Objective: The present research work was to formulate optimize and evaluate hydrocortisone-loaded niosomal gel for the management of rheumatoid arthritis. Method: Niosomal gel was successfully prepared by lipid-thin film hydration process and optimized by using 23 full factorial designs using three independent variables (tween 80 concentration, cholesterol concentration, and sonication time) and three dependent variables (cumulative drug release, mean particle size and entrapment efficiency). The effect of all variables was assessed by response surface methodology. Results: The prepared formulations were evaluated in terms of particle size, in-vitro drug release, encapsulation efficiency, zeta potential, viscosity, and spreadability. Based on response surface methodology, S6 formulation was found to be the best formulation with entrapment efficiency of 92.27%, in-vitro drug release of 75.61% in 8 hrs, and mean particle diameter of 121.58 nm. The stability studies indicated that all the formulations are stable as none exhibited significant drug content change over time. Conclusion: The study indicated the successful development of hydrocortisone-loaded niosomal gels with improved penetration, good homogeneity, and enhancement of duration...

Statins are the first line of defense in the treatment of dyslipidemia and hypercholesterolemia illness. HMG-CoA reductase inhibitors or statins are the most widely prescribed drugs for persons at risk of cardiovascular disease. Cardiovascular disease (CVD) is the leading cause of death and a major cause of morbidity around the world. Statins have the same mechanism of action, but their chemical structures, pharmacokinetic profiles, and lipid-modifying potency differ. Triglycerides, cholesterol, and low-density lipoprotein (LDL) levels in the blood are all known risk factors for vascular disease, but statin drugs help to increase high-density lipoprotein (HDL) levels in our bloodstream. Some of the drugs utilized include rosuvastatin, atorvastatin, simvastatin, and pravastatin. According to clinical data, rosuvastatin is the most effective drug for decreasing low-density lipoprotein cholesterol and triglycerides, followed by atorvastatin, simvastatin and pravastatin. A brief review of the analytical methods developed from 2001-2021 for the estimation of Antilipidemic drugs has been discussed in the present study. This study will help the researchers to develop better methods for this class...

Tumor hypoxia is an important pathological condition that influences several signaling cascades in malignant cells, eventually leading to therapy resistance. Several natural bioflavonoids hold promise as anti-cancer agents. However, the effect of Quercetin on hypoxic pancreatic cancer cells is unknown. We analyze the effect of Quercetin on expression levels of metastatic markers HIF1α and E-cadherin under hypoxic conditions. Quercetin treatment was significantly correlated with reduced HIF1α expression levels and elevated E-cadherin levels. Our results suggest that Quercetin may alter E-cadherin levels by regulating HIF1α expression. Quercetin may inhibit pancreatic cancer cell metastasis by regulating metastasis genes in a hypoxic microenvironment and has pharmacological potential in aggressive pancreatic cancer...

Since ancient times, herbal medicines have been utilized globally to prevent and cure a wide range of medical disorders. Despite the fact that they are employed in many different medical systems, it remains a challenge to ensure their quality control, proper scientific validation and standardization. Systematic validation and scientific regulation of natural formulations are required for the future improvement of traditional systems of medicine. The herbal products produced with proper standardization and validation are often more efficient and have fewer adverse effects. In the present study, the stem bark of Ficus religiosa, stems of Tinospora cordifolia, leaves of Moringa olifera and roots of Boerhaevia diffusa have been selected. Due to pharmacological effects present in these plants, they are widely used in different traditional medicines. All the chosen plants are standardized by powder microscopy, physicochemical parameters, phytochemical screening, heavy metal testing etc. Comparative analysis of these parameters helped detect adulteration in each of these selected plants. Further, the comparative study of in-vitro antioxidant profiles of all these selected plants helped...

Presently, the surge in the consumption of herbal formulations is encouraged by several factors; the main factor is that they are relatively safe and effective. Plant extracts are considered an alternative source of synthetic drugs and are expected to produce promising results for treating several diseases. The present study aimed to formulate and evaluate antibacterial thermosensitive mucoadhesive gel containing Quercus infectoria gall extract and synthesize and characterize the silver nanoparticles by using Quercus infectoria gall extract. For extraction, water and ethanol were used as a solvent. The major constituents of the extract are tannic acid, gallic acid, ellagic acid, and these three constituted showed synergistic antibacterial activity. Formulated gel delivered the drug for more than 4 hr. The batch F5 optimized with good viscosity, spreadability and extrudability, mucoadhesive strength, release of drug is more, and the gel is stable; hence it is used for further evaluation like in-vitro skin irritation study and in-vitro antibacterial test. The formulated gel was not irritant and showed antibacterial activity greater than the marketed...
