Curator's Comment: description was created based on several sources, including http://www.who.int/medicines/areas/quality_safety/4.2DronabinolCritReview.pdf

Dronabinol also known as (−)-trans-delta9-tetrahydrocannabinol is an active ingredient of cannabis. The drug was approved by FDA for the treatment of anorexia in patients with AIDS and chemotherapy-induced nausea and vomiting. Dronabinol exerts its action by activating CB1 and CB2 recepors which makes it a CNS active medicine.

Sample Use Guides

In Vivo Use Guide

Appetite Stimulation: Initially, 2.5 mg capsules should be administered orally twice daily, before lunch and supper. For patients unable to tolerate this 5 mg/day dosage, the dosage can be reduced to 2.5 mg/day, administered as a single dose in the evening or at bedtime. Antiemetic: it is best administered at an initial dose of 5 mg/m2, given 1 to 3 hours prior to the administration of chemotherapy, then every 2 to 4 hours after chemotherapy is given, for a total of 4 to 6 doses/day. Should the 5 mg/m2 dose prove to be ineffective, and in the absence of significant side effects, the dose may be escalated by 2.5 mg/m2 increments to a maximum of 15 mg/m2 per dose.
