Eur J Pharm Biopharm 2024; 202:114390. [PMID: 38950716 DOI: 10.1016/j.ejpb.2024.114390] [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: 05/07/2024] [Revised: 06/19/2024] [Accepted: 06/28/2024] [Indexed: 07/03/2024]
Abstract
The current pharmacological management of androgenetic alopecia is inconvenient and requires a discipline that patients find difficult to follow. This reduces compliance with treatment and satisfaction with results. It is important to propose treatment regimens that increase patient compliance and reduce adverse effects. This work describes transdermal delivery of minoxidil partially encapsulated in β-cyclodextrin and assisted by photoacoustic waves. Photoacoustic waves transiently increase the permeability of the skin and allow for the delivery of encapsulated minoxidil. A minoxidil gel formulation was developed and the transdermal delivery was studied in vitro in the presence and absence of photoacoustic waves. A 5-min stimulus with photoacoustic waves generated by light-to-pressure transducers increases minoxidil transdermal delivery flux by approximately 3-fold. The flux of a 1% minoxidil formulation promoted by photoacoustic waves is similar to the passive flux of a 2% minoxidil commercial formulation. Release of minoxidil from β-cyclodextrin increases dermal exposure without increasing peak systemic exposure. This promotes hair growth with fewer treatments and reduced adverse effects. In vivo studies using encapsulated minoxidil and photoacoustic waves yielded 86% hair coat recovery (vs. 29% in the control group) and no changes in the blood pressure.

Hair follicle sulfotransferase activity and effectiveness of oral minoxidil in androgenetic alopecia. J Cosmet Dermatol 2024. [PMID: 39034734 DOI: 10.1111/jocd.16473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 04/29/2024] [Accepted: 07/10/2024] [Indexed: 07/23/2024]
Abstract
BACKGROUND Androgenetic alopecia (AGA) is common. While topical minoxidil remains the only FDA-approved therapeutic for AGA, its efficacy is limited in stimulating clinically significant hair regrowth over the longer term. Oral minoxidil, which is used off-label, is a promising alternative; however, its effectiveness and underlying mechanisms warrant further investigation. AIMS To elucidate the site of action and infer the physiological mechanisms underlying therapeutic responses to oral minoxidil in patients with AGA. METHODS Forty-one patients with AGA underwent 6 months of low-dose oral minoxidil treatment. Minoxidil sulfotransferase (SULT) activity was assayed in plucked scalp hair follicles. The primary outcome was hair growth after low-dose oral minoxidil treatment for a minimum of 6 months, and the secondary outcome was SULT activity in hair follicles. RESULTS After 6 months of treatment, 26 (63.4%) patients experienced a clinical improvement in alopecia symptoms. The response rate was higher in men (19/26 [73.1%]) than in women (6/15 [40.0%]). Patients with low hair follicle SULT activity demonstrated a higher minoxidil response rate than those with high enzyme activity (85% vs. 43%, p = 0.009). CONCLUSIONS Our findings indicate that low SULT activity within the hair follicles is associated with a favorable response to oral minoxidil therapy in patients with AGA. Further elucidation of the underlying mechanisms could significantly improve personalized therapeutic approaches through improved patient selection and the rational design of adjuvant treatments.

[PMID: 38313574 PMCID: PMC10836857 DOI: 10.1159/000534526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 10/05/2023] [Indexed: 02/06/2024] Open
Abstract
Introduction Androgenetic alopecia (AGA) is the most common form of hair loss, with negative impact on patient quality of life. Oral minoxidil is used off-label for AGA treatment. We hypothesized increased public interest in oral minoxidil for hair loss treatment following the New York Times (NYT) Article on oral minoxidil: "An Old Medicine Grows New Hair for Pennies a Day, Doctors Say." The objective of this study was to quantify interest in oral minoxidil for hair loss treatment before and after the NYT article and help inform dermatologists about treatments of interest to their patients. Method We performed a cross-sectional analysis of Google Trends evaluating relative prevalence of "oral minoxidil," "minoxidil," "hair loss," and "Rogaine®" 2/2022-5/2023. t tests compared mean search volume and linear regression analysis quantified changes in public interest over time. Results Oral minoxidil and minoxidil search volumes increased from 0.86 to 3.00 and 22.43 to 32.60, respectively, before and after the NYT article (both p < 0.05). Minoxidil searches continually increased by 500,000 searches per month (p < 0.001). Conclusions There was a significant and sustained increase in Google searches for oral minoxidil after publication of the NYT article, indicating increased patient interest. Larger clinical trials are needed to provide evidence-based care to AGA patients.

[PMID: 38086191 DOI: 10.1016/j.ejmech.2023.116022] [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: 10/11/2023] [Revised: 11/19/2023] [Accepted: 11/29/2023] [Indexed: 12/30/2023]
Abstract
Androgenetic alopecia (AGA) has become a widespread problem that leads to considerable impairment of the psyche and daily life. The currently approved medications for the treatment of AGA are associated with significant adverse effects, high costs, and prolonged treatment duration. Therefore, natural products are being considered as possible complementary or alternative treatments. This review aims to enhance comprehension of the mechanisms by which natural products treat AGA. To achieve this, pertinent studies were gathered and subjected to analysis. In addition, the therapeutic mechanisms associated with these natural products were organized and summarized. These include the direct modulation of signaling pathways such as the Wnt/β-catenin pathway, the PI3K/AKT pathway, and the BMP pathway. Additionally, they exert effects on cytokine secretion, anti-inflammatory, and antioxidant capabilities, as well as apoptosis and autophagy. Furthermore, the review briefly discusses the relationship between signaling pathways and autophagy and apoptosis in the context of AGA, systematically presents the mechanisms of action of existing natural products, and analyzes the potential therapeutic targets based on the active components of these products. The aim is to provide a theoretical basis for the development of pharmaceuticals, nutraceuticals, or dietary supplements.

Front Bioeng Biotechnol 2024; 11:1331754. [PMID: 38260729 PMCID: PMC10800965 DOI: 10.3389/fbioe.2023.1331754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 12/05/2023] [Indexed: 01/24/2024] Open
Abstract
Objective: Umbilical cord-derived mesenchymal stem cell membrane-loaded minoxidil (MXD) nanoparticles (STCM-MXD-NPs) were prepared to investigate their effects on hair growth in C57BL/6J mice. Methods: STCM-MXD-NPs were obtained by freeze-thawing and differential centrifugation, and their effects on hair growth were evaluated using C57BL/6J mice. The mRNA and protein expression levels of vascular endothelial growth factor (VEGF) and insulin-like growth factor-1 (IGF-1) were detected by real-time polymerase chain reaction and enzyme-linked immunosorbent assays, respectively. Protein expression levels of marker of proliferation Ki-67 (MKI67) and β-catenin (CTNNB) in skin tissue were detected by immunohistochemistry. Results: STCM-MXD-NPs improved MXD solubility. They released the drug slowly, increasing its transdermal properties, accumulation in the skin, and content in the hair bulb tissues with a better efficacy than that of ordinary MXD. Moreover, STCM-MXD-NPs significantly upregulated the mRNA and protein levels of VEGF and IGF-1 and promoted the protein expression of MKI67 and CTNNB in mouse skin tissues, promoting mouse hair growth. Conclusion: Stem cell membrane-loaded MXD nanoparticles with slow-release properties increased MXD accumulation in the skin by improving its transdermal properties, increasing VEGF, IGF-1, MKI67, and CTNNB expression levels and promoting hair growth in C57BL/6J mice.
