Abstract
Fluconazole (FLZ) has been widely used in the treatment of infection caused by Candida albicans, including the treatment of vulvovaginal candidiasis (VVC). However, when delivered orally, FLZ faces numerous limitations due to its poor solubility and undergoes the symptoms of first-pass metabolism. In this study, we developed the combinatorial approach of nanocrystals (NCs) and dissolving microneedles (DMNs) for effective local vaginal delivery of FLZ. The formulation containing 1.0% w/v PVA as stabilizer with 12 h of milling time process was found to be an optimal combination to fabricate FLZ as NCs (FLZ-NCs) with optimum size particle and PDI value (less than 0.25). Furthermore, the in vitro release study also showed a superior percentage of FLZ release up to 89.51 ± 7.52%. In combination with the DMNs, the FLZ recovery was 96.45 ± 2.38% with the insertion percentage in average of 76.14 ± 2.28% and height decreased percentage was only 7.53 ± 0.56%. Moreover, the ex vivo investigation and anti-candidiasis activity of DMNs-FLZ-NCs in vaginal model showed better results compared to other conventional preparations, such as film patch and hydrogel containing FLZ.

Abstract
Sildenafil citrate (SIL) as a first-line treatment for erectile dysfunction is currently reported to have poor solubility and bioavailability. Moreover, SIL undergoes first-pass metabolism when taken orally and its injection can lead to discomfort. In this study, we introduce a novel transdermal delivery system that integrates hydrogel-forming microneedles with the inclusion complex tablet reservoir. The hydrogel-forming microneedle was prepared from a mixture of polymers and crosslinkers through a crosslinking process. Importantly, the formulations showed high swelling capacity (>400 %) and exhibited adequate mechanical and penetration properties (needle height reduction < 10 %), penetrating up to five layers of Parafilm® M (assessed to reach the dermis layer). Furthermore, to improve the solubility of SIL in the reservoir, the SIL was pre-complexed with β-cyclodextrin. Molecular docking analysis showed that SIL was successfully encapsulated into the β-cyclodextrin cavity and was the most suitable conformation compared to other CD derivatives. Moreover, to maximize SIL delivery, sodium starch glycolate was also added to the reservoir formulation. As a proof of concept, in vivo studies demonstrated the effectiveness of this concept, resulting in a significant increase in AUC (area under the curve) compared to that obtained after administration of pure SIL oral suspension, inclusion complex, and Viagra® with relative bioavailability > 100 %. Therefore, the approach developed in this study could potentially increase the efficacy of SIL in treating erectile dysfunction by being non-invasive, safe, avoiding first-pass metabolism, and increasing drug bioavailability.

Abstract
Telmisartan (TMN), an angiotensin receptor blocker (ARB) drug, is being considered as an alternative therapy for Alzheimer's disease (ALZ). However, when taken orally, its low water solubility leads to a low bioavailability and brain concentration. To overcome this problem, TMN was formulated as nanocrystals (NC), then incorporated into dissolving microneedles (DMN) to enhance drug delivery to the brain via the trigeminal route on the face. TMN-NC was formulated with 1% PVA using the top-down method and stirred for 12 h, producing the smallest particle size of 132 ± 11 nm and showing a better release profile, reaching 89.51 ± 7.52% (2 times greater than pure TMN). TMN-NC-DMN with a combination of 15% PVA and 25% PVP showed optimal mechanical strength and penetration ability; they could dissolve completely within 15 min, and their surface pH was safe for the skin. The permeation test of TMN-NC-DMN showed the highest concentration, reaching 285.80 ± 32.12 μg/mL, compared to TMN-DMN and patch control, which only reached 87.17 ± 11.24 and 94.00 ± 11.09 μg/mL, respectively. The TMN-NC-DMN combination showed better bioavailability and was found to be well-delivered to the brain without any irritation to the skin. Pharmacokinetic parameters had a significant difference (p > 0.05) compared to other preparations, making it a promising treatment for ALZ.

Abstract
The aim of this study was to develop and evaluate the transdermal patch formulations of nifedipine. The patch formulations containing nifedipine were prepared and optimized with different ratios of vinyl and cellulose-derived polymers, drug contents, and permeation enhancers. Among the various formulations, the patch formulation containing a 1:5 ratio of ethyl cellulose and polyvinyl pyrrolidone was selected for ex vivo pharmacokinetic study based on in vitro permeation studies using stratum corneum of the pig's skin. The cumulative percentage release after the transdermal administration of the optimized patch formulation was 71.43%, and the plasma concentration of nifedipine was maintained for 16 hrs. The physicochemical evaluation study including flatness, thickness, moisture content and uptake, drug content in vitro release, and ex vivo permeation indicated satisfactory results. The formulation batch with clove oil as a penetration enhancer has shown better ex vivo permeation as compared to the formulations without enhancers and another synthetic enhancer. These results suggest that the optimized patch formulation Q3 could be further developed for clinical applications, providing the therapeutic plasma level of nifedipine over an extended period. Hence analyzing the results of the evaluation tests, in vitro and ex vivo data on the preparation and optimization of nifedipine-loaded transdermal patch, it can be concluded that the formulation shows its feasibility as an effective transdermal delivery system for nifedipine.

Abstract
Telmisartan (TEL) is a promising antihypertensive agent among other angiotensin receptor blockers. However, its oral application is limited by its poor water solubility. This study presents the successful utilization of biomaterial-based hydrogel-forming microneedles integrated with a direct compressed tablet reservoir (HFMN-DCT) for the transdermal delivery of telmisartan in the treatment of hypertension. The combination of PVP, PVA, and tartaric acid was used in the HFMN formulation. A range of cross-linking temperatures and times were employed to optimize the characteristics of the HFMN. The HFMN exhibited excellent swelling capacity, mechanical strength, and insertion properties. Additionally, the poorly soluble characteristic of TEL was improved by the inclusion complex formulation with β-cyclodextrin (βCD). Phase solubility analysis showed an Ap-type diagram, indicating a higher-order complex between TEL and βCD, with respect to βCD. A ratio of TEL:βCD of 1:4 mM demonstrates the highest solubility enhancement of TEL. The inclusion complex formation was confirmed by FTIR, XRD, DSC, and molecular docking studies. A significantly higher release of TEL (up to 20-fold) from the inclusion complex was observed in the in vitro release study. Subsequently, a DCT reservoir was developed using various concentrations of sodium starch glycolate. Essentially, both the HFMN and DCT reservoir exhibit hemocompatibility and did not induce any skin irritation. The optimized combination of the HFMN-DCT reservoir showed an ex vivo permeation profile of 83.275 ± 2.405%. Notably, the proposed system showed superior pharmacokinetic profiles in the in vivo investigation using male Wistar rats. Overall, this study highlights the potential of HFMN-DCT reservoir systems as a versatile platform for transdermal drug delivery applications.

Abstract
Ustukhuddūs (Lavandula stoechas L.) has been extensively used orally and topically in treating various neurological disorders, including dementia. The optimum potential of traditional dosage forms of Ustukhuddūs is limited for various reasons. Transdermal drug delivery system (TDDS) is a novel means of drug delivery and is known to overcome the drawbacks associated with traditional dosage forms. The current study aimed at fabricating and evaluating Ustukhuddūs hydro-alcoholic extract (UHAE) and essential oil (UEO) loaded matrix-type transdermal patches having a combination of hydrophilic - hydroxyl propyl methyl cellulose (HPMC) and hydrophobic - ethyl cellulose (EC) polymers. ATR-FTIR, DSC, XRD, and SEM analysis were carried out to study drug-polymer interactions, confirming the formation of developed patches and drug compatibility with excipients. We assessed the fabricated patches to evaluate their physicochemical properties, in vitro drug release, and permeation characteristics via ex vivo experiments. The physicochemical characteristics of patches showcased the development of good and stable films with clarity, smoothness, homogeneity, optimum flexibility and free from causing skin irritancy or sensitization. In vitro drug release and ex vivo permeation profile of developed patches were evaluated employing Franz diffusion cells. UHAE and UEO patches exhibited a cumulative drug release of 81.61 and 85.24 %, respectively, in a sustained-release manner and followed non-Fickian release mechanisms. The ex vivo permeation data revealed 66.82 % and 76.41 % of drug permeated from UHAE and UEO patches, respectively. The current research suggests that the formulated patches are more suitable for TDDS and hold potential significance in the treatment of dementia, contributing to enhanced patient compliance, thereby highlighting the implication of Unani Medicine in Nisyan (Dementia) treatment.

Abstract
Pravastatin sodium (PVS) is a hypolipidemic drug with poor oral bioavailability due to the first-pass effect. Therefore, this study aims to formulate and evaluate transdermal patches containing PVS-loaded nanoemulsions (PVS-NEs) to increase PVS's hypolipidemic and hepatoprotective activities. PVS-NEs were prepared using the aqueous titration method, where oleic acid was chosen as an oil phase, and span 80 and tween 80 were used as surfactant and cosurfactant respectively. Droplet size (DS), polydispersity index (PDI), zeta potential (ZP), clarity, and thermodynamic stability of NEs were all characterized. Also, PVS-NEs (NE2) with 50% oil phase, 40% SC mix 2:1, and 10% water were selected as an optimum formula based on the results of DS (251 ± 16), PDI (0.4 ± 0.16), and ZP (-70 ± 10.4) to be incorporated into a transdermal patch, and PVS-NE2 loaded transdermal patches (PVS-NE2-TDPs) were prepared by solvent evaporation method. F1 patch with HPMC E15 and PVP K30 in a ratio of 3:1 represented satisfactory patch properties with good drug-excipients compatibility. Thus, it was selected as an optimum patch formula. The optimized F1 patch was characterized for thickness, moisture content, weight variation, and drug-excipients incompatibility. Therefore, it was subjected to ex vivo skin permeation and finally pharmacodynamic studies. Ex vivo permeation studies of F1 revealed that the cumulative amount of PVS permeated across rat skin was 271.66 ± 19 µg/cm2 in 72 h, and the pharmacodynamic studies demonstrated that the F1 patch was more effective in treating hyperlipidemia than PVS-TDP (control patch) based on both blood analysis and histopathological examination. .

Abstract
The objective of our study, which combined API-ILs strategy and controlled-release polymers, was to prepare a 72 h long-acting drug-in-adhesive patch for optimum delivery of asenapine (ASE). Special attention was paid to the permeation promotion mechanism and the controlled release behavior of ASE-ILs in pressure sensitive adhesives (PSA). Formulation factors were investigated by ex vivo transdermal experiments. The optimized patch was evaluated by pharmacokinetics study and skin irritation test. The obtained formulation was as follows, 15% w/w ASE-MA (about 1136 μg/cm2 ASE, 413 μg/cm2 MA), AACONH2 (Amide adhesive) as the matrix, 80 μm thickness, backing film of CoTran™ 9733. The optimized patch displayed satisfactory ex vivo and in vivo performance with Q 72 h of 620 ± 44 µg/cm2 and Fabs of 62.4%, which utilization rate (54.6%) was significantly higher than the control group (38.3%). By using the classical shake flask method, 13C NMR, DSC, and FTIR, the physicochemical properties and structure of ILs were characterized. log Do/w, ATR-FTIR, Raman, and molecular dynamics simulation results confirmed that ASE-MA (MA: 3-Methoxypropionic acid) had appropriate lipophilicity, and affected lipid fluidity as well as the conformation of keratin to improve the skin permeation. The FTIR, MDSC, rheology, and molecular docking results revealed that hydrogen bond (H-bond), were formed between ASE-MA and PSA, and the drug increased the molecular mobility of polymer chains. In summary, the 72 h long-acting patch of ASE was successfully prepared and it supplied a reference for the design of long-acting patches with ASE.

Abstract
Vulvovaginal candidiasis (VVC) is a vaginal infection caused by abnormal growth of Candida sp., especially Candida albicans, in the vaginal mucosa. A shift in vaginal microbiota is prominent in VVC. The presence of Lactobacillus plays a vital role in maintaining vaginal health. However, several studies have reported resistance of Candida sp. against azoles drugs, which is recommended as VVC treatment. The use of L. plantarum as a probiotic would be an alternative to treat VVC. In order to exert their therapeutic activity, the probiotics needed to remain viable. Multilayer double emulsion was formulated to obtain L. plantarum loaded microcapsules (MCs), thus improving its viability. Furthermore, a vaginal drug delivery system using dissolving microneedles (DMNs) for VVC treatment was developed for the first time. These DMNs showed sufficient mechanical and insertion properties, dissolved rapidly upon insertion, facilitating probiotic release. All formulations proved non-irritating, non-toxic, and safe to apply on the vaginal mucosa. Essentially, the DMNs could inhibit the growth of Candida albicans up to 3-fold than hydrogel and patch dosage forms in ex vivo infection model. Therefore, this study successfully developed the formulation of L. plantarum-loaded MCs with multilayer double emulsion and its combination in DMNs for vaginal delivery to treat VVC.

Abstract
The recent Covid-19 pandemics led to the increased use of facial masks, which can cause skin lesions due to continuous pressure, tension and friction forces on the skin. A preventive approach is the inclusion of dressings between the face and the mask. However, there are still uncertainties about the protective effect of dressings and whether their use compromises the efficiency of masks. The current study aimed to develop and test the efficacy of a gelatin-based hydrogel patch to be placed between the mask and the facial area. Design of Experiment with a Quality by Design approach tools were used in the patch development and in vitro characterization was performed through rheological evaluation, ATR-FTIR and molecular docking studies. Furthermore, tribology studies were performed to test the patch performance. The results showed that the addition of excipients enhanced gelation temperature, elasticity and adhesiveness parameters. The interactions between excipients were confirmed by ATR-FTIR and molecular docking. The tribology assay revealed similar friction values at room and physiological temperature, and when testing different skin types. In conclusion, the physical properties and the performance evaluation reported in this study indicate that this innovative film-forming system can be used to prevent skin lesions caused by the continuous use of protective masks.

Abstract
The treatment of infected wounds in patients with highly sensitive skin is challenging. Some of the available wound dressings cause further skin tear and bleeding upon removal thereby hindering the healing process. In this study, dissolvable antibacterial wound dressing patches loaded with cephalexin monohydrate were prepared from different amounts of sodium alginate (SA) and carboxymethyl cellulose (CMC) by the solvent casting evaporation technique. The patches displayed good tensile strength (3.83-13.83 MPa), appropriate thickness (0.09 to 0.31 mm) and good flexibility (74-98 %) suitable for the skin. The patches displayed good biodegradability and low moisture uptake suitable to prevent microbial invasion on the wound dressings upon storage. The release profile of the drug from the patches was sustained in the range of 47-80 % for 48 h, revealing their capability to inhibit bacterial infection. The biological assay showed that the patches did not induce cytotoxic effects on HaCaT cells, revealing good biocompatibility. The antimicrobial effect of the patches on the different strains of bacteria used in the study was significant. The cell migration (66.7-74.3 %) to the scratched gap was promising revealing the patches' capability to promote wound closure. The results obtained show that the wound dressings are potential materials for the treatment of infected wounds.

Abstract
Diabetes mellitus (DM) is a metabolic disorder that is one of the most common health problems in the world, primarily type 2 DM (T2DM). Metformin (MTF), as the first-line treatment of DMT2, is effective in lowering glucose levels, but its oral administration causes problems, including gastrointestinal side effects, low bioavailability, and the risk of hypoglycemia. In this study, we formulated MTF into microparticles incorporating a glucose-responsive polymer (MP-MTF-GR), which could potentially increase the bioavailability and extend and control the release of MTF according to glucose levels. This system was delivered by dissolving microneedles (MP-MTF-GR-DMN), applied through the skin, thereby preventing gastrointestinal side effects of orally administered MTF. MP-MTF-GR was formulated using various concentrations of gelatin as a polymer combined with phenylboronic acid (PBA) as a glucose-responsive material. MP-MTF-GR was encapsulated in DMN using polyvinyl pyrrolidone (PVP) and polyvinyl alcohol (PVA) as DMN polymers. The physicochemical evaluation of MP-MTF-GR showed that MTF could be completely entrapped in MP with the percentage of MTF trapped increasing with increasing gelatin concentration without changing the chemical structure of MTF and producing stable MP. In addition, the results of the physicochemical evaluation of MP-MTF-GR-DMN showed that DMN had adequate mechanical strength properties and penetration ability and was stable to environmental changes. The results of the in vitro release and ex vivo permeation study on media with various concentrations of glucose showed that the release and permeation of MTF from the formula increased with increasing glucose levels in the media. The MP-MTF-GR-DMN formula successfully delivered MTF through the skin at 11.30 ± 0.29, 23.31 ± 1.64, 36.12 ± 3.77, and 53.09 ± 3.01 μg from PBS, PBS + glucose 1%, PBS + glucose 2%, and PBS + glucose 4%, respectively, at 24 h, which indicates glucose-responsive permeation and release behavior. The formula developed was also proven to be nontoxic based on hemolysis tests. Importantly, the in vivo study on the rat model showed that this combination approach could provide a better glucose reduction compared to other routes, reducing the blood glucose level to normal levels after 3 h and maintaining this level for 8 h. Furthermore, this approach did not change the skin moisture of the rats. This MP-MTF-GR-DMN is a promising alternative to MTF delivery to overcome MTF problems and increase the effectiveness of T2DM therapy.

Abstract
Resveratrol (RVT) is a polyphenolic phytoestrogen which has shown antiproliferative activity in breast cancer. However, its low bioavailability and short half-life have restricted its use. The current study aimed to develop transdermal patches of RVT and evaluate its site-specific delivery for breast cancer therapy. Different penetration enhancers were screened using a computational tool, quantitative structure propery relationship (QSPR). The best permeation of RVT was observed in a patch comprising hydroxypropyl methylcellulose (HPMC) E15LV: HPMC-K4M: polyvinyl pyrrolidone (PVP) K30 in the ratio of 3:1:2 as release controlling polymers with Glycerol:Capryol 90 (4:1) as penetration enhancer and plasticizer. To assess the localized delivery of RVT, the patch was applied to the breast of female rats. Higher breast tissue disposition with lower systemic concentration was observed compared to oral administration, demonstrated by increased AUC and MRT. Further, the optimized RVT patches were tested in 7,12-Dimethylbenz[a]anthracene (DMBA) induced rat mammary cancer. Compared to oral RVT, the application of RVT tansdermal patches significantly reduced the tumor volume and serum CA 15-3, a cancer biomarker. Thus, the RVT transdermal patch may be a viable approach for ensuring high local concentration of drug for site-specific delivery in breast cancer therapy.

Abstract
AbstractDuring storage, duloxetine hydrochloride may have an unexpected cross reaction with enteric coated acrylic resin, which may affect the product quality. Solve the problem of cross-reaction between the Duloxetine enteric-coated tablets core and coated enteric materials and improve the quality of the products. Duloxetine enteric-coated tablets’ core formulation and isolation layer prescription were designed and compared with duloxetine enteric-coated tablets sold on the market. Then, we measured the dissolution rate, content, and releasing rate of prepared duloxetine enteric-coated tablets. In the formulation of tablets core, prescription 3 had advantages in particle mobility, disintegration time, and dissolution rate. Prescription 5 was stable during the coating process, and the dissolution residue in the cup was relatively good, showing obvious dissolution advantages. Thus, prescription 5 was selected as the isolation layer prescription. The most suitable adhesive for the preparation of Duloxetine hydrochloride enteric-coated tablets was povione K30 dissolved in ethanol solution with 1/2 of the prescription amount. When 1.3 g colloidal silica was added to the prescription and the dosage of magnesium stearate was 1.48 g, the dissolution rate of the drug could be relatively improved. The ratio of sucrose and talc was 138/8.7, which could effectively configure the coating solution with a solid content of 15–20% to make the coating smooth.

Abstract
The skin is a complex layer system and the most important barrier between the environment and the organism. In this review, we describe some widespread skin problems, with a focus on eczema, which are affecting more and more people all over the world. Most of treatment methods for atopic dermatitis (AD) are focused on increasing skin moisture and protecting from bacterial infection and external irritation. Topical and transdermal treatments have specific requirements for drug delivery. Breathability, flexibility, good mechanical properties, biocompatibility, and efficacy are important for the patches used for skin. Up to today, electrospun fibers are mostly used for wound dressing. Their properties, however, meet the requirements for skin patches for the treatment of AD. Active agents can be incorporated into fibers by blending, coaxial or side-by-side electrospinning, and also by physical absorption post-processing. Drug release from the electrospun membranes is affected by drug and polymer properties and the technique used to combine them into the patch. We describe in detail the in vitro release mechanisms, parameters affecting the drug transport, and their kinetics, including theoretical approaches. In addition, we present the current research on skin patch design. This review summarizes the current extensive know-how on electrospun fibers as skin drug delivery systems, while underlining the advantages in their prospective use as patches for atopic dermatitis.

Abstract
Purpose Halloysite nanotubes (HNTs) are a versatile and highly investigated clay mineral due to their natural availability, low cost, strong mechanical strength, biocompatibility, and binding properties. The present work explores its role for retarding and controlling the drug release from the composite polymer matrix material. Methods For this purpose, nanocomposite films comprising propranolol HCl and different concentrations of HNTs were formulated using the “solution casting method”. The menthol in a concentration of 1% w/v was used as a permeation enhancer, and its effect on release and permeation was also determined. Quality characteristics of the nanocomposite were determined, and in vitro release and permeation studies were performed using the Franz diffusion system. The data was analyzed using various mathematical models and permeation parameters. Optimized formulation was also subjected to skin irritation test, FTIR, DSC, and SEM study. Systemic absorption and disposition of propranolol HCl from the nanocomposites were predicted using the GastroPlus TCAT® model. Results The control in drug release rate was associated with the higher concentration of HNTs. F8 released 50% of propranolol within 8 hours (drug, HNTs ratio, 1:2). The optimized formulation (F6) with drug: HNTs (2:1), exhibited drug release 80% in 4 hours, with maximum flux of 145.812 µg/cm2hr. The optimized formulation was found to be a non-irritant for skin with a shelf life of 35.46 months (28–30 ℃). The in silico model predicted Cmax, Tmax, AUCt, and AUCinf as 32.113 ng/mL, 16.58 h, 942.34 ng/mL×h, and 1102.9 ng/mL×h, respectively. Conclusion The study demonstrated that HNTs could be effectively used as rate controlling agent in matrix type transdermal formulations.

Abstract
The current study aimed to develop and evaluate a sustained-release transdermal Glipizide (GLP) film to overcome its oral administration problems. Chitosan (CS)-coated deformable liposomes (DLs) were utilized to enhance the drug transdermal delivery. The formulations were characterized in terms of particle size, zeta potential, entrapment efficiency (EE%), vesicle deformability, morphology, stability, and in vitro release. Transdermal films of chosen formulations were prepared by the solvent casting technique, and an ex vivo study throughout rat skin was also performed. Moreover, a pharmacokinetics (PK) study was carried out and blood glucose levels were estimated. All the liposomes were in the nanometer range and a high EE% was obtained from DLs compared to conventional liposomes (CL). The prepared formulations showed a high stability and the DLs exhibited a high deformability compared to CL. The in vitro release study confirmed the sustained release of GLP from both CL and DL and a more pronounced sustained release of GLP was detected after coating with CS. Moreover, GLP was shown to efficiently permeate through the rat skin from transdermal films by an ex vivo permeation test. The transdermal films showed a promising PK profile in the rat as compared with oral GLP. Most importantly, GLP-CS-DL1 demonstrated a higher hypoglycemic effect, confirming the possibility of systemic action by the local topical delivery of GLP.

Abstract
Topical patches containing 5-fluorouracil (5-FU) are a feasible alternative to overcome the shortcomings of commercial cream for the treatment of non-melanoma skin cancer (NMSC). Plasticizers are a critical component of drug-in-adhesive (DIA) patches as they can significantly affect the mechanical, adhesive and drug release characteristics of the patches. Eudragit® E (EuE) is a methacrylate-based cationic copolymer capable of producing flexible and adhesive films for topical application. In this study, the effect of plasticizers on the mechanical, adhesive and 5-FU release characteristics of EuE-based patches was comprehensively evaluated. While the elongation at break (%) and adhesion of the films were significantly increased with increasing triacetin, dibutyl sebacate (DBS) and triethyl citrate (TEC) concentrations, the tensile strength showed an inverse relationship. EuE plasticized with 40% triacetin, 30% DBS or 40% w/w TEC produced elastic and adhesive films most suitable for topical application. In vitro release studies of the 5-FU-loaded patches demonstrated an initial burst release pattern during the first 10 min followed by a slow release over 120 min. In summary, this study provides important information on effect of plasticizers for preparation of EuE-based patches with desired mechanical, adhesive and release characteristics of 5-FU towards their potential application in the treatment of NMSC.

Abstract
Background
A double-layer transdermal drug-in-adhesive patch of carvedilol was developed using functional and nonfunctional grades of acrylic adhesives, DURO-TAK® 387-2051, DURO-TAK® 387-2510, and DURO-TAK® 87-4098. The patch was designed to provide adequate permeation of the drug up to 2 days, with effective adhesion attributes. An optimized formulation was selected, the effect of the combination was studied and a 180° peel strength test was performed to evaluate adhesive properties. Further, the patch was assessed for in vivo studies on basis of biochemical parameters, skin irritation, and stability studies. The stability study was carried out on optimized fresh (S1) and 6 months old patches stored at room, and accelerated condition (40 ± 2 °C/75 ± 5% RH) using FTIR, DSC, and SEM techniques.
Result
It was studied that the steady-state flux (Jss) or permeation rate of the drug through excised rat skin has relied on the nature of acrylic and the combination of acrylic polymers. The TDDS containing –OH functional group DT 387-2510 with nonfunctional pressure-sensitive adhesives (PSAs) DT 87-4098, with Span 80 as penetration enhancer exhibited maximum flux (19.12 ± 0.64 μg/cm2/h) and form homogeneous and stable blends, controlling permeation of drug at a desired steady rate for 48 h. The data obtained from in vivo studies using biochemical parameters suggested that there were no statistical differences observed in results for the control and treated group while analyzing observations for serum creatinine, glucose test, sodium test, albumin, and potassium (p > 0.05). Also, the optimized formulation showed no sign of localized reactions and was confirmed by a skin histological study indicating the formulation was safe and compatible with the skin. A significant shift of peaks was not observed in FTIR spectra and DSC thermograms of the patches after the stability period.
Conclusion
The investigation reveals that the drug-in-adhesive patch of carvedilol, by a combination of functional and nonfunctional PSAs, provides a good and effective option for controlled delivery of carvedilol. From our findings, it has been concluded that drug in the adhesive patch has been able to provide satisfactory adhesion, drug uniformity, drug permeation, marked positive biochemical results, and good stability.

Abstract
Malaria caused by various types of Plasmodium has become a global health problem. One of the drugs used as the first line of malaria therapy is primaquine (PMQ). PMQ is generally administered through the oral route. However, the use of PMQ orally could potentially cause some side effects and undergo the first-pass metabolism in the liver, reducing its effectiveness. Therefore, it is necessary to develop another drug administration route to avoid this effect. In this study, for the first time, PMQ was formulated into a transdermal patch for transdermal delivery, combined with solid microneedles, Dermaroller®. Following several optimizations, HPMC and glycerin were used as the main polymer and plasticizer, respectively. Specifically, the concentration of PEG 400 as a permeation enhancer was also optimized. The transdermal patches were evaluated for weight uniformity, thickness, surface pH, folding endurance, moisture content, moisture absorption ability, bioadhesive evaluation, and drug content recovery. PMQ release and permeation were also investigated through in vitro and ex vivo tests on rats' skin tissue. Importantly, the safety of the transdermal patch was also evaluated through in vitro hemolytic and in vivo irritation tests which were confirmed by histopathological examinations. The results showed that all formulations showed desired physical and bioadhesive properties with a folding endurance of >300 folds. The results exhibited that 31.31 ± 5.25% and 22.55 ± 4.35% of primaquine were released from transdermal patches following the in vitro and the ex vivo permeation studies. Combined with Dermaroller®, the ex vivo permeation study showed an improved permeation profile with 45.89 ± 5.00% of primaquine permeated after 24 h with a zero-order kinetic during the first 8 h. Hemolysis percentage was found to be <5%, indicating the non-toxic of this approach. Finally, the histopathology study showed that there was no severe tissue damage following the administration of our approach. Further in vivo evaluations should be performed.

Abstract
BACKGROUND: Propolis contains caffeic acid compounds, which are proven to have pharmacological effects as an anti-inflammatory. However, its effectiveness is hampered by the poor solubility of caffeic acid. Here, we report developing the nanoemulgel approach containing propolis extract as an active ingredient and oleic acid as a permeation enhancer for transdermal delivery of caffeic acid.
AIM: This study aims to determine the effect of oleic acid concentration on increasing caffeic acid permeation in the skin and obtain a nanoemulgel formula with desired physical characteristics and stability.
MATERIALS AND METHODS: Propolis was macerated with 70% ethanol; the total phenolic content was measured by ultraviolet–visible spectrophotometer, and the levels of caffeic acid in the extracts and nanoemulgel preparations were finally determined using ultra-fast liquid chromatography. Formulas were made using various concentrations of oleic acid, namely, 1.25%w/w (Formula F1); 2.5%w/w (Formula F2); 5%w/w (Formula F3), respectively; and 1.25%w/w without propolis extract (Formula F4) as a comparison.
RESULTS: The results obtained from analysis of variance statistical exhibited that the difference in oleic acid concentrations in four formulas significantly affected (p < 0.05) particle size, polydispersity index, spreadability, adhesion, freeze-thaw, permeation, and retention test. However, there was no significant difference (p > 0.05) on pH and viscosity before and after 4 weeks of storage and zeta potential test. The highest amount of permeation and retention was found in F3 and F2, respectively, and all formulas tended to follow zero-order drug release kinetics. Furthermore, the results showed that the number of percent’s permeated in a row was 3.74% (F1); 5.58% (F2); 11.67% (F3), and F2 was the formula with the most optimal retention amount with a percentage of 43.13% at 24 h.
CONCLUSION: This study shows a promising delivery system for increasing the effectiveness of natural lipophilic compounds to treat inflammation in the skin.

Abstract
CONTEXT Tofacitinib tablet is approved for the treatment of rheumatoid arthritis (RA). However, tofacitinib (Tfc) faces extensive first-pass metabolism following oral administration. AIM To develop transdermal systems of Tfc and evaluate their efficacies against RA using Freund's Complete Adjuvant immunized arthritis rat model. METHODS These systems were prepared by solvent casting method and evaluated for texture, needle strength, skin penetrability, in vitro drug release, skin permeation, stability, and in vivo anti-arthritic activity. RESULTS AND DISCUSSION Transdermal patch (TS) showed smooth texture, good mechanical strength, slow-release, and slow permeation through the skin. Microneedle array (MNS) showed good needle strength, with required skin penetrability. MNS and TS showed 95% and 24% drug release, and 82% and 12% drug permeation, respectively in 4 h. The developed systems were found to be stable for 90 days at very stressful conditions, that is, 40 ± 2 °C and 75 ± 5% RH. MNS and TS both reduced arthritic scores (at p < 0.01 and p < 0.001 level, respectively) and the level of inflammatory cytokines (at p < 0.05 and p < 0.01 level, respectively) significantly as compared to that of the drug solution (DS). MNS and TS were found to be effective in restoring histological alterations (annum, synovial hyperplasia, synovial constriction, and cartilage and articular erosions) toward normal. CONCLUSION TS and MNS were found to be stable and effective for the treatment of arthritis and hence considered a good alternative for the treatment of RA with better clinical pertinence.

Abstract
The high rise in the population suffering from depression depicts the need for improved and highly effective treatment options for this condition. Efforts to develop existing drugs into user-friendly dosage forms with a number of advantages in major depressive states, including but not limited to: sustained drug release, reduced drug dosing frequency, improved tolerance and adherence, suitability for use in diverse populations and different treatment scenarios, as well as less central nervous system side effects are required. One such non-invasive drug delivery route that could provide the aforementioned benefits in the treatment of depression is the transdermal route. A number of conventional and emerging transdermal delivery strategies have been investigated for some potent antidepressants and results depict the potential of this route as a viable means for systemic delivery of therapeutically relevant doses of the tested agents, with Emsam®, the commercially available patch of selegiline, being an evidence for the same. The investigated approaches include the formulation of transdermal patches, use of vesicular drug carriers, pro-drug approach, microemulsification, chemical as well as physical enhancement technologies. This review provides a comprehensive account of the rationale, developments made till date, scope and future prospects of delivering antidepressants via the transdermal1 route of administration.

Abstract
Purpose Duloxetine (DLX) is dual serotonin and norepinephrine reuptake inhibitor suffering from limited bioavailability (≈ 40%) due to extensive hepatic metabolism. This work aims to formulate and evaluate DLX intranasal thermoreversible cubosomal gels to enhance its bioavailability and ensure efficient brain targeting. Materials and Methods Cubo-gels were prepared by 33 central composite design with three independent factors, lipid ratio (glycerol monooleate: glycerol tripalmitate), Pluronic F127%, and Pluronic F68%. The prepared formulations were evaluated for their particle size (PS), gelling temperature (GT), entrapment efficiency (EE%), and in vitro release. The cubo-gel with the highest desirability (0.88) was chosen as the optimized formulation. DLX cubo-gel was evaluated using differential scanning calorimetry, Fourier-transform infrared spectroscopy, X-ray powder diffraction, and transmission electron microscopy. Cytotoxicity study, ex vivo permeation study and in vivo bio-distribution study were conducted to evaluate the safety and efficacy of brain targeting. Results The optimum cubo-gel was composed of 3.76 lipid ratio, 20% w/v PF127, and 5% w/v PF68. It had PS of 265.13 ± 9.85 nm, GT of 32 ± 0.05°C, EE% of 98.13 ± 0.50%, and showed controlled release behavior where 33% DLX was released within 6 hrs. The plain in situ cubo-gel had a significantly higher IC50 compared to DLX solution and DLX-loaded in situ cubo-gel. The ex vivo permeation study showed 1.27 enhancement in the drug permeation from DLX in situ cubo-gel. According to the in vivo bio-distribution study in plasma and brain, the intranasal DLX in situ cubo-gel showed a 1.96 fold improvement in brain bioavailability compared to the intranasal solution. Its BTE% and DTP% were 137.77 and 10.5, respectively, indicating efficient brain targeting after intranasal administration. Conclusion Accordingly, intranasal DLX in situ cubo-gel can be considered as an innovative nano-carrier delivery system for bioavailability enhancement and efficient brain targeting of DLX to maximize its effect.

Abstract
Background: Quercetin in combination with polyvinylpyrrolidone (PVP) was found to limit the spreading of necrosis to unaffected tissues in tuberculosis-infected mice. Therefore, we hypothesized that 3D printed medicated skin patch incorporated with a quercetin-PVP combination would provide an appropriate therapeutic drug concentration with desired sustained release profile.Research design and methods: We fabricated quercetin-PVP 40 extruded-filaments by hot-melt extrusion (HME) technique along with Eudragit® RSPO and tri-ethyl citrate and further printed it to make medicated skin patches using fused deposition modeling (FDM) based 3D Printing technology. Various characterizations were performed to optimize the 3D-printed patch formulation.Results: Patch formulation has been optimized for several characterization parameters and was further assessed using SEM, DSC, and XRD studies to confirm the conversion of crystalline quercetin into an amorphous form. Finally, the pharmacokinetic profile of an optimized patch was studied in rats showing prolonged Tmax, lowered Cmax, and reduced fluctuations in plasma concentrations till 18 days with single skin application of 3D-printed medicated patch.Conclusion: Overall data confirmed the feasibility of developing 3D printed medicated skin patches to provide plasma levels for continued 18 days in rats after a single application.

Abstract
Objective In attempt to conquer the major concerns of oral duloxetine hydrochloride (like low bioavailability, intolerable side-effects and no regeneration of demyelinated nerve fibres) for the management of chemotherapy-induced peripheral neuropathy (CIPN), an alternative delivery of duloxetine hydrochloride was aimed for in-vivo optimization. Methods A film forming dermal gel consisting of duloxetine hydrochloride was formulated and enriched with methylcobalamin and geranium oil. The formulated gel successfully qualified the various pharmaceutical characteristics of gel. Administration of paclitaxel (8 mg/kg/i.p. in four divided doses) for 4 alternate days induced the symptoms of peripheral neuropathy in rats. On 14th day, the responses to noxious stimulus (mechanical hyperalgesia, cold allodynia, and heat hyperalgesia) were increased and reached to its maximum. Thereafter, drug treatment with formulated dermal gel and oral duloxetine hydrochloride (30 mg/kg, once daily) was initiated for 2 weeks in different group of animals. On the 28th day animals were sacrificed to isolate sciatic nerve, to assess biochemical changes (TBARS, reduced GSH, total protein, TNF-α, IL-6) and for histopathological examinations of nerve sections using Hematoxylin-Eosin and Toludine blue staining methods. Results Application of formulated dermal gel to paclitaxel-treated rats significantly improved paw-withdrawal latency responses during noxious stimulus testing, reduced the levels of TBARS, TNF-α, IL-6 and elevated the levels of reduced GSH as compared to paclitaxel treated rats. Histographs also indicated marked regeneration of the damaged nerve fibers. Topical delivery of duloxetine hydrochloride produced similar results in disparity to oral route. However, no significant disparity in responses was obtained with twice application of formulated dermal gel when compared to once daily application. Conclusion Tremendous recovery from nociception, oxidation and inflammation in addition to nerve degeneration was achieved through dermal application of duloxetine hydrochloride in peripheral neuropathy.

Abstract
Aim: The aim of this work was to develop buccoadhesive tablets for the systemic delivery of duloxetine HCl (DXT) using more soluble derivatives of β-cyclodextrin, i.e. hydroxypropyl-β-cyclodextrin (HPβCD) and sulfobutylether-β-cyclodextrin (SBEβCD) and to investigate enhanced cellular uptake of inclusion complexed drug.Materials and methods: Freeze dried and spray dried complexes of both cyclodextrin derivatives with DXT (1:1 molar) were prepared and characterized with DSC, FTIR, and PXRD techniques. C971 and PC, on the basis of swelling behavior, erosion and in vitro residence time, were selected for further study at different levels (-1, 0, +1) to optimize the formulation in terms of enhanced drug release and ex vivo permeation.Results: SBEβCD based complexes show more aqueous solubility of DXT (0.782 and 0.958 mM) and more complexation efficiency compared to HPβCD at 25 °C and 37 °C, respectively. Apparent stability constant was reported to be higher (1109.94 and 1693.25 M-1) for DXT-SBEβCD at 25 °C and 37 °C, respectively, than the corresponding values for DXT-HPβCD systems. Enhanced cellular uptake using fibroblast cells was revealed for complexed drug compared to free drug .Conclusion: Both cyclodextrin derivatives are able to enhance drug release and permeation in vitro and ex vivo.

Abstract
Dapoxetine (DPX) is an orally administered drug for the treatment of premature ejaculation (PE). One of the challenges of administering DPX orally as a tablet is its poor bioavailability (ie, 42%) due to extensive first-pass metabolism. Thus, it is vital to develop a new formulation and mode of delivery to achieve the unmet needs of PE treatment. In this study, an optimized DPX polymeric nanoparticle (PNP) was developed and subsequently loaded into a transdermal film. The Box–Behnken design was utilized to optimize 3 formulation factors affecting the particle size and entrapment efficiency (EE) of chitosan (CS)-alginate (ALG) PNPs. A 3-level factorial design was used to study the effect of 2 variables affecting DPX cumulative percent released and percent elongation from transdermal films loaded with DPX-PNPs. Permeation parameters were calculated following ex vivo permeation study through rat skin. Transport of the PNPs across the skin layers was investigated using a fluorescence laser microscope. Results revealed that an optimized PNPs formulation was developed with a particle size 415.94 nm and EE 37.31%. Dapoxetine was successfully entrapped in the polymeric matrix. Chitosan and ALG interacted electrostatically with the studied cross-linking agents to form a polyelectrolyte complex. The ex vivo study illustrated a sustained release profile of DPX with enhanced skin permeation from the film loaded PNPs. Moreover, the PNPs was able to penetrate deeper into skin layers. Therefore, DPX transdermal film developed in this work could be considered as a successful drug delivery with better patient compliance for the treatment of PE.

Abstract
Use of transdermal patches can evade many issues associated with oral drug delivery, such as first-pass hepatic metabolism, enzymatic digestion attack, drug hydrolysis and degradation in acidic media, drug fluctuations, and gastrointestinal irritation. This article reviews various transdermal patches available in the market, types, structural components, polymer role, and the required assessment tools. Although transdermal patches have medical applications for smoking cessation, pain relief, osteoporosis, contraception, motion sickness, angina pectoris, and cardiac disorders, advances in formulation development are ongoing to make transdermal patches capable of delivering more challenging drugs. Transdermal patches can be tailored and developed according to the physicochemical properties of active and inactive components, and applicability for long-term use. Therefore, a number of chemical approaches and physical techniques for transdermal patch development are under investigation.
