[PMID: 37999348 PMCID: PMC10672809 DOI: 10.3390/membranes13110861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 10/14/2023] [Accepted: 10/24/2023] [Indexed: 11/25/2023]
Abstract
Prolonged analgesia is important to safeguard the patient's comfort and safety during and after surgery in clinical practice. To meet the demand for prolonged analgesia, medical professionals often resort to increasing drug frequency, which may lead to poor patient compliance and serious complications due to drug overdose. Therefore, it is of great interest to develop controlled-release drug delivery systems for local anesthetics, enabling slow and controlled drug release to prolong the analgesic effect and minimize systemic toxicity. In this study, we utilized an electrospinning technique to fabricate nonwoven poly(caprolactone) (PCL) fibrous membranes loaded with Ropivacaine and performed proof-of-principle experiments on both in vitro drug release tests and in vivo animal tests, to further prolong the analgesic effect of Ropivacaine and improve postoperative local pain management and chronic pain treatment. Material characterization and in vitro drug release studies confirmed the feasibility of the Ropivacaine-loaded PCL fibrous membranes for sustained release. The drug loading content and drug loading efficiency of Ropivacaine-loaded fibrous membrane are 8.7 ± 0.3 wt% and 96 ± 3 wt%, respectively. Evaluation in an animal model demonstrated prolonged anesthesia effects along with excellent biocompatibility and stability. At 72 h, the cumulative release accounted for approximately 50% of the drug loading content. This study offers novel approaches and strategies for clinical postoperative pain management and chronic pain treatment, while providing new insights and directions for the design of local anesthetic controlled-release delivery systems.

Electrospun polymer fibers modified with FK506 for the long-term treatment of acute cardiac allograft rejection in a heart transplantation model. Biomater Sci 2023; 11:4032-4042.

Abstract
FK506, a first-line immunosuppressant, is routinely administered orally and intravenously following heart transplantation. However, frequent administration can result in a substantial psychological burden to patients, resulting in non-adherence to medication. The purpose of our study is to overcome the disadvantages of systemic drug administration by developing a polymer-based delivery system that is tunable and biodegradable and that can release highly hydrophobic FK506 over extended periods to treat or prevent acute cardiac allograft rejection. Using an electrospinning method, long-acting microfibers were prepared, and FK506 appeared to be continuously released for up to 14 days based on the in vitro release profiles. After implanting the microfiber subcutaneously into the abdominals of transplanted rats, it was found that the infiltration of T cells and macrophages and the secretion of interleukin-2 (IL-2) and IL-1β were significantly reduced compared with those of the free FK506 groups. More importantly, the mean survival time (MST) of the PCL-FK506 group was significantly extended in comparison with that of untreated control recipients and free FK506 (MST of untreated control recipients, free FK506, and PCL-FK506 was 8, 26.1, and 37, respectively). In conclusion, we propose that this drug delivery approach would be suitable for developing long-lasting immunomodulatory agents that prolong cardiac graft survival safely and effectively.

[PMID: 36679132 PMCID: PMC9865042 DOI: 10.3390/polym15020251] [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: 12/06/2022] [Revised: 12/25/2022] [Accepted: 12/28/2022] [Indexed: 01/05/2023] Open
Abstract
Electrospun fibrous membranes loaded with chemotherapy drugs have been broadly studied, many of which have had promising data demonstrating therapeutic effects on cancer cell inhibition, tumor size reduction, the life extension of tumor-bearing animals, and more. Nevertheless, their drug release profiles are difficult to predict since their degradation pattern varies with crystalline polymers. In addition, there is room for improving their release performances, optimizing the release patterns, and achieving better therapeutic outcomes. In this review, the key factors affecting electrospun membrane drug release profiles have been systematically reviewed. Case studies of the release profiles of typical chemotherapy drugs are carried out to determine the preferred polymer choices and techniques to achieve the expected prolonged or enhanced release profiles. The therapeutic effects of these electrospun, chemo-drug-loaded membranes are also discussed. This review aims to assist in the design of future drug-loaded electrospun materials to achieve preferred release profiles with enhanced therapeutic efficacies.

Int J Pharm 2022; 611:121354. [PMID: 34883208 DOI: 10.1016/j.ijpharm.2021.121354] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 11/30/2021] [Accepted: 12/02/2021] [Indexed: 12/14/2022]
Abstract
Topically applied antiviral creams and patches are the commercially available options for the treatment of herpes labialis. The nanofibrous patches could be a new direction in the formulation. The project aimed to formulate core-shell type nanofibrous scaffolds loaded with dexpanthenol (shell) and acyclovir (core). To achieve the fast dissolution of the antiviral agent, hydroxypropyl-beta-cyclodextrin was used as a complexation agent. The further aim was to study the prepared electrospun scaffolds' morphological- and physicochemical properties and antiviral activity. The fibrous samples were prepared by electrospinning using polyvinylpyrrolidone (PVP) as a shell, hypromellose (HPMC), and poly(ethylene oxide)(PEO) composite or poly(vinyl alcohol) (PVA) as a core polymer. The morphology of the prepared sample was studied by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Raman spectroscopy. The SEM photos showed that fibrous structures were obtained. In the case of the PVA/PVP composition, the desired structure was obtained. While when HPMC-PEO was used as a core, the core-shell structure could not be observed. The Raman measurements revealed the mixed fibre structure of this sample. All of the fibrous samples released about 100% of acyclovir and also the dexpanthenol within 20 min. Coaxially electrospun fibres of different compositions were successfully prepared with various structural homogeneities, furthermore, a better antiviral activity could be achieved compared to the commercially available Zovirax cream.
