THC Inhaler Dosing Control for Pain Relief Without Psychoactive Peaks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for delivering THC for neuropathic pain relief lack standardization, leading to variability in pharmacokinetics and potential adverse effects, with high doses causing significant psychoactive effects and low doses being ineffective.
Innovation Solution
A system and method for controlled pulmonary delivery of low doses of THC, using an inhaler device with a controller to manage delivery schedules and amounts, ensuring a therapeutic window is maintained by limiting the total THC intake to 0.75 mg or less per 2 hours and 10 mg over 24 hours, with optional inclusion of additional active substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high doses of THC are delivered for pain relief, then analgesic efficacy is improved, but psychoactive effects and adverse reactions increase
Solution Approach 1:
The patent applies parameter changes by precisely controlling the dosage of THC delivered through the inhaler device. The system delivers low doses (0.2-2 mg) of THC in controlled increments, changing the dosage parameter from traditional high doses to low doses, thereby achieving pain relief while minimizing psychoactive effects. The controller manages delivery schedules and amounts to maintain THC intake within 0.75 mg or less per 2 hours and 10 mg over 24 hours.
Solution Approach 2:
The patent applies partial action by delivering only the minimum necessary amount of THC required for analgesic effect. Instead of delivering full or high doses, the system delivers partial doses (0.2-2 mg) that are sufficient for pain relief but insufficient to cause significant psychoactive effects. This partial action approach allows the system to achieve therapeutic benefits while avoiding harmful over-dosing.
2Object-affected harmful factors
If low doses of THC are delivered to minimize psychoactive effects, then safety is improved, but analgesic efficacy may be insufficient
Solution Approach 1:
The patent applies continuity of useful action by delivering THC in repeated controlled doses over extended periods. The controller manages delivery schedules to provide continuous low-dose THC administration (0.2-2 mg per delivery event, with limits of 0.75 mg per 2 hours and 10 mg per 24 hours). This continuous action maintains therapeutic levels in the body for pain relief while preventing accumulation to psychoactive levels.
Solution Approach 2:
The patent applies periodic action by delivering THC at scheduled intervals rather than continuously. The controller manages periodic delivery events spaced appropriately to maintain analgesic efficacy while allowing metabolism between doses. The system delivers low doses at controlled frequencies, ensuring therapeutic effect persists without reaching psychoactive thresholds.
3Stability of the object's composition
If standardized delivery schedules are implemented, then pharmacokinetic consistency is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by implementing automated controller management that independently tracks and enforces dosage limits without requiring user intervention. The controller automatically manages delivery schedules, monitors cumulative THC intake, and prevents excessive dosing based on pre-programmed limits (0.75 mg per 2 hours, 10 mg per 24 hours). This self-managing system ensures pharmacokinetic consistency while keeping the user interface simple.
Solution Approach 2:
The patent applies feedback by implementing a control system that continuously monitors delivered THC amounts and adjusts subsequent deliveries based on cumulative intake. The controller tracks each delivery event and uses this feedback to ensure total THC remains within safe limits. This feedback mechanism maintains pharmacokinetic consistency by preventing both under-dosing and over-dosing while managing device complexity through automated calculation and control.

AI summary
Some embodiments of the invention relate to a system for delivering to a subject at least one pre-determined amount of THC, the system comprising: a memory which stores a scheduled regimen for delivery of THC to the subject, the scheduled regimen defining: a maximal amount of THC to be delivered, the amount being 0.75 mg THC or less, and a time period within which that amount is delivered, the time period being 2 hours or longer; a decision module which decides, according to the scheduled regimen, if a delivery should take place; and an inhaler device for delivering THC to the subject, the inhaler device comprising a controller which carries out delivery of THC based on the decision made by the decision module.
