The ophthalmic in-situ gels now days proved an palpable sustained drug delivery in various eye diseases. The formulation of in-situ gels for eye which carries the advantages like easy for administration, reduces frequency of dose and improves patient compliance. The formation of in-situ gels depends on phase transition system or sol-gel transition system. The formulation approaches like temperature intonation, pH change and presence of ions from which the drug gets released in a sustained and controlled manner are utilised for in-situ gels. Various polymers that are used for the formulation of in-situ gels include chitosan, Pluronic F-127, poly-caprolactone, gellan gum, alginic acid, xyloglucan, pectin...

The drug delivery technology landscape has become highly competitive and rapidly evolving. More and more developments in delivery systems are being integrated to optimize the efficacy and cost-effectiveness of the therapy. Conventional topical formulations are intended to work on the surface of the skin. Normally, upon application such formulations release their active ingredients and producing a highly concentrated layer of active ingredient that is quickly absorbed. Therefore, need exists for a system to increase the amount of time that an active ingredient is present either on skin surface as well as within the epidermis, at the same time, minimizing its transdermal penetration in the body. In recent times, microsponge delivery system (MDS) has been successively addressed for the controlled release of drugs onto the epidermis with assurance that the drug remains chiefly localized and does not enter the systemic circulation in major amounts. Drug loaded microsponge consist of microporous beads, typically 10-25 μm in diameter that possess a versatility to entrap wide range of active agents. Microsponge Systems are...

The gold standard in pharmaceutical industry is the oral delivery because it is the easiest, safest, economical and convenient method for the drug delivery. Mouth dissolving tablets have becomes the most demanding application during last decades and in the pharmaceutical industry this field has become a rapidly area. Mouth dissolving tablets during insertion in the mouth should have to dissolve or disintegrate in the mouth within 15sec to 3 minutes without the help or need of any drinking agent like water. These mouth dissolving tablets can be given anytime, anywhere to anyone who needs this without the presence of water and these will show the effective action in few...

Mitochondria are involved in different physiological and pathological processes that are crucial for tumor cell physiology, growth and survival and its dysfunction leads to many human abnormalities, including cardiovascular diseases, neurodegenerative diseases, autoimmune disorders and cancer. The present review is focused on the different experimental and therapeutic cancer strategies addressed to either target mitochondria directly, or use mitochondria as mediators of apoptosis, although its total molecular mechanism has not been elucidated. Therefore, the role of mitochondria in the etiology and progression of several function and explore potential therapeutic benefits of targeting mitochondria in the disease processes. Newly evolving advances in disease diagnostics and therapy will further facilitate future growth in the field of mitochondrian biology, where there is a dire need for sensitive and more affordable diagnostic tools and an urgency to develop effective therapies and identify reliable drug to predict accurately the response to a cancer therapy.These approaches to treat mitochondrial dysfunction rationally could lead to selective protection of cells in different tissues and various disease states. To...

Transdermal drug delivery system has been accepted as potential non-invasive route of drug administration, with advantages of prolonged therapeutic effect, reduced side effects, improved bioavailability, better patient compliance and easy termination of drug therapy. Non-steroidal anti-inflammatory drugs (NSAIDs) represents the most commonly used medications for the treatment of pain and inflammation, but numerous well-described side effects can limit their use. Therefore transdermal delivery of NSAIDs has advantages of avoiding hepatic first pass effect, gastric irritation and delivering the drug for extended period of time at a sustained level. The present article gives the brief view on the work been done on various NSAIDs by formulated and delivered as transdermal patches to decrease the side effects associated with the oral delivery. The various NSAIDs included in this article include Ketoprofen, Ibuprofen, Naproxen, Fluribrofen, Diclofenac, Aceclofenac, Ketorolac, Indomethacin, Meloxicam, Nimesulide, Celecoxib,...
