This disorder has triggered oxidative stress and excess free radicals condition. Smallanthus sonchifolius is a traditional medicine that acts as a diabetic therapy. This research aims to bring out the antidiabetic and antioxidant potential of S. sonchifolius extract (SSE). Materials and Methods: This study was conducted to measure the qualitative phytochemical identification, antioxidant and anti-diabetic activity of SSE. The antioxidant assay was carried out using 2,2-diphenyl-1-picrylhydrazine (DPPH)-scavenging activity, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS)-scavenging and hydrogen peroxide (H2O2)-reducing activity assays, ferric reducing antioxidant power (FRAP) potency, while anti-diabetic activity of SSE assay was carried out using inhibitory of α-amylase, α-glucosidase, and Glucose-6-Phosphatase (G-6-Pase). Results: SSE contained phenols, flavonoids, steroids/triterpenoids, saponins, tannins, and alkaloids. The antioxidant and antidiabetic activities of samples were calculated based on median inhibitory concentration (IC50). The IC50 values of SSE antioxidant, respectively, were DPPH (IC50 = 62.72 μg/mL), ABTS (IC50 = 61.03 μg/mL), H2O2 (IC50 = 438.36 μg/mL), the highest FRAP activity was 125.31 μM Fe(II)/μg extract at a concentration level of SSE 50 μg/mL. The IC50 values of SSE antidiabetic were α-amylase inhibition (IC50 = 37.86 μg/mL), α-glucosidase inhibition (IC50 = 90.41 μg/mL), and G-6-Pase inhibition (IC50 = 98.07 μg/mL), respectively. Conclusions: SSE has antidiabetic potential through antioxidant activities and α-glucosidase, α-amylase, and G-6-Pase inhibition activities.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46982238","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}

Materials and Methods: Dried ground leaves were subjected to a cold extraction method using an absolute concentration of methanol, ethanol, and water. Total phenolic, flavonoid, and proanthocyanidin content was estimated by using a linear regression equation from the calibration curve and expressed in terms of gallic acid equivalent (GAE) and rutin equivalent (RE). Antioxidant properties were determined using DPPH (1,1-diphenyl-2-picryl-hydrazyl), nitric oxide, and hydrogen peroxide assay, and their IC50 values were calculated. The antibacterial activity was tested using the agar well diffusion method against the common five pathogenic strains, and the zone of inhibition is compared with gentamicin (1 mg/mL) as a positive control. The minimum inhibitory concentration (MIC) value was obtained by the microbroth dilution method. The antidandruff assay was performed on Malassezia furfur by the disk diffusion method into Sabouraud dextrose agar overlaid with 1 mL of olive oil, and the MIC value was determined by the microtiter plate method. Results: The result showed that the Artemisia methanolic extract represents ample content of phenolics (248±3.29 mg/g of GAE), flavonoids (222.33±4.41 mg/g of RE), and proanthocyanidin (222.83±1.62 mg/g of RE equivalent). The antioxidant assay revealed that methanolic extract has the highest radical scavenging activity followed by aqueous extract and then ethanolic extract. The antibacterial activity of leaf extract shows MIC value ranging from 6 to 25 μg/mL against various human pathogenic bacteria. The antidandruff assay showed that MIC value of methanolic extract is lesser than that of ethanolic extract (350<400) mg/mL. Conclusion: The results concluded that leaf extract of A. indica contains phenolics, flavonoids, and proanthocyanidin and exhibits adequate antibacterial, antidandruff, and antioxidant activity.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47242364","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}

In this study, a novel nanosuspension formulation with an aqueous base was prepared and evaluated to overcome the discussed challenges. Materials and Methods: The nanosuspension formulation was characterized by size, zeta potential, morphology, and in vitro release. Seventy patients were subjected to use either 1 mL of nanosuspension or the commercial product twice daily for six months and were then examined for changes in hair follicle diameter and hair density within a 1 × 1-cm2 area of the scalp as the primary endpoints besides any adverse reaction manifestation as the secondary endpoint. Results: The nanosuspension formulation showed uniform morphology, 200-nm particle size, and suitable zeta potential that ensures the stability. The in vitro release study exhibited almost 90% release in the first 6 h. It was observed that there were no significant differences between the efficacy of aqueous-based topical 2% nanosuspension of minoxidil and the commercial product in the treatment of AGA (P > 0.05). However, the aqueous-based topical 2% nanosuspension formulation showed better safety and tolerability compared to the marketed profile. Conclusions: It could be concluded that aqueous-based topical 2% nanosuspension is a suitable form with enhanced patient compliance compared to commercially manufactured products.{Figure 6}","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46848129","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}

Materials and Methods: Transdermal patches of RPS were prepared using polymers such as hydroxyl propyl cellulose (HPC-EF), polyvinyl pyrrolidone K-30 (PVP K-30), and polyvinyl pyrrolidone K-90 (PVP K-90) as film formers, polyethylene glycol (PEG-400) as a plasticizer, and Tween-80 and azone as permeation enhancers. The solvent casting technique was employed to develop the patches using aluminum foil as the backing membrane. These patches were evaluated for compatibility using Fourier transform infrared (FTIR) spectrophotometry and for content by ultraviolet (UV) spectrophotometry besides physicochemical properties such as thickness, adhesion, moisture content, moisture loss, and folding endurance. The patches were tested for in vitro release in United States Pharmacopoeia (USP) dissolution apparatus V and ex vivo permeation across shed snake skin in vertical Franz diffusion cell (FDC). Results: The characteristic FTIR spectra of RPS were also evident in the spectra of the patches, indicating drug-excipient compatibility. In vitro drug release indicated that the release of the drug was maximum from patches composed of HPC-EF (60.08±1.04%), which was much higher when compared with patches made of PVP K-30 (47.53±0.40%) and PVP K-90 (42.84±0.74%). The ex vivo permeation studies suggested that about 116.79±1.99 µg/cm2 of the drug was permeated in 24 h from formulation patches composed of HPC-EF that resulted in flux of nearly 7.06 µg/cm2/h. Conclusion: The studies indicated that feasibility of transdermal delivery of rabeprazole as a patch of 16 cm2 is likely to suffice the therapeutic requirement.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70821726","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}

Aim: This study investigated the application of the fruit gum of Crysophyllum albidum (CFG) as a matrix former in the formulation of chlorpheniramine maleate and theophylline hydrochloride tablets. Materials and Methods: The gum was extracted using acetone and evaluated for flow, swelling, and hydration capacity. Effects of temperature on CFG and drug compatibility were evaluated using differential scanning calorimetry (DSC). Granules containing CFG at 10, 20, and 30% w/w were prepared using the wet granulation method and evaluated for flow properties. Compressed tablets were evaluated for uniformity of weight, hardness, friability, and drug content. In vitro drug release studies were carried out in simulated gastric (pH 1.2) and simulated intestinal (pH 6.8) fluids. Pearson’s similarity correlations were used to analyze results. Results: CFG had a swelling capacity of 22% and hydration capacity of 1.44 with an angle of repose of 30o and Carr’s index of 7.6 signifying good flow. DSC thermogram returned an endothermic glass transition peak at 72.1oC with no appreciable shifts in the peak when CFG was incorporated into the drug. Tablet hardness and friability were concentration dependent with values of 6.5–8.5kg F and 0.04–0.4%, respectively; drug content was within official specifications. Formulations containing 30%w/w CFG sustained drug release for over 12 h and showed better ability to control drug release than HPMC at same concentration.

The objective of this study was to prepare and evaluate the antibacterial effects of a pharmaceutical gel containing herbal extracts including Lawsonia inermis (henna) and Matricaria chamomilla. Using hydroxypropyl methylcellulose (HPMC), carboxymethylcellulose (CMC), and propylene glycol (PEG), the pharmaceutical gel was formulated and the physical properties of the formulation were specified at 37 ± 2°C. The total phenolic content (TPC) of extracts was determined using the Folin–Ciocalteu method and expressed as mg gallaic acid (GA) per gram extract (Ex). The release of the polyphenol compounds from the optimum formulation was investigated using the Franz cell device. Eventually, the disc diffusion method was used to evaluate the antibacterial activity of optimum formulation against the two pathogenic bacteria strains Staphylococcus aureus and Pseudomonas aeruginosa. The results showed that the optimum formulation was stable at least for 3 months. The TPC of the aqueous extract of henna leaves, the hydroalcoholic extract of chamomile flowers, and the optimum formulation was 57.8, 181.08, and 202.75 mg GA/g Ex, respectively. Nearly 80% of the phenolic compounds in the optimum formulation were released over 4 h. The phenolic compounds have inhibitory effects on the growth of S. aureus and P. aeruginosa. On the basis of this finding, the formulation had excellent stability, viscosity, homogeneity, extrudability, and antibacterial activity which can be employed as a topical pharmaceutical gel in cutaneous burn infection treatment.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43044269","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}
