Publication number: 20240156964Abstract: The compositions and methods described herein are topically applied to the skin with negligible or no skin irritation and can direct or prevent transport through the skin. The compositions contain neat ionic liquids, optionally in combination with a drug to be delivered. In a preferred embodiment, the compositions increase transdermal transport of the drug to be delivered. In some embodiments, the compositions disrupt bacterial biofilms. This is particularly beneficial in the treatment of antibiotic resistant skin infections. In other embodiments, the compositions direct delivery within the skin. In still other embodiments, the compositions prevent transfer of substances through the stratum corneum. The disclosed compositions and methods can be tuned and modified such that they can be used to treat or prevent a variety of different diseases and disorders.Type: ApplicationFiled: September 22, 2023Publication date: May 16, 2024Inventors: Michael Zakrewsky, Samir Mitragotri, David T. Fox, Andrew Koppisch, Rico Del Sesto, Katherine Lovejoy

Publication number: 20210162050Abstract: Compositions containing a complex that contains a cation with alkyl chains and a macromolecule anion, and methods of making and using are disclosed. The compositions are typically charge neutral and a liquid at room temperature and standard pressure. The macromolecule anions may be nucleic acids, peptides, proteins, and/or carbohydrates. The compositions have enhanced penetration across the skin barrier (stratum corneum) and into the skin cells, delivering the macromolecules to the skin cells. The compositions are topically applied to the skin and are particularly useful for treatment of skin conditions.Type: ApplicationFiled: February 5, 2021Publication date: June 3, 2021Inventors: Michael Zakrewsky, Samir Mitragotri

Patent number: 10828265Abstract: Melts or ionic liquids containing amorphous propranolol, topical formulations and patches for transdermal drug delivery, and methods of making and using thereof are described herein. The melts or ionic liquids may be in a topical drug delivery formulation or patch to be applied to the skin. The drug delivery formulation or patch contains a sufficient amount of the amorphous propranolol to deliver a therapeutically effective amount of the amorphous propranolol to the patient in need of treatment, such as for the treatment or amelioration of infantile hemangioma. The formulations have a low viscosity and reduced skin irritation compared to the crystalline propranolol free base (PFB). The melts or ionic liquids can be formed by a salt metathesis reaction.Type: GrantFiled: December 11, 2017Date of Patent: November 10, 2020Assignee: The Regents of the University of CaliforniaInventors: Kazuhiro Aoyagi, Michael Zakrewsky, Samir Mitragotri

Patent number: 7236936Abstract: A medical infusion pump with a bar code reader having simplified and enhanced security features. The infusion pump with bar code reader is comprised of an infusion pump with a housing, a control display screen and control software for operating the infusion pump according to input infusion data. A bar code reader is contained in the infusion pump housing and operatively attached to communicate scanned bar code infusion data to the pump display screen and to the control software. At least one initialization button for starting execution of a bar code scanning program is operatively connected through circuitry in the pump, the program activating the bar code reader to scan for an authorized user code, for an authorized user ID code, for a patient ID code, and for infusion data compatible for operating the infusion pump. A confirmation program and confirmation buttons manually operable by the authorized user.Type: GrantFiled: December 30, 2002Date of Patent: June 26, 2007Assignee: B. Braun Medical, Inc.Inventors: Gale White, Ruth Kummerlen, Charlotte Ray, Roberta Stavely, Michael Zakrewski, Roger Hill
