摘要
Non-aq. compsn. comprises at least 10wt.% of a biologically active polypeptide (I) and, as a continuous phase of the compsn., a biocompatible oil (II). Also claimed is a non-aq. compsn. of 15-40wt.% of a bovine somatotropin (Ia) chemically associated with zinc, 2-5wt.% of an aluminium mono- or di-stearate (IIIa) and, as a continuous phase of the compsn., a biocompatible vegetable oil. (Ia) has a particulate median vol. dia. of no greater than 5 microns and is present in a wt. ratio to the stearate of at least about 3. (Ia) chemically associated with non-toxic polyvalent metal is also new, pref. 0.3-2wt.% zinc.
