Oral drug delivery remains the preferred route of drug delivery. Novel technologies with improved performance, patient compliance, and enhanced quality have emerged in the recent past. The fast dissolving drug delivery system started gaining popularity and acceptance as a new drug delivery system because they are easy to administer and lead to better patient compliance. Fast dissolving drug delivery system can be obtained by the various techniques i.e. direct compression, tablet molding, freeze drying, spray drying nanonization. Oral fast-dissolving tablets, are an examples of a few existing technologieswith the potential to accommodate various physicochemical, pharmacokinetic and pharmacodynamic characteristic of...

The benefits of Probiotics have been recognized and explored for over a century. Probiotics consist of bacteria or yeasts and can be considered functional foods that can re-colonize and restore the microflora symbiosis of the intestinal tract. Several health benefits associated with the Probiotics in various diseases includes Inflammatory Bowel Disease (IBD), Colon Cancer, Rotavirus-associated diarhoea, H.Pylori infection and Liver disease etc. Prebiotics are “non-digestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon”. Dietary modulation of the gut microflora by Prebiotics is designed to improve health by stimulating numbers and/or activities of Probiotics like Bifidobacteria and Lactobacill.This review also discuss the results of randomized controlled clinical trials that used Prebiotics to treat IBD, Hypertension, Colon Cancer, Diabetes and Hepatic Encephalopathy as well as their potential applications. The combination of Probiotics and Prebiotics is known as Synbiotics. Recently Synbiotics have been proposed as a new therapeutic option in Pediatric surgery, Digestive organ surgery,...

Ferulic acid (4-hydroxy-3-methoxycinnamic acid) is an phenolic compound and an antioxidant found in many staple foods, such as fruits, vegetables, cereals, coffee and in plant constituent exhibiting a wide range of therapeutic effects such as anticancer, antidiabetic, cardio protective and neuroprotective, anti-inflammatory activity. The present review summarizes the most recent literature on FA including its pharmacological actions, preclinical and clinical studies, reported mechanisms of actions, pharmacokinetic profile, precautions and safety parameters and its interaction with other drugs and plasma protein. The article also deals with the latest research updates as well as avenues for further research to elucidate the positive effects of this widespread phenolic compound for a better understanding of its potential applications in health and disease. It may subsequently help in the development and design of suitable pharmaco-active...

Drug resistant bacteria have been posing a major challenge to the effective control of bacterial infections for quite some time. One of the main causes of antibiotics drug resistance is antibiotic overuse, abuse, and in some cases, misuse, due to incorrect diagnosis. Bacterial antibiotic resistance is a significant issues faced by various industries, including the food and agricultural industries, the medical and veterinary profession and others. The potential for transfer of antibiotics resistance, or of potentially lethal antibiotic resistant bacteria, for example from a food animal to human consumer, is of particular concern. A method of controlling development and spread of antibiotic-resistant bacteria include changes in antibiotic usage and pattern of usage of different antibiotics. However, the ability of bacteria to adapt to antibiotic usage and to acquire resistance to existing and new antibiotics usage overcomes such conventional measures, and requires the continued development of alternative means of control of antibiotic resistance bacteria. Alternative means for overcoming the tendency of bacteria to acquire resistance to antibiotic control measures have...

Nanobiopharmaceutics involves delivery of biopharmaceutical product through different biomaterials like multifunctional nanoparticles, quantum dots, aquasomes, superparamagnetic iron oxide crystals, and liposomes dendrimers. Nanotechnology has emerged fields of biomedical research in the last few decades the presents context is an attempt to present the brief information about nanobiotechnological applications. Aquasomes are nanoparticulate carrier system but instead of being simple nanoparticles these arse three layered self assembled structures, comprised of a solid phase nanocrystalline core coated with oligomeric film to which biochemically active molecules are adsorbed with or without modification. Aquasomes are spherical 60–300 nm particles used for drug and antigen delivery. Aquasomes discovery comprises a principle from microbiology, food chemistry, biophysics and many discoveries including solid phase synthesis, supramolecular chemistry, molecular shape change and self assembly. Three types of core materials are mainly used for producing aquasomes: tin oxide, nanocrystalline carbon ceramics (diamonds) and brushite (calcium phosphate dihydrate). Calcium phosphate is the core of interest, owing to its natural presence in the body. The brushite is unstable and converts to...
