摘要:
A nanodispersion comprises (a) a membrane-forming molecule, (b) a coemulsifier and (c) a lipophilic component, in pharmaceutical end formulations, the nanodispersion being obtainable by (α) mixing the components (a), (b) and (c) until a homogeneous clear liquid is obtained, and (β) adding the liquid obtained in step (α) to the water phase of the pharmaceutical end formulations, where steps (α) and (β) may be carried out without high energy mixing or homogenization. The nanodispersions prepared according to this invention are suitable as transport vehicles for pharmaceutical active agents.

The invention relates to preparations for the improved release of oxygen into the skin and to the use of same as cosmetics/dermatics. The preparations according to this invention contain, as the essential component, fluorocarbon emulsions consisting of nonionic emulsifiers and an oxygen-loaded fluorocarbon or fluorocarbon mixture, the fluorocarbon content being in the range from 0.05 to 100% by weight/volume. They are prepared by emulsifying the corresponding components and incorporating the resulting emulsion in known carriers for, for example, ointments, creams, lotions, waters, alcoholic extracts, pastes, powders, gels, tinctures or masks.

The invention relates to pharmaceutical compositions which are incorporated into the skin with the aid of novel microaggregates as carriers. The object of the invention is to make available pharmacological active compounds in a biologically and chemically inert carrier for therapeutic and diagnostic administration to the skin or for systemic administration, and in this way to make deeper penetration into the skin or transdermal transport possible. According to the invention, this is effected by means of a pharmaceutical composition for topical administration, which contains asymmetric lamellar aggregates, consisting of phospholipids, pharmacological active compounds and fluorocarbons or fluorocarbon mixtures, the proportion of fluorocarbon being in the range from 1 to 100% weight/volume, in a pharmaceutical excipient which is suitable for topical administration. Preparation is effected by emulsification of the appropriate constituents and use in ointments, creams, lotions, pastes, gels, powders or on a dressing or plaster or by means of a spray.

The invention relates to a preparation for topical use, having light protection properties and in a special application form. In the known light protection agents containing the naturally occurring active compound melanin, the problem is inadequate transport of the melanin to its site of action. According to the invention, this problem is solved by a preparation for topical use which is characterised in that it contains melanin, dissolved or dispersed in one or more fluorocarbons, which are present as asymmetric lamellar phospholipid aggregates in an aqueous system together with a phospholipid, with a particle size of the aggregates in the range from 200 to 3000 nm.

The invention relates to a dermatological agent for assisting the transport of oxygen in the skin, a process for its preparation and the use thereof. The problem with the known dermatological agents is the inadequate supply of oxygen to the skin and the adjoining tissue. The object of the invention is therefore to get through the horny layer of the skin and the epidermis by penetration processes in order to increase the oxygen concentration in the dermal area and adjoining tissue and to activate metabolic processes. According to the invention, this is effected by means of a dermatological agent containing asymmetric lamellar aggregates, consisting of phospholipids and oxygen-laden fluorocarbon or fluorocarbon mixture, the amount of fluorocarbon being in the range from 0.2 to 100% weight/volume, in a carrier which is suitable for dermatological use. Preparation is effected by emulsification of the corresponding constituents, and use in ointments, creams, lotions, waters, alcoholic extracts, pastes, powders, gels, tinctures or on dressings and plasters or in a spray.
摘要:
The present invention relates to a use of 1,2-decanediol for reduction of the sebum concentration of the skin, a cosmetic and/or dermatological formulation for topical application comprising 1,2-decanediol, a method for reduction of the sebum concentration of the skin and a use of 1,2-decanediol and a method for assisting the penetration of one, two, three, four or more active compounds into areas of the skin with increased sebum production.
摘要:
An alcoholic, aqueous gel-like phospholipid composition is disclosed which contains, as alcohols, ethanol, 1-propanol or 2-propanol, which is characterized in that this composition is a liposomal gel composed of 15.00 to 30.00 parts by weight of a phospholipid concentrate, 14.00 to 20.00 parts by weight of alcohol and 50 to 71.00 parts by weight of an aqueous solution as the remainder. The use of this phospholipid composition for the preparation of liposomal solutions by dilution with a solution and topical preparations which contain these solutions are additionally disclosed.
