Benefits of technology

The kit effectively reduces medication degradation, ensuring stable storage and easy self-administration of precise doses, enhancing safety and convenience for users while maintaining medication potency.

Problems solved by technology

DHE (as with other medicaments), however, degrades when exposed to oxygen.
Breaking the ampoule may be hazardous because it may produce shards of glass or particles that may mix with the medication and be injected or inhaled by the migraine sufferer.
While the ampoule is open and prior to insertion in either the syringe or the nasal sprayer, the DHE is exposed to oxygen, which can lead to degradation of the DHE.
As such, the sufferer may improperly administer the correct dosage of medication or take an over or under dosage of the medication.

Embodiment Construction

[0042]A medicament dispensing kit 1 is illustrated in FIG. 1. The kit 1 includes a sealed package 10, a medication dispensing assembly 20, and a medicament container 30. The kit 1 also includes an oxygen absorbing component 40.

[0043]The medicament container 30 will now be described in greater detail in connection with FIGS. 2-8. The medicament container 30 includes a cartridge assembly or vial 31 having an interior compartment for receiving a predetermined dose of medication. The cartridge assembly or vial 31 is preferably formed from glass. The present invention, however, is not limited to a cartridge assembly 31 formed from glass; rather, other materials that are non reactive with DHE or other oxygen sensitive medicaments and prevent the passage of oxygen there through are considered to be well within the scope of the present invention. The medicament container 30 also includes a pair of sealing assemblies 32 and 33 for sealing the open end portions of the cartridge assembly 31 as...

Abstract

A sealing assembly movable within an opening of a medicament container allows (1) gases to be vented from the container, (2) medication to be stored in the container, and (3) medication to be dispensed from the container. Methods of limiting exposure of the medication to oxygen to prevent degradation of the medication while in the medicament container are also disclosed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation of U.S. patent application Ser. No. 10 / 285,692, filed Nov. 1, 2002, now U.S. Pat. No. ______, which claims the benefit of U.S. Provisional Application No. 60 / 330,945, filed Nov. 2, 2001, and U.S. Provisional Application No. 60 / 350,972, filed Jan. 25, 2002. These disclosures are each incorporated herein in their entirety by reference.FIELD OF THE INVENTION[0002]The present invention relates to medicament dispensing mechanisms for administering a predetermined dosage of medication. In one embodiment, the present invention is directed to a medicament dispensing kit or injector used for dispensing a gas sensitive medication (e.g., dihydroergotamine (DHE) and epinephrine) that limits the exposure of the medication to the undesirable gas thereby improving and maintaining the effectiveness of the medication over time. The present invention is also directed to methods of producing a kit that limits exposure of the medicatio...
