Abstract:
The invention relates to solid particulate film coating agents consisting of: a) 40 - 90 % by weight, preferably 40 - 70 % by weight polyvinyl alcohol-polyether graft copolymers (component A), b) up to 60 % by weight, preferably between 20 and 45 % by weight of a coloured or achromatic colouring agent (component B), c) between 0 and 30 % by weight additional conventional auxiliary agents (component C). According to the invention, the quantities of components A to C total 100 % by weight. Said coating agents are obtained by the extrusion of a plastic mass of components A) to C) and by a subsequent shaping process.
Abstract:
The invention relates to dosage forms which contain preparations of poorly water-soluble substances in a polymer matrix of polyether copolymers, said polyether copolymers being obtained by the radically initiated polymerization of a mixture from 30 to 80% by weight of N-vinyl lactam, 10 to 50% by weight of vinyl acetate and 10 to 50% by weight of a polyether, and at least one poorly water-soluble polymer, the poorly water-soluble substance being present in the polymer matrix as an amorphous substance.
Abstract:
A coating material, containing a mixture of i) a polymer obtained by radical polymerization from a) N,N-diethylaminoethyl methacrylate, and b) at least one radically polymerizable compound, selected from esters of a,ß- ethylenically unsaturated mono- and dicarboxylic acids with C1-C18 alkanols, as component A, ii) one or more antioxidants as component B, iii) one or more plasticizers as component C, and iv) other excipients as components D, wherein the total amount of the mixture of components A-D is 100 wt.%.
Abstract:
The invention relates to orally disintegrating dosage forms of taste-masked active ingredients, which are provided with a coating of polymers containing N,N-diethylaminoethylmethacrylate (DEAEMA) that is polymerized therein for masking the taste, and in which the taste-masked active ingredients are embedded in an orally disintegrating matrix.
Abstract:
Rapidly disintegrating, solid coated dosage form comprising a solid core consisting of at least 60% by weight of an auxiliary mixture, up to 40% by weight of at least one active ingredient, and optionally further auxiliaries, coated with at least one film coating comprising completely or partially hydrolyzed, rapidly water-soluble polyether-vinyl ester graft polymers, methods for the production thereof, and their use.
Abstract:
The invention relates to a method for producing preparations of substances poorly soluble in water, wherein the poorly soluble substances are present amorphously embedded in a copolymer, and the copolymer is obtained by radically initiated polymerization of a mixture of i) 30 to 80 wt% N-vinyl lactam, ii) 10 to 50 wt% vinyl acetate, and iii) 10 to 50 wt% of a polyether, with the stipulation that the sum of the components i), ii), and iii) is equal to 100 wt%, wherein the embedding of the poorly soluble substance into the copolymer occurs at temperatures above the melting point of the poorly soluble substances.
Abstract:
The invention relates to a method for production of solid solutions of poorly soluble pesticides, power products obtained by such a method and the use thereof for pesticide formulations.
Abstract:
The invention relates to preparations of active agents not easily soluble in water, consisting of carrier particles having active agent-containing coatings, wherein the active agents not easily soluble in water are embedded in coatings made of amphiphilic copolymers and the coatings are applied in the form of a solvent-free melt.
Abstract:
Use of water-soluble or water-dispersible copolymers obtained through radically-initiated polymerization of a mixture of i) 30 to 80 wt.-% of N-vinyl lactam, ii) 10 to 50 wt.-% of vinyl acetate and iii) 10 to 50 wt.-% of a polyether as a binder for the manufacture of dosing forms comprising solid active ingredients, said copolymers being conditioned in that the total of i), ii) and iii) is equal to 100 wt.-%.
