Hydration behavior of D-calcium pantothenate (vitamin B5) in the presence of sugar-based deep eutectic solvents at different temperatures: experimental and theoretical study

Considerable efforts have been devoted in recent years to enhancing the efficacy medicinal substance, leading to the discovery of innovative drug formulations and delivery techniques. The successful design of these processes necessitates a profound understanding at the molecular level of how these substances interact with biological membranes. Thorough thermodynamic investigations provide invaluable insights into these interactions and aid in selecting suitable compounds for pharmaceutical production. This study aims to determine the density and speed of sound for D-calcium pantothenate in mixtures of water and deep eutectic solvents (DESs), specifically choline chloride/sucrose, choline chloride/ glucose, and choline chloride/ fructose (with 2:1 molar ratio) over a temperature range of 288.15 K to 318.15 K under atmospheric pressure. In order to predict the behavior of molecules, COSMO model (the Conductor-Like Screening Model) offer complementary strengths in quantum chemistry. This approach allows for calculating solvation free energies, making it ideal for predicting properties like solubility, where understanding solvent-solute interactions is crucial. By correlating the measured parameters using standard relationships, important partial molar parameters such as apparent molar volumes and apparent molar isentropic compressibility are calculated. Additionally, apparent molar isobaric expansion, and Hepler’s constant are derived from the density and speed of sound data. The experimental apparent molar volumes, and apparent molar isentropic compressibility data is fitted to the Redlich-Meyer equation to obtain significant quantities such as standard partial molar volume, and partial molar isentropic compression. The comprehensive thermodynamic analysis of this studied system holds immense significance for advancements in the pharmaceutical industry.

In vitro Characterization and Drug Release Studies of Ethambutol-Loaded Nanoparticles for Pulmonary Delivery

Background: The development of more effective drug delivery techniques is necessary to increase treatment efficacy and patient compliance since tuberculosis (TB) is still a serious worldwide health concern. Ethambutol is a vital aspect of TB treatment, and using nanoparticles to carry it to the lungs may provide targeted delivery and prolonged release, which might enhance the effectiveness of the treatment. Objective: This work aimed to optimize the formulation for prolonged drug release by synthesizing and assessing ethambutol-loaded nanoparticles using the desolation technique with albumin as the polymer. Additionally, the effects of different drug-polymer ratios and stirring rates were investigated. Methods: Nine formulations of ethambutol-loaded nanoparticles were prepared by varying the drug-polymer ratios (1:1 to 1:2) and stirring speeds (500 to 1500 rpm). Key parameters, such as particle size, drug entrapment efficiency, and zeta potential, were measured. The optimized formulation was selected based on the smallest particle size and highest drug entrapment efficiency. Scanning electron microscopy was used to analyze the surface morphology of the nanoparticles. The in vitro drug release profile of the optimized formulation was studied over 24 hours. Results: Increasing the drug-polymer ratio from 1:1 to 1:2 increased nanoparticle size from 192.1 nm to 605.06 nm and decreased drug entrapment efficiency from 75.7%±0.08 to 34%±0.06. Higher stirring speeds (500 to 1500 rpm) also led to larger particle sizes and reduced drug entrapment due to polymer self-aggregation. Zeta potential values ranged from -5.56 to -25.6 mV. Scanning electron microscopy confirmed smooth, spherical nanoparticles. The optimized formulation, EN-5, exhibited the smallest particle size and highest drug entrapment efficiency. In vitro drug release studies showed a sustained ethambutol release, with 42.66±1.53% released in 12 hours and 79.082±2.98% in 24 hours. Conclusion: Ethambutol-loaded nanoparticles having the ability to transport drugs to the lungs over an extended period of time were developed and optimized in the study. With improved drug delivery systems, the optimized formulation showed notable drug entrapment efficiency and controlled release, suggesting its potential to improve tuberculosis therapy.

The Mechanism and Latest Research Progress of Blood-Brain Barrier Breakthrough.

The bloodstream and the central nervous system (CNS) are separated by the blood-brain barrier (BBB), an intricate network of blood vessels. Its main role is to regulate the environment within the brain.

Intranasal administration of liposomes: Potential brain delivery with prospective ophthalmic reach

The low efficacy of drug transportation from the bloodstream to specific tissues remains a challenge in drug delivery to the central nervous system (CNS), primarily because of the presence of the blood-brain and blood-retinal barriers. There is a need for non-invasive drug delivery techniques to the CNS given the intrusive nature of and potential patient burden associated with intraventricular, intrathecal, and intravitreal administration. Recently, the focus has shifted towards intranasal (i.e., nose-to-brain) drug delivery. Furthermore, there have been reports indicating that the use of drug nanocarriers, such as liposomes, facilitates efficient drug delivery via the intranasal pathway. This study investigates the brain penetration capabilities of intranasally administered liposomes using the hydrophobic fluorescent molecule, 1,1′-dioctadecyl-3,3,3′,3′-tetramethyl lindodicarbocyanine, 4-chlorobenzene sulfonate salt (DiD), as a model compound. The primary objective of this study was to elucidate the penetration of intranasally administered liposomes into the CNS, including the eyes. An examination of DiD distribution in the dissected brain and ocular tissues showed that DiD concentrations were elevated specifically at the limbus of the ocular tissue when surface-modified liposomes were employed. These findings suggest that intranasal liposome administration can deliver drugs to the posterior ophthalmic region, specifically the optic nerve, in addition to the brain.

Jet injection through microneedles for large volume subcutaneous delivery

Subcutaneous (SC) drug delivery offers several advantages over intravenous (IV) delivery including: self-administration, improved patient experience, and reduced treatment costs. Unfortunately, each SC delivery is currently limited to ∼ 2.25 mL with IV administration required when the delivery volume exceeds this value. In this work, we explore a new technique for large volume subcutaneous drug delivery that uses microneedles to break through the epidermis then forms the liquid drug into many small jets that penetrate past the ends of the microneedles and into the subcutaneous (or muscle) tissue. By performing multiple simultaneous injections, this delivery approach avoids the volume limitations of SC delivery, and thus may be able to greatly increase the volume we can deliver to this space. Here, we present a novel multi-jet prototype that forms seven simultaneous jets through 30G needles that have been shortened to have an exposed length of just ∼ 1mm. The jet speed, shape, and volume of jets formed through these microneedles are measured to assess the consistency of jet production through the microneedles. We then perform jet injections of volumes up to 3.9 mL into ex vivo porcine tissue. The results demonstrate the successful delivery (>95 %) of 3.9 mL in just 0.3 s using jet injection performed through microneedles. This volume is almost double the maximum volume of current autoinjectors and the perceived limit for subcutaneous injection (2.25 mL). We also find that jet speeds of 70 m/s and below do not achieve complete delivery of 3.9 mL with our prototype system, and that the addition of microneedles leads to more consistent large volume delivery than equivalent needle-free injections. These results demonstrate the promise of multi-jet injection through microneedles to accommodate volumes much greater than current autoinjectors, and thus potentially allow patient self-administration in many more delivery applications.

A system for high-speed NIR transmission imaging of drug delivery in tissue

The development and characterisation of new drug delivery techniques often requires visualising the location of delivered fluid in tissue samples. The opacity of tissue means that this can typically only be done with destructive post-processing techniques, or with the use of ionising radiation (eg. X-ray). In this work we present a novel approach to imaging fluid during delivery into port-mortem tissue samples using transmission imaging at near-infrared (NIR) wavelengths. The system makes use of wavelengths just above the visible range (765 nm), at which tissue is relatively transparent, and to which visible light cameras remain sensitive. Thus, this system utilised a low-cost high-speed (1000 fps) camera and optical components designed for use with visible light. We demonstrate that this NIR imaging system is capable of measuring the location of delivered fluid and an 18G needle in 12 mm thick samples of muscle and fat tissue at 1000 fps. Predictions of needle depth using the imaging system compared well to the known needle position in the tissue: the standard deviation of the depth measurements was approximately 0.7 mm in muscle and 1.2 mm in fat. NIR images captured during and after delivery compare favourably with observations made using 2D X-ray and by sectioning the tissue post-injection. This system can support studies of fluid dispersion and penetration into tissue by new drug delivery systems, thus assist the development of new drug delivery techniques.

Poly(2-oxazoline)-Based Thermoresponsive Stomatocytes.

The design of biocompatible and biodegradable nanostructures with controlled morphological features remains a predominant challenge in medical research. Stimuli-responsive vesicles offer significant advantages in drug delivery, biomedical applications, and diagnostic techniques. The combination of poly(2-oxazoline)s with biodegradable polymers could provide exceptional biocompatibility properties and be proposed as a versatile platform for the development of new medicines. Therefore, poly(2-ethyl-2-oxazoline) (PEtOx) and poly(2-isopropyl-2-oxazoline) (PiPrOx) possessing a hydroxy terminal group that acts as an initiator for the ring-opening polymerization of d,l-lactide (DLLA) have been utilized in this study. The resulting amphiphilic block polymers were used to create polymersomes, which undergo solvent-dependent reorganization into bowl-shaped vesicles or stomatocytes. By blending PEtOx-b-PDLLA and PiPrOx-b-PDLLA copolymers, a thermoresponsive stomatocyte was generated, where the opening narrowed and irreversibly closed with a slight increase in the temperature. Detailed transmission electron microscopy analysis reveals the formation of both closed and fused stomatocytes upon heating the sample above the critical solution temperature of PiPrOx.

Beyond Skin Deep: Phospholipid-Based Nanovesicles as Game-Changers in Transdermal Drug Delivery.

Transdermal administration techniques have gained popularity due to their advantages over oral and parenteral methods. Noninvasive, self-administered delivery devices improve patient compliance and control drug release. Transdermal delivery devices struggle with the skin's barrier function. Molecules over 500 Dalton (Da) and ionized compounds don't permeate through the skin. Drug encapsulation in phospholipid-based vesicular systems is the most effective skin delivery technique. Vesicular carriers include bi-layered liposomes, ultra-deformable liposomes, ethanolic liposomes, transethosomes, and invasomes. These technologies enhance skin drug permeation by increasing formula solubilization, partitioning into the skin, and fluidizing the lipid barrier. Phospholipid-based delivery systems are safe and efficient, making them a promising pharmaceutical and cosmeceutical drug delivery technique. Still, making delivery systems requires knowledge about the physicochemical properties of the drug and carrier, manufacturing and process variables, skin delivery mechanisms, technological advances, constraints, and regulatory requirements. Consequently, this review covers recent research achievements addressing the mentioned concerns.

Development of a novel SupraChoroidal-to-Optic-NervE (SCONE) drug delivery system

Purpose Targeted drug delivery to the optic nerve head may be useful in the preclinical study and later clinical management of optic neuropathies, however, there are no FDA-approved drug delivery systems to achieve this. The purpose of this work was to develop an optic nerve head drug delivery technique. Methods Different strategies to approach the optic nerve head were investigated, including standard intravitreal and retroorbital injections. A novel SupraChoroidal-to-Optic-NervE (SCONE) delivery was optimized by creating a sclerotomy and introducing a catheter into the suprachoroidal space. Under direct visualization, the catheter was guided to the optic nerve head. India ink was injected. The suprachoroidal approach was performed in New Zealand White rabbit eyes in vivo (25 animals total). Parameters, including microneedle size and design, catheter design, and catheter tip angle, were optimized ex vivo and in vivo. Results Out of the candidate optic nerve head approaches, intravitreal, retroorbital, and suprachoroidal approaches were able to localize India ink to within 2 mm of the optic nerve. The suprachoroidal approach was further investigated, and after optimization, was able to deposit India ink directly within the optic nerve head in up to 80% of attempts. In eyes with successful SCONE delivery, latency and amplitude of visual evoked potentials was not different than the naïve untreated eye. Conclusions SCONE delivery can be used for targeted drug delivery to the optic nerve head of rabbits without measurable toxicity measured anatomically or functionally. Successful development of this system may yield novel opportunities to study optic nerve head-specific drug delivery in animal models, and paradigm-shifting management strategies for treating optic neuropathies. Translational Relevance Here we demonstrate data on a new method for targeted delivery to the optic nerve head, addressing a significant unmet need in therapeutics for optic neuropathies.

Novel approaches to pharmaceutical delivery, including nanostructures and liposomes, may bring about substantial changes in the way breast cancer is managed. These systems offer a multitude of advantages, such as heightened bioavailability, enhanced solubility, targeted tumor destruction, and diminished adverse effects. The application of nano-drug delivery systems to administer anti-breast cancer medications is a significant subject of research. This article delves into the domain of breast cancer, conventional treatment methods, the incorporation of nanotechnology into managerial tactics, and strategic approaches aimed at tackling the disease at its core.

Thermal analysis of AIN-Al2O3 Casson hybrid nano fluid flow through porous media with inclusion of slip impact

A mathematical analysis of magnetized Casson hybrid nanofluid flow over a stretching permeable sheet with porosity effects and being exposed to thermal convective boundary conditions with slip in velocity and concentration have been presented numerically. The attained steady-state partial differential equations are highly coupled and nonlinear in nature and are not agreeable to any of the direct techniques. Hence, they are being reduced to coupled-nonlinear ordinary differential equations by means of appropriate similarity transformations. A MATLAB-based, bvp4c scheme has been employed to obtain numerical solutions. Suitable graphs have been plotted which demonstrates the fluid flow velocity, temperature, concentration and micro-organism distribution fields in the boundary layer regime. Magnifying Casson fluid parameter and porosity leads to a decline in the velocity field. Amplifying the concentration slip decays the concentration profile. A comparative analysis was conducted to confirm the findings from previous research, demonstrating strong consistency with the results previously documented. Enhancing heat transfer in microelectromechanical systems (MEMS), optimizing medical drug delivery techniques, and boosting the efficiency of cooling systems in industrial processes are all potential applications of this study.
