New treatment option for Pain, Tolerance
Official title PK/PD of Oral and Vaporized Delta-9-Tetrahydrocannabinol (THC) in Older Adults
ClinicalTrials.gov ID: NCT05906511
What this study is testing
What is Dronabinol 5 MG?
Dronabinol 5 MG is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for pain, tolerance.
Also referred to as "Marinol".
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The overarching goal of this double-blind, placebo-controlled, crossover study is to characterize the pharmacokinetic (PK) and pharmacodynamic (PD) effects of the main analgesic and psychoactive constituent of cannabis, delta-9 tetrahydrocannabinol (THC), among older adults - the fastest growing population of cannabis consumers, and the most likely age cohort to use cannabinoids to relieve pain. This protocol includes two sub-studies, each randomizing 20 men and women aged 65 years or older to receive two administration routes of THC; oral administration and vaporized administration.
- Phase 1: an early, usually small safety study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
