low yield. All the extracts have major quantities of carbohydrates, flavonoids, and phenols. These results suggested that produced antimicrobial activity was due to the presence of phytoconstituents in all extracts.

Thrombosis is possible outcomes of excessive coagulation or inhibition of anticoagulant processes. The pathophysiology of thrombosis is primarily caused by irregularities of the vascular wall, changes in blood flow, and changes in blood composition. Now a day’s, various natural antithrombotic or thrombolytic medications are used for the treatment. This study evaluated the pharmacognostical, antithrombin and thrombolytic activity of leaves extract of plant Lantana camara. The extractive value of leaves extract of plant L. camara was higher (20.58%) in methylene chloride as solvent. Total ash of plant L. camara was about 9.00% w/w. In comparison with heparin L. camara extract shown 50.10, 60.23, 62.32, 68.48 and 71.32% antithrombin activity at 10, 20, 40, 60, 80 and 100 mg/mL concentration, respectively. When different extract concentrations were added in the tubes containing blood clots, L. camara showed a good thrombolytic activity. We conclude that the leaves extract of plant L. camara shows significant antithrombin and thrombolytic activity.

Background and Objectives: Econazole nitrate (ECN) loaded nanoparticles with topical administration were the focus of the current study, which aimed to improve the topical efficacy of the medicine in treating fungal infections while also mitigating the drug’s gastrointestinal (GI) side effects. Further colloidal carrier methodology was employed as a method for the topical administration of medications with precision. Method: The emulsification-diffusion (E-D) method is an alternate approach for preparing nanogels that avoids the toxicitysolvent issues associated with the emulsification-evaporation technique. Its ease of use, enhanced stability, and adaptability have all been verified by a variety of research groups. ECN loaded with dichloromethane in stabilizer solution, formulated by high-speed homogenization at elevated pressure. The addition of aqueous phase with repeated homogenization cycles causes drug diffusion into nanogels. Further addition of mannitol as cryoprotectant and Carbapol 940 as gelling agent stabiles the formulation. Results: The typical size of the particles, polydispersity index (PDI), and zeta potential were all measured with the use of the Malvern zetasizer. Of the five NFs, the lyophilized batch of NF3 exhibited the lowest zeta potential (-11.6 mV) and the PDI (0.208), indicating that the composition was stable. DSC and XRD analysis revealed an amorphous transformation of ECN. The scanning electron micrograph demonstrated discrete, roundish particles. The existence, viscosity, and spreading ability of a gelled dispersion of the selected NLCs were evaluated. Total od 77% of the medication was released in-vitro from a chosen formulation of ECN-loaded nanogels. As a result, it is reasonable to assume that ECN-loaded nanogels are an effective drug delivery system for treating fungal infections since they prolong the duration of drug release. Conclusion: Under degraded conditions, there are not any peaks that conflict with one another. As a result, a technique was developed that is highly applicable due to its sensitivity, strength, accuracy, and demonstration of stability.

As a result, it is reasonable to assume that ECN-loaded nanogels are an effective drug delivery system for treating fungal infections since they prolong the duration of drug release. Conclusion: Under degraded conditions, there are not any peaks that conflict with one another. As a result, a technique was developed that is highly applicable due to its sensitivity, strength, accuracy, and demonstration of stability.","PeriodicalId":14260,"journal":{"name":"International Journal of Pharmaceutical Quality Assurance","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44393468","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}

Background: Since May 2022, that has been largest-ever spread of monkeypox in countries where it is not normally found. Since India is home to about 36% of the world’s population, an MPXV outbreak there might have far-reaching consequences. A fuller understanding of the monkeypox virus and the epidemiology of the disease is urgently needed to help clinicians, public health professionals, and politicians be prepared for any eventuality, especially given the speed with which it has spread to non-endemic nations. Aim: Review provides an overview of the epidemiology, clinical characteristics, treatments, vaccinations, and herbal resources used in the management of infection for the monkeypox disease. Immune-compromised host & group require to be given additional notice as the illness is known to have significant effects on pregnant women; we have also highlighted relevant information about such pathophysiological situations in this work. Result and conclusion: The spread of monkeypox virus (2022) in non-endemic nations could provide India with an opportunity to investigate the Krimighna medications mentioned in Brihatrayee, i.e.Charak Samhita, Sushruta Samhita and Ashtanga Hridaya with antiviral activity and to develop novel and useful antiviral agents to combat the monkeypox menace effectively.

Diabetes is a substantially growing unhealthiest in the globe that causes severe morbidity and mortality. Currently a day’s there’s an imperative for the invention, development and improvement of novel antidiabetic drug molecules. A chain of compound (5-imidazol-2-yl-4-phenylpyrimidin-2-yl) [2-(2- pyridyl amino) ethyl] amine were developed and synthesized by using suitable chemical synthetic techniques. These recently synthesized derivatives were characterized with the help of modern analytical techniques. This compound was evaluated for glycogen synthase kinase-3 enzyme inhibitor activities for managing of polygenic disease. GSK-3 inhibitors may advance and emerge as a novel strategy for the management of diabetes.
