Biologically degradable polyamide for depot preparations having controlled release of the active compound |
摘要 |
Polyamides in which amino acids are incorporated in the polymer backbone via two amino or carboxyl groups and which carry in the alpha -position to the amide structure a functional group which is responsible for degradation and active compound release are highly suitable for the preparation of biologically degradable active compound depot preparations having controlled release of the active compound.
