Coronavirus disease (COVID-19), an infectious disease caused by a novel coronavirus (2019-nCoV) or the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The infection began in bats and was communicated to people through yet obscure go-between creatures in Wuhan, Hubei territory, China, in December 2019. Its outbreak threatened the lives of many people throughout the world. There is no distinct treatment available yet, and is an urgent need to treat, prevent and eradicate this virus. Recently, numerous new technologies have been explored for the diagnosis, prevention, and treatment of viral infections. Among these, nanotechnology has emerged as a promising antiviral treatment, and currently, the development of COVID-19 drug delivery involving nanotechnology is under investigation. This review aimed towards the prospective treatment options integrating the ever-expanding field of nanotechnology against COVID-19. We focused on the current scenario in the developments of nanotechnology-based approaches because of the ongoing pandemic of COVID-19, the effectiveness of nanomaterials as vaccines, nanosensors as diagnostic or antiviral tools against coronaviruses, and post COVID-19 era has been discussed...

Oral Conventional dosage forms offer no control over the release of drug from the dosage form, which leads to variations in plasma drug levels; gastric emptying and gastric resident time are two another important factors that have a significant effect on the therapeutic efficacy of drug and it causes changes in the retention time of the drug. Accordingly, Floating microspheres is one of the most dependable and inventive techniques among all the gastro retentive drug delivery systems to overcome from these problems. Floating microspheres are mainly obtaining importance because of their vast suitability in the targeting of drugs to the stomach, undergo action and scattered uniformly over the gastric fluid to avoid the changes of gastric emptying and enlarge the liberation of the drug. This system also allows vastly in the fabrication of new controlled and delayed-release oral formulations, thus Expanding revolutions in pharmaceutical Expansion. The present review, in brief, says the physiology of the Intestinal gastric tract and elements governs the gastro retentive drug delivery system. This review...

The purpose of this research was to obtain directly compressible agglomerates of simvastatin using a crystallo-co-agglomeration technique and determine its in-vivo performance in rats. Simvastatin Dicalcium phosphate co agglomerates were prepared from Dichloromethane: Isopropyl Myristate: Distilled water system containing polyvinyl pyrrolidone (PVP). Dichloromethane acted as a good solvent for simvastatin, the water acted as a bad solvent, and isopropyl myristate acted as a bridging liquid for agglomeration. 23 factorial design was used for optimization, wherein the factors were stirring speed, polymer concentration, and amount of bridging liquid. The responses evaluated were dissolution, b value, and Carr’s index. The agglomerates were characterized by powder x-ray diffraction (PXRD), which showed that there is a decrease in crystallinity or partial amorphization of the drug in its agglomerated form. Micromeritic and compression properties of the agglomerates were affected by an incorporated polymer. Dissolution of agglomerates (91.73%) increased as compared to a pure drug (25.96%). The agglomeration increased the flow property of Simvastatin which was indicated by Carr’s index of a drug (40.81) and an...

The constant increase in the emergence of multidrug resistance among Staphylococcus aureus strains threatens public health. The study aimed at evaluating the anti-S. aureus activity, pharmacokinetic properties and interactions of compounds from Erianthemum dregei with proteins in S. aureus. Anti-S. aureus activity was investigated by broth dilution method while gas chromatography-mass spectrometry (GC-MS) was used to identify the compounds. The drug-likeness, pharmacokinetic and toxicity profiles of the compounds were predicted by SwissADME and PreADMET tools. AutoDock Vina was used to assessing the binding affinities of the docked ligand-receptor complexes. The extract revealed the minimum inhibitory concentration value of 0.78 mg/mL. Phytol (93.58%) and 3-tetradecyn-1-ol (6.42%) were the revealed constituents. In-silico predictions suggested both compounds to have drug-like properties as they adhered to the Lipinski’s rule of five. Phytol was found to have non-mutagenic effects, while 3-tetradecyn-1-ol was predicted to be mutagenic. The compounds were non-carcinogenic on mice model and carcinogenic on rat`s. Phytol has a binding affinity to DNA-gyrase and FtsZ with docking energy values of -4.1 and -5.3...

Osteoporosis is a condition that makes the bones porous, fragile, and prone to fractures. Although it is very prevalent in elderly people, it is more common in women, especially after menopause. The present study aimed to evaluate the effect of Asthiposhak Tablets on their anti-osteoporotic activity in ovariectomized (OVX) rats. Thirty-two female albino Wistar rats were randomly divided into four groups (n=8). Group 1 served as sham-operated control. Group 2 rats were ovariectomized (OVX) and served as a negative control. Group 3 received raloxifene (5.4 mg/kg i.p.) and served as the standard control, and Group 4 received Asthiposhak (405 mg/kg p.o.) and served as treatment control. After 60 days of ovariectomy, animals were treated with Asthiposhak for the next 45 days. At the end of the study, femur bone length, weight, bone ash calcium level, and bone mineral density (BMD) were estimated. The levels of serum alkaline phosphatase (ALP), calcium, and phosphorous, and bone histopathology were also evaluated. OVX-induced increased serum ALP, calcium, and phosphorous levels were significantly attenuated...
