Enhanced Therapeutic Composition of Intranasal Lidocaine with Improved Ergonomics and Precision Metering

The present inventive concept discloses an improved therapeutic composition of intranasal lidocaine with a preservative-free nasal spray formulation and a mechanical multi-dose nasal spray pump device featuring an enhanced ergonomic design, precision metering system, and built-in timer for consistent dosing intervals to treat pain associated with tri-geminal neuralgia, facial neuropathic pain, facial cancer induced neuropathic pain, migraine pain, and cluster headache pain.

The original patent disclosed a preservative-free intranasal composition in multi-dose or bi-dose or unit-dose spray container to treat pain associated with tri-geminal neuralgia, facial neuropathic pain, facial cancer induced neuropathic pain, migraine pain, and cluster headache pain. However, the original patent did not address the limitations of user comfort and ease of use, precision metering, and consistent dosing intervals, which are critical factors in ensuring effective treatment. The present inventive concept addresses these limitations by introducing an improved ergonomic design, precision metering system, and built-in timer to provide enhanced user comfort, accurate dosing, and consistent treatment outcomes.

The improved therapeutic composition of intranasal lidocaine comprises a preservative-free nasal spray formulation and a mechanical multi-dose nasal spray pump device. The device features an enhanced ergonomic design that provides improved user comfort and ease of use, reducing fatigue and discomfort during prolonged treatment periods. The precision metering system ensures accurate dosing of the formulation, and the built-in timer enables consistent dosing intervals, thereby optimizing treatment outcomes. The formulation itself is a supersaturated solution of lidocaine in a pharmaceutically acceptable solvent carrier, with a pH-adjusting agent to maintain the pH between about 3 and about 6. The device is designed to detect the presence of the formulation and prevent accidental actuation, with a visual indicator to display the number of remaining doses.

The present inventive concept introduces several novel features that distinguish it from the original patent, including the improved ergonomic design, precision metering system, and built-in timer. These features provide a significant improvement in user comfort, accurate dosing, and consistent treatment outcomes, thereby addressing the limitations of the original patent. The combination of these features and the preservative-free nasal spray formulation constitutes a non-obvious inventive step that provides a significant advancement in the treatment of pain associated with tri-geminal neuralgia, facial neuropathic pain, facial cancer induced neuropathic pain, migraine pain, and cluster headache pain.

Alternative embodiments of the inventive concept could include variations in the ergonomic design, precision metering system, and built-in timer to accommodate different user needs and preferences. For example, the device could be designed with adjustable ergonomic features, such as interchangeable grip sizes or angles, to accommodate users with different hand sizes or preferences. The precision metering system could be modified to accommodate different dosing regimens or formulations, and the built-in timer could be replaced with a manual or automated dosing schedule. Additionally, the inventive concept could be adapted for use with other locally active sodium channel blockers or pain relief medications.

The present inventive concept has significant commercial potential in the pharmaceutical and medical device industries, particularly in the areas of pain management and neuroscience. The improved therapeutic composition of intranasal lidocaine could be marketed as a premium product for treating pain associated with tri-geminal neuralgia, facial neuropathic pain, facial cancer induced neuropathic pain, migraine pain, and cluster headache pain. The device's enhanced ergonomic design, precision metering system, and built-in timer could provide a competitive advantage in the market, attracting users who value ease of use, accuracy, and consistent treatment outcomes.
