Stabilized insulin formulations
First Claim
1. An insulin formulation comprising, in a pharmaceutically acceptable aqueous diluent and per each milliliter of formulation, from about 40 U to about 500 U of insulin, from about 1 to about 6 milligrams of a hydroxybenzene, and from about 0.05 to about 10 milligrams of a polyethylene glycol-polypropylene glycol polymer of the formula ##STR3## having an average molecular weight of about 8350 and in which the average number of ethyleneoxy units per molecule, designated by the sum of a and c, is about 150, and the average number of propyleneoxy units per molecule, designated as b, is about 30.
