Clinical
Clonidine is used alone or in combination with other medications to treat high blood pressure. Clonidine is also used alone or in combination with other medications as part of a treatment program to control symptoms of attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age) in children 6 years of age and older. Clonidine is in a class of medications called centrally acting alpha-agonist hypotensive agents. Clonidine treats high blood pressure by decreasing your heart rate and relaxing th...

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 ONYDA XR is indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) as monotherapy and as adjunctive therapy to central nervous system (CNS) stimulant medications in pediatric patients 6 years of age and older [see Clinical Studies ( 14 )]. ONYDA XR is a centrally acting alpha 2 -adrenergic agonist indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) as monotherapy or as adjunctive therapy to central nervous system (CNS) stimulant medications in pediatric patients 6 years of age and older.
( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Starting dosage is 0.1 mg of ONYDA XR orally once daily at bedtime with or without food. Dosage may be increased in increments of 0.1 mg per day at weekly intervals. Maximum recommended dosage is 0.4 mg once daily at bedtime.
( 2.1 ) Do not substitute ONYDA XR for other clonidine products on a mg-per-mg basis because of differing pharmacokinetic profiles. ( 2.3 ) When discontinuing, taper the dose in decrements of no more than 0.1 mg every 3 to 7 days to avoid rebound hypertension. ( 2.4 )
2.1Recommended Dosage The starting dosage of ONYDA XR is 0.1 mg orally once daily at bedtime with or without food [see Clinical Pharmacology ( 12.3 )] . Titrate the dose of ONYDA XR in increments of 0.1 mg per day at weekly intervals depending on clinical response up to the maximum recommended dosage of 0.4 mg once daily at bedtime. Doses of ONYDA XR higher than 0.4 mg once daily were not evaluated in clinical trials for ADHD and are not recommended.
When ONYDA XR is added to a CNS stimulant, adjust the dose of the CNS stimulant depending on the clinical response to ONYDA XR.
2.2Administration Instructions Instruct patients to read the “Instructions for Use” for complete administration instructions. Use the oral dosing dispenser and bottle adapter provided with ONYDA XR. Ensure that the bottle adapter is firmly inserted into the bottle before first use and keep the adapter in place for the duration of the usage of the bottle.
Gently shake ONYDA XR with a smooth up and down motion (to avoid foaming) for at least 10 seconds before each administration. For the bottles of 30 mL and 60 mL, discard any unused ONYDA XR 30 days after first opening the bottle. For the 120 mL bottle, discard any unused ONYDA XR 60 days after first opening the bottle.
2.3Switching from Other Clonidine Products For patients switching from another clonidine product, discontinue that treatment, and titrate with ONYDA XR using the titration schedule [see Dosage and Administration ( 2.1 )] . Do not substitute for other clonidine products on a milligram-per-milligram basis because of differing pharmacokinetic profiles [see Clinical Pharmacology ( 12.3 )].
2.4Discontinuation When discontinuing ONYDA XR, taper the total daily dose in decrements of no more than 0.1 mg every 3 to 7 days to avoid rebound hypertension [see Warnings and Precautions ( 5.3 )].
2.5Missed Doses If a dose of ONYDA XR is missed, skip that dose and take the next dose as scheduled. Do not take more than the prescribed total daily amount of ONYDA XR in any 24-hour period.
💊 Dosage Forms and Strengths ▾
3 DOSAGE FORMS AND STRENGTHS Extended-release oral suspension: Light beige to tan viscous suspension containing 0.1 mg clonidine hydrochloride per mL. Extended-release oral suspension: 0.1 mg clonidine hydrochloride per mL ( 3 )
⛔ Contraindications ▾
4 CONTRAINDICATIONS ONYDA XR is contraindicated in patients with a history of a hypersensitivity reaction to clonidine. Reactions have included generalized rash, urticaria, and angioedema [see Warnings and Precautions ( 5.4 ) and Adverse Reactions ( 6 )]. History of a hypersensitivity reaction to clonidine. Reactions have included generalized rash, urticaria, angioedema. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypotension/bradycardia: Titrate slowly and monitor vital signs frequently in patients at risk for hypotension, heart block, bradycardia, syncope, cardiovascular disease, vascular disease, cerebrovascular disease, or chronic renal failure. Measure heart rate and blood pressure prior to initiation of therapy, following dose increases, and periodically while on therapy. Avoid concomitant use of drugs with additive effects unless clinically indicated.
Advise patients to avoid becoming dehydrated or overheated. ( 5.1 ) Somnolence/Sedation: Has been observed with clonidine. Consider the potential for additive sedative effects with CNS depressant drugs.
Caution patients against operating heavy equipment or driving until they know how they respond to ONYDA XR ( 5.2 ) Cardiac Conduction Abnormalities: May worsen sinus node dysfunction and atrioventricular (AV) block, especially in patients taking other sympatholytic drugs. Titrate slowly and monitor vital signs frequently. ( 5.5 )
5.1Hypotension/Bradycardia Treatment with ONYDA XR can cause dose-related decreases in blood pressure and heart rate [see Adverse Reactions ( 6.1 )]. Measure heart rate and blood pressure prior to initiation of therapy, following dose increases, and periodically while on therapy. Titrate ONYDA XR slowly in patients with a history of hypotension, and those with underlying conditions that may be worsened by hypotension and bradycardia; e.g., heart block, bradycardia, cardiovascular disease, vascular disease, cerebrovascular disease, or chronic renal failure.
In patients who have a history of syncope or may have a condition that predisposes them to syncope, such as hypotension, orthostatic hypotension, bradycardia, or dehydration, advise patients to avoid becoming dehydrated or overheated. Monitor blood pressure and heart rate, and adjust dosages accordingly in patients treated concomitantly with antihypertensives or other drugs that can reduce blood pressure or heart rate or increase the risk of syncope [see Drug Interactions ( 7 )] .
5.2Sedation and Somnolence Somnolence and sedation were commonly reported adverse reactions in clinical studies with clonidine hydrochloride extended-release tablets. In patients that completed 5 weeks of therapy in a controlled, fixed dose pediatric monotherapy study, 31% of patients treated with 0.4 mg/day and 38% treated with 0.2 mg/day versus 4% of placebo treated patients reported somnolence as an adverse reaction. In patients that completed 5 weeks of therapy in a controlled flexible dose pediatric adjunctive to stimulants study, 19% of patients treated with clonidine hydrochloride extended-release tablets plus a stimulant versus 7% treated with placebo plus a stimulant reported somnolence.
Before using ONYDA XR with other centrally active depressants (such as phenothiazines, barbiturates, or benzodiazepines), consider the potential for additive sedative effects [see Drug Interactions ( 7 )] . Caution patients against operating heavy equipment or driving until they know how they respond to treatment with ONYDA XR. Advise patients to avoid use with alcohol.
5.3Rebound Hypertension Abrupt discontinuation of ONYDA XR can cause rebound hypertension. In adults with hypertension, sudden cessation of clonidine extended-release formulation treatment in the 0.2 to 0.6 mg per day range resulted in reports of headache, tachycardia, nausea, flushing, warm feeling, brief lightheadedness, tightness in chest, and anxiety. In adults with hypertension, sudden cessation of treatment with immediate-release clonidine has, in some cases, resulted in symptoms such as nervousness, agitation, headache, and tremor accompanied or followed by a rapid rise in blood pressure and elevated catecholamine concentrations in the plasma.
Pediatric patients with gastrointestinal illnesses that lead to vomiting may result in missed doses of ONYDA XR, increasing the risk for rebound hypertension. No studies evaluating abrupt discont… [Excerpted — this section continues on DailyMed.]

6 ADVERSE REACTIONS The following serious adverse reactions are described in greater detail elsewhere in labeling: Hypotension/bradycardia [see Warnings and Precautions ( 5.1 )] Sedation and somnolence [see Warnings and Precautions ( 5.2 )] Rebound hypertension [see Warnings and Precautions ( 5.3 )] Allergic reactions [see Warnings and Precautions ( 5.4 )] Cardiac Conduction Abnormalities [see Warnings and Precautions ( 5.5 )] Most common adverse reactions (incidence at least 5% and twice the rate of placebo) as monotherapy in ADHD: somnolence, fatigue, irritability, nightmare, insomnia, constipation, dry mouth.
( 6.1 ) Most common adverse reactions (incidence at least 5% and twice the rate of placebo) as adjunct therapy to psychostimulant in ADHD: somnolence, fatigue, decreased appetite, dizziness. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Tris Pharma, Inc. at (732) 940-0358 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trial 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 safety of ONYDA XR for the treatment of ADHD in pediatric patients 6 years and older is based upon adequate and well-controlled studies of clonidine hydrochloride extended-release tablets (referred to as “clonidine hydrochloride extended-release” in this section).
The safety results of these adequate and well-controlled studies of clonidine hydrochloride extended-release tablets are presented below. Two clonidine hydrochloride extended-release ADHD clinical studies (Study 1 and Study 2) evaluated 256 patients in two 8-week placebo-controlled studies. A third clonidine hydrochloride extended-release ADHD clinical study (Study 3) evaluated 135 pediatric patients 6 to 17 years of age in a 40-week placebo-controlled randomized‑withdrawal study.
Study 1: Fixed-dose clonidine hydrochloride extended-release Monotherapy Study 1 was a short-term, multi-center, randomized, double-blind, placebo-controlled study of two fixed doses (0.2 mg/day or 0.4 mg/day) of clonidine hydrochloride extended-release in pediatric patients 6 to 17 years of age who met DSM-IV criteria for ADHD hyperactive or combined inattentive/hyperactive subtypes. Most Common Adverse Reactions (incidence of ≥ 5% and at least twice the rate of placebo): somnolence, fatigue, irritability, insomnia, nightmare, constipation, dry mouth.
Adverse Reactions Leading to Discontinuation of clonidine hydrochloride extended-release: Five patients (7%) in the low dose group (0.2 mg), 15 patients (20%) in the high dose group (0.4 mg), and 1 patient in the placebo group (1%) reported adverse reactions that led to discontinuation. The most common adverse reactions that led to discontinuation were somnolence and fatigue. Commonly observed adverse reactions (incidence of ≥2% in either active treatment group and greater than the rate on placebo) during the treatment period are listed in Table 1 .

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS The interactions of ONYDA XR with co-administration of other drugs have not been studied. The drug interaction data provided in this section is based on oral immediate-release clonidine formulations. Table 5 displays clinically important drug interactions with ONYDA XR.
Table 5: Clinically Important Drug Interactions with ONYDA XR Antihypertensive drugs Clinical Implication Concomitant use of antihypertensive drugs with clonidine potentiates the hypotensive effects of clonidine. Intervention Monitor blood pressure and heart rate, and adjust dosage of ONYDA XR accordingly in patients treated concomitantly with antihypertensives [see Warnings and Precautions ( 5.1 )] . CNS depressants Clinical Implication Concomitant use of CNS depressants with clonidine potentiates the sedating effects [see Warnings and Precautions ( 5.2 )] .
Intervention Avoid concomitant use of CNS depressants with ONYDA XR. Drugs that affect sinus node function or AV node conduction (e.g., digitalis, calcium channel blockers, beta blockers) Clinical Implication Concomitant use of drugs that affect sinus node function or AV node conduction with clonidine potentiate bradycardia and risk of AV block [see Warnings and Precautions ( 5.5 )] . Intervention Avoid concomitant use of drugs that affect sinus node function or AV node conduction with ONYDA XR.
Tricyclic antidepressants Clinical Implication Concomitant use of tricyclic antidepressants with clonidine can increase blood pressure and may counteract the hypotensive effects of clonidine. Intervention Monitor blood pressure and adjust dosage of ONYDA XR as needed. CNS Depressants: Clonidine may potentiate the CNS-depressive effects of alcohol, barbiturates or other sedating drugs.
( 7 ) Tricyclic Antidepressants: May reduce the hypotensive effect of clonidine. ( 7 ) Drugs Known to Affect Sinus Node Function or AV Nodal Conduction: Avoid use of ONYDA XR with agents known to affect sinus node function or AV nodal conduction (e.g., digitalis, calcium channel blockers and beta-blockers) due to a potential for additive effects such as bradycardia and AV block. ( 7 ) Antihypertensive drugs: Use caution when coadministered with ONYDA XR.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Renal Impairment: The dosage of ONYDA XR must be adjusted according to the degree of impairment, and patients should be carefully monitored. ( 8.6 , 12.3 )
8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADHD medications, including ONYDA XR, during pregnancy. Healthcare providers are encouraged to advise patients to register by calling the National Pregnancy Registry for Psychiatric Medications at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/adhd-medications/ . Risk Summary Prolonged experience with clonidine in pregnant women over several decades, based on published literature, including controlled trials, a retrospective cohort study and case reports, have not identified a drug associated risk of major birth defects, miscarriage, and adverse maternal or fetal outcomes.
In animal embryofetal studies, increased resorptions were seen in rats and mice administered oral clonidine hydrochloride from implantation through organogenesis at 10 and 5 times, respectively, the maximum recommended human dose (MRHD) given to adolescents on a mg/m 2 basis. No developmental effects were seen in rabbits administered oral clonidine hydrochloride during organogenesis at doses up to 3 times the MRHD (see Data ). The estimated background risk of major birth defects and miscarriage for the indicated population is 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 miscarriages in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Oral administration of clonidine hydrochloride to pregnant rabbits during the period of embryo/fetal organogenesis at doses of up to 80 mcg/kg/day (approximately 3 times the oral maximum recommended daily dose [MRHD] of 0.4 mg/day given to adolescents on a mg/m 2 basis) produced no developmental effects.
In pregnant rats, however, doses as low as 15 mcg/kg/day (1/3 the MRHD given to adolescents on a mg/m 2 basis) were associated with increased resorptions in a study in which dams were treated continuously from 2 months prior to mating and throughout gestation. Increased resorptions were not associated with treatment at the same or at higher dose levels (up to 3 times the MRHD) when treatment of the dams was restricted to gestation days 6-15. Increases in resorptions were observed in both rats and mice at 500 mcg/kg/day (10 and 5 times the MRHD in rats and mice, respectively) or higher when the animals were treated on gestation days 1-14; 500 mcg/kg/day was the lowest dose employed in this study.
8.2Lactation Risk Summary Based on published lactation studies, clonidine hydrochloride is present in human milk at relative infant doses ranging from 4.1% to 8.4% of the maternal weight-adjusted dosage. Although in most cases, there were no reported adverse effects in breastfed infants exposed to clonidine, there is one case report of sedation, hypotonia, and apnea in an infant exposed to clonidine through breast milk. If an infant is exposed to clonidine through breastmilk, monitor for symptoms of hypotension and bradycardia, such as sedation, lethargy, tachypnea and poor feeding (see Clinical Considerations ) .
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ONYDA XR and any potential adverse effects on the breastfed child from ONYDA XR or from the underlying maternal condition. Exercise caution when ONYDA XR is administered to a nursing woman.

🤰 Pregnancy ▾
8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADHD medications, including ONYDA XR, during pregnancy. Healthcare providers are encouraged to advise patients to register by calling the National Pregnancy Registry for Psychiatric Medications at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/adhd-medications/ . Risk Summary Prolonged experience with clonidine in pregnant women over several decades, based on published literature, including controlled trials, a retrospective cohort study and case reports, have not identified a drug associated risk of major birth defects, miscarriage, and adverse maternal or fetal outcomes.
In animal embryofetal studies, increased resorptions were seen in rats and mice administered oral clonidine hydrochloride from implantation through organogenesis at 10 and 5 times, respectively, the maximum recommended human dose (MRHD) given to adolescents on a mg/m 2 basis. No developmental effects were seen in rabbits administered oral clonidine hydrochloride during organogenesis at doses up to 3 times the MRHD (see Data ). The estimated background risk of major birth defects and miscarriage for the indicated population is 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 miscarriages in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Oral administration of clonidine hydrochloride to pregnant rabbits during the period of embryo/fetal organogenesis at doses of up to 80 mcg/kg/day (approximately 3 times the oral maximum recommended daily dose [MRHD] of 0.4 mg/day given to adolescents on a mg/m 2 basis) produced no developmental effects.
In pregnant rats, however, doses as low as 15 mcg/kg/day (1/3 the MRHD given to adolescents on a mg/m 2 basis) were associated with increased resorptions in a study in which dams were treated continuously from 2 months prior to mating and throughout gestation. Increased resorptions were not associated with treatment at the same or at higher dose levels (up to 3 times the MRHD) when treatment of the dams was restricted to gestation days 6-15. Increases in resorptions were observed in both rats and mice at 500 mcg/kg/day (10 and 5 times the MRHD in rats and mice, respectively) or higher when the animals were treated on gestation days 1-14; 500 mcg/kg/day was the lowest dose employed in this study.
🧒 Pediatric Use ▾
8.4Pediatric Use The safety and efficacy of clonidine hydrochloride extended-release in the treatment of ADHD have been established in pediatric patients 6 to 17 years of age. Use of clonidine hydrochloride extended-release in pediatric patients 6 to 17 years of age is supported by three adequate and well-controlled studies; a short-term, placebo-controlled monotherapy trial, a short-term adjunctive therapy trial and a longer-term randomized monotherapy trial [see Clinical Studies ( 14 )]. Safety and efficacy in pediatric patients below the age of 6 years has not been established.
Juvenile Animal Data In studies in juvenile rats, clonidine hydrochloride alone or in combination with methylphenidate had an effect on bone growth at clinically relevant doses and produced a slight delay in sexual maturation in males at 3 times the maximum recommended human dose (MRHD) for clonidine and methylphenidate. In a study where juvenile rats were treated orally with clonidine hydrochloride from day 21 of age to adulthood, a slight delay in onset of preputial separation (delayed sexual maturation) was seen in males treated with 300 mcg/kg/day, which is approximately 3 times the MRHD of 0.4 mg/day on a mg/m 2 basis.
The no-effect dose was 100 mcg/kg/day, which is approximately equal to the MRHD. There was no drug effects on fertility or on other measures of sexual or neurobehavioral development. In a study where juvenile rats were treated with clonidine alone (300 mcg/kg/day) or in combination with methylphenidate (10 mg/kg/day in females and 50/30 mg/kg/day in males; the dose was lowered from 50 to 30 mg/kg/day in males due to self-injurious behavior during the first week of treatment) from day 21 of age to adulthood, decreases in bone mineral density and mineral content were observed in males treated with 300 mcg/kg/day clonidine alone and in combination with 50/30 mg/kg/day methylphenidate and a decrease in femur length was observed in males treated with the combination at the end of the treatment period.
These doses are approximately 3 times the MRHD of 0.4 mg/day clonidine and 54 mg/day methylphenidate on a mg/m 2 basis. All these effects in male were not reversed at the end of a 4-week recovery period. In addition, similar findings were seen in males treated with a lower dose of clonidine (30 mcg/kg/day) in combination with 50 mg/kg/day of methylphenidate and a decrease in femur length was observed in females treated with clonidine alone at the end of the recovery period.
These effects were accompanied by a decrease in body weight gain in treated animals during the treatment period but the effect was reversed at the end of the recovery period. A delay in preputial separation (sexual maturation) was observed in males treated with the combination treatment of 300 mcg/kg/day clonidine and 50/30 mg/kg/day methylphenidate. There was no effect on reproduction or sperm analysis in these males.
🆘 Overdosage ▾
10 OVERDOSAGE Hypertension may develop early and may be followed by hypotension, bradycardia, respiratory depression, hypothermia, drowsiness, decreased or absent reflexes, weakness, irritability and miosis. The frequency of CNS depression may be higher in pediatric patients than adults. Large overdoses may result in reversible cardiac conduction defects or dysrhythmias, apnea, coma and seizures.
Signs and symptoms of overdose generally occur within 30 minutes to two hours after exposure. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Clonidine stimulates alpha 2 -adrenergic receptors in the brain. Clonidine is not a central nervous system stimulant. The mechanism of action of clonidine in ADHD is not known.
12.2Pharmacodynamics Clonidine is a known antihypertensive agent. By stimulating alpha 2 -adrenergic receptors in the brain stem, clonidine reduces sympathetic outflow from the central nervous system and decreases peripheral resistance, renal vascular resistance, heart rate, and blood pressure.
12.3Pharmacokinetics Immediate-release clonidine hydrochloride, extended-release clonidine hydrochloride tablets, and ONYDA XR have different pharmacokinetic characteristics. Dose substitution on a milligram for milligram basis will result in differences in exposures [see Dosage and Administration ( 2.3 )] . Absorption Following a single 0.2 mg dose of ONYDA XR in 20 healthy adult subjects under fasting conditions in a crossover study, the median (range) time to peak plasma concentrations (T max ) for clonidine was 7.50 (4 –17) hours after dosing.
Peak concentration (C max ) was 95.6% of the C max of clonidine extended-release tablet 0.1 mg administered at 0 and 12 hours under fasting conditions. The relative bioavailability of ONYDA XR compared with an equal dose of clonidine extended-release tablet was 96.1%. After oral administration of 0.2 mg of ONYDA XR once daily over 5 days under fasted conditions in healthy adult subjects, the peak steady state plasma concentration (C max .ss) was 107.9%, and steady state relative bioavailability (AUC t , ss) was 97.7% compared with 0.1 mg of clonidine extended-release tablet administered twice daily under fasting conditions.
The minimum concentration at steady state (Cmin,ss) of ONYDA XR was about 26% lower than that of the equal dose of clonidine extended-release tablet. Following oral administration of an immediate release formulation in healthy adult subjects, plasma clonidine concentration peaks in approximately 3 to 5 hours. A comparison across studies suggests that the C max is 50% lower for clonidine hydrochloride extended-release tablets compared to immediate-release clonidine hydrochloride.
Effect of Food Food had no effect on plasma exposures of clonidine after administration of ONYDA XR (see Figure 1 ). Figure 1: Mean Clonidine Concentration-Time Profiles After Single Dose Administration Elimination The plasma half-life of immediate-release clonidine ranges from 12 to 16 hours. The half-life increases up to 41 hours in patients with severe impairment of renal function.
Metabolism About 50% of the absorbed dose is metabolized in the liver. Excretion Following oral administration about 40% to 60% of the absorbed dose is recovered in the urine as unchanged drug in 24 hours. Although studies of the effect of renal impairment and studies of clonidine excretion have not been performed with ONYDA XR, results are expected to be similar to those of the immediate-release formulation.
Specific Populations Pediatric patients Plasma clonidine concentrations in pediatric patients 6 to 17 years (0.1 mg twice daily and 0.2 mg twice daily of clonidine hydrochloride extended-release tablets) with ADHD are greater than those of adults with hypertension, with pediatric patients 6 to 17 years receiving higher doses on a mg/kg basis. Body weight normalized clearance (CL/F) in pediatric patients aged 6 to 17 years was higher than CL/F observed in adults with hypertension. Clonidine concentrations in plasma increased with increases in dose over the dose range of 0.2 to 0.4 mg/day.
Clonidine CL/F was independent of dose administered over the 0.2 to 0.4 mg/day dose range. Clonidine CL/F appeared to decrease slightly with increases in age over the range of 6 to 17 years, and females had a 23% lower CL/F than males. The incidence of "sedation-like" events (somnolence and fatigue) appeared to be independent of clonidine dose or concentration within the studied dose range in the titration… [Excerpted — this section continues on DailyMed.]

🧬 Pharmacokinetics ▾
12.3Pharmacokinetics Immediate-release clonidine hydrochloride, extended-release clonidine hydrochloride tablets, and ONYDA XR have different pharmacokinetic characteristics. Dose substitution on a milligram for milligram basis will result in differences in exposures [see Dosage and Administration ( 2.3 )] . Absorption Following a single 0.2 mg dose of ONYDA XR in 20 healthy adult subjects under fasting conditions in a crossover study, the median (range) time to peak plasma concentrations (T max ) for clonidine was 7.50 (4 –17) hours after dosing.
Peak concentration (C max ) was 95.6% of the C max of clonidine extended-release tablet 0.1 mg administered at 0 and 12 hours under fasting conditions. The relative bioavailability of ONYDA XR compared with an equal dose of clonidine extended-release tablet was 96.1%. After oral administration of 0.2 mg of ONYDA XR once daily over 5 days under fasted conditions in healthy adult subjects, the peak steady state plasma concentration (C max .ss) was 107.9%, and steady state relative bioavailability (AUC t , ss) was 97.7% compared with 0.1 mg of clonidine extended-release tablet administered twice daily under fasting conditions.
The minimum concentration at steady state (Cmin,ss) of ONYDA XR was about 26% lower than that of the equal dose of clonidine extended-release tablet. Following oral administration of an immediate release formulation in healthy adult subjects, plasma clonidine concentration peaks in approximately 3 to 5 hours. A comparison across studies suggests that the C max is 50% lower for clonidine hydrochloride extended-release tablets compared to immediate-release clonidine hydrochloride.
Effect of Food Food had no effect on plasma exposures of clonidine after administration of ONYDA XR (see Figure 1 ). Figure 1: Mean Clonidine Concentration-Time Profiles After Single Dose Administration Elimination The plasma half-life of immediate-release clonidine ranges from 12 to 16 hours. The half-life increases up to 41 hours in patients with severe impairment of renal function.
Metabolism About 50% of the absorbed dose is metabolized in the liver. Excretion Following oral administration about 40% to 60% of the absorbed dose is recovered in the urine as unchanged drug in 24 hours. Although studies of the effect of renal impairment and studies of clonidine excretion have not been performed with ONYDA XR, results are expected to be similar to those of the immediate-release formulation.
Specific Populations Pediatric patients Plasma clonidine concentrations in pediatric patients 6 to 17 years (0.1 mg twice daily and 0.2 mg twice daily of clonidine hydrochloride extended-release tablets) with ADHD are greater than those of adults with hypertension, with pediatric patients 6 to 17 years receiving higher doses on a mg/kg basis. Body weight normalized clearance (CL/F) in pediatric patients aged 6 to 17 years was higher than CL/F observed in adults with hypertension. Clonidine concentrations in plasma increased with increases in dose over the dose range of 0.2 to 0.4 mg/day.
Clonidine CL/F was independent of dose administered over the 0.2 to 0.4 mg/day dose range. Clonidine CL/F appeared to decrease slightly with increases in age over the range of 6 to 17 years, and females had a 23% lower CL/F than males. The incidence of "sedation-like" events (somnolence and fatigue) appeared to be independent of clonidine dose or concentration within the studied dose range in the titration study.
Results from the add-on study showed that clonidine CL/F was 11% higher in patients who were receiving methylphenidate and 44% lower in those receiving amphetamine compared to subjects not on adjunctive therapy. Drug Interaction Studies Alcohol: In an in vitro alcohol-induced dose dumping study, a significantly faster and more variable ONYDA XR drug release was observed in the presence of 20% alcohol, but not with 5% or 10% alcohol, when compared to 0% alcohol.

🔬 Clinical Studies ▾
14 CLINICAL STUDIES The efficacy of ONYDA XR for the treatment of ADHD in pediatric patients 6 years of age and older is based upon adequate and well-controlled studies of clonidine hydrochloride extended-release tablets (referred to as “clonidine hydrochloride extended-release” in this section). The efficacy results of these adequate and well-controlled studies of clonidine hydrochloride extended-release tablets are presented below. Efficacy of clonidine hydrochloride extended-release in the treatment of ADHD was established in pediatric patients 6 to 17 years in: One short-term, placebo-controlled monotherapy trial (Study 1) One short-term adjunctive therapy to psychostimulants trial (Study 2) One randomized withdrawal trial as monotherapy (Study 3) Short-term Monotherapy and Adjunctive Therapy to Psychostimulant Studies for ADHD The efficacy of clonidine hydrochloride extended-release in the treatment of ADHD was established in 2 (one monotherapy and one adjunctive therapy) placebo-controlled trials in pediatric patients aged 6 to 17 years, who met DSM-IV criteria of ADHD hyperactive or combined hyperactive/inattentive subtypes.
Signs and symptoms of ADHD were evaluated using the investigator administered and scored ADHD Rating Scale-IV-Parent Version (ADHDRS-IV) total score including hyperactive/impulsivity and inattentive subscales. Study 1 was an 8-week randomized, double-blind, placebo-controlled, fixed dose study of pediatric patients 6 to 17 years (N=236) with a 5-week primary efficacy endpoint. Patients were randomly assigned to one of the following three treatment groups: clonidine hydrochloride extended-release 0.2 mg/day (N=78), clonidine hydrochloride extended-release 0.4 mg/day (N=80), or placebo (N=78).
Dosing for the clonidine hydrochloride extended-release groups started at 0.1 mg/day and was titrated in increments of 0.1 mg/week to their respective dose (as divided doses). Patients were maintained at their dose for a minimum of 2 weeks before being gradually tapered down to 0.1 mg/day at the last week of treatment. At both doses, improvements in ADHD symptoms were statistically significantly superior in clonidine hydrochloride extended-release-treated patients compared with placebo-treated patients at the end of 5 weeks as measured by the ADHDRS-IV total score ( Table 6 ).
Study 2 was an 8-week randomized, double-blind, placebo-controlled, flexible dose study in pediatric patients 6 to 17 years (N=198) with a 5-week primary efficacy end point. Patients had been treated with a psychostimulant (methylphenidate or amphetamine) for four weeks with inadequate response. Patients were randomly assigned to one of two treatment groups: clonidine hydrochloride extended-release adjunct to a psychostimulant (N=102) or psychostimulant alone (N=96).
The clonidine hydrochloride extended-release dose was initiated at 0.1 mg/day and doses were titrated in increments of 0.1 mg/week up to 0.4 mg/day, as divided doses, over a 3-week period based on tolerability and clinical response. The dose was maintained for a minimum of 2 weeks before being gradually tapered to 0.1 mg/day at the last week of treatment. ADHD symptoms were statistically significantly improved in clonidine hydrochloride extended-release plus stimulant group compared with the stimulant alone group at the end of 5 weeks as measured by the ADHDRS-IV total score ( Table 6 ).
