Claims10
A method for providing a topical timed release of a medicament for the eyeball of an animal in need thereof which comprises:
- (a) providing a composition which comprises:
- a medicament;
- and a chemically modified polysaccharide (CMP) comprising linked saccharide rings with ring opened saccharide units at C2 and C3 bond and containing carboxylic acid moieties or water dispersible salt as a random copolymer wherein the CMP is water dispersible to form a clear solution as a time release adjuvant for the medicament;
- and
- (b) topically providing the medicament on the eyeball to provide the timed release.
