2) Applications:

Enteric Coatings Eudragit® L 100-55 or L 30 D-55 - delivery to the duodenum (pH > 5.0). Exact pH controlled drug release can be adjusted by a combination of polymers and coating thickness.

Eudragit® L 100 - delivery to the jejunum (pH > 6.0).

Eudragit® S 100 - delivery to the intestine (pH 6.0 to 7.5), site specific drug delivery can be achieved by combining with Eudragit® L types.

Eudragit® FS 30 D - delivery to the colon (pH >7.0).

Acryl-eze® --one step dry enteric coating system, soluble at pH 5.5

Sustained Release Coatings Eudragit® RL and RS - release profile determined by the ratio of RL to RS polymers, and the film thickness applied. Taste Masking Eudragit® RD 100, pH independent, fast disintegrating film

Eudragit® E 100 and EPO, pH dependent cationic polymer, soluble in gastric fluid up to pH 5.0, swellable and permeable above pH 5.0

Rapidly disintegrating Films Eudragit® RD 100
