Natural Gum

The utilization of natural gum polysaccharides as the vehicle for drug delivery systems and other biomedical applications has increased in recent decades. Their biocompatibility, biodegradability, and price are much cheaper than other materials. It is also renewable and available in massive amounts, which are the main reasons for its use in pharmaceutical applications. Gum can be easily functionalized with other natural polymers to enhance their applications. Various aspects of the utilization of natural gums in the forms of polyelectrolyte complexes (PECs) for drug delivery systems are discussed in this review. The application of different mathematical models were used to represent the drug release mechanisms from PECs; these models include a zero-order equation, first-order equation, Higuchi, simplified Higuchi, Korsmeyer–Peppas, and Peppas–Sahlin.

Natural polymers, particularly polysaccharide, have been used as drug delivery systems for a variety of therapeutic agents such as peptides, proteins, vaccines, DNA, and drugs for parenteral and non-parenteral administration. Chitosan, the second most abundant naturally occurring polysaccharide after cellulose, is a biocompatible and biodegradable mucoadhesive polymer that is extensively used in the preparation of nanoparticles (NPs). Chitosan NPs loaded with drugs were found to be stable, permeable and bioactive. In this review, the importance of chitosan and its derivatives in drug delivery is illustrated, different methods of preparation of chitosan and chitosan derivatives NPs and their physio- chemical properties are addressed. Moreover, the desirable characteristics of successful NPs based drug delivery systems, as well as the pharmaceutical applications of these NPs are also clearly explored.

Background: Rheumatoid arthritis (RA) is the most common occurring progressive, autoimmune disease, affecting 1% of the population and the ratio of affected women is three times as compared to men in most developing countries. Clinical manifestations of RA are the presence of anti-citrullinated protein antibody (ACPA) and rheumatoid factor (RF) in blood, tendered joints and soreness of the muscles. Some other factors which may lead to chronic inflammation are genetic and environmental factors as well as adaptive immune response. Several conventional drugs are available for the treatment of RA but have their own drawbacks which can be overcome by the use of novel drug delivery systems. : The objective of the present review is to focus on the molecular pathogenesis of the disease and its current conventional treatment with special reference to the role of novel drug delivery systems encapsulating anti rheumatic drugs and herbal drugs in passive and receptor mediated active targeting against RA. On reviewing the conventional and current therapeutics agains RA, we conclude that, although the current therapy for the treatment of RA is capable enough, yet more advances in the field of targeted drug delivery will sanguinely result in effective and appropriate treatment of this autoimmune disease.

: 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.

: The corona virus disease 2019 (COVID-19) has found its roots from Wuhan (China). COVID-19 is caused by a novel corona virus SARS-CoV2, previously named as 2019-nCoV. COVID-19 has spread across the globe and declared as pandemic by World health organization (WHO) on 11th March, 2020. Currently, there is no standard drug or vaccine available for the treatment, so repurposing of existing drugs is the only solution. Novel drug delivery systems (NDDS) will be boon for the repurposing of drugs. The role of various NDDS in repurposing of existing drugs for treatment of various viral diseases and their relevance in COVID-19 has discussed in this paper. It focuses on the currently ongoing research in the implementation of NDDS in COVID-19. Moreover it describes the role of NDDS in vaccine development for COVID-19. This paper also emphasizes how NDDS will help to develop the improved delivery systems (dosage forms) of existing therapeutic agents and also explore the new insights to find out the void spaces for a potential targeted delivery. So in these tough times, NDDS and nanotechnology can be a safeguard to humanity.

Background: Many efforts have been explored in the last decade to treat colon cancer but nanoparticulate drug delivery systems are making a vital contribution in the improvement of drug delivery to colon cancer cells. Objective: In this review, we attempt to highlight recent advancements in the development of novel drug delivery systems of nanoparticles for the targeted drug delivery to colon. Polymers like Epithelial Cell Adhesion Molecule (EpCAM) aptamer chitosan, Hyaluronic Acid (HA), Chitosan (CS)– Carboxymethyl Starch (CMS), silsesquioxane capped mesoporous silica, Near IR (NIR) fluorescent Human Serum Albumin (HAS), poly(ethylene glycol)-conjugated hyaluronic acid etc. have been discussed by employing various anticancer drugs like doxorubicin, oxaliplatin, paclitaxel, 5-fluorouracil etc. Conclusion: These novel drug delivery systems have been determined to be more efficacious in terms of stability, sustained and targeted drug delivery, therapeutic efficacy, improved bioavailability and enhanced anticancer activity.
