ABSTRACT
Misuse of prescription opioid drugs is the leading cause of the opioid crisis and overdose-related death. Abuse deterrent formulations (ADFs) have been developed to discourage attempts to tamper with the formulation and alter the ingestion methods. However, abusers develop complex extraction strategies to circumvent the ADF technologies. For comprehensive deterrence of drug abuse, we develop tannic acid nanoparticles (NPs) that protect encapsulated opioids from solvent extraction and thermal challenge (crisping), complementing the existing formulation strategy to deter injection abuse. Here, we develop a hybrid ADF tablet (NP-Tab), consisting of iron-crosslinked tannic acid NPs encapsulating thebaine (model opioid compound), xanthan gum, and chitosan (gel-forming polymers), and evaluate its performance in common abuse conditions. NP-Tab tampered by crushing and suspended in aqueous solvents forms an instantaneous gel, which is difficult to pull or push through a 21-gauge needle. NPs insulate the drug from organic solvents, deterring solvent extraction. NPs also promote thermal destruction of the drug to make crisping less rewarding. However, NP-Tab releases thebaine in the simulated gastric fluid without delay, suggesting that its analgesic effect may be unaffected if consumed orally as prescribed. These results demonstrate that NP-Tab can provide comprehensive drug abuse deterrence, resisting aqueous/organic solvent extraction, injection, and crisping, while retaining its therapeutic effect upon regular usage.
