• Dosage ranges (e.g., 10 mg to 200 mg per day).
• Methods of administration (oral, intravenous, or injectable).
• Specific treatment regimens (e.g., once or twice daily).
• Conditions treated (neuropathic pain, multiple sclerosis, Parkinson’s disease).

Claims 6–10:
Focus on the pharmaceutical composition:

• Composition includes the active compound, a pharmaceutically acceptable carrier, and optional excipients.
• The formulation may be in tablet, capsule, or injectable form.
• Stability and bioavailability enhancements are specified.

Claim 11:
A method of synthesizing the compound, emphasizing a novel synthetic pathway that reduces manufacturing costs.

Claim 12:
A kit comprising the pharmaceutical composition and instructions for use in treating the specified neurological conditions.
