Aqueous prolonged release formulation

摘要

Prolonged parenteral release into the circulatory system of a cow of a bioactive bovine somatotropin at desirably effective levels can be achieved using novel compositions in which the bovine somatotropin is present in an aqueous liquid at a dose of at least about 150 mg and at a concentration of at least about 50 mg/ml. The aqueous bovine somatotropin formulation provides for the sustained release of bovine somatotropin into the circulatory system of the animal for greater than three (3) days.
