US Classification:

514 58, 554214, 554117, 514530, 5147724, 424488

Abstract:

This invention relates to a method of reducing an irritating or adverse side effect associated with the topical use of an active ophthalmic drug comprising incorporating an effective amount of a cyclodextrin or cyclodextrin derivative into a formulation to complex the active drug such that the concentration of the free active drug is reduced below a tolerable threshold, and incorporating an effective amount of a viscosity increasing agent in said formulation such that the bioavailability of said drug is high enough to be therapeutically effective, wherein the cyclodextrin or cyclodextrin derivative is not required to solubilize the active drug. Another aspect of this invention relates to topical ophthalmic formulations comprising an active drug, a cyclodextrin or cyclodextrin derivative, and a viscosity-enhancing agent, in effective amounts as stated above.

International Classification:

H04J003/06

G06F001/12

US Classification:

370516, 370503, 370506, 375372, 713400

Abstract:

The invention provides a novel scheme to align data streams across multiple transmission channels and match multiple transmissions with one receiving rate. The channel aligning aspect of this invention detects the occurrence of an aligning character in a plurality of input channel character streams, buffers the character stream until an aligning character has been detected on every input channel. The channel aligning system transmits filler characters over every output channel corresponding to an input channel where an aligning character has been received if an aligning character has not been detected on every input channel. The aligning system then synchronously transmits the buffered characters, starting with the aligning character and proceeding with the subsequently received characters. The rate matching aspect of this invention receives a plurality of character streams synchronized by a first clock and buffers the character streams. Buffered characters are then transmitted over one or more output channels synchronized by a second clock.

Assignee:

Allergan, Inc. - Irvine CA

International Classification:

A61K 31/47

US Classification:

424 7804, 514 57, 514912

Abstract:

Ophthalmic compositions include an ophthalmically acceptable carrier component, for example, an aqueous-based carrier, and a plurality of polyanionic component portions having different molecular weights. In one embodiment, the polyanionic component includes a first polyanionic component portion having a first molecular weight; and a second polyanionic component portion having a different second molecular weight. Each of the first and second polyanionic component portions is present in an amount effective to provide lubrication to an eye when the composition is administered to an eye. Methods of making and using such compositions are also disclosed.
