The present invention aims to provide a method for producing a microneedle device comprising a coating comprising dexmedetomidine and isoproterenol, in which the stability of isoproterenol during production and after production of the microneedle device is high. A method for producing a microneedle device according to one embodiment of the present invention comprises coating microneedles with a coating liquid to form a coating on the microneedles. The microneedle device comprises a substrate, microneedles disposed on the substrate, and a coating formed on the microneedles. The coating liquid comprises dexmedetomidine or a pharmaceutically acceptable salt thereof, isoproterenol or a pharmaceutically acceptable salt thereof, ethylenediaminetetraacetic acid or a pharmaceutically acceptable salt thereof, and a sulfated polysaccharide.

The present invention relates to the field of cancer therapy. In particular, the present invention relates to a method of preventing, treating or inhibiting the development of tumours and/or metastases in a subject by administering one or more immunomodulators into the skin via a microneedle device.

Provided are a composition for treating or preventing recurrence of keloid comprising tauroursodeoxycholic acid as an active ingredient, and a method for treating keloid or preventing recurrence of keloid using the composition.

An application device for a fluid delivery includes a housing having a bore extending from a bottom of the housing. The bore is sized and shaped for receiving at least a portion of the fluid delivery apparatus. The application device also includes an impact component for impacting the fluid delivery apparatus and moving at least a portion of the fluid delivery apparatus towards a user's skin. The application device includes a safety arm that is positionable relative to the impact component between a locked configuration in which the impact component is secured in a safety position, and a released configuration in which the impact component is free to move within the housing for impacting the fluid delivery apparatus.

The present invention relates to a skin administration system capable of improving the efficiency of skin delivery of an ingredient for controlling release of neurotransmitters and, particularly, to a microneedle containing an ingredient for controlling release of neurotransmitters.

A cold atmospheric plasma (CAP)-mediated ICB therapy/delivery device are disclosed herein that employs a patch having microneedles that are used to deliver the CAP transdermally along with an immune checkpoint inhibitor for enhancing transdermal treatment efficacy. The hollow-structured microneedle patch can facilitate the transportation of CAP through the skin, causing tumor cell death. The release of cancer antigens then promotes the maturation of dendritic cells in the tumor-draining lymph nodes, subsequently initiating the T cell-mediated immune response. Anti-PDL1 antibody (aPDL1), an immune checkpoint inhibitor (or other immune checkpoint inhibitors), released from the microneedle patch (in some embodiments) further augments the anti-tumor immunity. The transdermal combinational CAP and ICB therapy inhibits tumor growth for both primary tumors as well as distant tumors, with prolonged survival in the tumor-bearing mice. Such results should translate to other species.

Embodiments of the disclosure are related to a method of treating cancer including preventative treatment comprising administering nitrous oxide and oxygen to the patient by inhalation, and/or administering a botulinum toxin to the patient by injection, wherein the latter is directed to preventative treatment.

Disclosed herein are cohesive soft tissue fillers, for example, dermal and subdermal fillers, based on hyaluronic acids and pharmaceutically acceptable salts thereof. In one aspect, hyaluronic acid-based compositions described herein include a therapeutically effective amount of at least one anesthetic agent, for example, lidocaine. The present hyaluronic acid-based compositions including lidocaine have an enhanced stability and cohesivity, relative to conventional compositions including lidocaine, for example when subjected to sterilization techniques or when stored for long periods of time. Methods and processes of preparing such hyaluronic acid-based compositions are also provided.

The present invention provides for microneedle arrays and related systems and methods. Particularly, microneedle arrays that are configured to deliver active agents, including nucleic acids and vaccines, are provided. Additional related methods of vaccinating and minimizing the amount of vaccine necessary for effective inoculation are also provided.

A method of forming an implant in the tissue can include: providing an injectable composition having a neat liquid carrier, wherein the neat liquid carrier is substantially liquid at room temperature and/or about body temperature; and injecting the neat liquid solution into the tissue at the rate of 10-12000 injections per minute and/or at an amount of 1.0E-02 ml to 1.0E-16 ml per needle per injection. The neat liquid carrier can be polymeric or non-polymeric. The neat liquid carrier can be biodegradable. The neat liquid carrier can include a viscosity-modifying agent. The injecting can form an implant with area greater than or equal to 5 mm.sup.2. The neat liquid carrier can be injected at a depth of 10 microns to 5 mm. The neat liquid solution can include a drug or other agent.
