1. An anti-ulcer composition having rapid delivery and enhanced adherence to ulcer-bearing tissue comprising:
- a solid matrix having suspended therein an anti-ulcer medicament, said matrix formed by flash-flow melt-spinning a mixture ofi) a melt-spinnable carrier material present in an amount sufficient to form a flash-flow melt-spun matrix when said anti-ulcer medicament is dispersed therein;
ii) an anti-ulcer medicament present in an amount sufficient to achieve a therapeutic effect; and
iii) a hydrogel in addition to said carrier material, said hydrogel being selected from the group consisting of gums, cellulose, pectins, gelatin, polycarbophil, alginate and mixtures thereof to provide mucosal adherence.
