Description

Dronabinol (marketed as Marinol) is a synthetic form of delta-9-tetrahydrocannabinol (Δ⁹-THC), the primary psychoactive component of cannabis (marijuana). THC demonstrates its effects through weak partial agonist activity at Cannabinoid-1 (CB1R) and Cannabinoid-2 (CB2R) receptors, which results in the well-known effects of smoking cannabis such as increased appetite, reduced pain, and changes in emotional and cognitive processes. Due to its evidence as an appetite stimulant and an anti-nauseant, Dronabinol is approved for use in anorexia associated with weight loss in patients with AIDS and for the treatment of nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments Label.

Tetrahydrocannabinol (THC) and cannabidiol (CBD) are the two most abundant cannabinoids found naturally in the resin of the marijuana plant, both of which are pharmacologically active due to their interaction with cannabinoid receptors that are found throughout the body 4. While both CBD and THC are used for medicinal purposes, they have different receptor activity, function, and physiological effects. If not provided in their activated form (such as through synthetic forms like Dronabinol or Nabilone), THC and CBD are obtained through conversion from their precursors, tetrahydrocannabinolic acid-A (THCA-A) and cannabidiolic acid (CBDA), through decarboxylation reactions. This can be achieved through heating, smoking, vaporization, or baking of dried unfertilized female cannabis flowers.

From a pharmacological perspective, Cannabis' diverse receptor profile explains its potential application for such a wide variety of medical conditions. Cannabis contains more than 400 different chemical compounds, of which 61 are considered cannabinoids, a class of compounds that act upon endogenous cannabinoid receptors of the body 1. The endocannabinoid system is widely distributed throughout the central and peripheral nervous system (via the Cannabinoid Receptors CB1 and CB2) and plays a role in many physiological processes such as inflammation, cardiovascular function, learning, pain, memory, stress and emotional regulation, and the sleep/wake cycle among many others 2. CB1 receptors are found in both the central and peripheral nervous system, and are most abundant in the hippocampus and amygdala, which are the areas of the brain responsible for short-term memory storage and emotional regulation. CB2 receptors are mainly located in the peripheral nervous system and can be found on lymphoid tissue where they are involved in regulation of immune function 3.

Pharmacodynamics

Marinol may has complex effects on the central nervous system (CNS), including cannabinoid receptors. Dronabinol may inhibit endorphins in the emetic center, suppress prostaglandin synthesis, and/or inhibit medullary activity through an unspecified cortical action.

Mechanism of action

Dronabinol is a synthetic form of delta-9-tetrahydrocannabinol (Δ⁹-THC), the primary psychoactive component of cannabis (marijuana). THC demonstrates its effects through weak partial agonist activity at Cannabinoid-1 (CB1R) and Cannabinoid-2 (CB2R) receptors, which results in the well-known effects of smoking cannabis such as increased appetite, reduced pain, and changes in emotional and cognitive processes.

Absorption

Dronabinol capsules are almost completely absorbed (90 to 95%) after single oral doses. Due to the combined effects of first pass hepatic metabolism and high lipid solubility, only 10 to 20% of the administered dose reaches the systemic circulation. After oral administration, dronabinol has an onset of action of approximately 0.5 to 1 hours and peak effect at 2 to 4 hours. Following BID dosing of 2.5mg of dronabinol, Cmax was found to be 1.32ng/mL with a median Tmax of 1.00 hr.

Volume of distribution

Dronabinol has a large apparent volume of distribution, approximately 10 L/kg, because of its lipid solubility.

Protein binding

The plasma protein binding of dronabinol and its metabolites is approximately 97%.

Metabolism

THC is primarily metabolized in the liver by microsomal hydroxylation and oxidation reactions catalyzed by Cytochrome P450 enzymes. 11-hydroxy-▵9-tetrahydrocannabinol (11-OH-THC) is the primary active metabolite, capable of producing psychological and behavioural effects, which is then metabolized into 11-nor-9-carboxy-▵ 9-tetrahydrocannabinol (THC-COOH), THC's primary inactive metabolite 1. Dronabinol and its principal active metabolite, 11-OH-delta-9-THC, are present in approximately equal concentrations in plasma. Concentrations of both parent drug and metabolite peak at approximately 0.5 to 4 hours after oral dosing and decline over several days Label.

Route of elimination

Dronabinol and its biotransformation products are excreted in both feces and urine. Because of its large volume of distribution, dronabinol and its metabolites may be excreted at low levels for prolonged periods of time. Following single dose administration, low levels of dronabinol metabolites have been detected for more than 5 weeks in the urine and feces.

Half-life

The elimination phase of dronabinol can be described using a two compartment model with an initial (alpha) half-life of about 4 hours and a terminal (beta) half-life of 25 to 36 hours.

Clearance

Values for clearance average about 0.2 L/kg-hr, but are highly variable due to the complexity of cannabinoid distribution.
