Cannabinoid microemulsion microneedle systems for pain relief
Innovative microemulsion-based microneedle patches deliver cannabinoids like CBD and THC for controlled pain relief. This system enhances bioavailability and provides sustained release, overcoming challenges of poor solubility and absorption. Ideal for chronic pain management.
Overview
The proposed solution introduces a novel delivery system for cannabinoids using microemulsion-based microneedle patches. This technology addresses the challenges of cannabinoid solubility and absorption, providing a controlled and sustained release of active compounds like CBD and THC. The system is designed for transdermal delivery, offering an effective alternative for managing mild to chronic pain while ensuring precise dosage control.
Technical specifications
The core of this technology is its microemulsion formulation, which improves the bioavailability of cannabinoids by overcoming their poor aqueous solubility and extensive metabolism. The microneedle patches facilitate direct skin absorption, bypassing intestinal and hepatic barriers, and enabling sustained release. The system is flexible, allowing for customization of cannabinoid combinations and concentrations based on therapeutic needs. It is particularly advantageous for patients requiring steady-state pain relief without the variability associated with oral administration.
Technology readiness level
Currently, this technology is at TRL 4, with pure compounds prepared and formulated for pilot testing. Plans for collaboration with regional partners are in place to incorporate these formulations into microneedle systems for broader efficacy testing. Further development will focus on adjusting formulations based on trial feedback and scaling up production for phase 1 trials.
