Pharmacology

đŸ”Ŧ

Mechanism of Action

Lisdexamfetamine is a prodrug that is converted to dextroamphetamine. Dextroamphetamine is a non-catecholamine sympathomimetic amine that exerts its therapeutic effect by releasing norepinephrine and dopamine from nerve terminals in the brain, primarily in the prefrontal cortex. It also inhibits the reuptake of these monoamines.

Precautions & Cautions

It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication. This drug is not intended for weight loss, so if you have any questions or concerns, discuss them with your doctor.

To ensure your safety, avoid driving and other activities that require alertness and clear vision until you understand how this medication affects you. If you have been taking this drug for an extended period or at high doses, you may develop tolerance, which means it may not work as effectively, and you may need higher doses to achieve the same effect. If you notice this medication is not working as well as it should, contact your doctor. Do not exceed the prescribed dose.

Long-term or regular use of this medication can lead to dependence, and suddenly stopping it may cause withdrawal symptoms. Before reducing the dose or stopping this medication, consult your doctor, and follow their instructions carefully. Report any adverse effects to your doctor.

Before starting this medication, you may need to undergo certain heart tests. If you have any questions or concerns, discuss them with your doctor. This drug can cause high blood pressure, so it is crucial to monitor your blood pressure and heart rate as directed by your doctor.

Additionally, this medication may affect the results of certain laboratory tests. Inform all your healthcare providers and laboratory personnel that you are taking this medication. Before using any over-the-counter (OTC) products that may increase blood pressure, such as cough or cold medications, diet pills, stimulants, non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, or certain natural products or aids, consult your doctor.

Be aware that a severe skin reaction, known as Stevens-Johnson syndrome or toxic epidermal necrolysis, can occur with this medication. This condition can cause severe health problems that may be permanent or even life-threatening. Seek immediate medical attention if you experience symptoms such as red, swollen, blistered, or peeling skin (with or without fever), red or irritated eyes, or sores in your mouth, throat, nose, or eyes.

This medication can also cause changes in behavior and mood, including hallucinations, anger, and changes in thinking. If you or a family member have a history of mental or mood problems, such as depression or bipolar disorder, or if a family member has committed suicide, inform your doctor. If you experience hallucinations, changes in behavior, or mood changes such as depression, thoughts of suicide, nervousness, emotional instability, abnormal thinking, anxiety, or loss of interest in life, contact your doctor immediately.

In some cases, this medication can affect growth in children and adolescents, so they may require regular growth checks. Discuss this with your doctor. This medication is not approved for use in children under 6 years of age, as it may increase the risk of long-term weight loss in this age group.

Drug Interactions

đŸšĢ

Contraindicated Interactions

  • Monoamine Oxidase Inhibitors (MAOIs) - concurrent use or within 14 days of MAOI discontinuation (risk of hypertensive crisis, serotonin syndrome)
🔴

Major Interactions

  • Serotonergic drugs (SSRIs, SNRIs, TCAs, triptans, fentanyl, lithium, tramadol, St. John's Wort) - increased risk of serotonin syndrome
  • Antihypertensives - may decrease hypotensive effect
  • Urinary alkalinizers (e.g., sodium bicarbonate, acetazolamide, thiazide diuretics) - increase dextroamphetamine blood levels and prolong half-life
  • Urinary acidifiers (e.g., ammonium chloride, ascorbic acid) - decrease dextroamphetamine blood levels and shorten half-life
🟡

Moderate Interactions

  • Adrenergic blockers (e.g., guanethidine) - amphetamines may antagonize effects
  • Antidepressants (e.g., TCAs) - may potentiate cardiovascular effects of amphetamines
  • Antipsychotics (e.g., phenothiazines, haloperidol) - may antagonize stimulant effects
  • Proton pump inhibitors (PPIs) - no significant interaction expected as lisdexamfetamine hydrolysis is not pH-dependent.
đŸŸĸ

Minor Interactions

  • Not specifically listed for minor severity, but general caution with other CNS stimulants or drugs affecting heart rate/blood pressure.

Special Patient Groups

🤰

Pregnancy

Use during pregnancy should be considered only if the potential benefit justifies the potential risk to the fetus. Amphetamines can cause fetal harm, including premature delivery and low birth weight. Neonates exposed to amphetamines during pregnancy may experience withdrawal symptoms.

Trimester-Specific Risks:

First Trimester: Potential for congenital malformations, though data are limited and inconsistent.
Second Trimester: Risk of premature delivery and low birth weight.
Third Trimester: Risk of withdrawal symptoms in the neonate (e.g., agitation, feeding difficulties, tremor, hypotonia, respiratory distress).
🤱

Lactation

Dextroamphetamine is excreted into human milk. Breastfeeding is not recommended during treatment with lisdexamfetamine due to the potential for serious adverse reactions in the infant (e.g., irritability, poor feeding, sleep disturbances, weight loss).

Infant Risk: L3 (Moderate risk - Amphetamines are excreted into breast milk and can cause adverse effects in the infant. Monitor for irritability, sleep disturbances, poor feeding, and weight loss. Consider alternatives or pump and discard milk.)
đŸ‘ļ

Pediatric Use

Approved for ADHD in children 6 years and older. Monitor growth (height and weight) regularly. Long-term effects on growth are a concern. Safety and efficacy in children under 6 years have not been established.

👴

Geriatric Use

Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Generally, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Clinical Information

💎

Clinical Pearls

  • Vyvanse is a prodrug, meaning it is inactive until converted in the body, which contributes to its smoother onset and longer duration of action compared to immediate-release amphetamines.
  • The chewable tablet can be chewed thoroughly or dissolved in water, orange juice, or yogurt, offering flexibility for administration.
  • Due to its prodrug nature, crushing or dissolving Vyvanse does not bypass the conversion process, reducing its abuse potential via injection or snorting compared to other stimulants.
  • Always take in the morning to avoid insomnia, even if a dose is missed, do not take it later in the day.
  • Monitor for signs of stimulant-induced psychosis or mania, especially in patients with a personal or family history of psychiatric disorders.
  • Regular cardiovascular monitoring is crucial due to the risk of increased blood pressure and heart rate.
🔄

Alternative Therapies

  • Methylphenidate (e.g., Ritalin, Concerta, Focalin)
  • Mixed amphetamine salts (e.g., Adderall, Mydayis)
  • Non-stimulants (e.g., Atomoxetine, Guanfacine ER, Clonidine ER)
  • Behavioral therapy (for ADHD and BED)
  • Cognitive Behavioral Therapy (CBT) (for BED)
