Method for prolonged release of somatotropin.

摘要

Prolonged release administration of somatotropin to a domestic, food-producing animal is provided by the parenteral implantation of a shaped article comprising a solid body of compacted somatotropin which is free of binders and matrix polymers in amounts sufficient to have a substantial effect on release of the somatotropin, and which optionally has a release inhibiting barrier coating covering the article except for at least one uncoated release surface.
