Insulin with a stable basal release profile
First Claim
1. A basal insulin formulation comprisinginsulin or a modified insulin,with an injectable zinc compound andan injectable precipitation enhancing compound in an effective amount to precipitate the insulin and prolong release of solubilized insulin following injection,wherein precipitation of insulin is enhanced in the formulation comprising zinc and the precipitation enhancing compound as compared to the precipitation of insulin in the presence of the zinc or precipitation enhancing compound,wherein the precipitation enhancing agent contains an ion selected from the group consisting of, calcium, magnesium, manganese, iron, and copper, used at non-toxic levels, and is in a concentration between 0.1 to 10 mg precipitation enhancing agent/ml of basal insulin formulation.

Abstract
A basal insulin formulation composed of insulin, preferably insulin glargine, injectable zinc and injectable iron compounds as precipitating and/or stabilizing agents has been developed for subcutaneous, intradermal or intramuscular administration. The formulation is designed to form a precipitate of insulin following injection, creating a slow releasing “basal insulin” over a period of 12 to 24 hours.
