Brand Names: US
  • Marinol;
  • Syndros
Pharmacologic Category
  • Antiemetic;
  • Appetite Stimulant;
  • Cannabinoid
Dosing: Adult

Note: Use caution when increasing the dose of dronabinol because of the increased frequency of dose-related adverse reactions at higher dosages.

Anorexia in patients with AIDS

Anorexia in patients with AIDS: Oral:

Capsules: Initial: 2.5 mg twice daily (1 hour before lunch and dinner); for patients unable to tolerate this dosage, may reduce to 2.5 mg once daily (1 hour before dinner or at bedtime to reduce the risk of CNS symptoms). May increase dose gradually based on response and tolerability (maximum: 20 mg per day [in divided doses]).

Oral solution: Initial: 2.1 mg twice daily (1 hour before lunch and dinner); although most patients respond to this dose, if further therapeutic effect is desired and if tolerated, may gradually increase to 2.1 mg 1 hour before lunch and 4.2 mg 1 hour before dinner, and then (if needed) to 4.2 mg twice daily (1 hour before lunch and dinner). Maximum: 16.8 mg per day [in 2 divided doses]. In patients unable to tolerate 2.1 mg twice daily, consider 2.1 mg once daily (1 hour before dinner or at bedtime) to reduce the risk of CNS effects.

Chemotherapy-induced nausea and vomiting

Chemotherapy-induced nausea and vomiting (manufacturer's labeling): Oral:

Capsules: 5 mg/m2 administered 1 to 3 hours before chemotherapy, then give 5 mg/m2/dose every 2 to 4 hours after chemotherapy for a total of 4 to 6 doses/day; increase dose in increments of 2.5 mg/m2 based on response and tolerability (maximum: 15 mg/m2/dose). Monitor for adverse reactions; consider reducing dose to 2.5 mg once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS adverse reactions.

Oral solution: Initial: 4.2 mg/m2 (rounded to the nearest 0.1 mg increment [or to the nearest 0.1 mL measurable increment on the calibrated oral dosing syringe]) 1 to 3 hours prior to chemotherapy and then every 2 to 4 hours after chemotherapy for a total of 4 to 6 doses/day. Titrate dose in 2.1 mg/m2 increments (during a cycle or in subsequent cycles) to clinical response. Maximum: 12.6 mg/m2/dose and 4 to 6 doses/day. In patients unable to tolerate 4.2 mg/m2, consider 2.1 mg/m2 once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS effects.

Chemotherapy-induced nausea and vomiting, refractory

Chemotherapy-induced nausea and vomiting, refractory (off-label dosing): Oral: Capsules: 2.5 to 10 mg 3 or 4 times daily (Lohr 2008).

Obstructive sleep apnea, moderate to severe

Obstructive sleep apnea, moderate to severe (off-label use): Oral: 2.5 mg or 10 mg 1 hour before bedtime. An initial dose escalation is required for the 10 mg dose: Initiate at 2.5 mg 1 hour before bedtime for 7 days, followed by 5 mg 1 hour before bedtime for 7 days, and then 10 mg 1 hour before bedtime (Carley 2018).

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Dosing: Kidney Impairment: Adult

There are no dosage adjustments provided in the manufacturer's labeling.

Dosing: Hepatic Impairment: Adult

There are no dosage adjustments provided in the manufacturer's labeling.

Dosing: Pediatric

(For additional information see "Dronabinol: Pediatric drug information")

Note: Use caution when increasing the dose of dronabinol because of the increased frequency of dose-related adverse reactions at higher dosages. Dronabinol is available in capsules and an oral solution; they are not bioequivalent and should not be used interchangeably on a mg:mg basis. Pediatric dosing is based on experience with the capsule formulation.

Nausea and vomiting, refractory; chemotherapy-induced nausea and vomiting or palliative care

Nausea and vomiting, refractory; chemotherapy-induced nausea and vomiting (CINV) or palliative care: Limited data available: Note: Although use of dronabinol for refractory CINV is not described as a therapeutic option in consensus reports, it may be necessary for some patients (Dupuis 2003; Flank 2016; Rower 2021). Initiate with the lowest recommended dose and titrate to response.

Children ≥6 years and Adolescents: Oral: Capsules: 2.5 to 5 mg/m2/dose every 3 to 4 hours (Ullrich 2020); calculated dose should be rounded to the nearest 2.5 mg increment (Rower 2021). In adults, usual fixed doses are 2.5 to 10 mg (Lohr 2008). Due to increased risk of adverse effects, some experts suggest avoiding use in children <6 years and using with caution in patients 6 to 12 years (Orkin 2009).

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Dosing: Kidney Impairment: Pediatric

All patients: There are no dosage adjustments provided in the manufacturer's labeling.

Dosing: Hepatic Impairment: Pediatric

Controlled Substance

Marinol: C-III; Syndros: C-II

Administration: Adult

Capsules:

Anorexia in patients with AIDS: Administer twice-daily doses 1 hour before lunch and dinner; administer single doses 1 hour before dinner or at bedtime.

Chemotherapy-induced nausea and vomiting: Administer the first dose on an empty stomach at least 30 minutes before eating; subsequent doses may be administered without regard to meals, although once titrated, the timing of administration in relation to meals should be kept consistent for each chemotherapy cycle.

Oral solution: Always use the provided calibrated oral dosing syringe when administering to ensure dose is measured and administered accurately. If the prescribed dose is >5 mg, the total dose will need to be divided and drawn up in 2 or more portions using the oral syringe. Administer orally directly from oral dosing syringe; immediately follow with a full glass of water (180 to 240 mL). May also be administered through silicone-based enteral feeding tubes that are size ≥14 French (eg, nasogastric [NG], gastrostomy tube [G-tube], percutaneous endoscopic gastrostomy tube [PEG-tube], and gastro-jejunostomy tube [GJ-tube]); do not use polyurethane tubing; after administration, flush feeding tube with 30 mL of water using a catheter-tip syringe.

Anorexia in patients with AIDS: Administer 1 hour before lunch and 1 hour before dinner initially; if persistent or severe CNS adverse effects occur, administering later in the day (1 hour before dinner and at bedtime) may reduce the frequency of CNS adverse effects.

Chemotherapy-induced nausea and vomiting: The first dose should be administered on an empty stomach at least 30 minutes prior to eating; subsequent doses within a chemotherapy cycle may be administered without regard to meals. Once a dose has been titrated, the timing of doses with regard to food in subsequent cycles should maintain consistency with prior cycles.

Administration: Pediatric

Oral:

Contraindications

Hypersensitivity to dronabinol, sesame oil (capsules), alcohol (oral solution) or any component of the formulation; receiving, or have recently received, disulfiram- or metronidazole-containing products within 14 days (oral solution).

Warnings/Precautions

Concerns related to adverse effects:

• Cardiovascular effects: May cause occasional hypotension, possible hypertension, syncope, or tachycardia; patients with cardiac disorders may be at higher risk for hemodynamic instability. Monitor for changes in heart rate, blood pressure, and for signs/symptoms of syncope after initiating treatment and with dosage increases. Avoid concomitant use with other medications associated with similar cardiovascular adverse effects.

• CNS adverse effects: Monitor for CNS adverse effects; may require dosage modification. Dronabinol has been reported to exacerbate depression, mania, or schizophrenia; screen patients for history of these conditions prior to treatment initiation. Significant CNS symptoms were associated with doses of 0.4 mg/kg in antiemetic studies. Avoid use in patients with a psychiatric history; if use cannot be avoided, monitor for new or worsening psychiatric symptoms. Avoid concomitant use with other medications associated with similar psychiatric adverse effects. May cause cognitive impairment, altered mental state, or CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery, driving). Elderly and pediatric patients may be more sensitive to neurologic and psychiatric effects of dronabinol. May require dose reduction or discontinuation.

• GI effects: New or worsening paradoxical nausea, vomiting, and/or abdominal pain may occur with synthetic cannabinoids; may be severe. Symptoms are similar to cannabinoid hyperemesis syndrome, which is a cyclical syndrome with the same symptoms occurring with long-term use of cannabinoid products. Monitor patients for specific related symptoms; development of worsening nausea, vomiting or abdominal pain may require dose reduction or discontinuation.

• Hypersensitivity: Hypersensitivity reactions, including disseminated rash, hives, lip swelling, oral lesions, skin burning, flushing, and throat tightness, have been reported.

• Seizures: Dronabinol has been associated with seizures and seizure-like activity. Assess potential risks versus benefits in patient with a history of seizure disorder, those receiving antiseizure medications, or with other factors that may lower the seizure threshold. Monitor patients with a history of seizure disorder for worsened control. Discontinue dronabinol immediately in patients who develop seizures.

Disease-related concerns:

• Substance abuse: Patients with a history of substance abuse (including marijuana or alcohol abuse) or dependence may be likely to also abuse dronabinol. Assess risk for abuse or misuse prior to treatment and monitor patients with a history of substance abuse throughout treatment. Tolerance, psychological, and physical dependence may occur with prolonged use. EEG changes consistent with withdrawal have been reported upon abrupt dechallenge of dronabinol. Sleep disturbances have been observed for several weeks after discontinuing treatment with high dronabinol doses.

Concurrent drug therapy issues:

• Disulfiram reaction: Dronabinol oral solution contains dehydrated alcohol, which may cause a disulfiram-like reaction (abdominal cramps, nausea, vomiting, headache, and flushing) in patients receiving disulfiram or other medications associated with this reaction (eg, metronidazole). Medications containing disulfiram or metronidazole should be discontinued at least 14 days prior to initiation of dronabinol oral solution and do not administer until 7 days following completion of dronabinol oral solution.

Special populations:

• CYP2C9 polymorphism: Clearance may be reduced and systemic effects increased in patients with CYP2C9 genetic polymorphism. Monitor for increased adverse effects in patients known to carry genetic variants associated with diminished CYP2C9 function.

• Older adult: Because elderly patients may be more sensitive to the neurological, psychoactive, and postural hypotensive effects of dronabinol, use with caution. Consider reduced initial doses. Elderly patients with dementia are already at increased risk for falls and fall risk may be exacerbated with dronabinol; monitor closely.

Other warnings/precautions:

• Propylene glycol: Some dosage forms may contain propylene glycol; large amounts are potentially toxic and have been associated hyperosmolality, lactic acidosis, seizures, and respiratory depression; use caution (AAP 1997; Zar 2007). See manufacturer's labeling.

• Withdrawal: May cause withdrawal symptoms upon abrupt discontinuation.

Warnings: Additional Pediatric Considerations

Syndros oral liquid solution contains 50% (w/w) dehydrated alcohol and 5.5% (w/w) propylene glycol; ethanol competitively inhibits propylene glycol metabolism, which may lead to propylene glycol toxicity in neonates or individuals with impaired elimination. Pediatric patients may be more sensitive to CNS adverse effects.

Some dosage forms may contain propylene glycol; in neonates, large amounts of propylene glycol delivered orally, intravenously (eg, >3,000 mg/day), or topically have been associated with potentially fatal toxicities which can include metabolic acidosis, seizures, renal failure, and CNS depression; toxicities have also been reported in children and adults, including hyperosmolality, lactic acidosis, seizures, and respiratory depression; use caution (AAP 1997; Shehab 2009).

Warfarin: Cannabinoid-Containing Products may increase the serum concentration of Warfarin. Risk C: Monitor therapy

Food Interactions

Capsule: A high-fat (59 g of fat), high-calorie (~950 calories) meal resulted in a 2.9-fold increase in AUC and a 4-hour delay in the median time to peak.

Oral solution: A high-fat meal (59 g of fat) or high-calorie meal (~950 calories) resulted in a 2.5-fold increase in AUC and a 5-hour delay in the median time to peak; food also decreased the Cmax by ~20%.

Pregnancy Considerations

Although information related to the use of synthetic cannabinoids during pregnancy is limited, cannabinoids cross the placenta.

Maternal use of cannabinoids may increase the risk of adverse fetal/neonatal outcomes including growth restriction, low birth weight, preterm birth, and stillbirth. Some dosage forms also contain a significant amount of alcohol, which is also associated with adverse fetal/neonatal outcomes including CNS abnormalities, behavioral disorders, and impaired intellectual development.

Breastfeeding Considerations

Dronabinol is present in breast milk.

According to the manufacturer, when used for chemotherapy-induced nausea and vomiting, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and the benefits of treatment to the mother; breastfeeding should be avoided during treatment and for 9 days after the last dronabinol dose.

The Health and Human Services perinatal HIV guidelines do not recommend breastfeeding for patients in the United States with HIV infection when safer infant feeding options are available (HHS [perinatal] 2021).

Dietary Considerations

Capsules contain sesame oil.

Monitoring Parameters

Monitor heart rate and blood pressure. Monitor for CNS adverse effects, seizures (including worsened seizure control), new or worsening psychiatric symptoms, development of worsening nausea, vomiting or abdominal pain, and substance abuse behavioral profile.

Mechanism of Action

Dronabinol (synthetic delta-9-tetrahydrocannabinol [delta-9-THC]), an active cannabinoid and natural occurring component of Cannabis sativa L. (marijuana), activates cannabinoid receptors CB1 and CB2. Activation of the CB1 receptor produces marijuana-like effects on psyche and circulation, whereas activation of the CB2 receptor does not. Dronabinol has approximately equal affinity for the CB1 and CB2 receptors; however, efficacy is less at CB2 receptors. Activation of the cannabinoid system with dronabinol causes psychological effects that can be divided into 4 groups: affective (euphoria and easy laughter); sensory (increased perception of external stimuli and of the person's own body); somatic (feeling of the body floating or sinking in the bed); and cognitive (distortion of time perception, memory lapses, difficulty in concentration). Most effects (eg, analgesia, appetite enhancement, muscle relaxation, hormonal actions) are mediated by central cannabinoid receptors (CB1), their distribution reflecting many of the medicinal benefits and adverse effects (Grotenhermen 2003).

Pharmacokinetics

Onset of action: ~0.5 to 1 hour

Peak effect: 2 to 4 hours

Duration: 4 to 6 hours (psychoactive effects); ≥24 hours (appetite stimulation)

Absorption: Oral: 90% to 95%; 10% to 20% of dose reaches systemic circulation

Distribution: Vd: ~10 L/kg; dronabinol is highly lipophilic

Protein binding: ~97%

Metabolism: Extensive first-pass hepatic primarily via microsomal hydroxylation to metabolites, some of which are active; 11-hydroxy-delta-9-tetrahydrocannabinol (11-OH-THC) is the major active metabolite

Half-life elimination: Biphasic: Alpha: 4 to 5 hours; Terminal: 25 to 36 hours

Time to peak, serum: 0.5 to 4 hours

Excretion: Feces (50%, <5% as unchanged drug); Urine (10% to 15%)
