Abstract
Prolonged parenteral release into the circulatory system of a cow of a bioactive growth hormone releasing factor at desirably effective levels can be achieved using novel compositions in which the growth hormone releasing factor is present in an aqueous liquid at a dose of at least about 50 mg and at a concentration of at least about 20 mg/ml. Preferably, the growth hormone releasing factor is present in an aqueous liquid at a dose of about 200 mg and at a concentration of about 180 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 seven (7) days.
Claims4
A method for achieving enhanced concentrations of endogenous somatotropin in the circulatory system of an animal for greater than seven (7) days which comprises parenteral administration to the animal of a substantially aqueous biologically active bovine growth hormone releasing factor analog having the amino acid sequence shown in SEQ ID NO:1 comprising at least 50 mg of said biologically active bovine growth hormone releasing factor analog in water at a concentration of at least about 20 mg/ml.
A composition comprising at least about 200 mg of a biologically active bovine growth hormone releasing factor having the amino acid sequence shown in SEQ ID NO:1 in water at a concentration of at least about 180 mg/ml to form a syringeable aqueous bovine growth hormone releasing factor solution, said solution being substantially void of absorption modifying agents and buffering agents.
A method for achieving enhanced concentrations of endogenous somatotropin in the circulatory system of an animal for greater than thirty-five (35) days which comprises parenteral administration to the animal of a substantially aqueous biologically active bovine growth hormone releasing factor analog having the amino acid sequence shown in SEQ ID NO:1 comprising at least 200 mg of said biologically active bovine growth hormone releasing factor analog in water at a concentration of at least about 180 mg/ml.
A composition comprising at least about 50 mg of a biologically active bovine growth hormone releasing factor having the amino acid sequence show in SEQ ID NO:
- 1 in water at a concentration of at least about 20 mg/ml to form a syringeable aqueous bovine growth hormone releasing factor solution, said solution being substantially void of absorption modifying agents and buffering agents.
