Description
- This application claims the priority of U.S. Provisional Application Ser. No. 60/172,685, filed Dec. 20, 1999.
- The present invention generally pertains to the delivery of unstable liquids. More particularly, but not by way of limitation, the present invention pertains to the delivery of unstable pharmaceutical preparations to the eye, ear, or nose.
- Topical pharmaceutical preparations for the eye, ear, and nose are typically formulated as a liquid solution or suspension. However, certain topical preparations have individual components that, if mixed, have a shelf life of only a few weeks. Typically, one of the components is in a powdered form, and the other component is in a liquid form. Such topical pharmaceutical preparations were initially packaged with the unstable components in two separate containers. The components were then dispensed in certain specified amounts from their separate containers into a third container and mixed just prior to delivery. Delivery of the mixed preparation was typically accomplished via a conventional dropper. Because of the inconvenience of and the risk of user non-compliance with such two container preparations, various containers were developed having two, separate compartments for the unstable components. Such containers could be manipulated by a user to mix the components just prior to delivery and then deliver the mixed preparation via an integrated nozzle. U.S. Pat. Nos. 5,474,209 and 5,782,345, which are incorporated herein in their entirety by this reference, provide examples of such containers.
- However, a need still exists in the pharmaceutical industry for an effective means of delivering unstable pharmaceutical preparations to the eye, ear, and nose. The present invention provides advantageous devices and formulations to meet this need.
- One aspect of the present invention is a device for the delivery of a pharmaceutical preparation having a first component and a second component. The device includes an upper container for receiving the first component and having a bottom. The first component includes an unstable anti-infective agent. The device also includes a lower container for receiving a second component. The second component includes a liquid carrier for the first component. The device further includes a tubular sleeve movably disposed within the upper container and a cap rotationally coupled to the upper container. When the cap is screwed onto the upper container, the tubular sleeve tears the bottom of the upper container to place the first component in communication with the second component.
- In another aspect, the device includes an upper container for receiving a first component and having a bottom. The first component includes a first pharmaceutically active agent. The device also includes a lower container for receiving a second component unstable in the first component. The second component includes a second pharmaceutically active agent. The device further includes a tubular sleeve movably disposed within the upper container and a cap rotationally coupled to the upper container. When the cap is screwed onto the upper container, the tubular sleeve tears the bottom of the upper container to place the first component in communication with the second component.
