NIH/NIDA 159 Therapeutic Cannabidiol Pulmonary Delivery Device
sbir.nih.gov/sites/default/files/PHS2016-1.pdfPage 122 +
Objective
To develop a pulmonary delivery device that can administer therapeutic doses of the non-psychoactive cannabinoid
CBD. The ultimate goal is to generate a sufficiently characterized clinical tool such that the Food and Drug
Administration (FDA) would allow it to be used to evaluate the efficacy of inhaled CBD as a therapeutic agent in
clinical trials.
This opportunity is open to all Small Business Innovation Research (SBIR) award-eligible organizations. However,
it is ANTICIPATED that a Small Business Concern (SBC) best equipped to produce such a characterized device and data
package within the time and budget constraints MIGHT CURRENTLY be marketing a similar or related inhalation product

Background
CBD is a compound found in marijuana that has no euphoric properties but appears to have other pharmacological
activities. Current understanding of CBD pharmacology is limited; a number of laboratory studies have been
conducted and a few have progressed into early clinical phase investigations, the most successful demonstrating
CBD as an anxiolytic agent. Potential applications for the anxiolytic properties of CBD include reduction of craving
and relapse in Substance Use Disorders, and reduction of anxiety in Post-Traumatic Stress Disorder. In addition,
CBD is currently under clinical investigation for the treatment of childhood intractable epilepsies, where it is added
to the existing medication regimen (usually, to 2-3 other drugs). However, CBD is well known as an inactivator of
drug metabolizing enzymes and so can significantly disturb the patient’s exposure to their current medications and
potentially contribute to serious drug interactions. If CBD is to be administered via a pulmonary (inhaled)
mechanism rather than via oral route, the liver exposure would be much lower, resulting in less enzyme inactivation
and drug-drug interactions. Furthermore, inhaled CBD provides 2-3x greater bioavailability and shows substantially
lower inter-dose and inter-subject variability than with oral administration. when used in a clinical trial a pulmonary
delivery device would result in more reproducible CBD dosing, less risk of drug interactions and ultimately less
variable and more reproducible clinical data
i just wanted to add some information on CBD and the attention it gets recently !
