Ruan J, Liao S, Tang J, Fang L. Evaluation of Dose-Response Relationship of Permeation Enhancer Isopropyl Myristate Release on Drug Release: Release Enhancement Efficiency and Molecular Mechanism. AAPS PharmSciTech 2023; 25:1. [PMID: 38114839 DOI: 10.1208/s12249-023-02713-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 11/19/2023] [Indexed: 12/21/2023] Open
Abstract
The objective of this study is to investigate the dose-response relationship between various concentrations of permeation enhancers (PEs) and their ability to enhance drug release from a polymer matrix, utilizing an innovative parameter known as release enhancement efficiency (K). Additionally, the molecular mechanism underlying dynamic enhancement was also examined. Isopropyl myristate (IPM) was used as model enhancer and zolmitriptan (ZOL) was used as model drug to investigate dose-effect relationship in pressure sensitive adhesives (PSA). The release behavior of the PEs was determined by LC-MS/MS and verified by confocal laser scanning microscopy (CLSM). The enhancing effect of the PE on ZOL release was evaluated through in vitro release experiments and further validated by pharmacokinetics study. And the molecular mechanism was characterized with thermal analysis (DSC), Fourier transform infrared spectroscopy (FT-IR) and molecular dynamics simulation. K was 0.156, 0.286 and 0.279 at 3%, 6% and 9% IPM concentrations, indicating that the enhancement efficiency reached the maximum when the 6% IPM was applied. According to the mechanism research results, the fluidity of PSA increased linearly with the increase of IPM concentrations, but the interaction between IPM and ZOL reached its strongest point at 6%. In summary, the increase of K value (from 0 to 6% IPM content) was caused by the synergy of increased mobility of PSA and interaction (dipole-dipole and hydrogen-bond) among three components, and when the above two actions were in antagonistic, K no longer increased (6-9% IPM content).

[PMID: 37667787 PMCID: PMC10475288 DOI: 10.2147/dddt.s417051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 08/01/2023] [Indexed: 09/06/2023] Open
Abstract
From a clinical perspective, local anesthetics have rather widespread application in regional blockade for surgery, postoperative analgesia, acute/chronic pain control, and even cancer treatments. However, a number of disadvantages are associated with traditional local anesthetic agents as well as routine drug delivery administration ways, such as neurotoxicity, short half-time, and non-sustained release, thereby limiting their application in clinical practice. Successful characterization of drug delivery systems (DDSs) for individual local anesthetic agents can support to achieve more efficient drug release and prolonged duration of action with reduced systemic toxicity. Different types of DDSs involving various carriers have been examined, including micromaterials, nanomaterials, and cyclodextrin. Among them, nanotechnology-based delivery approaches have significantly developed in the last decade due to the low systemic toxicity and the greater efficacy of non-conventional local anesthetics. Multiple nanosized materials, including polymeric, lipid (solid lipid nanoparticles, nanostructured lipid carriers, and nanoemulsions), metallic, inorganic non-metallic, and hybrid nanoparticles, offer a safe, localized, and long-acting solution for pain management and tumor therapy. This review provides a brief synopsis of different nano-based DDSs for local anesthetics with variable sizes and structural morphology, such as nanocapsules and nanospheres. Recent original research utilizing nanotechnology-based delivery systems is particularly discussed, and the progress and strengths of these DDSs are highlighted. A specific focus of this review is the comparison of various nano-based DDSs for local anesthetics, which can offer additional indications for their further improvement. All in all, nano-based DDSs with unique advantages provide a novel direction for the development of safer and more effective local anesthetic formulations.

Abstract
Dissolvable microneedle array patches offer the possibility to deliver active pharmaceutical ingredients bypassing the gastrointestinal tract by piercing the stratum corneum. Usually, microneedles are produced by micromolding but this often results in a waste of active pharmaceutical ingredient. In this study, inkjet printing was investigated as a manufacturing technology for dissolvable microneedle array patches. A suitable ink for the printing process was developed for lisinopril as a peptidomimetic model drug. The printing process was optimized. Povidone was found to be a promising polymer for the precise and smooth production of dissolvable microneedles. Different patterns of microneedles and blank spaces were successfully printed into one microneedle array patch. It was possible to exactly define the cavities to be filled. The amount of lisinopril was precisely adjusted between 95.14 and 99.26 % of the target dose. The applied method demonstrated the precise dosage opportunities of the inkjet printing methodology for customization and drug waste reduction. Inkjet printing could be used as a precise manufacturing method for personalized microneedle array patches as well as to combine incompatible drug substances in a single patch.

Abstract
Silymarin constituents are extensively investigated in the treatment of skin disorders. The main constituents of silymarin include taxifolin (TX), silychristin (ST), silydianin (SDN), silybin A (SA), silybin B (SB), isosilybin A (ISA) and isosilybin B (ISB). The objective of the present study was to determine in-vitro dermal kinetics of individual silymarin constituents in human skin models and to develop a silymarin topical formulation. In-vitro studies indicate human skin binding of silymarin was in the range of 2.09 to 12.3% and half-life of silymarin constituents was > 15.5 h in epidermal and dermal cells. Topical silymarin cream was prepared using sulfobutylether-β-cyclodextrins as solubilizer and propylene glycol as permeation enhancer. The cream was subjected to ex-vivo human skin permeation studies. In ex-vivo studies, cumulative amount of TX, ST, SDN, SA, SB, ISA and ISB permeated across human cadaver skin at 24 h was 921 ± 13.5, 1992 ± 67.6, 345 ± 39.2, 1089 ± 45.0, 1770 ± 100, 1469 ± 81.5 and 1285 ± 33.1 ng/cm2, respectively. The amount TX, ST, SDN, SA, SB, ISA and ISB retained after 24 h was 60.7 ± 8.2, 376 ± 45.5, 72.3 ± 6.9, 66.4 ± 8.0, 208 ± 31.3, 154 ± 12.4 and 102 ± 6.3 ng/mg of human cadaver skin, respectively. The study results demonstrate silymarin topical formulation could deliver significant amount of silymarin constituents into skin. The developed silymarin formulation could be beneficial for treatment or management of a broad spectrum of dermatological disorders.

Abstract
Background Gestodene (GEST) is widely used in female contraception. It is currently being used as an oral contraceptive. However, unfortunately, oral contraceptives are often associated with several bothersome side effects and poor compliance. Therefore, a sustained delivery system for GEST to overcome these shortcomings is highly desirable. Objectives The present study successfully developed a kind of novel dissolving microneedles (DMNs) with a potential for sustained release and a minimally invasive intradermal treatment of GEST. Methods The dissolving microneedles containing GEST were fabricated using polyvinylpyrrolidone as the base material. The characteristics in vitro and pharmacokinetics in vivo of GEST-loaded DMNs were investigated. Results The results showed that the microneedle could pierce the porcine skin and release the drug at an average dose of 20µg/cm2 daily for seven days. The pharmacokinetic experiment of the microneedles indicated that the plasma level of GEST in rats increased with increasing drug dosage, and the plasma drug concentration-time curves were much flatter compared with subcutaneous injection and oral administration. In addition, no cutaneous irritation was observed. Conclusions GEST-loaded DMNs may be a promising intradermal sustained delivery system for contraceptive use.

Abstract
Microneedles are used to deliver drugs topically across the skin and mucous membranes. Dissolvable microneedles are made using soluble polymers, which disintegrates in the tissue and release the entire payload instantaneously including the polymer construct. Often, a slow release of drug into the tissue is desirable to overcome the severity of side effects at the site of administration as well as systemic adverse effects. In addition, controlled release of active pharmaceutical ingredient (API) only (not the excipients) is safe and effective particularly when the drug delivery is intended to sensitive organs like the eye. In this project, the feasibility of fabricating polymer coated polymeric (PCP) microneedles to achieve a gradual release of only the active ingredient from the device was investigated. The potential application of such PCP microneedles in the dermal and intravitreal drug delivery was also explored using animal tissue models. The PCP microneedles were found to be intact even after prolonged contact with the release medium. The time at which 50% (T50%) of dextran (10 K) was released in case of microneedles prepared using 20% of core polymer (PVP-K30) was about 15 min versus less than 5 min in the case of uncoated microneedles. Whereas when the core polymer concentration was increased to 50%, the T50% was increased to 90 min. The rate of release depended on the polymer molecular weight grade. The rate of drug release was not influenced by the total amount of concentration of dextran. The PCP microneedles of lidocaine hydrochloride could constantly release the drug for up to 9 h in the skin tissue. Likewise, the PCP microneedles infused voriconazole, intravitreally for 6 h.

Abstract
Fentanyl is a fully synthetic opioid with analgesic and anesthetic properties. It has become a primary driver of the deadliest opioid crisis in the United States and elsewhere, consequently imposing devastating social, economic, and health burdens worldwide. However, the neural mechanisms that underlie the behavioral effects of fentanyl and its analogs are largely unknown, and approaches to prevent fentanyl abuse and fentanyl-related overdose deaths are scarce. This review presents the abuse potential and unique pharmacology of fentanyl and elucidates its potential mechanisms of action, including neural circuit dysfunction and neuroinflammation. We discuss recent progress in the development of pharmacological interventions, anti-fentanyl vaccines, anti-fentanyl/heroin conjugate vaccines, and monoclonal antibodies to attenuate fentanyl-seeking and prevent fentanyl-induced respiratory depression. However, translational studies and clinical trials are still lacking. Considering the present opioid crisis, the development of effective pharmacological and immunological strategies to prevent fentanyl abuse and overdose are urgently needed.

Abstract
The polymer coated polymeric (PCP) microneedles were fabricated using PVP K30 in the core and ethyl cellulose in the coating. The PCP microneedles do not disintegrate in the tissue upon insertion and rather stays intact and allows diffusion of drugs and analytes across the membrane both inward and outward. In this project the potential use of PCP microneedles for sampling analytes from the dermal tissue was explored. The amount of analyte sampled depended on the concentration in the tissue, physicochemical properties of the analyte and duration of insertion of the array in the tissue. Further, an advanced type of PCP microneedle array was fabricated by entrapping absorbent beads in the core microneedles. The adsorbent enabled the PCP microneedles to recover significantly higher amount of analyte from the tissue.

Abstract
Pain management is an urgent issue to solve with complex mechanisms. Localized acute pain requires rapid and accurate delivery of drugs with less distribution in the blood circulation while chronic pain requires controlled release of drugs with long drug retention time. The transdermal route, a promising way with high patient compliance was known for painless delivery, long drug retention time, stable blood concentration, easily controlled dosage and release rate as well as the fewer side effects. This review presents transdermal route for pain management according to the different sites of action which drugs aim to reach, and illustrates different analgesic mechanisms, dosage forms, transdermal enhancements and clinical applications. In addition, the review concludes the difference of pain types and presents the future aims of pain management, thereby providing a reference for researches focusing on percutaneous analgesia.

Abstract
Transdermal drug delivery (TDD) has recently emerged as an effective alternative to oral and injection administration because of its less invasiveness, low rejection rate, and excellent ease of administration. TDD has made an important contribution to medical practice such as diabetes, hemorrhoids, arthritis, migraine, and schizophrenia treatment, but has yet to fully achieve its potential in the treatment of obesity. Obesity has reached epidemic proportions globally and posed a significant threat to human health. Various approaches, including oral and injection administration have widely been used in clinical setting for obesity treatment. However, these traditional options remain ineffective and inconvenient, and carry risks of adverse effects. Therefore, alternative and advanced drug delivery strategies with higher efficacy and less toxicity such as TDD are urgently required for obesity treatment. This review summarizes current TDD technology, and the main anti-obesity drug delivery system. This review also provides insights into various anti-obesity drugs under study with a focus on the recent developments of TDD system for enhanced anti-obesity drug delivery. Although most of presented studies stay in animal stage, the application of TDD in anti-obesity drugs would have a significant impact on bringing safe and effective therapies to obese patients in the future.

Abstract
INTRODUCTION A microneedle array patch (MAP) has been studied as a means for delivering drugs or vaccines and has shown superior delivery efficiency compared to the conventional transdermal drug delivery system (TDD). This paper reviews recent advancements in the development of MAPs, with a focus on their size, shapes, and materials in preclinical and clinical studies for pharmaceutics. AREA COVERED We classified MAPs for drug delivery into four types: coated, dissolving, separable, and swellable. We covered their recent developments in materials and geometry in preclinical and clinical studies. EXPERT OPINION The design of MAPs needs to be determined based on what properties would be effective for the target diseases and purposes. In addition, in preclinical studies, it is necessary to consider not only the novelty of the formulations but also the feasibility of clinical application. Currently, clinical studies of microneedles loaded with various drugs and vaccines are in progress. When the regulation of pharmaceutical microneedles is established and more clinical studies are published, more drugs will be developed as microneedle products and clinical research will proceed. With these considerations, the microneedle array patch will be a better option for drug delivery.

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
Microneedles are being widely explored for dermal delivery of macromolecules. They have the capability and the potential for entrapping enzymes such as lysozyme within a polymeric matrix that do not alter the protein integrity, enable a bolus or a sustained release. In this study, polymeric microneedles have been used to entrap lysozyme (14 kDa) using biodegradable and dissolving polymers such as Polyvinylpyrrolidone (PVP), Hyaluronic acid (HA), and Poly lactic co glycolic acid (PLGA). Microneedles were fabricated using mold casting technique. The structural strength was determined using texture analyzer where PLGA microneedles (16.56 ± 0.23 g) required a significantly higher puncture force as compared to PVP and HA microneedles (12.10 ± 0.04 g and 11.40 ± 0.32 g respectively). The release profile showed an instantaneous release in the case of PVP and HA with almost 50% of the drug released within the first 20 min in both cases and remaining drug was released within the next 2 h whereas Lysozyme entrapped in PLGA showed a release of 29.53 ± 0.78% of lysozyme 72 h. Lysozyme entrapped in microneedles was characterized using circular dichroism and SDS-page analysis for structural stability post microneedle fabrication. The stability studies were performed on these polymeric microneedles for understanding its delivery potential of bio-active lysozyme. At the end of 90 days lysozyme concentration entrapped was 90.35 ± 0.06% 93.76 ± 0.34% 91.74 ± 0.37% for PVP, HA and PLGA respectively. The protein integrity remained intact for three months (α + β) sheets remained intact in the three different polymeric microneedles. The enzyme assay showed that the enzyme entrapped inside microneedles is biologically active and could be used to lyse bacterial infections for dermal applications. However, a detailed analysis of protein formulations would be useful for extending microneedles applications in wounds, skin infections.

Colloidal lipid nanodispersion enriched hydrogel of antifungal agent for management of fungal infections: Comparative in-vitro, ex-vivo and in-vivo evaluation for oral and topical application. Chem Phys Lipids 2020; 233:104981. [PMID: 33031802 DOI: 10.1016/j.chemphyslip.2020.104981] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Revised: 09/21/2020] [Accepted: 09/28/2020] [Indexed: 11/25/2022]
Abstract
Ketoconazole (KZ) is broad spectrum antifungal drug, used for the treatment of fungal infections. KZ's clinical topical use has been associated with some adverse effects in healthy adults particularly local reactions, such as stinging, severe irritation, and pruritus. However, bioavailability of KZ after oral administration is low from tablets due to its low aqueous solubility. The objective of this investigation was development and characterization of KZ-containing solid lipid nanoparticles (KZ-SLNs) and SLN-containing hydrogel (KZ-SLN-H) for oral and topical delivery of KZ. KZ-SLNs were prepared using homogenization-sonication method. Optimal KZ-SLN formulation was selected based on physicochemical and in-vitro release studies. Optimized KZ-SLN converted to KZ-SLN hydrogel (KZ-SLN-H) using gelling polymers and optimized with rheological and in-vitro studies. Further, optimized KZ-SLN and KZ-SLN-H formulations evaluated for crystallinity, morphology, stability, ex-vivo and in-vivo pharmacokinetic (PK) studies in rats, comparison with KZ suspension (KZ-S) and KZ-S hydrogel (KZ-SH). Optimized KZ-SLN formulation showed desirable characters. KZ-SLN and KZ-SLN-H formulations exhibited spherical shape, converted to amorphous, sustained release behaviour and enhanced permeability (p < 0.05). Moreover, both formulations were stable for three months at 4 °C and 25 °C. PK studies revealed 1.9 and 1.5-folds, 3.5 and 2.8-folds enhancement of bioavailability of optimized KZ-SLN and KZ-SLN-H formulations (p < 0.05) compared with KZ-S and KZ-SH formulations, respectively. Overall, SLN and SLN-H formulations could be considered as an efficient delivery vehicles for KZ through oral and topical administration for better control over topical and systemic fungal infections.

Abstract
The use of hot-melt extrusion (HME) technique in the preparation of semi-solid products offers several advantages over conventional processes. However, the optimization of the technique for preparation of semi-solid pharmaceuticals is challenging due to involvement of ingredients with different physical properties. Hence, a simple tool to optimize the mixing of ingredients that results in a target ratio and drug content uniformity is utmost important. In this study, a handheld colorimeter has been explored to optimize the process variables of twin screw processor for preparation of hydrophilic PEG-based ointment. The process parameters which were optimized with use of handheld colorimeter have been used for preparation of polyethylene glycol-based metronidazole ointment. The metronidazole ointment prepared by twin screw processor was compared with commercially available metronidazole gel for in vitro release testing and ex vivo permeation. The flux, ex vivo bioavailability, and Tmax of polyethylene glycol-based metronidazole ointment was found to be similar to that of marketed metronidazole gel.

Pharmaceutics 2020; 12:pharmaceutics12050448. [PMID: 32414195 PMCID: PMC7284436 DOI: 10.3390/pharmaceutics12050448] [Citation(s) in RCA: 44] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 05/07/2020] [Accepted: 05/12/2020] [Indexed: 11/16/2022] Open
Abstract
Parkinson’s disease (rp) is a progressive neurodegenerative disorder. Ropinirole (RP) is a newer generation dopamine agonist used for the treatment of PD. It is prescribed as oral dosage form. However, limited oral bioavailability and frequent dosing limits the RP usage. The objective of the current investigation was to develop, optimize, evaluate pharmacokinetic (PK) and pharmacodynamic (PCD) activity of RP loaded solid lipid nanoparticles (RP-SLNs) and nanostructured lipid carriers (RP-NLCs) and containing hydrogel (RP-SLN-C and RP-NLC-C) formulations for improved oral and topical delivery. RP loaded lipid nanoparticles were optimized and converted to hydrogel using carbopol 934 as the gelling polymer. PK and PCD studies in haloperidol-induced PD were conducted in male Wistar rats. In vitro and ex vivo permeation studies showed sustained release profile and enhanced permeation compared with control formulations. Differential scanning calorimeter and X-ray diffraction studies revealed amorphous transformation; scanning electron microscope showed the spherical shape of RP in lipid nanoparticles. PK studies showed 2.1 and 2.7-folds enhancement from RP-SLN and RP-NLC from oral administration, 3.0 and 3.3-folds enhancement from RP-SLN-C and RP-NLC-C topical administration, compared with control formulations, respectively. RP-SLN-C and RP-NLC-C showed 1.4 and 1.2-folds topical bioavailability enhancement compared with RP-SLN and RP-NLC oral administration, respectively. PCD studies showed enhanced dopamine, glutathione, catalase levels and reduced lipid peroxidation levels, compared with the haloperidol-induced PD model. Overall, the results demonstrated that lipid nanoparticles and corresponding hydrogel formulations can be considered as an alternative delivery approach for the improved oral and topical delivery of RP for the effective treatment of PD.
