  • Publication number: 20170128542
    Abstract: Stabilized glucagon formulations are provided, in the form of a clear solution. The formulations include glucagon in a non-aqueous diluent and an antioxidant The diluent and antioxidant are selected to provide a glucagon formulation with increased stability when compared to glucagon without the anti-oxidant and/or the diluent and which shows a comparable onset of action and duration of glucose response. The compositions can be used to treat subjects with very low blood sugar (severe hypoglycemia) that can happen in subjects who have diabetes and use insulin.

  • Patent number: 9610329
    Abstract: A formulation composed of a sugar such as glucose and a surfactant such as myristoyl lysophosphocholine (LMPC) has been designed to stabilize both hydrophilic and hydrophobic portions of the glucagon molecule, under prolonged physiological conditions, in a formulation that is sufficiently similar to the pH and osmolarity of plasma so as not to induce or to minimize site irritation. The combination of a simple sugar and an surfactant stabilizes the glucagon molecule in an aqueous solution for seven days at 37° C.

  • Publication number: 20140336610
    Abstract: Methods and devices for delivering variable amounts of a drug formulation directly from a drug delivery device without requiring point of use reconstitution as a separate mixing step are described herein. These methods and devices increase the convenience, speed and simplicity of administration of drug formulations. The devices mix two or more components in a constant mixing ratio effectively simultaneous to administration, and allow for variable doses while retaining the desired ratio of the components in each dose. The devices are particularly useful for administering drug formulations that are unstable at room temperature in liquid form. The methods described herein generally use conventional devices that have been modified to administer an unstable compound and provide acceptable storage stability. Typical devices include infusion sets, pump reservoirs, syringes, pens, vials and cartridges.

  • Patent number: 8394414
    Abstract: Drug delivery to the pulmonary system has been achieved by encapsulation of the drug to be delivered in microparticles having a size range between 0.5 and ten microns, preferably in the range of two to five microns, formed of a material releasing drug at a pH of greater than 6.4. In a preferred embodiment, the drug delivery system is based on the formation of diketopiperazine microparticles which are stable at a pH of 6.4 or less and unstable at pH of greater than 6.4, or which are stable at both acidic and basic pH, but which are unstable at pH between about 6.4 and 8. Other types of materials can also be used, including biodegradable natural and synthetic polymers, such as proteins, polymers of mixed amino acids (proteinoids), alginate, and poly(hydroxy acids). In another embodiment, the microparticles have been modified to effect targeting to specific cell types and to effect release only after reaching the targeted cells.

  • Patent number: 7794754
    Abstract: Improved methods for forming fine particles of a material have been developed, wherein the method steps include dissolving the material in a solvent to form a dilute solution, immobilizing the dilution solution, and then removing the solvent to yield particles of the material. Methods of immobilizing the dilute solution include freezing, gelation, and chelation. In a preferred embodiment, the immobilized solvent is removed by lyophilization, i.e. reducing the ambient pressure while avoiding application of sufficient heat to power a phase transition. Essentially any material and solvent for the material can be used in the methods described herein. Proteins and peptides in an aqueous solvent are the preferred systems.
