Ophthalmic solutions containing arabinogalactans with a protective activity on the corneal epithelium, particularly suitable for use as artificial tears stimulating the recovery of corneal lesions and also particularly useful for contact lens users, containing from 1% to 10% by weight of arabinogalactan in an aqueous solution and possible other excipients, among which tonicity-adjusting agents, pH correctors, buffers and preservatives, except for benzalkonium chloride. The compositions according to the invention have a virtually negligible viscosity, but are sufficiently mucoadhesive to assure a considerable permanence time in the area of application. Besides being well-tolerated, the aforesaid compositions have considerable re-epithelization capacity.

An ophthalmic pharmaceutical composition containing acetylcysteine as the active ingredient having a mucolitic action, suitable for administration in eyedrops, where N-acetyl-cysteine is neutralised with base DEAE-dextrane in order to reach pH levels preferably between 6.0 and 7.5, and having a physiologically acceptable osmolarity less than 320 mOsm/kg. The presence of a neutralising agent for N-acetyl-cysteine that does not negatively affect the composition osmolarity allows the formulation to be isotonic or even hypotonic, thus avoiding the irritative and potentially damaging effects of previous ophthalmic products containing N-acetyl-cysteine.

In the treatment of ophthalmologic pathologies in general and in particular in the treatment and prevention of side-effects on eye following photorefractive therapy (PRK), laser-assisted in situ keratomileusis (LASIK) and exposure to solar light and ultraviolet radiation, ubiquinone Q10 is utilized in a collyrium pharmaceutical preparation for ocular topical administration thereof.

Mucoadhesive antimicrobial complexes of polycarbophil, i.e. a cross-linked polyacrylic acid with bioadhesive properties, and an imidazole or triazole derivative with antifungal or antiprotozoal activity, in its basic form, for use in the topical treatment of mucosal affections. The complexes are obtainable by dissolving each of the two starting products in a common solvent, then joining together the two solutions in relative amounts such as to contain the same number of equivalents of the two starting products, evaporating the solvent and then drying and, if required, pulverizing and sieving the product so obtained. Particularly preferred are formulations in gel in propylene glycol comprising an econazole-polycarbophil or omoconazole-polycarbophil complex, with an excess of polycarbophil, together with pharmaceutically acceptable carrier and excipient substances, for use as sustained release antifungals for vaginal administration.

A process for solubilizing in water and in aqueous vehicles sparingly water-soluble pharmaceutically active substances, comprising the following operations: 1) forming a complex of the pharmaceutically active substance with a pharmaceutically acceptable non-ionic polymer capable of forming complexes with the substance, and isolating the complex in solid form; 2) dissolving again the thus obtained complex in an aqueous medium by means of a pharmaceutically acceptable surfactant. The method allows to markedly increase the water-solubility of pharmaceutically active organic compounds which are intrinsically poorly or negligibly soluble in water, in order to obtain preparations that are stable in aqueous solution and contain therapeutically and commercially useful concentrations of active ingredient.
