Abstract

A preserved liquid aqueous pharmaceutical composition includes one or more etherified cyclodextrin derivatives, at least one water-soluble preservative, and at least one pharmaceutically active compound which is poorly water-soluble, very poorly water-soluble or water-insoluble. The liquid aqueous pharmaceutical composition provides an acceptable solubility of the pharmaceutically active compound, such as pimobendan, in aqueous solution whereby the water-soluble preservatives retain their effectiveness in the presence of the etherified cyclodextrin derivatives allowing the use in an oral administration form.
