A substantially anhydrous foamable composition capable of forming a substantially stable foam on contact with water is formed from a mixture of water soluble polysaccharide gum, an effervescent base and a biocompatible gelling salt. These compositions upon contact with water form extremely stable foams which are capable of acting as carriers for pharmaceutically active compositions.
