Abstract
The aim of this review is to enumerate medicinal plants and their bioactive compounds that may become potential leads in the mitigation of oral submucous fibrosis (OSMF) in the forthcoming future. It is focused on pathophysiology, risk factors, current treatment regimen, potential plant leads, and future therapies for OSMF. Data were extracted from a vast literature survey by using SciFinder, Web of Science, Google Scholar, and PubMed search engines with relevant keywords. Upon literature survey, we found that the phytochemical 'arecoline' present in the areca nut is the main causative agent of OSMF condition. Currently, OSMF is treated by immunomodulatory and anti-inflammatory agents such as corticosteroids, enzymes (hyaluronidase, chymotrypsin, and collagenase), anti-inflammatory mediators (isoxsuprine and pentoxifylline), dietary supplements (vitamins, antioxidants, and micronutrients), and anti-fibrotic cytokines like interferon-gamma that provides short-term symptomatic relief to OSMF patients. However, some plant leads have been proven effective in alleviating symptoms and mitigating OSMF, which ultimately improves the quality of OSMF patients' life. We concluded that plant drugs like lycopene, curcumin, Aloe vera, colchicine, and Glycyrrhiza glabra are effective against OSMF in various in vitro and/or clinical studies and are being used by modern and traditional practitioners.

Abstract
One of the most frequent malignancies in the world is colon cancer. Both men and women are affected in the same way. The colon, which makes up the last part of the digestive system and is where water and minerals from food waste are absorbed, is vulnerable to cancer. The most suitable technique of drug administration is oral administration. Aqueous solubility is low in more than 40% of novel chemical entities, resulting in poor oral drug administration. In the formulation of oral medications, low inconsistent bioavailability is a major challenge. Increasing medication bioavailability is one of the most difficult aspects of pharmacological development. Self-nano-emulsifying drug delivery systems (SNEDDS) have been a potential platform for biopharmaceutical classification system class II and IV drugs for oral delivery. Enhanced bioavailability and solubility, control of toxicity, pharmacological effects, improved stability, improved tissue macrophage dispersion, prolonged delivery, and resistance to physical and chemical degradation are just a few benefits of SNEDDS for herbal drugs. To increase activity and address problems associated with herbal drugs, nanosized modern drug delivery technologies are expected to have a promising future. Improved patient compliance, fewer problems with liquid SNEDDS filled in capsules, and enhanced stability SNEDDS are all benefits of converting liquid SNEDDS to solid oral dosage forms or solid SNEDDS. SNEDDS differs from previous solubility augmentation methods due to its biodegradable components, simplicity of large-scale production, and range of drug-targeting possibilities.

Abstract
Diabetes mellitus is an irreversible, chronic metabolic disorder indicated by hyperglycemia. It is now considered a worldwide pandemic. T2DM, a spectrum of diseases initially caused by tissue insulin resistance and slowly developing to a state characterized by absolute loss of secretory action of the β cells of the pancreas, is thought to be caused by reduced insulin secretion, resistance to tissue activities of insulin, or a combination of both. Insulin secretagogues, biguanides, insulin sensitizers, alpha-glucosidase inhibitors, incretin mimetics, amylin antagonists, and sodium-glucose co-transporter-2 (SGLT2) inhibitors are the main medications used to treat T2DM. Several of these medication's traditional dosage forms have some disadvantages, including frequent dosing, a brief half-life, and limited absorption. Hence, attempts have been made to develop new drug delivery systems for oral antidiabetics to ameliorate the difficulties associated with conventional dosage forms. In comparison to traditional treatments, this review examines the utilization of various innovative therapies (such as microparticles, nanoparticles, liposomes, niosomes, phytosomes, and transdermal drug delivery systems) to improve the distribution of various oral hypoglycemic medications. In this review, we have also discussed some new promising candidates that have been approved recently by the US Food and Drug Administration for the treatment of T2DM, like semaglutide, tirzepatide, and ertugliflozin. They are used as a single therapy and also as combination therapy with drugs like metformin and sitagliptin.

Abstract
The oral route is the most preferred route for systemic and local drug delivery. However, the oral drug delivery system faces the harsh physiological and physicochemical environment of the gastrointestinal tract, which limits the bioavailability and targeted design of oral drug delivery system. Innovative pharmaceutical approaches including nanoparticulate formulations, biomimetic drug formulations, and microfabricated devices have been explored to optimize drug targeting and bioavailability. In this review, the anatomical factors, biochemical factors, and physiology factors that influence delivering drug via oral route are discussed and recent advance in conventional and novel oral drug delivery approaches for improving drug bioavailability and targeting ability are highlighted. We also address the challenges and opportunities of oral drug delivery systems in future.

Abstract
In the last couple of years, novel drug delivery systems (NDDS) have attracted much attention in the food and pharmaceutical industries. NDDS is a broad term that encompasses many dosage forms, one of which is osmotic pumps. Osmotic pumps are considered to be the most reliable source of controlled drug delivery, both in humans and in animals. These pumps are osmotically controlled and release active agents through osmotic pressure. To a large extent, drug release from such a system is independent of gastric fluids. Based on such unique properties and advantages, osmotic pumps have made their mark on the pharmaceutical industry. This review summarizes the available osmotic devices for implantation and osmotic tablets for oral administration.

Abstract
The natural bioactive or nutraceuticals exhibit several health benefits, including anti-inflammatory, anti-cancer, metal chelation, antiviral, and antimicrobial activity. The inherent limitation of nutraceuticals or bioactive ligand(s) in terms of poor pharmacokinetic and other physicochemical properties affects their overall therapeutic efficiency. The excess of iron in the physiological compartments and its varying dynamic oxidation state [Fe(II) and Fe(III)] precipitates various clinical conditions such as non-transferrin bound iron (NTBI), labile iron pool (LIP), ferroptosis, cancer, etc. Though several natural bioactive ligands are proposed to chelate iron, the efficiency of bioactive ligands is limited due to poor bioavailability, denticity, and other related physicochemical properties. The present review provides insight into the relevance of studying the dynamic oxidation state of iron(II) and iron(III) in the physiological compartments and its clinical significance for selecting diagnostics and therapeutic regimes. We suggested a three-pronged approach, i.e., diagnosis, selection of therapeutic regime (natural bioactive), and integration of novel drug delivery systems (NDDS) or nanotechnology-based principles. This systematic approach improves the overall therapeutic efficiency of natural iron chelators to manage iron overload-related clinical conditions.

Abstract
The Coronavirus disease 2019 (COVID-19) has found its roots from Wuhan (China). COVID-19 is caused by a novel coronavirus SARS-CoV2, previously named as 2019-nCoV. It has spread across the globe and was declared as a pandemic by the World Health Organization (WHO) on 11th March, 2020. Currently, there is no standard drug or vaccine available for the treatment, therefore, 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 the treatment of various viral diseases and their relevance in COVID-19 has been 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 potential targeted delivery. Therefore, in these tough times, NDDS and nanotechnology can be a safeguard to humanity.

Abstract
Nano-sized drug transporters have become an efficient approach with considerable commercial values. Nanomedicine is not only limited to drug delivery by means of different administration routes, such as intravenous, oral, transdermal, nasal, pulmonary, and more, but also has applications in a multitude of areas, such as a vaccine, antibacterial, diagnostics and imaging, and gene delivery. This review will focus on lipid nanosystems with a wide range of applications, taking into consideration their composition, properties, and physical parameters. However, designing suitable protocol for the physical evaluation of nanoparticles is still conflicting. The main obstacle is concerning the sensitivity, reproducibility, and reliability of the adopted methodology. Some important techniques are compared and discussed in this report. Particularly, a comparison between different techniques involved in (a) the morphologic characterization, such as Cryo-TEM, SEM, and X-ray; (b) the size measurement, such as dynamic light scattering, sedimentation field flow fractionation, and optical microscopy; and (c) surface properties, namely zeta potential measurement, is described. In addition, an amperometric tool in order to investigate antioxidant activity and the response of nanomaterials towards the skin membrane has been presented.

Abstract
Introduction: Diabetic retinopathy (DR) is associated with damage to the retinal blood vessels that lead eventually to vision loss. The existing treatments of DR are invasive, expensive, and cumbersome. To overcome challenges associated with existing therapies, various intraocular sustained release and novel drug delivery systems (NDDS) have been explored.Areas covered: The review discusses recently developed intraocular devices for sustained release of drugs as well as novel noninvasive drug delivery systems that have met a varying degree of success in local delivery of drugs to retinal circulation.Expert opinion: The intraocular devices have got very good success in providing sustained release of drugs in patients. The development of NDDS and their application through the ocular route has certainly provided an edge to treat DR over existing therapies such as anti-VEGF administration but their success rate is quite low. Moreover, most of them have proved to be effective only in animal models. In addition, the extent of targeting the drug to the retina still remains variable and unpredictable. The toxicity aspect of the NDDS has generally been neglected. In order to have successful commercialization of nanotechnology-based innovations well-designed clinical research studies need to be conducted to evaluate their clinical superiority over that of the existing formulations.

Abstract
Phytocompounds isolated from plants are well appraised for their broad pharmacological
propensities in several pathologies. One key benefit of phytoconstituents is their relatively low toxicity
and adverse effects. Nonetheless, poor solubility, permeation, and poor specificity at the target site
tend to hinder its therapeutic efficacy. Hence, novel technologies for drug delivery systems are being
developed via the use of various nanoformulation strategies to overcome these challenges and give uni-
form medication focusing at the dynamic site in desired concentration and improved therapeutic effi-
cacy. Such approaches comprise of novel drug delivery systems (NDDS). The utilisation of herbal
formulations for NDDS is more beneficial and advantageous as opposed to others. The utilisation of
ethosome, liposome, emulsion, phytosomes, microsphere, and strong lipid nanoparticles of herbal for-
mulation has improved the remedial impacts of plant extricates. With the utilisation of all these, di-
rected delivery of the formulation is accomplished, because of which the formulation exhibits impact
on the site, and its’ bioavailability is, likewise, expanded. With these novel medication conveyance
frameworks, the actives and concentrates, which are utilised as part of natural formulations, exhibit a
sustained release, enhancement in stability, improved therapeutic efficacy, and protection from toxici-
ty. The primary motivation behind creating alternative drug delivery technologies is to expand the
effectiveness of drug conveyance and safety in the process and give more comfort to the patient. In this
review, the importance of various phytocompounds in the delivery of drugs is highlighted as well as
their importance in reducing the risk or diseases.

Abstract
The management of breast cancer with advanced disease or metastasis is a common problem in India and other countries. A panel of 13 oncology experts deliberated on the sidelines of the 35th Indian Cooperative Oncology Network Conference held in Mumbai to formulate an expert opinion recommendation on the novel drug delivery system (NDDS) formulations in the treatment of metastatic breast cancer (MBC). The survey comprised of 39 questions related to limitations of conventional formulations and therapeutic positioning of NDDS formulations of docetaxel, paclitaxel and doxorubicin in the management of MBC. The experts used data from published literature and their practical experience to provide expert opinion and recommendations for use by the community oncologists. The experts opined that the newer NDDS formulations should provide a significant efficacy advantage in terms of overall survival and progression-free survival, or demonstrate better tolerability when compared with conventional formulations. The newer NDDS formulations of taxanes should be considered in special circumstances such as diabetes, in patients who have had hypersensitivity reactions and in cases where steroids need to be avoided. The novel formulations of doxorubicin should be used in the elderly and in patients with borderline cardiac function.

Abstract
Emergence of hyperlipidemia in urban population of India and the world at large is very high and accounts to several fatal diseases. This condition is known to manifest elevated levels of lipids and/or lipoproteins. Serious limitations like inadequate solubility, less absorption, less bioavailability, ineffectiveness in lowering of cholesterol levels, patient incompliance and so on are noticed with majority of anti-hyperlipidemic drugs and dosage forms, which are used conventionally. To overcome these shortcomings, building technology platforms for development of appropriate dosage forms is the need of the hour. These efforts are required to maximize patient acceptability while maintaining safety, efficacy, accessibility and affordability. Hyperlipidemia, its types, etiology, pathophysiology and conventional dosage forms are discussed here. The current approaches and novel developments which illustrate controlled drug release and sustained therapeutic effect along with site specific and target oriented drug delivery with better patient compliance are also reviewed critically. Despite the incentives provided by the efforts of formulation scientists, there is still a need for implementation of pharmaceutical technologies that enable to combat limitations of anti-hyperlipidemic drugs and conventional dosage forms associated with it. The present review emphasize on applications of novel drug delivery systems in pharmacotherapy of anti-hyperlipidemic drugs demonstrating the advantages and disadvantages.

Abstract
A novel carrier using chitosan nanoparticles entrapped into alginate microparticles is proposed for protecting molecules of interest from degradation in the digestive tract. The effects of polymer concentration, sonication, stirring, pH, and processing conditions on the physical characteristics of the carrier were studied. FITC and RBITC were used to localise the polymers within particles using CLSM. Diffusion of amaranth red (AR) from nanoparticles was quantified during dissolution under gastric and intestinal conditions. Under optimal preparation conditions, the size distribution of nanoparticles loaded with AR was uniform (690 nm) with an encapsulation efficacy of 21.9%. Alginate microparticles (285 µm) containing a homogenous distribution of nanoparticles and polymers were obtained. At gastric pH, the carrier released less than 5% of the loaded AR and, at intestinal pH, the release was rapid and complete. The drug carriers developed shows a promising use as a vehicle suitable to protect molecules of interest after oral administration.

Abstract
Novel drug delivery system is a novel approach to drug delivery that addresses the limitations of the traditional drug delivery systems. Our country has a vast knowledge base of Ayurveda whose potential is only being realized in the recent years. However, the drug delivery system used for administering the herbal medicine to the patient is traditional and out-of-date, resulting in reduced efficacy of the drug. If the novel drug delivery technology is applied in herbal medicine, it may help in increasing the efficacy and reducing the side effects of various herbal compounds and herbs. This is the basic idea behind incorporating novel method of drug delivery in herbal medicines. Thus it is important to integrate novel drug delivery system and Indian Ayurvedic medicines to combat more serious diseases. For a long time herbal medicines were not considered for development as novel formulations owing to lack of scientific justification and processing difficulties, such as standardization, extraction and identification of individual drug components in complex polyherbal systems. However, modern phytopharmaceutical research can solve the scientific needs (such as determination of pharmacokinetics, mechanism of action, site of action, accurate dose required etc.) of herbal medicines to be incorporated in novel drug delivery system, such as nanoparticles, microemulsions, matrix systems, solid dispersions, liposomes, solid lipid nanoparticles and so on. This article summarizes various drug delivery technologies, which can be used for herbal actives together with some examples.
