摘要:
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.

Methods, devices and kits for sublingual drug delivery using iontophoresis are described herein. An active agent can be administered sublingually by placing a solid oral dosage form containing the active agent in the sublingual region of a patient and applying iontophoresis for a suitable period of time. Preferably up to 4 mA of current are applied to the sublingual region. Different time ranges can be used to administer iontophoresis; preferably iontophoresis is administered for up to 2 minutes at a time. Any suitable device for administering iontophoresis to the sublingual region may be used. The preferred device is a hand-held device that contains a handle, two electrodes, one of which is located on the handle and the other of which is attached to the end of the handle, and a connection to a power source. Optionally, the device contains a timer, which can be used turn off the current at a preset time. The device can be used to administer an active agent by iontophoresis to the sublingual region of a patient, by attaching the second electrode of the device to a solid oral dosage form containing the active agent to be administered. A kit contains the device for administering iontophoresis and one or more solid oral dosage forms, preferably in the form of one or more tabs or wafers. The tabs or wafers may be completely dissolvable or edible, or may contain a non-edible and non-dissolvable component. In a preferred embodiment, the solid oral dosage form contains insulin or an analog thereof and one or more excipients, preferably EDTA and citric acid.

A drug delivery device that aerosolizes a dry powder formulation so that it forms a fine coating in the oral cavity and, more specifically, in the sublingual region of the oral cavity is described herein. In the preferred embodiment, the device contains five main parts: (i) a compressed gas canister, (ii) a dispenser body (also referred to herein as the main housing), (iii) a means for storing one or more doses of a drug formulation, (iv) a means for releasing a dose of the drug formulation such as a gas canister or spring piston and (v) a mouthpiece. Preferred configurations include circular, tubular, and rectangular. The means for storing the drug formulation may be configured to separately store one or more materials. In one embodiment, the means for storing the active agent is in the form of one or more drug discs, where the drug discs contain a plurality of blister packs, each storing one dose of the drug formulation. In another embodiment, the means for storing the active agent is a dosage cartridge containing a single dose of the drug formulation. In yet another embodiment, the drug formulation is stored on a ribbon containing a plurality of blister packs, each storing one dose of the drug formulation.

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.

Drug formulations for systemic drug delivery with improved stability and rapid onset of action are described herein. The formulations may be administered via buccal administration, sublingual administration, pulmonary delivery, nasal administration, subcutaneous administration, rectal administration, vaginal administration, or ocular administration. In the preferred embodiments, the formulations are administered sublingually or via subcutaneous injection. The formulations contain an active agent and one or more excipients, selected to increase the rate of dissolution. In the preferred embodiment, the drug is insulin, and the excipients include a metal chelator such as EDTA and an acid such as citric acid. Following administration, these formulations are rapidly absorbed by the oral mucosa when administered sublingually and are rapidly absorbed into the blood stream when administered by subcutaneous injection. In one embodiment, the composition is in the form of a dry powder. In another embodiment, the composition is in the form of a film, wafer, lozenge, capsule, or tablet. In a third embodiment, a dry powdered insulin is mixed with a diluent containing a pharmaceutically acceptable carrier, such as water or saline, a metal chelator such as EDTA and an acid such as citric acid. Devices for storing and mixing these formulations are also described.
摘要:
Compositions and methods for modulating the pharmacokinetics and pharmacodynamics of rapid acting injectable insulin formulations are described herein. In the preferred embodiment, the formulations are administered via subcutaneous injection. The formulations contain insulin in combination with a zinc chelator such as ethylenediaminetetraacetic acid (“EDTA”) and a dissolution/stabilization agent, and optionally additional excipients. Calcium disodium EDTA is less likely to remove calcium from the body, and typically has less pain on injection in the subcutaneous tissue. Modulating the type and quantity of EDTA can change the insulin absorption profile. Increasing the quantity of citrate can further enhance absorption and chemically stabilize the formulation. In the preferred embodiment, the formulation contains human insulin, calcium disodium EDTA and a dissolution/stabilization agent such as citric acid or sodium citrate. These formulations are rapidly absorbed into the blood stream when administered by subcutaneous injection.

摘要:
It has been discovered that by combining a chelator, such as ethylenediaminetetraacetic acid, with an acidifier, such as citric acid, the insulin is absorbed much more rapidly than in the absence of the chelator and acidifier, with a commercially available rapid, intermediate or long lasting insulin such as glargine, one can increase and/or prolong the bioavailability of the insulin mixture. The formulations are suitable for administration by injection or to a mucosal surface such as the pulmonary or oral regions, although subcutaneous injection is preferred.
