Int J Cosmet Sci 2022; 44:453-463. [PMID: 35670051 DOI: 10.1111/ics.12793] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Revised: 05/27/2022] [Accepted: 05/28/2022] [Indexed: 11/27/2022]
Abstract
OBJECTIVE Ascorbic acid (i.e., vitamin C) is an important antioxidant present in skin. The protective role of vitamin C against photoaging motivated numerous attempts to promote its topical delivery, with a success limited by its chemical instability and poor skin permeability. Vitamin C precursors, such as ascorbic acid 2-glucoside (AA2G), that are metabolized to vitamin C by enzymes present in the skin, solve the problem of stability but are limited by low skin permeability. We developed a 2% (w/v) gel formulation of AA2G application (viscosity 4.30 × 104 Pa.s, pH 5.94) and compared its passive dermal delivery with the delivery promoted by photoacoustic waves that transiently perturb the skin barrier. METHODS Photoacoustic (PA) waves were generated by laser pulses absorbed by piezophotonic (light-to-pressure) transducers. Pig skin samples were exposed to the 2% AA2G formulation alone or combined with 5 minutes of PA waves. One hour later, AA2G was extracted from the skin and quantified by reverse-phase HPLC. AA2G transdermal fluxes using Franz cells with 760 μm thick pig skin samples were also measured. RESULTS PA waves transiently enhanced skin permeability and increased dermal delivery of AA2G. AA2G was released from the formulation nearly quantitatively (92.6 ± 6.2%) in 24 hours, showing a non-Fickian behaviour controlled by diffusion and swelling. AA2G dermal delivery with exposure for 5 minutes to PA waves was compared with passive delivery to pig skin. PA waves increased the delivery of AA2G to the skin by a factor of 15 fold with respect to passive delivery, as measured from skin extracts after 1 hour of contact of the formulation with the skin. CONCLUSION 5 minutes of exposure to PA waves is a safe and effective method to deliver large quantities of AA2G to the skin.

Drug delivery systems and materials for wound healing applications. Adv Drug Deliv Rev 2018; 127:138-166. [PMID: 29626550 PMCID: PMC6003879 DOI: 10.1016/j.addr.2018.04.008] [Citation(s) in RCA: 390] [Impact Index Per Article: 65.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2018] [Revised: 04/01/2018] [Accepted: 04/03/2018] [Indexed: 01/22/2023]
Abstract
Chronic, non-healing wounds place a significant burden on patients and healthcare systems, resulting in impaired mobility, limb amputation, or even death. Chronic wounds result from a disruption in the highly orchestrated cascade of events involved in wound closure. Significant advances in our understanding of the pathophysiology of chronic wounds have resulted in the development of drugs designed to target different aspects of the impaired processes. However, the hostility of the wound environment rich in degradative enzymes and its elevated pH, combined with differences in the time scales of different physiological processes involved in tissue regeneration require the use of effective drug delivery systems. In this review, we will first discuss the pathophysiology of chronic wounds and then the materials used for engineering drug delivery systems. Different passive and active drug delivery systems used in wound care will be reviewed. In addition, the architecture of the delivery platform and its ability to modulate drug delivery are discussed. Emerging technologies and the opportunities for engineering more effective wound care devices are also highlighted.

Abstract
Sinomenine hydrochloride-loaded dissolving microneedles (SH-DM) were fabricated by maltose and poly-lactic-co-glycolic acid using a casting method. The mechanical strength of SH-DM was investigated by an insertion test. In vivo transdermal absorption experiment was performed to evaluate the percutaneous absorption of SH-DM, sinomenine hydrochloride gel (SH-G) was used as a control. The results demonstrated that prepared SH-DM was morphologically intact with sufficient mechanical strength after inserting into aluminum foil and rat skin. The value of area under curve obtained after administration of SH-DM through transdermal in rabbits showed a significantly rise and was 1.99 times higher than that of SH-G, and the relative bioavailability value was 199.21%. These results showed that SH-DM enhanced bioavailability and permeability of SH.

Abstract
A microneedle system has been developed to deliver chemical and biological agents through the stratum corneum, which is the main barrier to drug delivery. Recently, microneedles have been fabricated from various kinds of polymers, including biocompatible polymer, biodegradable polymer, and water-soluble polymer. Polymer microneedles offer the benefits of ease of fabrication, cost-effectiveness, and mass production, as well as controlled drug release using the water solubility and degradation properties of polymer. In this review, the key features of polymer microneedles are discussed, including fabrication, materials, mechanical properties, drug delivery properties, and applications. Polymer microneedles provide a promising method for transdermal drug delivery by utilizing various physical and chemical properties of polymer.

[PMID: 22575858 DOI: 10.1016/j.addr.2012.04.005] [Citation(s) in RCA: 1002] [Impact Index Per Article: 83.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2011] [Revised: 03/15/2012] [Accepted: 04/23/2012] [Indexed: 12/18/2022]
Abstract
Microneedles were first conceptualized for drug delivery many decades ago, but only became the subject of significant research starting in the mid-1990's when microfabrication technology enabled their manufacture as (i) solid microneedles for skin pretreatment to increase skin permeability, (ii) microneedles coated with drug that dissolves off in the skin, (iii) polymer microneedles that encapsulate drug and fully dissolve in the skin and (iv) hollow microneedles for drug infusion into the skin. As shown in more than 350 papers now published in the field, microneedles have been used to deliver a broad range of different low molecular weight drugs, biotherapeutics and vaccines, including published human studies with a number of small-molecule and protein drugs and vaccines. Influenza vaccination using a hollow microneedle is in widespread clinical use and a number of solid microneedle products are sold for cosmetic purposes. In addition to applications in the skin, microneedles have also been adapted for delivery of bioactives into the eye and into cells. Successful application of microneedles depends on device function that facilitates microneedle insertion and possible infusion into skin, skin recovery after microneedle removal, and drug stability during manufacturing, storage and delivery, and on patient outcomes, including lack of pain, skin irritation and skin infection, in addition to drug efficacy and safety. Building off a strong technology base and multiple demonstrations of successful drug delivery, microneedles are poised to advance further into clinical practice to enable better pharmaceutical therapies, vaccination and other applications.
