  • Polymeric adhesive matrix with salified carboxylic groups for transdermal use
    Patent number: 10328034
    Abstract: Polymeric matrices for the controlled release of medicaments for the topical transdermal use comprising copolymers of acrylic and/or methacrylic acid or esters thereof having a Tg lower than 0° C., whose free carboxy groups are salified with compatible organic or inorganic bases. The matrices of the invention allow to prepare therapeutical systems for the controlled-release of active principles through the transdermal route, thus solving stability, solubility and/or bioavailability problems of the active ingredient within the matrix.
    Type: Grant
    Filed: January 25, 2017
    Date of Patent: June 25, 2019
    Assignee: BOUTY S.P.A.
