ABSTRACT:
Balanced pH, thermo-irreversible gels are ideal vehicles for drug delivery to a body cavity of a mammal. The gels contain a mixture of a polyoxyalkylene block copolymer or polyether together with an ionic polysaccharide which is thermo-irreversibly gelled in the presence of a counter-ion.
