II. Indications: Synthetic Tetrahydrocannabinol (THC)
- See Cachexia in Cancer
- See Geriatric Failure to Thrive
- See Nausea in Terminally Ill Patients
- Anorexia in Chronic Renal Failure
- Chemotherapy induced Nausea or Vomiting
- Cachexia in AIDS
III. Indications: Purified Cannabidiol (CBD, Epidiolex)
IV. Mechanism: Two product types derived from Marijuana and hemp
- Synthetic Tetrahydrocannabinol (THC)
- Will generate a positive Urine Drug Screen
- Purified Cannabidiol (CBD)
- Does not cause the "high" seen with THC
- Typically will not generate a positive Urine Drug Screen (but may if trace THC in product)
V. Preparations: Cannabidiol (CBD)
- Epidiolex oral solution
- FDA approved in U.S. as of 2018, with a cost of $32,000/year
- OTC products (various forms)
- Legal status depends on U.S. State
- Not regulated or studied for efficacy and safety
VI. Preparations: Synthetic Tetrahydrocannabinol (THC)
- Nabilone (Cesamet, FDA CII) 1-2 mg orally every 12 hours
- Dronabinol
- Marinol capsules (FDA CIII as misuse is less likely due to formulation)
- Dose: 5-10 mg orally, rectally or sublingual every 6-8 hours
- Syndros liquid (FDA CII)
- Marinol capsules (FDA CIII as misuse is less likely due to formulation)
VII. Drug Interactions: Cannabidiol (CBD)
- Cannabidiol inhibits CYP2C19, CYP2C8, CYP2C9
- Increases levels of Citalopram, Phenytoin, Amitriptyline, Valproic Acid, Warfarin
- Cannabidiol levels may be lowered
- Strong CYP3A4 Inducers lower CBD levels (e.g. St. John's Wort, Carbamazepine, Phenytoin, Rifampin)
- Strong CYP3A4 inhibitors raise CBD levels (e.g. Clarithromycin)
VIII. Adverse Effects: CBD
- Drowsiness or sedation (esp. in combination with other CNS Depressants)
- Diarrhea
- Liver Function Test abnormalities
IX. Safety
- Avoid THC and CBD in pregnancy, Lactation and those taking multiple medications
- Check CBD product for a certificate of analysis that reports CBD levels, THC levels and contaminants

Ontology: nabilone (C0068333)
| Definition (NCI) | A synthetic cannabinoid and dibenzopyrane derivative with anti-emetic activity. Although the mechanism of action has not been fully elucidated yet, it has been suggested that nabilone is a highly selective and strong agonist for the cannabinoid receptors CB1 and CB2, both of which are coupled to Gi/o proteins. The CB1 receptors are expressed predominantly in central and peripheral neurons and receptor stimulation has been implicated in the reduction of chemotherapy-induced nausea. |
