US Patent:

20140357554, Dec 4, 2014

Filed:

May 12, 2014

Appl. No.:

14/275749

Inventors:

- Danbury CT, US
Robert Hauser - Columbia MD, US
Errol De Souza - Cambridge MA, US
Ming Li - Yorktown Heights NY, US
Bryan R. Wilson - Brewster NY, US

International Classification:

A61K 47/02
A61K 38/28

US Classification:

514 64

Abstract:

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.
