Abstract: The invention relates to a pharmaceutical composition comprising: at least one antiparasitic active ingredient for providing the pharmacological therapeutic effect; an agent having bio-adhesive properties that helps to reduce the motility and reproduction of the parasites, increasing the period of time for which the product remains on the skin of the animals; an agent having permeation- or absorption-promoting properties that contributes to increasing the cutaneous permeability of the active ingredient; a surfactant agent that is absorbed in an oil-water interface, and as a result, the molecules of said surfactant agent form a kind of bridge between the polar phase (water) and the non-polar phase (oil), thereby making the transition between both phases less abrupt; an oil which will form the oily phase of the emulsion, and which will incorporate the active ingredient; and a neutralizing agent.

Abstract: The present invention specifically refers to a pharmaceutical system for preparation of solid pharmaceutical forms for administering therapeutic substances improving their bioavailability; said system is particularly suitable for administering sensitive active principles by their proteinaceous nature or by being nucleic acids since polymeric excipients with good matrix and bioadhesion properties are used which together with the impermeability conferred by the applied coating make the prepared system a delivery form with excellent performance.

Abstract: The invention relates to a composition of solid lipid nanoparticles taking the form of a nano-coating for natural fresh foodstuffs, such as seeds, cereals, fruits or vegetables, preferably fresh fruits and vegetables which are coated by means of fluidization, immersion or spraying. According to the invention, the composition comprises: (a) solid lipids or wax, (b) emulsifying stabilizing agents, and film-forming materials in an aqueous dispersion or solution. The inclusion of a submicronic lipophilic system in aqueous dispersion allows the application of the composition to be easily controlled since it is a fluid system with low viscosity, which is advantageous in that it can be applied easily and uniformly and provides improved coating properties, such as sheen, mechanical strength and gas permeability inter alia.

Abstract: A process for the preparation of nanoparticles for the encapsulation of active constituents, the nanocapsules prepared being dispersible in aqueous phase in colloidal form, non-toxic, biocompatible, stable in colloidal suspension and economical. In the process, two non-oily solvents as used, together with a third, oily solvent.
