CAS-Nummer:1972-08-3; Delta-9-THC

Dronabinol is an orally available cannabinoid agonist, an isomer of tetrahydrocannabinol (THC), the main and most active isomer of the Cannabis sativa L. plant, with potential antiemetic, analgesic and appetite stimulant effects. Once administered, dronabinol, also known as “Delta-9-THC,” targets and binds to cannabinoid receptors (CB1/CB2) in the central nervous system (CNS).

Dronabinol acts directly on the appetite and vomiting control centers in the brain to stimulate appetite and prevent vomiting. In addition, this drug induces analgesia. Dronabinol has relatively poor bioavailability; the synthetic THC analogue nabilone, on the other hand, has better bioavailability.

In the cannabis plant, tetrahydrocannabinol is predominantly present as THC acid. Cannabigerolic acid is formed by enzymatic condensation of the two precursors geranyl pyrophosphate and olivetolic acid, which is then enzymatically rearranged into tetrahydrocannabinolic acid. With heat and UV radiation, the acid decarboxylates to form THC.

There are four stereoisomers of delta-9-tetrahydrocannabinol:

(–)-Δ9-trans-Tetrahydrocannabinol (Dronabiol)
(+)-Δ9-trans-Tetrahydrocannabinol (THC)
(–)-Δ9-cis-tetrahydrocannabinol (no psychoactivity)
(+)-Δ9-cis-tetrahydrocannabinol (no psychoactivity)
Dronabinol is the most psychoactive isomer. It is 6 to 100 times more potent than (+)-Δ9-trans-THC (THC). The cis-forms have no psychoactive effect, there are different statements about their natural occurrence.

Dronabinol is excreted hepatogenic and nephrogenic. Urine levels can be used as a marker to measure exposure to certain preparations containing parts of the cannabis plant, such as B. Marijuana to determine.

Dronabinol is prescribed as an oral cannabinoid agonist to treat nausea and vomiting associated with chemotherapy, and anorexia and weight loss in HIV/AIDS patients. But dronabinol can also be prescribed for all other areas of application within the framework of the Cannabis Act (see below Cannabis as a drug prescription).
