RESUMO

Primaquine (PQ) is a widely used antimalarial drug, but its high dosage requirements can lead to significant tissue damage and adverse gastrointestinal and hematological effects. Recent studies have shown that nanoformulations can enhance the bioavailability of pharmaceuticals, thereby increasing efficacy, reducing dosing frequency, and minimizing toxicity. In this study, PQ-loaded PLGA nanoparticles (PQ-NPs) were prepared using a modified double emulsion solvent evaporation technique (w/o/w). The PQ-NPs exhibited a mean particle size of 228 ± 2.6 nm, a zeta potential of +27.4 mV, and an encapsulation efficiency of 81.3 ± 3.5%. Scanning electron microscopy (SEM) confirmed their spherical morphology, and the in vitro release profile demonstrated continuous drug release over 72 h. Differential scanning calorimetry (DSC) thermograms indicated that the drug was present in the nanoparticles, with improved physical stability. Fourier-transform infrared spectroscopy (FTIR) analysis showed no interactions between the various substances in the NPs. In vivo studies in Swiss albino mice infected with Plasmodium berghei revealed that the nanoformulated PQ was 20% more effective than the standard oral dose. Biodistribution studies indicated that 80% of the NPs accumulated in the liver, highlighting their potential for targeted drug delivery. This research demonstrates the successful development of a nanomedicine delivery system for antimalarial drugs, offering a promising strategy to enhance treatment efficacy while reducing adverse effects.

RESUMO

Preclinical and clinical studies have demonstrated that precision therapy has a broad variety of treatment applications, making it an interesting research topic with exciting potential in numerous sectors. However, major obstacles, such as inefficient and unsafe delivery systems and severe side effects, have impeded the widespread use of precision medicine. The purpose of drug delivery systems (DDSs) is to regulate the time and place of drug release and action. They aid in enhancing the equilibrium between medicinal efficacy on target and hazardous side effects off target. One promising approach is biomaterial-assisted biotherapy, which takes advantage of biomaterials' special capabilities, such as high biocompatibility and bioactive characteristics. When administered via different routes, drug molecules deal with biological barriers; DDSs help them overcome these hurdles. With their adaptable features and ample packing capacity, biomaterial-based delivery systems allow for the targeted, localised, and prolonged release of medications. Additionally, they are being investigated more and more for the purpose of controlling the interface between the host tissue and implanted biomedical materials. This review discusses innovative nanoparticle designs for precision and non-personalised applications to improve precision therapies. We prioritised nanoparticle design trends that address heterogeneous delivery barriers, because we believe intelligent nanoparticle design can improve patient outcomes by enabling precision designs and improving general delivery efficacy. We additionally reviewed the most recent literature on biomaterials used in biotherapy and vaccine development, covering drug delivery, stem cell therapy, gene therapy, and other similar fields; we have also addressed the difficulties and future potential of biomaterial-assisted biotherapies.

RESUMO

Since the earliest days, people have been employing herbal treatments extensively around the world. The development of phytochemical and phytopharmacological sciences has made it possible to understand the chemical composition and biological properties of a number of medicinal plant products. Due to certain challenges like large molecular weight and low bioavailability, some components of herbal extracts are not utilized for therapeutic purposes. It has been suggested that herbal medicine and nanotechnology can be combined to enhance the benefits of plant extracts by lowering dosage requirements and adverse effects and increasing therapeutic activity. Using nanotechnology, the active ingredient can be delivered in an adequate concentration and transported to the targeted site of action. Conventional therapy does not fulfill these requirements. This review focuses on different skin diseases and nanotechnology-based herbal medicines that have been utilized to treat them.

RESUMO

Pain and swelling in the joints, increased synovial thickness, and bone and cartilage degeneration are all symptoms of Rheumatoid Arthritis (RA). Anti-rheumatic medications, which are used in conventional treatment plans for RA, need high doses, frequent administration, and long-term use, all of which increase the risk of major adverse effects and low patient compliance. Drug Delivery Systems (DDS) have been developed for RA treatment in an effort to avoid these obstacles and improve clinical efficacy. There have been many successful experimental RA models using these techniques. There has been a notable uptick in the study of RA nanotherapies as a prospective improvement over conventional systemic therapy. In order to overcome the limits of traditional treatments, researchers have begun looking into nanotherapeutic approaches, notably drug-delivery nanosystems. The precise delivery and concentration of therapeutic drugs in the affected regions are made possible by the passive or active targeting of systemic administration. Several new DDS for treating RA have been addressed here. Therefore, nanoscale drug delivery devices increase drug solubility and bioavailability while decreasing the need for higher doses.

RESUMO

Colorectal cancer (CRC) is a complex and multifactorial disorder in middle-aged people. Several modern medicines are available for treating and preventing it. However, their therapeutic uses are limited due to drawbacks, such as gastric perforation, diarrhea, intestinal bleeding, abdominal cramps, hair loss, nausea, vomiting, weight loss, and adverse reactions. Hence, there is a continuous quest for safe and effective medicines to manage human health problems, like CRC. In this context, herbal medicines are considered an alternative disease control system. It has become popular in countries, like American, European, and Asian, due to its safety and effectiveness, which has been practiced for 1000 years. During the last few decades, herbal medicines have been widely explored through multidisciplinary fields for getting active compounds against human diseases. Several herbal bioactives, like curcumin, glycyrrhizin, paclitaxel, chlorogenic acid, gallic acid, catechin, berberine, ursolic acid, betulinic acid, chrysin, resveratrol, quercetin, etc., have been found to be effective against CRC. However, their pharmacological applications are limited due to low bioavailability and therapeutic efficacy apart from their several health benefits. An effective delivery system is required to increase their bioavailability and efficacy. Therefore, targeted novel drug delivery approaches are promising for improving these substances' solubility, bioavailability, and therapeutic effects. Novel carrier systems, such as liposomes, nanoparticles, micelles, microspheres, dendrimers, microbeads, and hydrogels, are promising for delivering poorly soluble drugs to the target site, i.e., the colon. Thus, the present review is focused on the pathophysiology, molecular pathways, and diagnostic and treatment approaches for CRC. Moreover, an emphasis has been laid especially on herbal bioactive-based novel delivery systems and their clinical updates.

RESUMO

SARS-CoV-2 is a highly contagious and transmissible viral infection that first emerged in 2019 and since then has sparked an epidemic of severe respiratory problems identified as "coronavirus disease 2019" (COVID-19) that causes a hazard to human life and safety. The virus developed mainly from bats. The current epidemic has presented a significant warning to life across the world by showing mutation. There are different tests available for testing Coronavirus, and RT-PCR is the best, giving more accurate results, but it is also time-consuming. There are different options available for treating n-CoV-19, which include medications such as Remdesivir, corticosteroids, plasma therapy, Dexamethasone therapy, etc. The development of vaccines such as BNT126b2, ChAdOX1, mRNA-1273 and BBIBP-CorV has provided great relief in dealing with the virus as they decreased the mortality rate. BNT126b2 and ChAdOX1 are two n-CoV vaccines found to be most effective in controlling the spread of infection. In the future, nanotechnology-based vaccines and immune engineering techniques can be helpful for further research on Coronavirus and treatment of this deadly virus. The existing knowledge about the existence of SARS-CoV-2, along with its variants, is summarized in this review. This review, based on recently published findings, presents the core genetics of COVID-19, including heritable characteristics, pathogenesis, immunological biomarkers, treatment options and clinical updates on the virus, along with patents.

RESUMO

Allergic rhinitis (AR) is an IgE-mediated atopic disease that occurs due to inhaled antigens in the immediate phase. Misdiagnosis, insufficient treatment, or no treatment at all are frequent problems associated with the widespread condition known as chronic allergic rhinitis. AR symptoms include runny, itchy, stuffy, and sneezing noses. Asthma and nasal polyps, for example, sometimes occur simultaneously in patients. In order for people living with AR to be as comfortable and productive as possible, treatment should center on reducing their symptoms. The online sources and literature, such as Pubmed, ScienceDirect, and Medline, were reviewed to gather information regarding therapeutic modalities of AR and evidence-based treatments for the disease as the objectives of the present study. An increasing number of people are suffering from AR, resulting in a heavy financial and medical burden on healthcare systems around the world. Undertreating AR frequently results in a decline in quality of life. Treatment compliance is a critical challenge in the administration of AR. Innovative therapies are needed for RA to provide patients with symptom alleviation that is less expensive, more effective, and longer duration of action. Evidence-based guidelines are helpful for managing AR illness. Treating AR according to evidence-based standards can help in disease management. AR treatment includes allergen avoidance, drug therapy, immunotherapy, patient education, and follow-up. However, AR treatment with intranasal corticosteroids is more popular. Hence, in this review article, treatment options for AR are discussed in depth. We also discussed the incidence, causes, and new treatments for this clinical condition.

RESUMO

Among the primary causes of mortality in today's world is cancer. Many drugs are employed to give lengthy and severe chemotherapy and radiation therapy, like nitrosoureas (Cisplatin, Oxaliplatin), Antimetabolites (5-fluorouracil, Methotrexate), Topoisomerase inhibitors (Etoposide), Mitotic inhibitors (Doxorubicin); such treatment is associated with significant adverse effects. Antitumor antibiotics have side effects similar to chemotherapy and radiotherapy. Selenium (Se) is an essential trace element for humans and animals, and additional Se supplementation is required, particularly for individuals deficient in Se. Due to its unique features and high bioactivities, selenium nanoparticles (SeNPs), which act as a supplement to counter Se deficiency, have recently gained worldwide attention. This study presented a safer and more economical way of preparing stable SeNPs. The researcher has assessed the antiproliferative efficiency of SeNPs-based paclitaxel delivery systems against tumor cells in vitro with relevant mechanistic visualization. SeNPs stabilized by Pluronic F-127 were synthesized and studied. The significant properties and biological activities of PTX-loaded SeNPs on cancer cells from the lungs, breasts, cervical, and colons. In one study, SeNPs were formulated using chitosan (CTS) polymer and then incorporated into CTS/citrate gel, resulting in a SeNPs-loaded chitosan/citrate complex; in another study, CTS was used in the synthesis of SeNPs and then situated into CTS/citrate gel, resulting in Se loaded nanoparticles. These formulations were found to be more successful in cancer treatment.

RESUMO

Prostate cancer is one of the most life-threatening disorders that occur in males. It has now become the third most common disease all over the world, and emerging cases and spiking mortality rates are becoming more challenging day by day. Several approaches have been used to treat prostate cancer, including surgery, radiation therapy, chemotherapy, etc. These are painful and invasive ways of treatment. Primarily, chemotherapy has been associated with numerous drawbacks restricting its further application. The majority of prostate cancers have the potential to become castration-resistant. Prostate cancer cells exhibit resistance to chemotherapy, resistance to radiation, ADT (androgen-deprivation therapy) resistance, and immune stiffness as a result of activating tumor-promoting signaling pathways and developing resistance to various treatment modalities. Nanomedicines such as liposomes, nanoparticles, branched dendrimers, carbon nanotubes, and quantum dots are promising disease management techniques in this context. Nanomedicines can target the drugs to the target site and enhance the drug's action for a prolonged period. They may also increase the solubility and bioavailability of poorly soluble drugs. This review summarizes the current data on nanomedicines for the prevention and treatment of prostate cancer. Thus, nanomedicine is pioneering in disease management.

RESUMO

Inflammatory bowel disease (IBD) is a life-threatening complex disease. It causes chronic intestinal inflammation in GIT. IBD significantly affects people's lifestyles and carries a high risk of colon cancer. IBD involves the rectum, ileum, and colon, with clinical manifestations of bloody stools, weight loss, diarrhea, and abdominal pain. The prevalence of inflammatory disease is increasing dramatically worldwide. Over 16 million people are affected annually in India, with an economic burden of $6.8- $8.8 billion for treatment. Modern medicine can manage IBD as immunosuppressive agents, corticosteroids, tumor necrosis factor antagonists, integrin blockers, and amino-salicylates. However, these approaches are allied with limitations such as limited efficacy, drug resistance, undesired side effects, and overall cost, which cannot be ignored. Hence, the herbal bioactives derived from various plant resources can be employed in managing IBD. Science Direct, PubMed, Google, and Scopus databases have been searched for conclusively relevant herbal plant-based anti-inflammatory agent compositions. Studies were screened through analysis of previously published review articles. Eminent herbal bioactives, namely curcumin, resveratrol, ellagic acid, silybin, catechin, kaempferol, icariin, glycyrrhizin acid, berberine, quercetin, rutin, and thymol are reported to be effective against IBD. Herbal leads are promising treatment options for IBD; they have been shown to display antiinflammatory and antioxidant properties by targeting enzymes and regulating the expressions of various inflammatory mediators. Natural products have been reported to have anti-inflammatory properties in various clinical and preclinical studies, and some are available as herbal preparations. Herbal medicine would be promising in association with the implication of a novel drug delivery system for managing IBD.

RESUMO

Ulcerative colitis (UC) is a multifactorial disorder of the large intestine, especially the colon, and has become a challenge globally. Allopathic medicines are primarily available for the treatment and prevention of UC. However, their uses are limited due to several side effects. Hence, an alternative therapy is of utmost importance in this regard. Herbal medicines are considered safe and effective for managing human health problems. Chlorogenic acid (CGA), the herbal-derived bioactive, has been reported for pharmacological effects like antiinflammatory, immunomodulatory, antimicrobial, hepatoprotective, antioxidant, anticancer, etc. This review aims to understand the antiinflammatory and chemopreventive potential of CGA against UC. Apart from its excellent therapeutic potential, it has been associated with low absorption and poor oral bioavailability. In this context, colon-specific novel drug delivery systems (NDDS)are pioneering to overcome these problems. The pertinent literature was compiled from a thorough search on various databases such as ScienceDirect, PubMed, Google Scholar, etc., utilizing numerous keywords, including ulcerative colitis, herbal drugs, CGA, pharmacological activities, mechanism of actions, nanoformulations, clinical updates, and many others. Relevant publications accessed till now were chosen, whereas non-relevant papers, unpublished data, and non-original articles were excluded. The present review comprises recent studies on pharmacological activities and novel drug delivery systems of CGA for managing UC. In addition, the clinical trials of CGA against UC have been discussed.

RESUMO

In-situ gel technology is a promising drug delivery strategy that undergoes a 'sol to gel' transition upon administration, providing controlled and prolonged drug release. These gels are composed of cross-linked 3D networks of polymers, with hydrogels being a specific type of absorbing water while retaining their shape. Gelation can be triggered by various stimuli, such as temperature, pH, ions, and light. They offer several advantages like improved patient compliance, extended drug residence time, localized drug delivery, etc, but also have some disadvantages like drug degradation and limited mechanical strength. In-situ gel falls into three categories: temperature-sensitive, ion-sensitive, and pH-sensitive, but multi-responsive gels that respond to multiple stimuli have better drug release characteristics. The mechanism of in-situ gel formation involves physical and chemical mechanisms. There are various applications of in-situ gel, like ocular drug delivery, nose-to-brain delivery, etc. In this review, we have discussed the types, and mechanisms of in-situ gel & use of in-situ gel in the treatment of different diseases through various routes like buccal, vaginal, ocular, nasal, etc., along with its use in targeted drug delivery.

RESUMO

Malaria is still a major endemic disease transmitted in humans via Plasmodium-infected mosquitoes. The eradication of malarial parasites and the control measures have been rigorously and extensively deployed by local and international health organizations. Malaria's recurrence is a result of the failure to entirely eradicate it. The drawbacks related to malarial chemotherapy, non-specific targeting, multiple drug resistance, requirement of high doses, intolerable toxicity, indefinable complexity of Plasmodium's life cycle, and advent of drug-resistant strains of P. falciparum are the causes of the ineffective eradication measures. With the emergence of nanotechnology and its application in various industrial domains, the rising interest in the medical field, especially in epidemiology, has skyrocketed. The applications of nanosized carriers have sparked special attention, aiming towards minimizing the overall side effects caused due to drug therapy and avoiding bioavailability. The applications of concepts of nanobiotechnology to both vector control and patient therapy can also be one of the approaches. The current study focuses on the use of hybrid drugs as next-generation antimalarial drugs because they involve fewer drug adverse effects. The paper encompasses the numerous nanosized delivery-based systems that have been found to be effective among higher animal models, especially in treating malarial prophylaxis. This paper delivers a detailed review of diagnostic techniques, various nanotechnology approaches, the application of nanocarriers, and the underlying mechanisms for the management of malaria, thereby providing insights and the direction in which the current trends are imparted from the innovative and technological perspective.

RESUMO

Cancer is one of the deadliest illnesses of the 21st century. Chemotherapy and radiation therapies both have considerable side effects. Antitumor antibiotics are one of them. Coughs, common colds, fevers, laryngitis, and infectious disorders have all been treated with Andrographis paniculata for centuries. Extracts of Andrographis effectively treat various ailments, as well as cancer. The most active molecule in Andrographis paniculata is andrographolide a, diterpene, and lactone. Andrographis paniculata and its derivatives have long been used to treat various ailments. Anti-inflammatory and cancerfighting characteristics have been observed in Andrographolide. Andrographolide, a diterpene lactone separated from Andrographis paniculata, has also been shown to have important criticalessential biological protective properties. It has also been suggested that it could be used to treat major human diseases like-rheumatoid like rheumatoid, colitis, and Parkinsons disease. This summary aims to highlight Andrographolide as a promising cancer treatment option. Several databases were searched for andrographolides cytotoxic/anti-cancer effects in pre-clinical and clinical research to serve this purpose. Several studies have shown that Andrographolide is helpful in cancer medication, as detailed in this review.

RESUMO

Resveratrol (RSV) is a polyphenolic phytoalexin, and belongs to the stilbene family. RSV has several therapeutic activities such as cardioprotective, anticancer, and antioxidant. Apart from its therapeutic benefits, its pharmacological uses are limited due to low solubility, poor bioavailability, and short biological halflife. A researcher continuously focuses on overcoming the limitations of RSV through nanotechnology platforms to get the optimum health benefits. In this context, nanocarriers are pioneering to overcome these drawbacks. Nanocarriers possess high drug loading capacity, thermal stability, low production cost, longer shelflife, etc. Fortunately, scientists were proficient in delivering resveratrol-based nanocarriers in the present scenario. Nanocarriers can deliver drugs to the target sites without compromising the bioavailability. Thus, this review highlights how the latest nanocarrier systems overcome the shortcomings of RSV, which will be good for improving therapeutic efficacy and bioavailability. Moreover, recent updates on resveratrol-based novel formulations and their clinical trials have been addressed to manage several health-related problems.

RESUMO

The World Health Organization identifies tuberculosis (TB), caused by Mycobacterium tuberculosis, as a leading infectious killer. Although conventional treatments for TB exist, they come with challenges such as a heavy pill regimen, prolonged treatment duration, and a strict schedule, leading to multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains. The rise of MDR strains endangers future TB control. Despite these concerns, the hunt for an efficient treatment continues. One breakthrough has been the use of nanotechnology in medicines, presenting a novel approach for TB treatment. Nanocarriers, such as lipid nanoparticles, nanosuspensions, liposomes, and polymeric micelles, facilitate targeted delivery of anti-TB drugs. The benefits of nanocarriers include reduced drug doses, fewer side effects, improved drug solubility, better bioavailability, and improved patient compliance, speeding up recovery. Additionally, nanocarriers can be made even more targeted by linking them with ligands such as mannose or hyaluronic acid. This review explores these innovative TB treatments, including studies on nanocarriers containing anti-TB drugs and related patents.

RESUMO

Allergies are a major health issue. Allergen avoidance, antihistamines, and corticosteroids do not treat the pathology's causes, therefore long-term therapy is essential. Long-term allergen-specific immunotherapy builds immune tolerance to the allergen. Unfortunately, immunotherapies for all allergens are not available, and adverse reactions during therapy, especially in severely allergic persons, remain a worry. In this regard, cell and bio- or nanomaterial-based allergy treatments are promising. This overview covers the most important tactics from these two strategies with examples. Nanotechnology encompasses science, engineering, and technology at 1-100 nm. Due to their one-of-a-kind characteristics, nanomaterials can be used in healthcare. Small molecules' chemical and physical properties are modified by the system's size, shape, content, and function. Toxicity and hypersensitivity reactions need to be evaluated. Regulating the physico-chemical properties of numerous accessible structures would make clinical diagnosis and therapy safer and more successful. Dendrimeric antigens, nanoallergens, and nanoparticles can mimic carrier proteins, boost specific IgE binding, and improve signal detection in allergy diagnosis. In immunotherapy, several allergenic structures like glycodendrimers, liposomes, polymers, and nanoparticles have been used as adjuvants, protectors, or depots for allergens. Nanotechnology has the potential to substantially improve both the diagnosis and treatment of allergies.

RESUMO

Oral and injectable drug administration have recently been replaced with transdermal drug delivery (TDD) approaches, which are less intrusive, less likely to be rejected by patients, and easier to administer. There is still room for improvement in the treatment of gout with the use of a TDD system. Gout has become a worldwide epidemic and a severe threat to human beings. Gout treatment can be accomplished in various ways, including orally and intravenously. Several traditional options are still useless, cumbersome, and potentially dangerous. Hence, gout therapeutic options are desperately required for more effective and less toxic drug delivery methods. Anti-gout medications using TDD could substantially influence obese people in the future, even if most trials are still in the animal stages. Thus, this review aimed to provide a concise overview of recent TDD technologies and anti-gout medication delivery methods that improved therapeutic efficacy and bioavailability. Moreover, clinical updates on investigational drugs have been discussed to address the potential findings against gout.

RESUMO

Curcumin is a potent bioactive compound of Curcuma longa. Curcumin comprises a broad spectrum of biological activities, including hepatoprotective, anticancer, antimicrobial, anti-inflammatory, antitumor, anti-oxidant, etc. However, its low aqueous solubility, rapid excretion, and poor bioavailability restricted its therapeutic uses. To resolve these issues, novel nano-systems have now been developed to increase the bioactivity and bioavailability of curcumin by lowering the particle size, altering the surface, and increasing the efficacy of its encapsulation with various nanocarriers. Nanotechnology-based treatments can broaden the outlook for individuals with critical conditions. This article explores curcumin-based nanoparticulate carrier systems that should be employed to overcome this natural ingredient's inherent limitations. These nanocarriers also provide physical and chemical stability by encapsulating the drug into the core or matrix of the lipids or polymers. Nanotechnologists developed curcumin-encapsulated various nanoparticulate systems, including solid lipidic nanoparticles, polymeric nanoparticles, nano-structured lipid carriers, polymer conjugates, etc., to improve curcumin bioavailability and boost the sustained release of curcumin to target cells.

RESUMO

Malaria is a life-threatening parasitic disease that affects millions of people worldwide, especially in developing countries. Despite advances in conventional therapies, drug resistance in malaria parasites has become a significant concern. Hence, there is a need for a new therapeutic approach. To combat the disease effectively means eliminating vectors and discovering potent treatments. The nanotechnology research efforts in nanomedicine show promise by exploring the potential use of nanomaterials that can surmount these limitations occurring with antimalarial drugs, which include multidrug resistance or lack of specificity when targeting parasites directly. Utilizing nanomaterials would possess unique advantages over conventional chemotherapy systems by increasing the efficacy levels while reducing side effects significantly by delivering medications precisely within the diseased area. It also provides cheap yet safe measures against Malaria infections worldwide-ultimately improving treatment efficiency holistically without reinventing new methods therapeutically. This review is an effort to provide an overview of the various stages of malaria parasites, pathogenesis, and conventional therapies, as well as the treatment gap existing with available formulations. It explores different types of nanocarriers, such as liposomes, ethosomal cataplasm, solid lipid nanoparticles, nanostructured lipid carriers, polymeric nanocarriers, and metallic nanoparticles, which are frequently employed to boost the efficiency of antimalarial drugs to overcome the challenges and develop effective and safe therapies. The study also highlights the improved pharmacokinetics, enhanced drug bioavailability, and reduced toxicity associated with nanocarriers, making them a promising therapeutic approach for treating malaria.
