The development of innovative drug delivery systems, versatile to different drug characteristics with better effectiveness and safety, has always been in high demand. Chitosan, an aminopolysaccharide, derived from natural chitin biomass, has received much attention as one of the emerging pharmaceutical excipients and drug delivery entities. Chitosan and its derivatives can be used for direct compression tablets, as disintegrant for controlled release or for improving dissolution. Chitosan has been reported for use in drug delivery system to produce drugs with enhanced muco-adhesiveness, permeation, absorption and bioavailability. Due to filmogenic and ionic properties of chitosan and its derivative(s), drug release mechanism using microsphere technology in hydrogel formulation is particularly relevant to pharmaceutical product development. This review highlights the suitability and future of chitosan in drug delivery with special attention to drug loading and release from chitosan based hydrogels. Extensive studies on the favorable non-toxicity, biocompatibility, biodegradability, solubility and molecular weight variation have made this polymer an attractive candidate for developing novel drug delivery systems including various advanced therapeutic applications such as gene delivery, DNA based drugs, organ specific drug carrier, cancer drug carrier, etc.

: As a unique and pleiotropic polymer, d-alpha-tocopheryl polyethylene glycol succinate (Tocophersolan) is a polymeric synthetic version of vitamin E. Tocophersolan has attracted enormous attention as a versatile excipient in different biomedical applications including drug delivery systems and nutraceuticals. The multiple inherent properties of Tocophersolan make it play flexible roles in drug delivery system design, including excipients with outstanding biocompatibility, solubilizer with the ability of promoting drug dissolution, drug permeation enhancer, P-glycoprotein inhibitor and anticancer compound. For these reasons, Tocophersolan has been widely used for improving the bioavailability of numerous pharmaceutical active ingredients. Tocophersolan has been approved by stringent regulatory authorities (such as US FDA, EMA, and PMDA) as a safe pharmaceutical excipient. In this review, we systematically curated current advances in nano-based delivery systems consisting of Tocophersolan with possibilities for futuristic applications in drug delivery, gene therapy, and nanotheranostic.

Diatom microalgae are the most outstanding natural source of porous silica. The diatom cell is enclosed in a three-dimensional (3-D) ordered nanopatterned silica cell wall, called frustule. The unique properties of the diatom frustule, including high specific surface area, thermal stability, biocompatibility, and tailorable surface chemistry, make diatoms really promising for biomedical applications. Moreover, they are easy to cultivate in an artificial environment and there is a large availability of diatom frustules as fossil material (diatomite) in several areas of the world. For all these reasons, diatoms are an intriguing alternative to synthetic materials for the development of low-cost drug delivery systems. This review article focuses on the possible use of diatom-derived silica as drug carrier systems. The functionalization strategies of diatom micro/nanoparticles for improving their biophysical properties, such as cellular internalization and drug loading/release kinetics, are described. In addition, the realization of hybrid diatom-based devices with advanced properties for theranostics and targeted or augmented drug delivery applications is also discussed.

В обзоре представлены современные данные о механизмах диагностики, планирования и оценки успешности терапии различных заболеваний с помощью экзосом, об использовании их как нанопереносчиков (т.е. нановезикул для эффективной доставки молекул). За последние годы разработано большое количество разных, в основном синтетических, систем доставки лекарственных средств, недостатками этих систем является плохая биосовместимость и органическая неспособность к высокоточной доставке загруженных веществ. По сравнению с синтетическими системами доставки лекарственных средств, экзосомы - вследствие своего естественного происхождения - могут обладать большими преимуществами, такими, как лучшая биосовместимость и повышенная устойчивость к разрушительному воздействию иммунной системы. Описана технология производства наноструктур, разработка и производство с помощью бионанотехнологий так называемых «полностью синтетических экзосомоподобных нановезикул», преимущества и недостатки этих методов. This review presents current data on mechanisms for diagnosis, planning, and evaluation of success in the treatment of various diseases using exosomes as nanocarriers (i.e., nanovesicles for efficient delivery of molecules). In recent years, a large number of different, mainly synthetic drug delivery systems has been developed. Disadvantages of these systems are poor biocompatibility and organic inability to deliver high-precision loaded substances. Compared with synthetic drug delivery systems, exosomes due to their natural origin may provide great advantages, such as better biocompatibility and increased resistance to detrimental effects of the immune system. This review describes in detail a technology of nanostructure production, the development and production of so-called fully synthetic exosome-like nanovesicles using bionanotechnology, and advantages and disadvantages of these methods.

Novel Drug Delivery Systems are one of the widely use delivery system in the presence scenario. Novel drug delivery system is a novel approach to drug delivery that addresses the limitations of the traditional drug delivery systems. In the form of a Novel Drug Delivery System an existing drug molecule can get a new life. The novel drug delivery system is Increases bioavailability and it Can be used for long-term treatments of chronic illness, Sustained maintenance of plasma drug levels as well as it Decreased adverse drug effects in the total amount of drugs required thus reducing side effects it Improved patient compliance due to reduction in number and frequency of doses required. There is less damage sustained by normal tissue due to targeted drug delivery. In this paper our main focus to give the throughout knowledge of some newer (Novel drug delivery system) to understand the concept of the Novel dossage form.

Abstract Since the second half of the 20th century, bioceramics are used for bone repair and regeneration. Inspired by bones and teeth, and aimed at mimicking their structure and composition, several artificial bioceramics were developed for biomedical applications. And nowadays, in the 21st century, with the increasing prominence of nanoscience and nanotechnology, certain bioceramics are being used to build smart drug delivery systems, among other applications. This minireview will mainly describe both tendencies through the research work carried out by the research team of María Vallet-Regí.
