Overcoming Pharmacokinetic and Peripheral Safety Challenges in Psychedelic Therapies: The Promise of Advanced Drug Delivery Systems.
ACS pharmacology & translational science June 12, 2026 Tianshu Zhang, Cong Lin, Xiaohui Wang
Classic serotonergic psychedelics like LSD, psilocybin, and DMT show promise for treating neuropsychiatric disorders but are limited by first-pass metabolism, erratic pharmacokinetics, and off-target effects. Advanced delivery systems—including transdermal and microneedle patches, intranasal sprays, sublingual films, and injectable formulations—along with molecular strategies such as prodrugs and selective receptor bias, bypass hepatic metabolism, enable precise control over onset and duration, and minimize peripheral activation. Preclinical and early clinical evidence indicates gains in bioavailability, half-life extension, and conversion of fleeting effects into manageable windows, offering a path to safer, patient-centered therapies despite regulatory and trial-design challenges.
