Pharmacology

The exact mechanism of lisdexamfetamine in ADHD and binge eating disorder is not known. Lisdexamfetamine dimesylate is a prodrug that is converted to the active component dextroamphetamine (a noncatecholamine, sympathomimetic amine). Amphetamines are noncatecholamine, sympathomimetic amines that cause release of catecholamines (primarily dopamine and norepinephrine) from their storage sites in the presynaptic nerve terminals. A less significant mechanism may include their ability to block the reuptake of catecholamines by competitive inhibition.

Absorption

Rapid

Metabolism

Metabolized in the blood by hydrolytic activity of red blood cells to dextroamphetamine and l-lysine; does not undergo CYP mediated metabolism

Urine (96%, 42% as amphetamine-related compounds, 2% as lisdexamfetamine, 25% hippuric acid); feces (minimal)

ALERT: U.S. Boxed Warning

Abuse and dependence:

CNS stimulants (amphetamines and methylphenidate-containing products), including lisdexamfetamine, have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing and monitor for signs of abuse and dependence while on therapy.

Warnings/Precautions

Concerns related to adverse effects:

• Cardiovascular events: Stimulant use has been associated with serious cardiovascular events including sudden death in patients with preexisting structural cardiac abnormalities or other serious heart problems (sudden death in children and adolescents; sudden death, stroke, and MI in adults). Consistent with other studies, a large retrospective cohort study involving 1,200,438 children, adolescents, and young adults (aged 2 to 24 years) prescribed methylphenidate, dexmethylphenidate, dextroamphetamines, amphetamine salts, pemoline, or atomoxetine found no evidence that current use of an ADHD medication increased risk for sudden cardiac death, acute MI, or stroke (Cooper 2011). Stimulants should be avoided in patients with known structural cardiac abnormalities, cardiomyopathy, serious heart rhythm abnormalities, coronary artery disease, Marfan syndrome, or other serious cardiac problems. Some products are contraindicated in patients with moderate or severe hypertension. Prior to initiating stimulant, assess medical history and family history of sudden death or ventricular arrhythmia; conduct a physical exam to assess for cardiac disease; patients should receive further evaluation if findings suggest cardiac disease, such as ECG and echocardiogram. Promptly conduct cardiac evaluation in patients who develop exertional chest pain, unexplained syncope, or any other symptoms of cardiac disease during stimulant treatment.

• CNS effects: Amphetamines may impair the ability to engage in potentially hazardous activities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).

• Hypersensitivity: Hypersensitivity reactions, including anaphylaxis, Stevens-Johnson syndrome, angioedema, and urticaria have been observed.

• Peripheral vasculopathy: Stimulants are associated with peripheral vasculopathy, including Raynaud phenomenon; signs/symptoms are usually mild and intermittent, and generally improve with dose reduction or discontinuation. Peripheral vasculopathy effects have been observed at different times, at therapeutic doses, and in all age groups. Digital ulceration and/or soft tissue breakdown have been observed rarely; monitor for digital changes during therapy and seek further evaluation (eg, rheumatology) if necessary.

• Visual disturbance: Difficulty in accommodation and blurred vision has been reported with the use of stimulants.

Disease-related concerns:

• Cardiovascular disorders: CNS stimulants may increase heart rate and blood pressure; the observed mean increase in heart rate was 3 to 6 bpm and blood pressure was 2 to 4 mm Hg. Use with caution in patients with hypertension, heart failure, recent MI, ventricular arrhythmia, and other cardiovascular conditions that might be exacerbated by increases in blood pressure or heart rate. Some products are contraindicated in patients with moderate to severe hypertension or hyperthyroidism.

• Psychiatric disorders: Use with caution in patients with preexisting psychosis or bipolar disorder (may induce mixed/manic episode). May exacerbate symptoms of behavior and thought disorder in psychotic patients; new onset psychosis or mania may occur in children or adolescents with stimulant use. Patients should be screened for bipolar disorder and risk factors for developing mania prior to treatment; consider discontinuation if such symptoms (eg, delusional thinking, hallucinations, or mania) occur. May be associated with aggressive behavior or hostility (causal relationship not established); monitor for development or worsening of these behaviors.

• Seizure disorder: Limited information exists regarding stimulant use in seizure disorder. Whereas patients with ADHD are at an increased risk for seizure activity compared to the general population, a retrospective study using drug claims data showed that the use of stimulant medications was associated with a lower risk (Cortese 2013; Wiggs 2018). Manufacturers of some stimulants recommend discontinuing therapy if seizures occur.

• Tourette syndrome/tics: Use with caution in patients with Tourette syndrome or other tic disorders. Stimulants may exacerbate tics (motor and phonic) and Tourette syndrome; however, evidence demonstrating increased tics is limited. Evaluate for tics and Tourette syndrome prior to therapy initiation (AACAP [Murphy 2013]; Pliszka 2007).

Concurrent drug therapy issues:

• Serotonin syndrome: Potentially life-threatening serotonin syndrome (SS) may occur when lisdexamfetamine is used in combination with other serotonergic agents (eg, selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, buspirone, St. John's wort, tryptophan), agents that impair metabolism of serotonin (eg, monoamine oxidase inhibitors) or CYP2D6 inhibitors that impair metabolism of lisdexamfetamine. Concomitant use with monoamine oxidase inhibitors is contraindicated. If concomitant use of lisdexamfetamine with serotonergic drugs or CYP2D6 inhibitors is indicated, initiate lisdexamfetamine at a low dose and monitor patient closely for signs and symptoms of SS. Discontinue treatment (and any concomitant serotonergic agent) immediately if signs/symptoms arise.

Special populations:

• Elderly: Use caution in this age group due to CNS stimulant adverse effects.

• Pediatric: Appetite suppression may occur; particularly in children. Use of stimulants has been associated with weight loss and slowing of growth rate; monitor growth rate and weight during treatment. Treatment interruption may be necessary in patients who are not increasing in height or gaining weight as expected.

Other warnings/precautions:

• Abuse/misuse/diversion: [US Boxed Warning]: Has high potential for abuse and dependence; assess for abuse potential prior to use and monitor for signs of abuse and dependence while on therapy. Use with caution in patients with a history of ethanol or drug abuse. Prescriptions should be written for the smallest quantity consistent with good patient care to minimize possibility of overdose.

• ADHD treatment: Appropriate use: Recommended to be used as part of a comprehensive treatment program for attention deficit disorders.

• Weight loss: Appropriate use: Not indicated or recommended for weight loss; safety and efficacy not established for treatment of obesity.

• Discontinuation of therapy: Abrupt discontinuation following high doses or for prolonged periods may result in symptoms for withdrawal (eg, depression, extreme fatigue).

Monitoring Parameters

Cardiac evaluation should be completed at baseline and on any patient who develops exertional chest pain, unexplained syncope, and any symptom of cardiac disease during treatment with stimulants. Monitor blood pressure and heart rate (baseline, following dose increases and periodically during treatment); growth rate (height and weight) and appetite in children; weight in adults; signs of peripheral vasculopathy (eg, digital changes); sleep and behavioral changes. Assess for risk of abuse prior to prescribing and signs of misuse, abuse, or addiction throughout treatment (NICE 2018).

Pregnancy Considerations

Lisdexamfetamine is converted to dextroamphetamine. The majority of human data is based on illicit amphetamine/methamphetamine exposure and not from therapeutic maternal use (Golub 2005). Use of amphetamines during pregnancy may lead to an increased risk of premature birth and low birth weight; newborns may experience symptoms of withdrawal. Behavioral problems may also occur later in childhood (LaGasse 2012).
