Abstract
INTRODUCTION Percutaneous drug delivery systems are attractive not only as a therapeutic strategy but also for cosmetic treatment. Iontophoresis is a well-recognized method for promoting transdermal absorption of ionized compounds. Franz cells are generally used to estimate drug permeation of skin by iontophoresis. However, methods using Franz cells are less versatile; for instance, the method is unsuited for use with a portable electric facial care device having a working probe of a certain size and weight. In this study, we constructed a semi-dry apparatus for use with an electric facial care device. METHODS The apparatus has a multilayer structure consisting of mouse skin and 3 filter papers, modeled after the Franz cell. The skin permeation of the drug edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one) was then measured using this apparatus. RESULTS Edaravone permeation depended on working time, drug concentration, and ionization ratio of edaravone when iontophoresis was carried out with an electric facial care device. Furthermore, glycyrrhizic acid, α-tocopheryl phosphate, retinoic acid, and ascorbyl palmitate, which are recognized as functional cosmetic materials, also permeated the skin by applying iontophoresis with the device. CONCLUSION These results suggest that the developed measuring apparatus is applicable for use with a portable electric facial care device and that iontophoresis using a portable electric facial care device is potentially useful in the cosmetic field.

Abstract
OBJECTIVE To review the current state of pharmaceutical treatment recommendations for the management of osteoarthritis. METHOD A narrative review was drafted to describe treatment guidelines, mechanism of action, pharmacokinetics, and toxicity for nine classes of pharmaceuticals: 1) oral nonsteroidal anti-inflammatory drugs (NSAIDs), 2) topical NSAIDs, 3) COX-2 inhibitors, 4) duloxetine, 5) intra-articular corticosteroids, 6) intra-articular hyaluronic acid, 7) acetaminophen (paracetamol), 8) tramadol, and 9) capsaicin. RESULTS In general, oral and topical NSAIDs, including COX-2 inhibitors, are strongly recommended first-line treatments for osteoarthritis due to their ability to improve pain and function but are associated with increased risks in patients with certain comorbidities (e.g., heightened cardiovascular risks). Intra-articular corticosteroid injections are generally recommended for osteoarthritis management and have relatively minor adverse effects. Other treatments, such as capsaicin, tramadol, and acetaminophen, are more controversial, and many updated guidelines offer differing recommendations. CONCLUSION The pharmaceutical management of osteoarthritis is a constantly evolving field. Promising treatments are emerging, and medicines that were once considered conventional (e.g., acetaminophen) are gradually becoming less acceptable based on concerns with efficacy and safety. Clinicians need to consider the latest evidence and recommendations to make an informed decision with their patients about how to optimize treatment plans for patients with knee, hip, polyarticular, or hand osteoarthritis.

Abstract
Dissolvable microneedles offer an attractive delivery system for transdermal drug and vaccine delivery. They are most commonly formed by filling a microneedle mold with liquid formulation using vacuum or centrifugation to overcome the constraints of surface tension and solution viscosity. Here, we demonstrate a novel microneedle fabrication method employing an atomised spray technique that minimises the effects of the liquid surface tension and viscosity when filling molds. This spray method was successfully used to fabricate dissolvable microneedles (DMN) from a wide range of sugars (trehalose, fructose and raffinose) and polymeric materials (polyvinyl alcohol, polyvinylpyrrolidone, carboxymethylcellulose, hydroxypropylmethylcellulose and sodium alginate). Fabrication by spraying produced microneedles with amorphous content using single sugar compositions. These microneedles displayed sharp tips and had complete fidelity to the master silicon template. Using a method to quantify the consistency of DMN penetration into different skin layers, we demonstrate that the material of construction significantly influenced the extent of skin penetration. We demonstrate that this spraying method can be adapted to produce novel laminate-layered as well as horizontally-layered DMN arrays. To our knowledge, this is the first report documenting the use of an atomising spray, at ambient, mild processing conditions, to create dissolvable microneedle arrays that can possess novel, laminate layering.

Abstract
Although minoxidil (MX) is a drug known to stimulate hair growth, the treatment of androgenic alopecia could be improved by delivery strategies that would favor drug accumulation into the hair follicles. This work investigated in vitro the potential of iontophoresis to achieve this objective using MX sulfate (MXS), a more water-soluble derivative of MX. Passive delivery of MXS was first determined from an ethanol-water solution and from a thermosensitive gel. The latter formulation resulted in greater accumulation of MXS in the stratum corneum (skin's outermost layer) and hair follicles and an overall decrease in absorption through the skin. Anodal iontophoresis of MXS from the same gel formulation was then investigated at pH 3.5 and pH 5.5. Compared with passive delivery, iontophoresis increased the amount of drug reaching the follicular infundibula from 120 to 600 ng per follicle. In addition, drug recovery from follicular casts was threefold higher following iontophoresis at pH 5.5 compared with that at pH 3.5. Preliminary in vivo experiments in rats confirmed that iontophoretic delivery of MXS facilitated drug accumulation in hair follicles. Overall, therefore, iontophoresis successfully and significantly enhanced follicular delivery of MX suggesting a useful opportunity for the improved treatment of alopecia.

Abstract
The objective was to relate the efficiency of a charged drug to carry current across the skin during iontophoresis to its structural and/or physicochemical properties. The corollary was the establishment of a predictive relationship useful to predict the feasibility of iontophoretic drug delivery, and for the selection and optimization of drug candidates for this route of administration. A dataset of 16 cations, for which iontophoretic fluxes have been measured under identical conditions, with no competition from exogenous co-ions, was compiled. Maximum transport numbers correlated with ion mobilities and decreased with ionic size, the dependence indicating that the electromigration mechanism of iontophoresis would become negligible for drugs of hydrodynamic radius greater than about 8 A. Validation of the model was demonstrated by successfully predicting the transport numbers of three structurally distinct dipeptides, the iontophoretic data for which had been determined under distinctly different experimental conditions. Finally, for the "training" set of cations, a strong linear dependence between their transport numbers in skin and those in aqueous solution was demonstrated; the former were larger by approximately a factor of 1.4 consistent with skin's cation permselectivity. In conclusion, this research offers a practical contribution to the development of a predictive structure-transport model of iontophoresis.

Abstract
This study evaluates the distribution profile in tissues and concentrative uptake mechanism for a cationic compound of DX-9065a in rats. After a single intravenous dosing of [(14)C]-DX-9065a to male rats, higher levels of radioactivity were observed in kidney and liver. Moreover, the radioactivity in the liver continuously increased up to 6 h after intravenous dosing and a concentrative uptake of the drug against the radioactivity gradient between plasma and liver, showing K(p) value of 90.7. In contrast, carrier-mediated systems did not play a significant role in the uptake of DX-9065a by hepatocytes. A subcellular distribution study was conducted by means of Percoll density gradient centrifugation and revealed a high affinity of the compound with the lysosomes. It was concluded that DX-9065a permeated into hepatocyte across the membrane primarily by passive diffusion, and the consequent process of lysosomal trapping played a major role in the concentrative uptake of the drug into the liver.

Abstract
Permeability is an underlying parameter to control drug absorption. For highly water-soluble drugs, the high correlation between their permeability and fraction absorbed in humans is reported. In the present study, to predict the absorbability of poorly water-soluble drugs in humans, a new experimental method of the permeation study was proposed and subjected to examination. Firstly, using the in vitro chamber method modified to contain 5% (final concentration) dimethyl sulufoxide (DMSO) in both compartments of the chamber (DMSO-MS), the effect of DMSO on membrane integrity was evaluated. Secondly, the correlation between the apparent permeability coefficients (Papp) obtained through DMSO-M or DMSO-MS and fractions absorbed in humans were investigated using 7 poorly water-soluble drugs. Membrane integrity of the rat intestinal tissues was maintained after using DMSO-MS, as with that after using the conventional in vitro chamber method. Papp of two paracellular markers obtained through DMSO-MS was not different from that obtained through the conventional chamber method. In the permeation study of the P-glycoprotein substrate, Papp from both mucosal to serosal and serosal to mucosal sides obtained through DMSO-MS was not significantly different from that obtained through the conventional chamber method. The correlation between Papp obtained through DMSO-MS and Fa which was expressed by the equation of Fa=1-exp (-Pappx1.38x10(5)) (r2=0.980), was more favorable than the correlation between Papp obtained through DMSO-M and Fa which was expressed by the equation of Fa=1-exp (-Pappx2.12x10(5)) (r2=0.875). These results showed that DMSO-MS was a useful method for predicting the absorbability of poorly water-soluble drugs.

Abstract
AIM To investigate the facilitative role of iontophoresis in drug delivery through intact and caries-affected dentine into the pulp. METHODOLOGY Forty-eight intact dentine or caries-affected dentine discs were prepared from freshly extracted human third molars. The hydraulic conductance was measured before and after the experiments. Drug diffusion with and without iontophoresis (0.05 mA, 10 min) was evaluated using a split-chamber device. The enamel side chamber was filled with metronidazole (MN), sodium salicylate (SS) or naproxen sodium (NA), while the pulpal side was circulated with phosphate buffered saline (PBS) and pressurized (15 cmH2O). Samples were collected after 1 h. Drug concentrations of the pulpal side solution were determined using a spectrophotometer. Then, electrical impedance of each dentine disc was measured. Finally, the dentine disc surfaces were observed by scanning electron microscopy. RESULTS Drug diffusion was significantly influenced by iontophoresis, caries-induced changes in dentine and the drugs used (three-way anova, P < 0.05). The diffusion of all the drugs through caries-affected dentine was significantly less than that through intact dentine (independent t-test, P < 0.05). Also, iontophoresis facilitated the diffusion of all the drugs through intact and caries-affected dentine. The drug diffusion of SS was significantly higher than MN and NA (one-way anova, P < 0.05), independent of iontophoresis. CONCLUSIONS Presence of dental caries may inhibit drug diffusion through dentine into the pulp. However, iontophoresis could enhance the delivery of ionized drugs through both intact and caries-affected dentine.

Abstract
The objective of this study was to investigate the relationship between drug lipophilicity and the transdermal absorption processes in the iontophoretic delivery in vivo. Anodal iontophoresis of beta-blockers as model drugs having different lipophilicity (atenolol, pindolol, metoprolol, acebutolol, oxprenolol and propranolol) was performed with rats (electrical current, 0.625 mA/cm2; application period, 90 min), and the drug concentrations in skin, cutaneous vein and systemic vein were determined. Increasing the lipophilicity of beta-blockers caused a greater absorption into the skin. Exceptionally, it was found that pindolol had high skin absorption, irrespective of its hydrophilic nature. Further, the drug transfer rate from skin to cutaneous vein (R(SC)) was evaluated from the arterio-venous plasma concentration difference of drug in the skin. Normalized R(SC) by skin concentration showed a negative correlation with the logarithm of n-octanol/buffer partition coefficient (Log P, pH 7.4), suggesting the partitioning between stratum corneum and viable epidermis was a primary process to determine the transfer properties of beta-blockers to local blood circulation. Pindolol exhibited both high skin absorption and high transfer from skin to cutaneous vein. These characteristics of pindolol could be explained by the chemical structure, molecular size and hydrophilicity. These findings for pindolol should be valuable for the optimal design of drug candidates for iontophoretic transdermal delivery.
