Pharmacology

đŸ”Ŧ

Mechanism of Action

Dextroamphetamine and amphetamine are non-catecholamine sympathomimetic amines that exert their therapeutic effect in ADHD by increasing the release of norepinephrine and dopamine from presynaptic nerve terminals in the brain, and by blocking the reuptake of these monoamines into the presynaptic neuron. This leads to increased concentrations of norepinephrine and dopamine in the synaptic cleft.
📊

Pharmacokinetics

Absorption:

Bioavailability: High (approximately 75% for d-amphetamine, 50% for l-amphetamine)
Tmax: Mydayis has a triple-bead release system, resulting in three plasma concentration peaks: approximately 4 hours, 8 hours, and 16 hours post-dose.
FoodEffect: Food (high-fat meal) can delay Tmax by approximately 2.5 hours but does not significantly affect AUC or Cmax.

Distribution:

Vd: Approximately 3-4 L/kg
ProteinBinding: Approximately 16-20%
CnssPenetration: Yes

Elimination:

HalfLife: D-amphetamine: 10-13 hours; L-amphetamine: 11-14 hours (pH-dependent)
Clearance: Highly dependent on urinary pH; increased in acidic urine, decreased in alkaline urine.
ExcretionRoute: Renal
Unchanged: Approximately 30-40% (d-amphetamine) and 50% (l-amphetamine) excreted unchanged in urine at normal urinary pH. Up to 70% in acidic urine.
âąī¸

Pharmacodynamics

OnsetOfAction: Approximately 1-2 hours
PeakEffect: Multiple peaks due to triple-bead release (approx. 4, 8, and 16 hours)
DurationOfAction: Up to 16 hours

Drug Interactions

đŸšĢ

Contraindicated Interactions

  • Monoamine Oxidase Inhibitors (MAOIs) or within 14 days of MAOI use (risk of hypertensive crisis)
🔴

Major Interactions

  • Alkalinizing agents (e.g., sodium bicarbonate, acetazolamide, thiazide diuretics) - increase amphetamine levels and prolong half-life, increasing risk of toxicity.
  • Acidifying agents (e.g., ascorbic acid, ammonium chloride) - decrease amphetamine levels and shorten half-life, reducing efficacy.
  • Tricyclic Antidepressants (TCAs) - may potentiate cardiovascular effects of amphetamines.
  • Serotonergic drugs (e.g., SSRIs, SNRIs, triptans, fentanyl, tramadol, St. John's Wort) - increased risk of serotonin syndrome.
  • Antihypertensive agents - amphetamines may antagonize the hypotensive effects.
🟡

Moderate Interactions

  • Proton Pump Inhibitors (PPIs) and H2-receptor antagonists - may increase amphetamine absorption and exposure.
  • CYP2D6 inhibitors (e.g., quinidine, fluoxetine, paroxetine, ritonavir) - may increase amphetamine exposure, though amphetamine metabolism by CYP2D6 is minor.
  • Antipsychotics (e.g., phenothiazines, haloperidol) - may antagonize the stimulant effects of amphetamines.
  • Lithium - may inhibit the stimulant effects of amphetamines.
đŸŸĸ

Minor Interactions

  • Alcohol - may alter the release profile of extended-release formulations, leading to dose dumping.
  • Antacids - may increase absorption.

Monitoring

đŸ”Ŧ

Baseline Monitoring

Cardiovascular assessment (BP, HR, ECG if indicated)

Rationale: To identify pre-existing cardiac conditions that may contraindicate stimulant use or require close monitoring.

Timing: Prior to initiation

Psychiatric history and assessment

Rationale: To screen for bipolar disorder, psychosis, or other psychiatric conditions that may be exacerbated by stimulants.

Timing: Prior to initiation

Height and weight (pediatric patients)

Rationale: To establish baseline for monitoring potential growth suppression.

Timing: Prior to initiation

📊

Routine Monitoring

Blood Pressure (BP) and Heart Rate (HR)

Frequency: At each visit or at least every 3-6 months

Target: Within normal limits for age/patient

Action Threshold: Persistent elevation (e.g., >95th percentile for age/sex/height or significant increase from baseline) warrants investigation and potential dose adjustment or discontinuation.

Weight and Height (pediatric patients)

Frequency: Every 3-6 months

Target: Consistent growth along established growth curves

Action Threshold: Significant growth deceleration or weight loss warrants investigation, nutritional counseling, and potential drug holiday or alternative treatment.

Psychiatric status (mood, anxiety, psychosis, aggression)

Frequency: At each visit

Target: Stable or improved psychiatric symptoms

Action Threshold: Emergence or worsening of psychotic symptoms, mania, severe anxiety, or aggression warrants immediate evaluation and potential discontinuation.

ADHD symptom control and functional improvement

Frequency: At each visit

Target: Improved attention, reduced hyperactivity/impulsivity, improved academic/social functioning

Action Threshold: Lack of efficacy or worsening symptoms may indicate need for dose adjustment or alternative therapy.

đŸ‘ī¸

Symptom Monitoring

  • Chest pain
  • Shortness of breath
  • Syncope
  • Palpitations
  • New or worsening aggression
  • New or worsening psychotic symptoms (e.g., hallucinations, delusions)
  • New or worsening manic symptoms
  • Severe anxiety or agitation
  • Unexplained weight loss
  • Sleep disturbances

Special Patient Groups

🤰

Pregnancy

Use during pregnancy should be avoided unless the potential benefit justifies the potential risk to the fetus. Amphetamines may cause fetal harm, including premature birth and low birth weight. Neonates exposed to amphetamines during the third trimester may experience withdrawal symptoms.

Trimester-Specific Risks:

First Trimester: Limited data, but potential for increased risk of congenital malformations cannot be ruled out.
Second Trimester: Potential for adverse pregnancy outcomes (e.g., premature birth, low birth weight).
Third Trimester: Risk of neonatal withdrawal symptoms (e.g., agitation, feeding difficulties, tremor, hypertonia, somnolence, respiratory distress) and potential for premature birth and low birth weight.
🤱

Lactation

Amphetamines are excreted into human milk. Due to the potential for serious adverse reactions in breastfed infants (e.g., irritability, poor feeding, sleep disturbances, growth suppression, cardiovascular effects), breastfeeding is not recommended during treatment with Mydayis.

Infant Risk: High (L3 - Moderately hazardous, L4 - Potentially hazardous, depending on dose and infant sensitivity)
đŸ‘ļ

Pediatric Use

Approved for children 6 years and older. Monitor growth (height and weight) carefully, as stimulants have been associated with growth suppression. Psychiatric and cardiovascular monitoring is crucial.

👴

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

  • Mydayis offers a long duration of action (up to 16 hours) due to its triple-bead release technology, which may be beneficial for patients needing symptom control throughout the school/work day and into the evening.
  • Patients should be advised not to open, chew, or crush the capsules to maintain the extended-release properties and prevent dose dumping.
  • Careful cardiovascular screening is essential before initiating treatment, especially in patients with pre-existing cardiac conditions or a family history of sudden cardiac death.
  • Regular monitoring of blood pressure, heart rate, and growth (in children) is critical throughout treatment.
  • Educate patients and caregivers about the signs of stimulant-induced psychosis or mania, and the importance of reporting these symptoms immediately.
  • Consider drug holidays or dose adjustments if growth suppression is observed in pediatric patients.
🔄

Alternative Therapies

  • Methylphenidate extended-release formulations (e.g., Concerta, Ritalin LA, Quillivant XR, Adhansia XR)
  • Non-stimulants (e.g., Strattera (atomoxetine), Intuniv (guanfacine ER), Kapvay (clonidine ER))
  • Behavioral therapy and psychotherapy for ADHD
