Dronabinol (DRONABINOL): An Overview

**

**

Introduction to Dronabinol

**

Dronabinol, also known by its brand name Marinol, is a prescription medication that contains synthetic delta-9-tetrahydrocannabinol (THC), which is the active ingredient in cannabis. It is classified as a cannabinoid and is used to treat nausea and vomiting caused by chemotherapy in patients who have not responded to standard anti-nausea medications. Dronabinol is also prescribed to stimulate appetite in patients with AIDS-related anorexia.

**

How Dronabinol Works

**

Dronabinol works by activating the cannabinoid receptors in the brain, which helps to reduce nausea and vomiting and stimulate appetite. The exact mechanism of action is not fully understood, but it is believed to involve the modulation of neurotransmitter release.

**

Administration and Dosage

**

Dronabinol is available in capsule form and is taken by mouth. The dosage is individualized based on the patient's medical condition and response to treatment. Typically, the initial dose for treating nausea and vomiting is 5 mg taken one to three hours before chemotherapy, with subsequent doses every 2 to 4 hours after chemotherapy, up to a total of 4 to 6 doses per day. For stimulating appetite in AIDS patients, the initial dose is 2.5 mg taken twice daily before lunch and dinner, with the potential for dosage adjustments based on response.

**

Possible Side Effects

**

Common side effects of Dronabinol may include dizziness, drowsiness, euphoria, changes in mood, difficulty concentrating, and dry mouth. Less common but more serious side effects may include confusion, hallucinations, fast or pounding heartbeat, and severe dizziness.

**

Precautions and Contraindications

**

Dronabinol should be used with caution in patients with a history of substance abuse or psychiatric disorders. It may impair the ability to perform tasks requiring mental alertness, such as driving or operating machinery. Dronabinol is contraindicated in patients with a known hypersensitivity to synthetic THC or sesame oil, which is an ingredient in the capsule formulation.

**

Interactions with Other Medications

**

Dronabinol may interact with other medications, including CNS depressants such as alcohol, barbiturates, and benzodiazepines, which can increase the risk of drowsiness and dizziness. It may also interact with drugs that affect liver enzymes, potentially altering the metabolism of Dronabinol.

**

Storage and Handling

**

Dronabinol capsules should be stored at room temperature (15°C to 30°C) in a tightly closed container, protected from light and moisture. Patients should follow the specific storage instructions provided by their healthcare provider or pharmacist.
