Biodegradable polymers for depot preparations having controlled release of active ingredients |
摘要 |
Polyamides in which amino acids have been incorporated into the polymer backbone via two amino or carboxyl groups and which carry a functional group responsible for degradation and release of active ingredients in the alpha -position to the amide structure are highly suitable for the preparation of biodegradable active ingredient depot preparations having controlled release of active ingredients.
