gov/medwatch . 1 Clinical 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 clinical practice.
The safety of amphetamine extended-release orally disintegrating tablets has been established from adequate and well-controlled studies of single-entity amphetamine product extended-release (MAS ER) capsules [see Clinical Studies ( 14 )] .
The adverse reactions of MAS ER capsules in these adequate and well-controlled studies are described below. The premarketing development program for MAS ER included exposures in a total of 1,315 participants in clinical trials (635 pediatric patients, 350 adolescent patients, 248 adult patients, and 82 healthy adult subjects).
Of these, 635 patients (ages 6 to 12 years) were evaluated in two controlled clinical studies, one open-label clinical study, and two single-dose clinical pharmacology studies (N=40). 7%). 1%) discontinued treatment due to adverse events among MAS ER-treated patients (N=233) compared to 0% who received placebo (N=54).

The use of amphetamine extended-release orally disintegrating tablets exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. 2 )] . Misuse and abuse of CNS stimulants, including amphetamine extended-release orally disintegrating tablets, can result in overdose and death [see Overdosage ( 10 )] , and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection.
Before prescribing amphetamine extended-release orally disintegrating tablets, assess each patient’s risk for abuse, misuse, and addiction. Educate patients and their families about these risks and proper disposal of any unused drug.
Advise patients to store amphetamine extended-release orally disintegrating tablets in a safe place, preferably locked, and instruct patients to not give amphetamine extended-release orally disintegrating tablets to anyone else. Throughout amphetamine extended-release orally disintegrating tablets treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction.
2 Risks to Patients with Serious Cardiac Disease Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who were treated with CNS stimulants at the recommended ADHD dosage.
Avoid amphetamine extended-release orally disintegrating tablets use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease. 3 Increased Blood Pressure and Heart Rate CNS stimulants cause an increase in blood pressure (mean increase about 2 to 4 mm Hg) and heart rate (mean increase about 3 to 6 bpm).
Some patients may have larger increases. Monitor all amphetamine extended-release orally disintegrating tablets-treated patients for potential tachycardia and hypertension. 4 Psychiatric Adverse Reactions Exacerbation of Pre-existing Psychosis CNS stimulants may exacerbate symptoms of behavior disturbance and thought disorder in patients with a pre-existing psychotic disorder.
Induction of a Manic Episode in Patients with Bipolar Disorder CNS stimulants may induce a manic or mixed episode in patients. , comorbid or has a history of depressive symptoms or a family history of suicide, bipolar disorder, and depression).
, hallucinations, delusional thinking, or mania in patients without prior history of psychotic illness or mania. 1% of CNS stimulant-treated patients compared to 0% of placebo-treated patients. If such symptoms occur, consider discontinuing amphetamine extended-release orally disintegrating tablets.
4 )] . CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients. Closely monitor growth (weight and height) in amphetamine extended-release orally disintegrating tablets-treated pediatric patients treated with CNS stimulants.
Pediatric patients not growing or gaining height or weight as expected may need to have their treatment interrupted. 6 Peripheral Vasculopathy, including Raynaud’s Phenomenon CNS stimulants, including amphetamine extended-release orally disintegrating tablets, used to treat ADHD are associated with peripheral vasculopathy, including Raynaud’s phenomenon.
Signs and symptoms are usually intermittent and mild; however, sequelae have included digital ulceration and/or soft tissue breakdown. Effects of peripheral vasculopathy, including Raynaud’s phenomenon, were observed in postmarketing reports and at the therapeutic dosage of CNS stimulants in all age groups throughout the course of treatment.
Signs and symptoms generally improved after dosage reduction or discontinuation of the CNS stimulant. Careful observation for digital changes is necessary during amphetamine extended-release orally disintegrating tablets-treatment. , rheumatology referral) may be appropriate for amphetamine extended-release orally disintegrating tablets-treated patients who develop signs or symptoms of peripheral vasculopathy.
7 Serotonin Syndrome Serotonin syndrome, a potentially life-threatening reaction, may occur when amphetamines are used in combination with other drugs that affect the serotonergic neurotransmitter systems such as monoamine oxidase inhibitors (MAOIs), selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and St.

Concomitant use of amphetamine extended-release orally disintegrating tablets with MAOI drugs is contraindicated [see Contraindications ( 4 )] .
Discontinue treatment with amphetamine extended-release orally disintegrating tablets and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of amphetamine extended-release orally disintegrating tablets with other serotonergic drugs or CYP2D6 inhibitors is clinically warranted, initiate amphetamine extended-release orally disintegrating tablets with lower doses, monitor patients for the emergence of serotonin syndrome during drug initiation or titration, and inform patients of the increased risk for serotonin syndrome.
8 Motor and Verbal Tics, and Worsening of Tourette’s Syndrome CNS stimulants, including amphetamine, have been associated with the onset or exacerbation of motor and verbal tics. 2 )] . Before initiating amphetamine extended-release orally disintegrating tablets, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome.
Regularly monitor amphetamine extended-release orally disintegrating tablets-treated patients for the emergence or worsening of tics or Tourette’s syndrome and discontinue treatment if clinically appropriate. 9 Potential for Overdose Due to Medication Errors Medication errors, including substitution and dispensing errors, between amphetamine extended-release orally disintegrating tablets and other amphetamine products could occur, leading to possible overdosage.
