Dronabinol is a synthetic form of delta-9-tetrahydrocannabinol (THC), the principal psychoactive constituent of cannabis. It is used primarily as an antiemetic in the treatment of chemotherapy-induced nausea and vomiting and as an appetite stimulant in AIDS-related anorexia. Dronabinol is approved for these uses in several countries including the United States.
Pharmacokinetics
Pharmacokinetic parameters reported in healthy adult volunteers (both sexes), single oral administration.
