Go to Editorial ManagerObjective Examine how transdermal drug delivery systems can yield advantages over conventional methods, especially in terms of maximizing efficacy while reducing toxicity and bypassing hepatic metabolism. The study also aims to review ethosomal systems as a novel nanocarrier for enhanced transdermal drug delivery. Methods A comprehensive review of transdermal drug delivery systems with an accent on ethosomes. Three types of ethosomal systems were studied based on their composition, which are transethosomes, binary ethosomes, and classical ethosomes. These methods were explored to determine how the differences in preparation techniques and formulation methods influenced system properties, including vesicle size, zeta potential, drug entrapment efficiency, skin penetration, and stability. Results Ethosomes are emerging as potent transdermal drug carriers.They can encompass drugs with a broad diversity of physicochemical properties, and due to their high ethanol levels, ethanol has been used to increase the penetration of the drug molecules by disrupting the lipid structure of the stratum corneum.(Due to the deeper skin layers,it may include the subcutaneous layer,but the target for transdermal drug delivery is that the drug is systemically absorbed before reaching this layer). Transethosomes and binary ethosomes exhibited better flexibility and permeation than conventional ethosomes Conclusions Ethosomal systems have better drug penetration, lower toxicity, and higher therapeutic efficacy.This makes them a promising new way to give drugs through the skin. The performance of formulation ingredients and preparation methods has a big effect on how well they work. More research and improvements to these systems could make them more useful in medicine and pharmacology.
One of the most interesting pharmaceutical drug delivery systems with minimally invasive technique are Microneedles. In the recent years, many researchers have concluded that Microneedles can be a leading method in the future. As a drug delivery system, Microneedles can improve drug delivery by avoiding many barriers that were linked with the conventional system, these unique properties could make Microneedles widely used. The primary mechanism for improving drug delivery to the targeted site with minimal complications is by creating micro-sized pores in the skin layer. The growing interest of Microneedles in biomedical and pharmaceutical research is obtained by easy delivery of active ingredient with low invasive technique. Vaccines, peptides, and hormones are examples of molecules delivered by Microneedles. In this review, we will discuss Microneedles efficiency as drug delivery carriers, fabrication materials, and several related patents
Floating Drug Delivery Systems (FDDS) is a very recent approach in the development of oral drug delivery systems, which can be employed to control the gastric emptying time of filled device for both sustained and controlled release (CR) preparations, to locate the CR in a particular site, to minimize the drug loss and to improve drug delivery. These types of systems have a low density, are buoyant in gastric fluid, maintain longer residence time in the stomach with controlled drug release. FDDS can be prepared in tablets, capsules, powders, granules, films and microspheres and are especially valuable when dealing with highly water-soluble drugs with short halflife, having absorption window low in the gut or having instability at intestinal pH. There are several types of FDDS such as effervescent, non-effervescent, raft-forming, the hydrodynamically balanced and the inflatable system that uses different ways to float and consequent modification of release. Their performance is highly dependent upon physiological parameters, such as gastric pH, motility, meal content, age, and body position. FDDS have various advantages such as increased bioavailability, rapid onset of action, a lower frequency of dose administration, better patient compliance, and long site-specific action in the stomach, which is useful in the case of gastroesophageal reflux disease (GERD) and peptic ulcers. Nevertheless, gastric emptying variability and complexity of the formulation still pose obstacles. Newer excipients and polymers and newer carriers will continue to improve these systems, making FDDS a potential weapon for future gastroprotective and controlled-release therapies.
dandruff chronic and recurring scalp condition that characterised by excessive flaking, itching. Overactive sebaceous glands, microbial imbalance, impaired skin barrier function, and susceptibility to infection are among the overlapping causative factors that distinguish it from seborrheic dermatitis. Malassezia fungi, particularly Malassezia pityriasis, play a crucial role in the pathogenesis of dandruff by metabolizing lipids, releasing inflammatory mediators, and disrupting the stratum corneum barrier. Antifungal, exfoliating, and anti-inflammatory ingredients such as ketoconazole, zinc pyrithione, selenium sulfide, and salicylic acid are frequently found in conventional anti-dandruff shampoos. However, these formulations are limited by their low bioavailability, short duration on the scalp, poor penetration into the hair follicles, and the potential for irritation with prolonged use. Recent advances in nanotechnology have enabled the development of novel drug delivery systems, such as liposomes, solid lipid nanoparticles, lipid nanocarriers, polymer nanoparticles, microemulsifiers, and advanced exosome-based systems, significantly improving the effectiveness of anti-dandruff shampoos. In addition to reducing discomfort and the frequency of application, these nanocarriers enhance drug deposition in the scalp, target hair follicles, ensure controlled release, and stabilize active ingredients. Furthermore, herbal enhancers, including coconut oil, aloe vera, green tea and rosemary, possess synergistic antifungal, anti-inflammatory, antioxidant, and scalp barrier-repairing properties when added. Thus, by simultaneously addressing microbial overgrowth, inflammation, and scalp barrier damage, multifunctional, nanotechnology-enhanced shampoos offer an effective approach to tackling the multifactorial nature of dandruff. This review underscores the potential of nanoparticle-based anti-dandruff shampoos to increase therapeutic efficacy by highlighting recent developments, formulation considerations and evaluation techniques, related to these products.
ABSTRACT Psoriasis (PSO) is an immune-mediated dermatological disorder marked by thick, erythematous, scaly plaques resulting from rapid, excessive cellular growth. Anti-inflammatory agents, immunosuppressant’s, and additional pharmaceuticals serve as the principal therapeutic strategy for psoriasis to alleviate symptoms, diminish inflammation, and inhibit the proliferation and division of epidermal cells. Nevertheless, these drugs generally include disadvantages that impose significant physiological and pathological burdens on patients, including inadequate targeting, brief half-lives, limited absorption rates, and severe toxic side effects. Researchers have recently concentrated significant effort on employing delivery systems for the topical administration of drugs to affected psoriatic skin regions. These systems increase pharmacological efficacy, stability, and penetration. More therapeutic concepts for the treatment of PSO are made possible by the ongoing development of numerous multifunctional topical delivery technologies. This publication reviews various delivery strategies, including hydrogels, nanoparticles, microneedles, micelles, dendrimers, liposomes, nanoemulsions, and vesicles, for topical therapy of PSO and delineates their current developmental status in clinical treatment. It is expected to facilitate the progression of PSO treatment methodologies and provide a benchmark for the development of novel topical delivery systems.
Diabetic ulcer is a significant medical issue affecting millions of patients globally due to consequential morbidity, mortality, and health care system costs. The complex pathophysiological process of delayed wound healing in diabetic patients remains inadequately addressed with conventional treatment modalities. This review summarises recent advances in smart, responsive engineered drug delivery systems for the treatment of diabetic ulcers. Moreover, we exemplify these strategies using emerging technologies, including nanotechnology, hydrogel matrices, stimulus-responsive systems, and bioactives. New methodologies, including next-generation approaches such as 3D-printed scaffolds, nanofiber systems, and theranostic platforms, are presented as alternative treatment options that could change the landscape of diabetes-related wound care. Discussions on the challenges of translation, regulation, and application of new pharma-technologies in clinical research are offered
With the increasing applications of gold nanoparticles in cancer treatment and medical delivery, it has become necessary to study the biological effects of gold nanoparticles. The study aimed to evaluate the biological effects of gold nanoparticles against the mcf-7 & mda-mb-231 cell line. Gold nanoparticles were characterized using several analytical techniques including X-ray Diffraction (XRD), Ultraviolet-Visible Spectroscopy (UV-VIS), Energy Dispersion X-ray (EDX), Atomic Force Microscopy (AFM), and Filed Emission Scanning Electron Microscopy (FE-SEM).. The characterization results confirmed the successful synthesis of high purity quasi-spherical gold nanoparticles with particle sizes ranging from 38 to 59 nm. The cytotoxic effect of the synthesized AuNPs was investigated using the MTT assay on both MCF-7 and MDA-MB-231 cell lines at six different concentrations. The results indicated a concentration-dependent inhibitory effect of gold nanoparticles on both cancer cell lines, with a high cytotoxic activity observed against the MDA-MB-231 cell line. The results of this study indicate the potential use of gold nanoparticles against various types of cancer cell lines, as well as the potential use of gold nanoparticles in treating cancerous diseases with vivo cell.
Objective Angiogenesis is an essential process in tumor growth and progression, and thus it represents a promising therapeutic target. Lawsonia inermis (henna) is a widely-used traditional medicine with different biological applications, and its bioactive components, especially lawsone, showed anticancer activity. The objective of this research was to measure the anti-angiogenic and antioxidant properties of Lawsonia inermis leaf ethanolic extract in ex vivo and in vivo systems. Methods Soxhlet was used to prepare the ethanolic extract of the Lawsonia inermis leaf. The ex vivo rat aorta ring assay was used to test the anti-angiogenic activity at the concentrations of 100, 50, 25, 12.5, and 6.25 µg/mL. The in vivo chick chorioallantoic membrane (CAM) assay was employed to confirm the anti-angiogenic effect at a concentration of 10 mg/mL. DPPH radical scavenging assay was used to determine the antioxidant activity with a concentration range of 3.125 to 100 µg/mL. Results The ethanolic extract demonstrated high anti-angiogenic activity in the rat aorta ring with 65.82% inhibition at 100 µg/mL and dose-dependent inhibition with an IC 50 of 54.2 µg/mL. In the CAM assay, acetylsalicylic acid (positive control) resulted in complete suppression of vascularization, validating the assay system. The extract exhibited a concentration-dependent radical scavenging ability of DPPH radical with an IC 50 value of 0.05 µg/mL. Conclusions Lawsonia inermis ethanolic extract has strong anti-angiogenic and antioxidant properties, which implies its possible application as a treatment of angiogenesis-related disorders, such as cancer. The anti-angiogenic effect was confirmed in both ex vivo and in vivo models.
Objective To develop and disseminate a novel multimodal therapeutic concept for movement disorders (MD) that will not only aim at symptom suppression, but on the functional reorganization of motor networks allowing more stable and meaningful recovery. Methods A net-based model was employed by creating three integrated modules: • Pharmacological tuning in network physiology. • There are some interventional and non-invasive co-modulations of the invasive ones. • Task specific motor retraining at therapeutically optimum doses, in order to reconstruct maladaptive circuits. It was constructed through observations in systems neuroscience and functional imaging of network dynamics involving the basal ganglia, cortex, thalamus, and cerebellum. Results The intervention aims beyond alleviation of symptoms to normalize abnormal connectivity, oscillatory activity and maladaptive plasticity in the respective motor networks. While clinical validation is empirical, theoretical analysis supports the idea that combination of pharmacological, neuromodulator and motor retraining approach might promote functional reorganization and would be effective in longer term improvement. Conclusions Such a multimodal, network-informed therapy could outperform current MD approaches by not only relieving symptoms, but also facilitating adaptive motor network reorganization. This combination of therapies is expected to result in such a superior long-term functional outcome and less variability in patient response.
