Chemotherapy-Induced Nausea & Vomiting
Indicated for nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments
Oral capsules: 5 mg/m² PO 1-3 hr before and q2-4hr after chemotherapy; may be increased in 2.5 mg/m² increments to 15 mg/m²; not to exceed 4-6 doses/day
Oral solution
- Starting dose: 4.2 mg/m² PO 1-3 hr before chemotherapy, THEN q2-4 hr after chemotherapy for a total of 4-6 doses/day
- Give first dose on an empty stomach at least 30 minutes before a meal; subsequent doses can be given without regard to meals
Calculate starting dose
- Starting dose (mg) = Patient body surface area (BSA) in m² multiplied by 4.2 mg/m²
- Round dose to the nearest 0.1 mg increment
- To correspond with the calibrated oral dosing syringe, the dose may need to be rounded to the nearest 0.1 mL increment
Dose titration
- Titrate to clinical response during a chemotherapy cycle or subsequent cycles, based upon initial effect, as tolerated to achieve a clinical effect, in increments of 2.1 mg/m²
- Maximum dosage: 12.6 mg/m² per dose for 4-6 doses/day
- Adverse reactions are dose-related and psychiatric symptoms increase significantly at the maximum dosage
Anorexia
Indicated for anorexia associated with weight loss in patients with AIDS
Oral capsules: 2.5 mg PO q12hr initially, taken right before meals; may be increased to no more than 20 mg/day or decreased to 2.5 mg at bedtime PRN
Oral solution
Starting dose
- 2.1 mg PO BID, 1 hr before lunch and 1 hr before dinner Dosing later in the day may reduce the frequency of CNS adverse reactions
- If CNS adverse reactions of feeling high, dizziness, confusion, and somnolence occur, they usually resolve in 1-3 days and usually do not require dosage reduction
- If CNS adverse reactions are severe or persistent, reduce the dose to 2.1 mg qDay 1 hr before dinner or in the evening at bedtime
Dose titration
- If tolerated and further therapeutic required, increase dose gradually to 2.1 mg 1 hr before lunch and 4.2 mg 1 hr before dinner
- Gradually increase dose to reduce the frequency of dose-related adverse reactions
- Most patients respond to 2.1 mg BID, but the dose may be further increased to 4.2 mg 1 hr before lunch and 4.2 mg 1 hr before dinner, as tolerated to achieve a therapeutic effect
- Maximum dosage: 8.4 mg BID
Dosing Considerations
The pharmacologic effects of dronabinol are dose-related and subject to considerable interpatient variability; dosage individualization is critical in achieving maximum benefit of dronabinol capsules treatment

Warnings
Contraindications
Hypersensitivity to dronabinol
Capsule: Hypersensitivity to sesame seed oil
Oral solution
- History of hypersensitivity reaction to alcohol
- Patients who are receiving, or have received, disulfiram- or metronidazole-containing products within the past 14 days
Cautions
Neurologic effects
- May cause psychiatric and cognitive effects and impair mental and/or physical abilities
- Monitor patients with mania, depression, or schizophrenia; dronabinol may exacerbate these illnesses
- Avoid in patients with a psychiatric history
- Monitor for symptoms and avoid concomitant use of drugs with similar effects (eg, barbiturates, benzodiazepines, lithium, opioids, buspirone, scopolamine, antihistamines, tricyclic antidepressants, other anticholinergic agents, and muscle relaxants), reduce the dose or discontinue use if signs or symptoms of cognitive impairment develop
- Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that dronabinol does not affect them adversely
- Abrupt discontinuation may cause withdrawal symptoms
Hemodynamic instability
- Patients with cardiac disorders may experience hypotension, hypertension, syncope, or tachycardia
- Avoid concomitant use of drugs with similar effects and monitor for hemodynamic changes; monitor patients for changes in blood pressure, heart rate, and syncope after initiating or increasing the dosage (eg, amphetamines, other sympathomimetic agents, atropine, amoxapine, scopolamine, antihistamines, other anticholinergic agents, amitriptyline, desipramine, other tricyclic antidepressants)
- Caution when initiating or increasing the dosage
- Caution in elderly patients; may be more sensitive to neurological, psychoactive, and postural hypotensive effects of drug
Seizures
- Seizures and seizure-like activity reported
- Weigh potential risk before prescribing to patients with a history of seizures, including those with factors that can lower seizure threshold
- If a seizure occurs, discontinue dronabinol immediately
Multiple substance abuse
- Patients with a history of substance abuse or dependence, including marijuana or alcohol, may be more likely to abuse dronabinol
- Assess risk for abuse or misuse before prescribing
Paradoxical nausea, vomiting, or abdominal pain
- New or worsening nausea, vomiting, or abdominal pain can occur during treatment with synthetic delta-9 tetrahydrocannabinol (delta-9-THC), the active ingredient in dronabinol
- In some cases, these adverse reactions were severe (eg, dehydration, electrolyte abnormalities) and required dose reduction or drug discontinuation
- Symptoms are similar to cannabinoid hyperemesis syndrome (CHS), which is described as cyclical events of abdominal pain, nausea, and vomiting in chronic, long-term users of delta-9-THC products
- Patients may not recognize these symptoms as abnormal; specifically monitor for development of worsening nausea, vomiting, or abdominal pain
Toxicities related to propylene glycol in preterm neonates
- Contains the excipients dehydrated alcohol (50%, w/w) and propylene glycol (5.5%, w/w)
- Large amounts of propylene glycol are potentially toxic and have been associated with seizures, lactic acidosis, respiratory depression, and respiratory depression
- When administered concomitantly with propylene glycol, ethanol competitively inhibits the metabolism of propylene glycol, which may lead to elevated concentrations of propylene glycol
- Preterm neonates may be at increased risk of propylene glycol-associated adverse reactions due to a diminished ability to metabolize propylene glycol, thereby, leading to accumulation
- The safety and effectiveness of dronabinol have not been established in pediatric patients
Drug interaction overview
- Coadministration with disulfiram or metronidazole may cause a disulfiramlike reactions (eg, abdominal cramps, nausea, vomiting, headaches, and flushing); discontinue disulfiram or metronidazole at least 14 days before initiating dronabinol and do not administer these products within 7 days of completing treatment with dronabinol
- Inhibitors and inducers of CYP2C9 and CYP3A4: May alter dronabinol systemic exposure; monitor for dronabinol-related adverse reactions or loss of efficacy
- Highly protein-bound drugs: Potential for displacement of other drugs from plasma proteins; monitor for adverse reactions to concomitant narrow therapeutic index drugs (eg, warfarin, cyclosporine, or amphotericin B) when initiating dronabinol or increasing the dosage
- Caution in patients receiving concomitant therapy with sedatives, hypnotics or other psychoactive drugs because of potential for additive or synergistic CNS effects
Caution in pregnant patients, nursing mothers, or pediatric patients; not studied
Pregnancy & Lactation
Pregnancy
May cause fetal harm; avoid use during pregnancy
Published studies suggest that during pregnancy, the use of cannabis, which includes THC, whether for recreational or medicinal purposes, may increase the risk of adverse fetal/neonatal outcomes including fetal growth restriction, low birth weight, preterm birth, small-for-gestational age, admission to the NICU, and stillbirth
Contains alcohol; alcohol is associated with fetal harm including central nervous system abnormalities, behavioral disorders, and impaired intellectual development
Delta-9-THC has been measured in the cord blood of some infants whose mothers reported prenatal use of cannabis, suggesting that dronabinol may cross the placenta to the fetus during pregnancy
Effects of delta-9-THC on the fetus are not known
Animal data
- No teratogenicity reported in mice administered dronabinol (delta-9-THC) at up to 30 times the MRHD (maximum recommended human doses) and up to 5 times the MRHD for patients with AIDS and cancer, respectively
- Decreased maternal weight gain and number of viable pups and increased fetal mortality and early resorptions were observed in both species at doses that induced maternal toxicity
- In rats, maternal administration of dronabinol from pregnancy (implantation) through weaning was associated with maternal toxicity, including mortality of pups, and adverse developmental and neurodevelopmental effects on the pups at 2 to 20 times the MRHD for patients with AIDS and less than and up to 3.3 times the MRHD for patients with cancer
Lactation
Women with HIV: Centers for disease control and prevention recommend that HIV-infected mothers not breastfeed their infants to avoid risking postnatal transmission of HIV
Because of potential for HIV transmission (in HIV-negative infants) and serious adverse reactions in a breastfed infant, instruct mothers not to breastfeed if they are receiving the drug
Women with CINV: There are limited data on presence of drugs in human milk, the effects on breastfed infants, or on milk production; the reported effects of inhaled cannabis transferred to the breastfeeding infant have been inconsistent and insufficient to establish causality
The developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for the drug and any potential adverse effects on breastfed infant from the drug or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Dronabinol is an orally active cannabinoid which has complex effects on the CNS, including central sympathomimetic activity
Cannabinoid receptors have been discovered in neural tissues; these receptors may play a role in mediating the effects of dronabinol
Has appetite stimulant effect
Antiemetic mechanism unknown but probably involves inhibition of vomiting center in medulla oblongata
Absorption
Bioavailability: 90-95%, but due to combined effects of first-pass metabolism and high lipid solubility, only 10-20% of the administered dose reaches systemic circulation
Peak plasma time: 0.5-4 hr (dronabinol and major active metabolite: 11-hydroxy-delta-9-THC)
Peak plasma concentration: 1.9 ng/mL
AUC: 3.8 ng·hr/mL
Distribution
Protein bound: ~97%
Vd: 10 L/kg
Metabolism
Extensive first-pass hepatic metabolism
Metabolites: 11-hydroxy-delta-9-tetrahydrocannabinol (active)
Elimination
Half-life: 5.6 hr (parent drug); 44-59 hr (metabolites)
Renal clearance: 18-20 mL/min
Total body clearance: 0.2 L/kg/hr
Excretion: 50% feces; 15% urine
Pharmacogenomics
Systemic clearance may be reduced and concentrations may be increased in presence of CYP2C9 genetic polymorphism 2- to 3-fold higher dronabinol exposure in individuals carrying genetic variants associated with diminished CYP2C9 function
Monitoring for increased adverse reactions is recommended in patients known to carry genetic variants associated with diminished CYP2C9 function
Administration
Oral Administration
Oral solution
- Always use the enclosed calibrated oral dosing syringe when administering to ensure the dose is measured and administered accurately
- The calibrated oral syringe measures a maximum dronabinol dose of 5 mg; if the prescribed dose exceeds 5 mg, the total dose will need to be divided and drawn up in 2 or more portions using the oral syringe
- Take each dose with a full glass of water (6-8 oz)
Meals
- CINV: Take first dose on an empty stomach at least 30 minutes before eating; subsequent doses can be taken without regard to meals
- Anorexia: Take BID 1 hr before lunch and dinner
