Overview - Pharma THC

Description of Pharma THC

Pharmaceutical drugs [i.e., Dronabinol (Marinol®, Syndros®) and also Nabilone (Cesamet®)] containing THC correspond to a cannabis chemotype I. They represent a class of drugs produced and standardized from synthetic sources.

Here we highlight dronabinol:

  • Dronabinol is a synthetic version of THC.

  • FDA approved in 1985 for the tx of HIV/AIDS-induced anorexia & chemotherapy-induced nausea.

  • Off-label use includes chronic pain, obstructive sleep apnea, substance abuse, and withdrawal.

  • The standard dose for research is 5mg THC. The National Institute for Drug Abuse (NIDA) declared to measure and report clinical research findings using a standard unit of delta-9-tetrahydrocannabinol (THC) of 5 mg (NIDA, 2021).

  • Dronabinol is available as soft gelatin capsules: 2.5 mg (white), 5 mg (dark brown), and 10mg (orange).

  • Contraindications to dronabinol include a history of hypersensitivity reaction to sesame oil or THC derivatives.

  • The most common adverse effects may include changes in cognition, dizziness, euphoria, nausea, anxiety, vomiting, or abdominal discomfort.

  • Dronabinol has a half-life of ~4 hours.

  • An estimated lethal human dose of dronabinol (IV) is 30 mg/kg (i.e., 2100 mg/ 70 kg).

  • Dronabinol has an onset time of ~ 1/2  to 1 hour with a peak effect at 2 to 4 hours.

  • Dronabinol has not been evaluated for geriatric or pediatric use.

While Dronabinol (Marinol®, Syndros®) and Nabilone (Cesamet®) are synthetic forms of delta-9-THC, both have different molecular formulas (see names text box), resulting in diverse adverse effects potential for more information on the differences of potential adverse effects between Dronabinol (Marinol®, Syndros®) and Nabilone (Cesamet®) see below.

In this systematic review and meta-analyses of clinical trials (2022), Dronabinol presented 111 "diverse but not severe" adverse effects, while Nabilone presented 40. 

  • Occurrences of dizziness and dry mouth were most commonly noted in both Dronabinol and Nabilone treatment groups. Similarly, nausea, drowsiness, and fatigue occurred with similar frequency. 

  • However, adverse effects of dizziness, dry mouth, and headache were significantly higher in patients treated with Dronabinol.

  • Drowsiness was >7 x as frequent in patients treated with nabilone than in the placebo group.
