Lipid-based drug delivery systems in the form of triglyceride emulsions, micellar systems and liposomes have been used for parenteral administration for the last few decades. Large number of new chemical entities (NCE) presents formulation and bioavailability problems because of the dose and poor solubility in solvent and co-solvent systems. In addition, high drug concentrations can lead to irritation and pain at the site of injection. There is an increasing interest to expand the range of targetable lipid based systems to solubilize a wide variety of drugs, to improve stability, ease of processing and manufacture in a sterile form. New class of parenteral lipid based drug delivery system includes Tocol emulsions, solid lipid nanoparticles and nanosuspensions, sterically stabilized phospholipid micelles, lipid micro-bubbles and lipoprotein drug carriers. This review article covers the challenges faced by the formulation scientist at each stage of product development of lipid based drug delivery...

Transdermal drug delivery system (TDDS) in comparison to conventional system offers sustained drug release as well as decrease the intensity of action and decrease in the side effects associated with conventional therapy. Presently only about 40 products of more than 20 drug molecules are available in market. The barrier property of the stratum corneum is the main obstructer in the release of drug from the transdermal patch. Various approaches to overcome this barrier function of skin have been broadly studied. Innovations in technologies continue to occur at a positive rate, making the technology a productive and exciting area of innovation, research and product development. In this review, various new development in the field of TDDS are included which are intended to be a need base system. In this review, we have summarized various physical and chemical approaches for transdermal flux enhancement as well as the application of electricity, ultrasound, microneedle and chemical...

Over the past decades, herbal medicine has become a thing of global significance with medicinal and economic implications. Wide spread use of herbs throughout the globe has raised serious concerns over its quality, safety, and efficacy. Our investigation showed that these investigated medicinal plants could prevent ulcer in a dose-dependent manner. Histological studies revealed that these medicinal plants did not show any acute toxicity. Preliminary photochemical screening of this medicinal plant identified the presence of important secondary metabolites like flavonoids and tannins. A peptic ulcer in the stomach is called a gastric ulcer. One that is in the duodenum is called a duodenal ulcer. Peptic ulcers happen when the acids that help you digest food damage the walls of the stomach or duodenum. The most common cause is infection with a bacterium called Helicobacter pylori. Another cause is the long-term use of non-steroidal anti-inflammatory medicines (NSAIDs) such as aspirin and ibuprofen. Stress and spicy foods do not cause ulcers, but can make them worse. As many as 70-90% of...

Dillenia Indica, commonly known as elephant apple and locally known as outenga, is the handsome evergreen tree grows in the moist forest of sub-Himalayan region to Assam. The fruit grows in abundance and due to lack of knowledge and technical knowledge; most of these fruits are wasted. In Assam, traditionally the unripe fruits are used to make curries because of its sour taste and ripe fruits are making pickles. The fruits are generally high in fibre and due to presence of gummy substances, extraction of juice becomes difficult. The plant grows about 15 m tall. Not only the fruits have medicinal values but the leaves and the bark also showed numerous pharmacological activity. The studies showed that the plant possesses various activities like Antimicrobial, Antioxidant, Analgesic, Anti-inflammatory, dysentery, Antidiabetic etc. The fruits and the juice of the plant are traditionally used for the treatment of various diseases and one of the major diseases is Diabetes Mellitus. It was also proved from the review of literatures that this plant possesses...
