Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE SYNDROS is indicated in adults for the treatment of: anorexia associated with weight loss in patients with Acquired Immune Deficiency Syndrome (AIDS). nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments. SYNDROS is a cannabinoid indicated in adults for the treatment of: anorexia associated with weight loss in patients with AIDS. ( 1 ) nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments.
( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Administration ( 2.1 ): Always use the enclosed calibrated oral dosing syringe. The calibrated oral syringe measures a maximum SYNDROS dose of 5 mg. If the prescribed dose is greater than 5 mg, the total dose will need to be divided and drawn up in two or more portions using the oral syringe.
Take SYNDROS with a full glass of water (6 to 8 ounces). SYNDROS can be administered via silicone enteral feeding tubes. Anorexia Associated with Weight Loss in Adult Patients with AIDS ( 2.2 ): The recommended starting dosage is 2.1 mg orally twice daily, one hour before lunch and dinner.
See the full prescribing information for dosage titration to manage adverse reactions and to achieve desired therapeutic effect. Nausea and Vomiting Associated with Chemotherapy in Adult Patients Who Failed Conventional Antiemetics ( 2.3 ): The recommended starting dosage is 4.2 mg/m 2 , administered 1 to 3 hours prior to chemotherapy, then every 2 to 4 hours after chemotherapy for a total of 4 to 6 doses per day. Administer the first dose on an empty stomach at least 30 minutes prior to eating; subsequent doses can be taken without regard to meals.
See the full prescribing information for dosage titration to manage adverse reactions and to achieve desired therapeutic effect.
2.1Important Administration Instructions Oral Administration Always use the enclosed calibrated oral dosing syringe when administering SYNDROS to ensure the dose is measured and administered accurately. The calibrated oral syringe measures a maximum SYNDROS dose of 5 mg. If the prescribed dose is greater than 5 mg, the total dose will need to be divided and drawn up in two or more portions using the oral syringe.
Take each dose of SYNDROS with a full glass of water (6 to 8 ounces). For information on dosing SYNDROS with regard to meals, see Dosage and Administration 2.2 and 2.3 . Administration via Feeding Tube (silicone only, greater than or equal to 14 French) SYNDROS can be administered via enteral feeding tubes that are manufactured using silicone, size greater than or equal to 14 French, such as Naso-Gastric (NG), Gastrostomy Tube (G-tube), Percutaneous Endoscopic Gastrostomy tube (PEG-tube) and Gastro-Jejunostomy tube (GJ-tube).
Do not use tubes manufactured of polyurethane. Draw up the prescribed dose with the calibrated dosing syringe packaged with SYNDROS. If the prescribed dose is greater than 5 mg, the total dose will need to be divided and drawn up in two or more portions using the oral syringe.
Using the calibrated dosing syringe, administer the dose via the feeding tube. Using a catheter-tip syringe, flush the feeding tube with 30 mL of water.
2.2Anorexia Associated with Weight Loss in Adult Patients with AIDS Starting Dosage The recommended adult starting dosage of SYNDROS is 2.1 mg orally twice daily, one hour before lunch and one hour before dinner. In elderly patients, or patients unable to tolerate 2.1 mg twice daily, consider initiating SYNDROS at 2.1 mg once daily one hour before dinner or at bedtime to reduce the risk of central nervous system (CNS) symptoms [see Use in Specific Populations ( 8.5 ) ]. Dosing later in the day may reduce the frequency of Central Nervous System (CNS) adverse reactions.
CNS adverse reactions are dose-related [see Warnings and Precautions ( 5.1 )] ; therefore, monitor patients and reduce the dosage as needed. If CNS adverse reactions of feeling high, dizziness, confusion, and somnolence occur, they usually resolve in 1 to 3 days and usually do not require dosage reduction. If CNS adverse reactions are severe or persistent, reduce the dosage to 2.1 mg once daily one hour before dinner or in the evening at bedtime.
Dosage Titration If tolerated and further therapeutic effect is desired, the dosage may be increased gradually to 2.1 mg one hour before lunch and 4.2 mg one hour before dinner. Increase the dose of SYNDROS gradually in order to reduce the frequency of dose-related adverse reactions [see Warni… [Excerpted — this section continues on DailyMed.]

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Neuropsychiatric Adverse Reactions : May cause psychiatric and cognitive effects and impair mental and/or physical abilities. Avoid use in patients with a psychiatric history. Monitor for symptoms and avoid concomitant use of drugs with similar effects.
Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that SYNDROS does not affect them adversely. ( 5.1 ) 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 after initiating or increasing the dosage of SYNDROS.
( 5.2 ) Interaction with Disulfiram and Metronidazole : May cause disulfiram-like reaction. Discontinue products containing disulfiram or metronidazole at least 14 days before and do not administer 7 days after treatment with SYNDROS. ( 4 , 5.3 , 7.1 ) Seizures and Seizure-like Activity : Weigh the potential risk versus benefits before prescribing SYNDROS to patients with a history of seizures, including those requiring anti-epileptic medication or with other factors that lower the seizure threshold.
Monitor patients and discontinue if seizures occur. ( 5.4 ) Multiple Substance Abuse : Assess risk for abuse or misuse in patients with a history of substance abuse or dependence, prior to prescribing SYNDROS and monitor for the development of associated behaviors or conditions. ( 5.5 ) Paradoxical Nausea, Vomiting, or Abdominal Pain : Consider dose reduction or discontinuation, if worsening of symptoms while on treatment.
( 5.6 ) Toxicities Related to Propylene Glycol in Preterm Neonates : The safety and effectiveness of SYNDROS have not been established in pediatric patients. Avoid use in preterm neonates in the immediate postnatal period. ( 5.7 )
5.1Neuropsychiatric Adverse Reactions Psychiatric Adverse Reactions Dronabinol has been reported to exacerbate mania, depression, or schizophrenia. Prior to initiating treatment with SYNDROS, screen patients for a history of these illnesses. Avoid use in patients with a psychiatric history or, if the drug cannot be avoided, monitor patients for new or worsening psychiatric symptoms during treatment.
Also, avoid concomitant use with other drugs that are associated with similar psychiatric effects. Cognitive Adverse Reactions Use of SYNDROS has been associated with cognitive impairment and altered mental state. Reduce the dose of SYNDROS or discontinue use of SYNDROS if signs or symptoms of cognitive impairment develop.
Elderly and pediatric patients may be more sensitive to the neurological and psychoactive effects of SYNDROS [see Use in Specific Populations ( 8.4 , 8.5 )] . Hazardous Activities SYNDROS can cause and may impair the mental and/or physical abilities required for the performance of hazardous tasks such as driving a motor vehicle or operating machinery. Concomitant use of other drugs that cause dizziness, confusion, sedation, or somnolence such as CNS depressants may increase this effect (e.g., barbiturates, benzodiazepines, lithium, opioids, buspirone, scopolamine, antihistamines, tricyclic antidepressants, other anticholinergic agents, and muscle relaxants).
Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that SYNDROS does not affect them adversely.
5.2Hemodynamic Instability Patients may experience occasional hypotension, possible hypertension, syncope, or tachycardia while taking SYNDROS [see Clinical Pharmacology ( 12.2 )] . Patients with cardiac disorders may be at higher risk. Avoid concomitant use of other drugs that are also associated with similar cardiac effects (e.g., amphetamines, other sympathomimetic agents, atropine, amoxapine, scopolamine, antihistamines, other anticholinergic agents, amitriptyline, desipramine, other tricyclic antidepressants).
Monitor patients for changes in blood pressure, heart… [Excerpted — this section continues on DailyMed.]
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Most common adverse reactions (≥3%) are: abdominal pain, dizziness, euphoria, nausea, paranoid reaction, somnolence, thinking abnormal, and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Benuvia Operations, LLC at 1-844-558-8289 or FDA at MedWatch phone number 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The following serious adverse reactions are described below and elsewhere in the labeling. Neuropsychiatric Adverse Reactions [see Warnings and Precautions ( 5.1 )] Hemodynamic Instability [see Warnings and Precautions ( 5.2 )] Seizures [see Warnings and Precautions ( 5.4 )] Paradoxical Nausea, Vomiting, and Abdominal Pain [see Warnings and Precautions ( 5.6 )] Toxicity in Preterm Neonates [see Warnings and Precautions ( 5.7 )] The safety of SYNDROS has been established based on studies of dronabinol capsules.
Studies of AIDS-related weight loss included 157 patients receiving dronabinol capsules and 67 receiving placebo. Studies of nausea and vomiting related to cancer chemotherapy included 317 patients receiving dronabinol capsules and 68 receiving placebo. In the tables below is a summary of the adverse reactions in 474 patients exposed to dronabinol capsules in studies.
Studies of different durations were combined by considering the first occurrence of adverse reactions during the first 28 days. A cannabinoid dose-related “high” (easy laughing, elation and heightened awareness) has been reported by patients receiving dronabinol capsules in both the antiemetic (24%) and the lower dose appetite stimulant clinical trials (8%). The most frequently reported adverse experiences in patients with AIDS during placebo-controlled clinical trials involved the CNS and were reported by 33% of patients receiving dronabinol capsules.
About 25% of patients reported a CNS adverse reaction during the first 2 weeks and about 4% reported such a reaction each week for the next 6 weeks thereafter. Common Adverse Reactions The following adverse reactions were reported in clinical trials of dronabinol capsules at an incidence greater than 1%. *Actual Incidence 3% to 10% System Organ Class Adverse Reactions General Asthenia Cardiovascular Palpitations, tachycardia, vasodilation/facial flush Gastrointestinal Abdominal pain*, nausea*, vomiting* Central Nervous System Dizziness*, euphoria*, paranoid reaction*, somnolence*, thinking abnormal*, amnesia, anxiety/nervousness, ataxia, confusion, depersonalization, hallucination Less Common Adverse Reactions The following adverse reactions were reported in clinical trials of dronabinol capsules at an incidence less than or equal to 1%.
System Organ Class Adverse Reactions General Chills, headache, malaise Cardiovascular Hypotension, conjunctival injection [see Clinical Pharmacology ( 12.2 )] Gastrointestinal Diarrhea, fecal incontinence, anorexia, hepatic enzyme elevation Musculoskeletal Myalgias Central Nervous System Depression, nightmares, speech difficulties, tinnitus Respiratory Cough, rhinitis, sinusitis Skin Flushing, sweating Sensory Vision difficulties
6.2Postmarketing Experience The following adverse reactions have been identified during post-approval use of another oral formulation of dronabinol. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. General disorders and administration site conditions: fatigue.
Hypersensitivity reactions : lip swelling, hives, disseminated rash, oral lesions, skin burning, flushing, throat tightness [see Contraindications ( 4 )] . Injury, poisoning and procedural complications : fall [see Use i… [Excerpted — this section continues on DailyMed.]
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Inhibitors and Inducers of CYP2C9 and CYP3A4 : May alter dronabinol systemic exposure; monitor for dronabinol-related adverse reactions or loss of efficacy. ( 7.2 ) Highly Protein-Bound Drugs : Potential for displacement of other drugs from plasma proteins; monitor for adverse reactions to concomitant narrow therapeutic index drugs (e.g., warfarin, cyclosporine, or amphotericin B) when initiating or increasing the dosage of SYNDROS. ( 7.3 )
7.1Disulfiram and Metronidazole SYNDROS contains 50% (w/w) dehydrated alcohol and 5.5% (w/w) propylene glycol, which can produce disulfiram-like reactions when co-administered with disulfiram or other drugs that produce this reaction (e.g., metronidazole). Discontinue products containing disulfiram or metronidazole at least 14 days before starting treatment with SYNDROS and do not administer these products within 7 days of completing treatment with SYNDROS [see Contraindications ( 4 ), Warnings and Precautions ( 5.3 )] .
When administered concomitantly with propylene glycol, ethanol competitively inhibits the metabolism of propylene glycol, which may lead to elevated concentrations of propylene glycol. However, the contribution of propylene glycol, if any, to the interaction between disulfiram and SYNDROS is unknown.
7.2Effect of Other Drugs on Dronabinol Dronabinol is primarily metabolized by CYP2C9 and CYP3A4 enzymes. Inhibitors of these enzymes may increase, while inducers may decrease, the systemic exposure of dronabinol and/or its active metabolite resulting in an increase in dronabinol-related adverse reactions or loss of efficacy of SYNDROS. Monitor for increased dronabinol-related adverse reactions when SYNDROS is co-administered with inhibitors of CYP2C9 (e.g., amiodarone, fluconazole) and inhibitors of CYP3A4 enzymes (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, erythromycin, grapefruit juice).
7.3Highly Protein-Bound Drugs Dronabinol is highly bound to plasma proteins, and therefore, might displace and increase the free fraction of other concomitantly administered protein-bound drugs. Although this displacement has not been confirmed in vivo, monitor patients for increased adverse reactions to narrow therapeutic index drugs (e.g., warfarin, cyclosporine, amphotericin B) when initiating treatment or increasing the dosage of SYNDROS.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy : May cause fetal harm. ( 8.1 ) Lactation : Advise HIV infected women not to breastfeed due to the potential for HIV transmission. ( 8.2 ) Geriatric Use: Elderly patients may be more sensitive to the neuropsychiatric and postural hypotensive effects. Consider a lower starting dose in elderly patients. ( 2.2 , 2.3 , 5.1 , 5.2 , 8.5 )
8.1Pregnancy Risk Summary SYNDROS, a synthetic cannabinoid containing alcohol, may cause fetal harm. Avoid use of SYNDROS in pregnant women. Although there is little published data on the use of synthetic cannabinoids during pregnancy, use of cannabis (e.g., marijuana) and use of alcohol during pregnancy have been associated with adverse fetal/neonatal outcomes (see Clinical Considerations ) .
Cannabinoids have been found in the umbilical cord blood from pregnant women who smoke cannabis. In animal reproduction studies, no teratogenicity was 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. Similar findings were reported in pregnant rats administered dronabinol at up to 5 to 20 times the MRHD and 3 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 which 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.
(see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions 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 neonatal intensive care unit, and stillbirth.
Therefore, use of cannabis during pregnancy should be avoided. SYNDROS contains alcohol. Published studies have demonstrated that alcohol is associated with fetal harm including central nervous system abnormalities, behavioral disorders, and impaired intellectual development.
Avoid use of SYNDROS in pregnant women. Data Human Data 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. The effects of delta-9-THC on the fetus are not known.
Animal Data The recommended dose ranges for SYNDROS in patients with AIDS and patients with cancer are designed to achieve the same systemic exposure ranges to delta-9-THC as with the recommended dose ranges for dronabinol capsules. Therefore, animal to human dose multiples, as shown below, are based on the MRHDs (maximum recommended human doses) for dronabinol capsules, instead of the MRHDs for SYNDROS, which are 15% lower. This approach for dose comparison between animals and humans is supported by the demonstrated difference in dronabinol bioavailability between SYNDROS and dronabinol capsules.
Reproduction studies with dronabinol have been performed in mice at 15 to 450 mg/m 2 , equivalent to 1 to 30 times the MRHD of 15 mg/m 2 /day (dronabinol capsules) in patients with AIDS or 0… [Excerpted — this section continues on DailyMed.]

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of SYNDROS have not been established in pediatric patients. Pediatric patients may be more sensitive to neurological and psychoactive effects of SYNDROS [see Warnings and Precautions ( 5.1 )] . SYNDROS contains the excipients 50% (w/w) dehydrated alcohol and 5.5% (w/w) 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 events due to diminished ability to metabolize propylene glycol, thereby, leading to accumulation [see Warnings and Precautions ( 5.7 )] .
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of dronabinol capsules in AIDS and cancer patients did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Elderly patients may be more sensitive to the neuropsychiatric and postural hypotensive effects of SYNDROS [see Warnings and Precautions ( 5.1 , 5.2 )] . Elderly patients with dementia are at increased risk for falls as a result of their underlying disease state, which may be exacerbated by the CNS effects of somnolence and dizziness associated with SYNDROS [see Warnings and Precautions ( 5.1 )] .
These patients should be monitored closely and placed on fall precautions prior to initiating SYNDROS therapy. In antiemetic studies, no difference in efficacy was apparent in patients greater than 55 years of age compared to younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of falls, decreased hepatic, renal, or cardiac function, increased sensitivity to psychoactive effects, and of concomitant disease or other drug therapy [see Dosage and Administration ( 2.2 , 2.3 )] .
🆘 Overdosage ▾
10 OVERDOSAGE SYNDROS contains 50% (w/w) dehydrated alcohol and 5.5% (w/w) propylene glycol. Ingestion of the product over the recommended dose could result in significant toxicity. Dronabinol Signs and symptoms of dronabinol overdose include drowsiness, euphoria, heightened sensory awareness, altered time perception, reddened conjunctiva, dry mouth, tachycardia, memory impairment, depersonalization, mood alteration, urinary retention, reduced bowel motility, decreased motor coordination, lethargy, slurred speech, and postural hypotension.
Patients may also experience panic reactions if they have a prior history of nervousness or anxiety and seizures may occur in patients with existing seizure disorders. It is not known if dronabinol can be removed by dialysis in cases of overdose. Alcohol Signs and symptoms of alcohol overdose include changes in mood or behavior, impaired judgment or social functioning, and one or more physical signs such as slurred speech, unsteadiness, lack of coordination, increased or irregular heart rate, respiratory depression, impaired attention, or loss of consciousness.
Propylene Glycol Signs and symptoms of acute poisoning occur only in rare circumstances where patients ingest large amounts of propylene glycol over several days. These include hypoglycemia, severe metabolic acidosis (caused by the metabolism into lactic acid), and CNS depression including coma and seizures. Management of Overdosage If over-exposure of SYNDROS occurs, call your Poison Control Center at 1-800-222-1222 for current information on the management of poisoning or overdosage.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Dronabinol is an orally active cannabinoid that 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.
12.2Pharmacodynamics Effects on the Cardiovascular System Dronabinol-induced sympathomimetic activity may result in tachycardia and/or conjunctival injection. Its effects on blood pressure are inconsistent, but subjects have experienced orthostatic hypotension and/or syncope upon abrupt standing [see Warnings and Precautions ( 5.2 )] . Effects on the Central Nervous System Dronabinol also demonstrates reversible effects on appetite, mood, cognition, memory, and perception.
These phenomena appear to be dose-related, increasing in frequency with higher dosages, and subject to great inter-patient variability. After oral administration, dronabinol capsules have an onset of action of approximately 0.5 to 1 hours and peak effect at 2 to 4 hours. Duration of action for psychoactive effects is 4 to 6 hours, but the appetite stimulant effect of dronabinol may continue for 24 hours or longer after administration.
Tachyphylaxis and tolerance develop to some of the cardiovascular and CNS pharmacologic effects of dronabinol with chronic use, suggesting an indirect effect on sympathetic neurons. In a study of the pharmacodynamics of chronic dronabinol exposure, healthy male subjects (N = 12) received 12 times the maximum dose for anorexia associated with weight loss in patients with AIDS of dronabinol capsules in divided doses for 16 days. An initial tachycardia induced by dronabinol was replaced successively by normal sinus rhythm and then bradycardia.
A decrease in supine blood pressure, made worse by standing, was also observed initially. These subjects developed tolerance to the cardiovascular and subjective adverse CNS effects of dronabinol within 12 days of treatment initiation. Tachyphylaxis and tolerance do not appear to develop to the appetite stimulant effect of dronabinol.
In clinical studies of dronabinol capsules in AIDS patients, at the recommended dosage, the appetite stimulant effect was sustained for up to five months.
12.3Pharmacokinetics Absorption Dronabinol (delta-9-THC) is almost completely absorbed (90 to 95%) after a single oral dose. 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. Relative bioavailability data from healthy male and female subjects suggest that a dose of 4.2 mg of SYNDROS provides comparable systemic exposure (C max and AUC) to a 5 mg dronabinol capsule, under fasted conditions [see Dosage and Administration ( 2.1 )] .
The concentrations of both dronabinol and its major active metabolite (11-hydroxy-delta-9-THC) peak at approximately 0.5 to 4 hours after oral dosing with SYNDROS and decline over several days. The mean inter- and intra-subject variability in dronabinol pharmacokinetics (C max and AUC inf ) was approximately 66% and 47% and 67% and 14%, respectively, following administration of SYNDROS to healthy subjects.

2.7Food Effect The effect of food on the pharmacokinetics of SYNDROS was studied by concomitant dosing of SYNDROS with a high-fat (59 grams of fat, approximately 50% of total caloric content of the meal), high calorie meal (approximately 950 calories). An appreciable food effect was observed: food resulted in approximately a 2.5-fold increase in total exposure (AUC inf ) and approximately a 5 hour delay in median T max . Food also decreased C max by approximately 20% [see Dosage and Administration ( 2.2 , 2.3 )] .
Distribution Dronabinol has an apparent volume of distribution of approximately 10 L/kg, because of its lipid solubility. The plasma protein binding of dronabinol and its metabolites is approximately 97% [see Drug Interactions ( 7.3 )] . Elimination The pharmacokinetics of dronabinol can be described using a two compartment model with an initial (alpha) half-life of about 5 hours and a terminal (beta) half-life of 25 to 36 hours.
Values for clearance average about
0.2L/kg-hr; but are highly variable due to the complexity of cannabinoid distribution. Metabolism Dronabinol undergoes extensive first-pass hepatic metabolism, primarily by hydroxylation, yielding both active and inactive metabolites. The major metabolite (11-hydroxy-delta-9-THC) is pharmacologically active.
Published in vitro data indicate that CYP2C9 and CYP3A4 are the primary enzymes in the metabolism of dronabinol. CYP2C9 appears to be the enzyme responsible for the formation of the primary active metabolite [see Clinical Pharmacology ( 12.5 )] . Excretion Dronabinol and its biotransformation products are excreted in both feces and urine.
Biliary excretion is the major route of excretion with about half of a radio-labeled oral dose being recovered from the feces within 72 hours as contrasted with 10 to 15% recovered from urine. Less than 5% of an oral dose is recovered unchanged in the feces. Due to its re-distribution, dronabinol and its metabolites may be excreted for prolonged periods of time.
Following single dose administration, dronabinol metabolites have been detected for more than 5 weeks in the urine and feces. In a study of dronabinol capsules involving AIDS patients, urinary cannabinoid/creatinine concentration ratios were studied bi-weekly over a six week period. The urinary cannabinoid/creatinine ratio was closely correlated with dose.
No increase in the cannabinoid/creatinine ratio was observed after the first two weeks of treatment, indicating that steady-state cannabinoid levels had been reached. This conclusion is consistent with predictions based on the observed terminal half-life of dronabinol. Drug Interaction Studie… [Excerpted — this section continues on DailyMed.]

🔬 Clinical Studies ▾
14 CLINICAL STUDIES The effectiveness of SYNDROS has been established based on studies of dronabinol capsules for the treatment of anorexia associated with weight loss in patients with AIDS and nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments.
🔒 Drug Abuse and Dependence ▾
9 DRUG ABUSE AND DEPENDENCE
9.1Controlled Substance SYNDROS contains dronabinol oral solution, a Schedule II controlled substance.
9.2Abuse SYNDROS contains dronabinol, the main psychoactive component in marijuana. Ingestion of high doses of dronabinol increases the risk of psychiatric adverse reactions if abused or misused, while continued administration can lead to addiction. Psychiatric adverse reactions may include psychosis, hallucinations, depersonalization, mood alteration, and paranoia.
In vitro studies demonstrate that SYNDROS can be easily and effectively abused without manipulation. SYNDROS contains 50% (w/w) dehydrated alcohol [see Warning and Precautions ( 5.5 )] . In a randomized, single-dose, double-blind, placebo- and active-controlled crossover pharmacodynamic study of 43 experienced marijuana smokers, “drug liking” responses and safety of SYNDROS were compared with placebo and dronabinol in sesame oil oral capsules.
Treatment arms were 10 mg and 30 mg dronabinol capsules, 10 mg and 30 mg dronabinol from SYNDROS, and placebo oral solution and capsules. Greater “drug liking” scores were reported with the 30 mg dose, compared with the 10 mg dose, for both SYNDROS and dronabinol-containing capsules. Overall, the pharmacodynamic results from this study demonstrated no statistically significant differences in various measures of drug liking for the doses taken, though the SYNDROS results were consistently greater than those of dronabinol capsules.
Similarly, observed adverse reactions were greater for SYNDROS. The pharmacodynamic and safety effects of SYNDROS following multiple doses have not been evaluated. Patients should be instructed to keep SYNDROS in a secure place out of reach of others for whom the medication has not been prescribed.
9.3Dependence Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use. Physical dependence manifests by drug class-specific withdrawal symptoms after abrupt discontinuation or a significant dose reduction of a drug. The appearance of a withdrawal syndrome when administration of the drug is terminated is the only actual evidence of physical dependence.
Physical dependence can develop during chronic therapy with SYNDROS and develops after chronic abuse of marijuana. A withdrawal syndrome was reported after the abrupt discontinuation of dronabinol capsules in subjects receiving dosages of 210 mg per day for 12 to 16 consecutive days. Within 12 hours after discontinuation, subjects manifested symptoms such as irritability, insomnia, and restlessness.
By approximately 24 hours post-dronabinol discontinuation, withdrawal symptoms intensified to include “hot flashes”, sweating, rhinorrhea, loose stools, hiccoughs, and anorexia. These withdrawal symptoms gradually dissipated over the next 48 hours. Electroencephalographic changes consistent with the effects of drug withdrawal (hyperexcitation) were recorded in patients after abrupt dechallenge.
Patients also complained of disturbed sleep for several weeks after discontinuing therapy with high dosages of dronabinol.

13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility The recommended dose ranges for SYNDROS in AIDS and cancer patients are designed to achieve the same systemic exposure ranges as with the recommended dose ranges for dronabinol capsules. Therefore, the animal to human dose multiples for carcinogenicity studies, as shown below, are based on the MRHD (maximum recommended human dose) for dronabinol capsules in AIDS patients, instead of the MRHD for SYNDROS which is 15% lower. This approach for dose comparison between animals and humans is supported by the demonstrated difference in dronabinol bioavailability between SYNDROS and dronabinol capsules.
The animal to human dose multiples for the fertility study in rats, as shown below, are based on the MRHD for dronabinol capsules in AIDS or cancer patients. In 2-year carcinogenicity studies, there was no evidence of carcinogenicity in rats at doses up to 50 mg/kg/day dronabinol (approximately 20 times the MRHD for dronabinol capsules in AIDS patients on a body surface area basis) or in mice at doses up to 500 mg/kg/day (approximately 100 times the MRHD for dronabinol capsules in AIDS patients on a body surface area basis).
Dronabinol was not genotoxic in the Ames tests, the in vitro chromosomal aberration test in Chinese hamster ovary cells, and the in vivo mouse micronucleus test. However, dronabinol produced a weak positive response in a sister chromatid exchange test in Chinese hamster ovary cells. In a long-term study (77 days) in rats, oral administration of dronabinol at doses of 30 to 150 mg/m 2 , equivalent to 2 to 10 times the MRHD of 15 mg/m 2 /day (dronabinol capsules) in AIDS patients or 0.3 to 1.5 times the MRHD of 90 mg/m 2 /day (dronabinol capsules) in cancer patients, reduced ventral prostate, seminal vesicle and epididymal weights and caused a decrease in seminal fluid volume.
Decreases in spermatogenesis, number of developing germ cells, and number of Leydig cells in the testis were also observed. However, sperm count, mating success and testosterone levels were not affected. The significance of these animal findings in humans is not known.
