Detailed Analysis of the Scope and Claims of United States Patent 10,864,159
Introduction
United States Patent 10,864,159, titled "Method and composition for treating ocular hypertension and glaucoma," is a significant development in the field of ophthalmology. This patent, granted on December 15, 2020, outlines a novel approach to treating ocular hypertension and glaucoma using specific ophthalmic aqueous compositions.
Background
Ocular hypertension and glaucoma are serious eye conditions that can lead to vision loss if not properly managed. Current treatments often involve medications that reduce intraocular pressure, but these can have side effects and may not be effective for all patients. The invention described in this patent aims to address these issues with a new therapeutic approach.
Patent Scope
The scope of this patent is defined by its claims, which are critical in determining the boundaries of the invention.
Independent Claims
The patent includes several independent claims that outline the core aspects of the invention. These claims focus on:
- Ophthalmic Aqueous Composition: The patent describes an ophthalmic aqueous composition containing PGF2α analogues, such as tafluprost, which are known to reduce intraocular pressure[1][2][4].
- Method of Treatment: The method involves administering the ophthalmic aqueous composition to treat ocular hypertension and glaucoma.
- Formulation Components: The claims specify the components of the composition, including the active ingredient (PGF2α analogues), preservatives (e.g., benzalkonium chloride), and stabilizers (e.g., polysorbate 80)[1].
Dependent Claims
Dependent claims further elaborate on the independent claims by specifying details such as:
- Concentration of Active Ingredients: The concentration of PGF2α analogues and other components in the composition.
- pH and Osmolarity: The pH and osmolarity of the aqueous solution to ensure it is compatible with the eye.
- Container and Packaging: The type of container and packaging used to store and dispense the composition[1].
Key Components of the Composition
Active Ingredients
The primary active ingredient is a PGF2α analogue, such as tafluprost. Tafluprost is a prostaglandin analogue that has been shown to effectively reduce intraocular pressure in patients with glaucoma[4].
Excipients and Stabilizers
The composition includes various excipients and stabilizers to enhance the stability and efficacy of the active ingredients. These include:
- Polysorbate 80: A common stabilizer used in pharmaceutical formulations.
- Benzalkonium Chloride: A preservative to prevent microbial contamination.
- Glycerine: Used to adjust the osmolarity of the solution[1].
