What does patent IL288388 cover?
Patent IL288388, titled "Method of treating neurological disorders," was filed by Teva Pharmaceutical Industries Ltd. It pertains to a novel method for treating specific neurological disorders via the administration of a combination of neuroprotective agents.
The patent's primary innovation lies in combining a known therapeutic agent, such as memantine, with another neuroprotective compound, aiming to enhance efficacy in disorders like Alzheimer's disease, Parkinson's disease, and other neurodegenerative conditions. Its claims focus on the specific combination, dosage regimen, and potential indications.
What are the key claims of IL288388?
Core Claims
- Claim 1: A method for treating a neurological disorder comprising administering an effective amount of memantine in combination with a second neuroprotective agent selected from a group including antioxidants, anti-inflammatory agents, and neurotrophic factors.
- Claim 2: The method of claim 1, where the neuroprotective agent is selected from the group consisting of alpha-lipoic acid, acetyl-L-carnitine, or coenzyme Q10.
- Claim 3: The method of claim 1 or 2, wherein the combination is administered orally at specific dosage ranges, for example, memantine 5-20 mg/day and the neuroprotective agent 100-300 mg/day.
- Claim 4: A kit comprising the combination of memantine and the specified neuroprotective agent, packaged for simultaneous or sequential administration.
Additional Claims
Dependent claims specify dosage variations, treatment durations, and specific patient populations. Claims also extend to the use of the combination for neuroprotection, cognitive improvement, and symptomatic relief in neurodegenerative diseases.
Scope of Claims
The patent claims are centered on the combination therapy and its specific application parameters. They are broad enough to cover multiple neuroprotective agents and various dosages but limited to neurological disorders as indicated.
