The invention concerns topical ophthalmic preparations in the form of eye-drops in aqueous solution, containing azithromycin (or a pharmacologically acceptable salt thereof) as active ingredient, wherein the azithromycin is solubilized and stabilized by means of β-cyclodextrins, and in particular by means of the β-cyclodextrin called sulfobutyl ether β-cyclodextrin (SBE-β-CD).The proposed preparations have a remarkably high stability, both physical and chemical, which enables its storage at room temperature for the envisaged period of validity for a commercial pharmaceutical product.
