The main purpose of the current research work is to enhance solubility and dissolution of BCS Class II drug, Flurbiprofen using liquid-solid compact technology. Flurbiprofen is a non-steroidal anti-inflammatory drug indicated for acute and chronic treatment of rheumatoid arthritis, osteoarthritis, and spondylytis. The rationale to select Flurbiprofen as the model drug is that it belongs to BCS Class II, having poor aqueous solubility of 10.45 ± 3.2μg/ml. Hence an attempt was made to enhance solubility, which may further increase the dissolution profile of the drug. In this regard, several liquisolid compact formulations were prepared for flurbiprofen and subjected to evaluation. They were prepared by using PEG 600 as a non-volatile solvent to dissolve the drug and further converted to freely flowing readily compressible powder using Avicel PH 102 as carrier material and Aerosil 200 as coating material. These liquisolid formulations were subjected to pre-compression rheological studies and post-compression evaluation parameters such as hardness, friability, weight variation, content uniformity, disintegration, and in-vitro dissolution. Results of dissolution profile of formulation TF3...

Forced degradation studies are a vital tool in pharmaceutical research and development to predict long-term stability. Stress studies should be performed in method development to know drug behavior but can also be performed with method validation for regulatory filling predict stability, and measure impurities. It is especially valuable when little data is free about potential degradation products. Forced degradation studies may help encourage drug advancement in regions like formulation development, manufacturing, and packaging, in which information on substance conduct can be utilized to improve a medication item. Hence it is important to realize the purity profile and conduct of a medication substance under various natural conditions. For stable formulation development, comprehension of synthetic conduct forced degradation pathways and degradants of drug substance and drug product is very important. Therefore, by using different regulatory guidelines in the present review paper, we described the broad overview of forced degradation studies by determining the system to perform stress studies & its methods for isolation and identification of...

To investigate the phytoconstituents and anticancer potential followed by apoptotic studies of H. undatus fruit extracts on HepG-2 cells. Qualitative phytochemical profiling and anti-proliferation activity of Aqueous, Chloroform, Ethyl acetate, Hexane, and Methanol extracts of dragon fruit pulp was carried out. Based on the results of anti-proliferation studies, methanol extract was taken further for apoptotic study by treating HepG-2 cells for nuclear staining using DAPI and GC-MS analysis to elucidate the presence of active compounds. Qualitative phytochemical analysis revealed the presence of carbohydrates, tannins, saponins, anthocyanin, quinones, cardiac glycosides, terpenoids, triterpenoids, phenols, acids, and steroids in aqueous fruit extract. Similarly, chloroform fruit extract showed the presence of carbohydrates, saponins, alkaloids, cardiac glycosides, triterpenoids, phenols, and coumarins. Likewise, Ethyl acetate fruit extract had carbohydrates, tannins, saponins, flavonoids, alkaloids, anthocyanin, cardiac glycosides, terpenoids, triterpenoids, acids, and steroids. In hexane fruit extract, carbohydrate, saponins, anthocyanin, quinones, phenols, and acids were present. But more phytocompouds such as carbohydrates, tannins, saponins, flavonoids, alkaloids, anthocyanin, cardiac glycosides, terpenoids, triterpenoids, phenols, acids, and steroids were found...

Quercetin (QCN) is a flavonoid available in fruits and vegetables, and it has shown several medicinal properties, including anticancer properties. However, the radiosensitizing properties of QCN on adenocarcinoma cells have not been greatly looked into yet. Thus in the present study, we investigate the effect QCN would have on the lung adenocarcinoma cell line NCI-H23 (H23) when QCN is combined with radiation. We checked for QCN’s effect on cell survival of H23 and the embryonic HEK293T cells. We checked the effect that QCN alone and QCN in combination with radiation would have on oxidative stress, metastatic proteins MMP-2 and p21, the expression of AKT1 and PTEN genes, and the apoptosis-associated genes in H23 cells. We observed that QCN alone and in combination with radiation lowered the cell survival of H23 cells while not affecting the cell survival of HEK293T cells. The QCN treated groups showed a spike in oxidative stress, lowering of the levels of MMP-2 and p21 proteins, up-regulation of PTEN gene and down-regulation of AKT1 gene expression,...

Malnutrition is a condition in which there is an imbalance in the proportion of essential nutrients that the body requires to stay healthy. The most prevalent form of malnutrition is micronutrient deficiency and of this iron deficiency anaemia is the most common type, affecting over 2 billion people worldwide. Micronutrients are a special class of vital ingredients that are required in minuscule quantities to perform a wide range of physiological functions. The current therapy for the treatment of Iron deficiency anaemia has many drawbacks like gastrointestinal side effects, erratic absorption of iron, etc. To overcome the above side effects, we tried to develop and evaluate a site-specific sustained-release combined drug delivery system of Iron and Folic acid. Iron as Ferrous ions is preferentially absorbed in the jejunum. To facilitate the absorption of iron, the gastro retentive multiunit particulate system (GRMUPs) was developed comprising Ferrous Ascorbate is a source of iron. Colon targeted tablet was developed for Folic acid to localize and maximize the absorption of Folic acid in the...
