Abstract
Gel, powder, suspension, emulsions or film formulations for systemic delivery of insulin with improved stability and rapid onset of action are described herein. The formulations are preferably absorbed to a mucosal surface, most preferably via buccal or sublingual administration, although rectal, vaginal, nasal or ocular administration is possible. 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. Following administration, these formulations are rapidly absorbed into the blood stream. The formulation is preferably a polymeric gel, powder or film which adheres to the mucosal surface, thereby enhancing uptake of the incorporated drug. In the preferred embodiment, this formulation is administered sublingually, most preferably before a meal or after a meal.
