Abstract: The present disclosure describes a method for the continuous dissolution of e.g. crystalline astaxanthin or canthaxanthin suspension in oil, by applying heat for a predetermined period using an in-line or optionally batch wise-process, followed by cooling the heated solution with an oil phase or heat exchanger. The resulting oil solution may be used as such or added directly to feed components which are turned into feed compositions by extrusion, compaction or granulation. Alternatively the oil solution is spray coated or directly loaded to extruded or compacted pellets and granulates. The disclosure avoids using formulated carotenoids prepared by known multi-step production methods requiring solvents, solvent removal, cooling and emulsification with an aqueous phase or precipitation and recovery steps.

Abstract: The invention describes a method of preparing lipid compositions by associating pH sensitive compounds which maybe weak acids, bases or amphoteric compounds with at least one ionisable or pH sensitive group and low water solubility into preformed and standardised lipid particles by pH manipulation. Drug association is carried out in situ by changing the pH of the aqueous medium to pH 6-8 wherein the compound spontaneously partitions into the lipid particles. Drug association may also be carried out by exploiting pH changes in the GI tract. The lipophilic compound is solubilised by the lipid particles and may be used as such for in-vitro and pharmacokinetic assessments or processed for oral, parenteral or topical therapy.

Abstract: Compositions for forming molecular associates with lipophilic compounds and an improved method of loading lipophilic biologically active compounds into previously formed, aqueous suspensions of lipid particles. A preferred embodiment for injection purposes comprise lipid particles having sizes below 1000 nm in diameter, in a vial or other suitable container are described. The method involves mixing a lipophilic compound either in solution or as an amorphous, preferably lyophilised powder in a first container with an aqueous suspension of lipid particles contained in a second container to form molecular associates. Only minimum agitation is required. The entire procedure may be carried out instantly in situ, in sealed sterile units just prior to use in the hospital ward or by the bedside.

Abstract: A substantially homogeneous composition for human administration comprises a biologically active lipophilic compound dissolved in or associated with at least one micelle-forming lipid. For example, cyclosporin A is dissolved or dispersed in the mixture of PC and MAPC. The composition may be made by dissolving the lipid material in ethanol, adding the lipophilic compound to the ethanol and removing the ethanol, after which the composition may be formulated for human oral administration.

Abstract: Compositions that are sprayable or that are in the form of discrete particles and that contain a lipid and a biologically active compound in the form of a micronized powder combine a high initial entrapment of the active compound in the membrane lipid with sustained release at the site of application as indicated by in-vitro and in-vivo tests. In a first form pro-liposomes are prepared by spraying under pressure through a nozzle a single composition comprising at least one volatile liquid propellant, at least one membrane lipid that is at least partly dissolved or dispersed in the propellant and at least one biologically active compound that is present in dispersion in the propellant and/or the lipid, the composition being free from other solvent for the lipid. In a second form the membrane lipid and the biologically active compound are minor components of micronized solid particles whose major component is a physiologically acceptable solid carrier.

Abstract: Pro-liposome compositions comprise membrane lipids such as lecithin or distearyl dimethylammonium chloride, water-miscible solvents such as ethanol, optionally a minor proportion of water, and optionally fatty acid esters and drugs. On addition to excess water they spontaneously form dispersions of liposomes having high void volumes and high drug entrapment ratios.Aerosol compositions are presented in a volatile liquid propellant. On being sprayed they form an aerosol of droplets which, on contact with aqueous media, spontaneously form liposome dispersions.
