Compositions and methods for modulating injection site pain associated with rapid acting injectable insulin formulations have been developed for subcutaneous injection. The formulations contain insulin in combination with a zinc chelator such as ethylenediaminetetraacetic acid (“EDTA”), a dissolution/stabilization agent such as citric acid, a magnesium salt, and, optionally, additional excipients. New presentations include rapid acting concentrated insulin formulations and a way to enhance the absorption of commercially available rapid acting analog formulations by mixing them with a vial containing dry powder excipients that accelerate their absorption. Devices for mixing excipient and insulin together at the time of administration, while minimizing residence time of the mixture, are also described.

Injectable insulin formulations that are capable of modifying the amount of insulin released based on the patient's tissue glucose levels, methods for making and using these formulations are described herein. The formulation may be administered via subcutaneous, intradermal or intramuscular administration. In one preferred embodiment, the formulations are administered via subcutaneous injection. The formulations contain insulin, an oxidizing agent or enzyme and a reducing agent or enzyme, a diluent and optionally one or more thickening agents. If a thickening agent is present in the formulation, the thickening agent increases the viscosity of the formulation following administration. Preferably the formulation contains an insulin, a diluent, glucose oxidase and peroxidase. Following administration to a patient, the insulin is released from the formulations as a function of the patient's tissue glucose level, which in turn maintains the patient's blood glucose level within an optimum range. The formulation is often referred to as a “smart” formulation since it modifies its release rate of insulin according to the patient's needs at a particular time. In a preferred embodiment, the formulation is designed to release insulin into the systemic circulation over time with a basal release profile following injection in a patient. In another embodiment, the formulation is designed to release insulin into the systemic circulation over time with a non-basal release profile following injection in a patient, such as a regular human insulin release profile or a prandial release profile.

Injectable insulin formulations with improved stability and rapid onset of action are described herein. The formulations may be for subcutaneous, intradermal or intramuscular administration, In the preferred embodiment, the formulations are administered via subcutaneous injection. The formulations contain insulin in combination with a chelator and dissolution agent, and optionally additional excipients. In the preferred embodiment, the formulation contains human insulin, a zinc chelator such as EDTA and a dissolution agent such as citric acid. These formulations are rapidly absorbed into the blood stream when administered by subcutaneous injection. In the preferred embodiment, the insulin is provided as a dry powder in a sterile vial. This is mixed with a diluent containing a pharmaceutically acceptable carrier, such as water, a zinc chelator such as EDTA and a dissolution agent such as citric acid shortly before or at the time of administration. In another embodiment, the insulin is stored as a frozen mixture, ready for use upon thawing.
