Dermal Delivery of Hypericum perforatum (L.)Loaded Nanogel: Formulation to Preclinical Psoriasis Assessment.

BACKGROUND: Nanophytosomes represent an effective choice for topical drug delivery systems thanks to their small size, general non-toxicity, ease of functionalization and high surface to volume ratio. The goal of the current study was to investigate the potential benefits of using Hypericum perforatum extract nanogel as a means of improving skin penetration and prolonging skin deposition in dermatitis similar to psoriasis. METHOD: Nanophytosomes (NPs) were developed, optimised and thoroughly characterised. The optimised NPs were then placed in a Carbopol gel base matrix and tested ex-vivo (skin penetration and dermatokinetic) and in-vivo (antipsoriatic activity in an Imiquimod-induced psoriatic rat model). RESULTS: The optimised NPs had a spherical form and entrapment efficiency of 69.68% with a nanosized and zeta potential of 168nm and -10.37mV, respectively. XRD spectra and transmission electron microscopy tests confirmed the plant botanical encapsulation in the NPs. Following 60 days of storage at 40 ± 2°C/75 ± 5% RH, the optimised formula remained relatively stable. As compared to extract gel, nano-gel showed a much-improved ex vivo permeability profile and considerable drug deposition in the viable epidermal-dermal layers. When developed nano-gel was applied topically to a rat model of psoriasis, it demonstrated distinct in vivo anti-psoriatic efficacy in terms of drug activity and reduction of epidermal thickness in comparison to other formulations and the control. ELISA and histopathologic studies also demonstrated that nano-organogel had improved skin integrity and downregulated inflammatory markers (IL-17, IL-6, IFN-γ and MCP-1). CONCLUSION: Findings suggest that a developed plant botanicals-based nanogel has a potential for the treatment of psoriasis-like dermatitis with better skin retention and effectiveness.

Process Optimization of Tinospora cordifolia Extract-Loaded Water in Oil Nanoemulsion Developed by Ultrasound-Assisted Homogenization.

Nanoemulsions are gaining interest in a variety of products as a means of integrating easily degradable bioactive compounds, preserving them from oxidation, and increasing their bioavailability. However, preparing stable emulsion compositions with the desired characteristics is a difficult task. The aim of this study was to encapsulate the Tinospora cordifolia aqueous extract (TCAE) into a water in oil (W/O) nanoemulsion and identify its critical process and formulation variables, like oil (27-29.4 mL), the surfactant concentration (0.6-3 mL), and sonication amplitude (40% to 100%), using response surface methodology (RSM). The responses of this formulation were studied with an analysis of the particle size (PS), free fatty acids (FFAs), and encapsulation efficiency (EE). In between, we have studied a fishbone diagram that was used to measure risk and preliminary research. The optimized condition for the formation of a stable nanoemulsion using quality by design was surfactant (2.43 mL), oil concentration (27.61 mL), and sonication amplitude (88.6%), providing a PS of 171.62 nm, FFA content of 0.86 meq/kg oil and viscosity of 0.597 Pa.s for the blank sample compared to the enriched TCAE nanoemulsion with a PS of 243.60 nm, FFA content of 0.27 meq/kg oil and viscosity of 0.22 Pa.s. The EE increases with increasing concentrations of TCAE, from 56.88% to 85.45%. The RSM response demonstrated that both composition variables had a considerable impact on the properties of the W/O nanoemulsion. Furthermore, after the storage time, the enriched TCAE nanoemulsion showed better stability over the blank nanoemulsion, specially the FFAs, and the blank increased from 0.142 to 1.22 meq/kg oil, while TCAE showed 0.266 to 0.82 meq/kg.

A comprehensive quality control and cost comparison study of branded and generic angiotensin receptor blockers.

This study was designed to assess both the quality and cost aspects of various branded and generic formulations of angiotensin receptor blockers, specifically Irbesartan, Losartan Potassium, Olmesartan Medoxomil, Telmisartan, and Valsartan. The collected samples underwent distinct quality evaluations using the methods outlined in different global Pharmacopoeias (British Pharmacopoeia/European Pharmacopoeia, Indian Pharmacopoeia and United States Pharmacopoeia). These drugs were characterized using Fourier-Transform Infrared Spectroscopy and Nuclear Magnetic Resonance techniques, while their quality and concentration were analysed using High Performance Liquid Chromatography. The release profile of the drugs was examined through dissolution testing. Additionally, a cost comparison analysis was carried out by determining the prevailing market prices of the drugs. The evaluated branded and generic angiotensin receptor blockers were found to meet the established standards for impurities, active drug content, and dissolution as set by these Pharmacopoeias, indicating their optimal quality. Notably, the generic drugs exhibited significantly lower costs compared to their branded counterparts. This study confirms that the quality of generic angiotensin receptor blockers is equivalent to that of their branded counterparts. Consequently, these findings support the practicality of utilizing generic drugs as a more economically sustainable and cost-effective approach to managing diseases, especially those of chronic nature.

Healing Potential of Propolis Extract-Passiflora edulis Seed Oil Emulgel Against Excisional Wound: Biochemical, Histopathological, and Cytokines Level Evidence.

Propolis is rich in natural bioactive compounds, and considering its importance for many skin therapies, emulgel was prepared. This study examines how a propolis extract (PE) and Passiflora edulis seed (PS) oil emulgel affect rat deep skin wound healing. Based on preset criteria of maximum drug content and optimum drug permeation through the stratum corneum along with drug retention in the skin layers, an optimized emulgel formula based on Box-Behnken factorial design was prepared and used for subsequent in vitro and in vivo evaluations. In vivo wound-healing activities of emulgel and control treatments were investigated in a rat model. The optimized emulgel formula exhibited superior healing activity compared with plain PE suspension-treated rats on day 14 of wounding. Histopathological investigations of hematoxylin and eosin and Masson's Trichrome-stained skin sections supported this effect. Emulgel promotes cutaneous wound healing through a variety of mechanisms, including anti-inflammatory through modulation of cytokines tumor necrosis factor-α, interleukin (IL)-1ß, and IL-6 production, and promotion of collagen fiber formation, all of which contribute to tissue remodeling. Furthermore, when compared with propolis suspension, emulgel showed significant antioxidant and anti-inflammatory effects. Emulgel significantly increased the skin's hydroxyproline level, antioxidant potential, wound contraction, increased penetration, and localized propolis deposition across the skin. Incorporation of PS oil into the emulgel accelerates the tissue regeneration process. The findings suggest that 5% propolis emulgel could be used as an alternative to treat wounds.

Size-Dependent Antibacterial, Antidiabetic, and Toxicity of Silver Nanoparticles Synthesized Using Solvent Extraction of Rosa indica L. Petals.

In this study, silver nanoparticles (AgNPs) are synthesized through a green approach by employing Rosa indica L. petal (RE) extracts as reducing and stabilizing agents, which are extracted using three different solvents: ethanol (Et), acetone (Ac), and water (Aq). The phase formation of the AgNPs is confirmed using X-ray diffraction (XRD). Morphological analysis is performed using a field-emission scanning electron microscope (FESEM), which reveals that the AgNPs are spherical in shape. The size is estimated using ImageJ software, which is found to be ~12, 18, and 770 nm for RE-Ac-Ag, RE-Et-Ag, and RE-Aq-Ag, respectively. The phytochemicals of Rosa indica L. petals involved in the formation of the AgNPs are studied using Fourier transform infrared spectroscopy (FTIR). Finally, these materials are studied for their antibacterial, antidiabetic, antioxidant, and hemolytic activity, as well as cell toxicity properties. The materials, RE-Ac-Ag and RE-Et-Ag, are found to be more effective than RE-Aq-Ag in inhibiting E. coli (Gram-negative bacteria) and S. aureus (Gram-positive bacteria). Hemolytic studies reveal that all of the samples show concentration-dependent activity up to 50 µg/mL. RE-Ac-Ag and RE-Et-Ag exhibit nonhemolytic behavior, whereas RE-Aq-Ag remains nonhemolytic until 100 µg/mL. The antidiabetic ability of the AgNPs is evaluated using α-amylase inhibition assay (DNSA assay) and α-glucosidase inhibition assay. The results are found to be effective, with IC50 values of α-amylase and α-glycosidase being 50, 50, and 75 µg/mL for RE-Et-Ag, RE-Ac-Ag, and RE-Aq-Ag, respectively. DPPH assay shows that the AgNPs inhibited the antioxidants well, with IC50 values of 40 µg/mL for RE-Et-Ag and RE-Ac-Ag and 60 µg/mL for RE-Aq-Ag. The toxicity study reveals that the AgNPs show size- and concentration-dependent behavior. Overall, it is realized from the findings that RE-Ac-Ag, RE-Et-Ag, and RE-Aq-Ag show size-dependent antibacterial, antidiabetic, and toxicity properties.

Multidrug Resistance in Cancer Cells: Focus on a Possible Strategy Plan to Address Colon Carcinoma Cells.

Even though various treatment methods are available for cancer, the death curve is not reducing. The diagnosis of cancer at the fourth stage and drug resistance are the leading reasons for treatment failure and lower survival rates. In this review article, we summarize the possible pitfalls during cancer treatment in general, which mainly include multidrug resistance, and propose a hypothesis for colorectal cancer specifically. We also evaluate multidrug resistance in cancer in general and colorectal cancer in particular and hypothesize a concept based on combination therapy with 5-fluorouracil, curcumin, and lipids for the possible management of colorectal cancer. In addition, a hypothetical approach, combining a synthetic agent and a natural chemotherapeutic agent, to treating colorectal cancer is also discussed. This hypothesis could improve the management of colorectal cancer.

Multidrug Resistance of Cancer Cells and the Vital Role of P-Glycoprotein.

P-glycoprotein (P-gp) is a major factor in the multidrug resistance phenotype in cancer cells. P-gp is a protein that regulates the ATP-dependent efflux of a wide range of anticancer medicines and confers resistance. Due to its wide specificity, several attempts have been made to block the action of P-gp to restore the efficacy of anticancer drugs. The major goal has been to create molecules that either compete with anticancer medicines for transport or function as a direct P-gp inhibitor. Despite significant in vitro success, there are presently no drugs available in the clinic that can "block" P-gp-mediated resistance. Toxicity, unfavourable pharmacological interactions, and a variety of pharmacokinetic difficulties might all be the reason for the failure. On the other hand, P-gp has a significant effect in the body. It protects the vital organs from the entry of foreign bodies and other toxic chemicals. Hence, the inhibitors of P-gp should not hinder its action in the normal cells. To develop an effective inhibitor of P-gp, thorough background knowledge is needed in this field. The main aim of this review article was to set forth the merits and demerits of the action of P-gp on cancer cells as well as on normal cells. The influence of P-gp on cancer drug delivery and the contribution of P-gp to activating drug resistance were also mentioned.

Nanotechnology-based Medicinal Products and Patents: A Promising Way to Treat Psoriasis

Psoriasis is an autoimmune skin disorder that is characterised by chronic inflammation and erythematous scaly patches. It has a significant impact on the patient's quality of life and can cause psychological stress. There are several aspects that cause psoriasis, for instance, environmental issues, immune disorders, bacterial infections, and genetic issues. Plentiful therapeutic means or treatments are accessible, but not any of them can completely and effectively cure psoriasis without hindering patient compliance. Hence, it becomes challenging to discover a new drug moiety or any drug delivery method to cure psoriasis. Conventional treatment of psoriasis involves anti-inflammatory agents, immune suppressants, phototherapy, and biological treatment, which were given in different forms such as topical, oral, or systemic formulations, but these all were unsuccessful to accomplish complete reduction of psoriasis as well as causing adverse side effects. In terms of dose frequency, doses, efficacy, and side effects, nanotechnology-based new formulations are the most promising prospects for addressing the challenges and limits associated with present psoriasis formulations. Hence, our major goal of this review is to present various advanced nanotechnological approaches for the effective topical treatment of psoriasis. In short, nano-formulations continue to be formed as very promising modalities in the treatment of psoriasis as they suggest improved penetration, targeted delivery, increased safety, and efficacy.
