Abstract: The invention relates to topical ophthalmic preparations in eye drops containing bimatoprost as an active ingredient at the concentration of 0.1 mg/ml, wherein the presence of benzalkonium chloride is limited to the indispensable minimum commonly required for its activity as an antimicrobial preservative, i.e. from 50 at 80 ppm, and the bioavailability of the product is ensured by the addition of specific non-ionic surfactants, i.e., poloxamers.

Abstract: The present invention describes topical formulations for use in photodynamic therapy (PDT) of skin affections, said formulations comprising a Zn-phthalocyanine derivative.

Abstract: 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.
