Adzenys ER, Adzenys-XR ODT, Dyanavel XR, Evekeo

• Causes release of norepinephrine from nerve endings. Pharmacologic effects are:
  • CNS and respiratory stimulation,
  • Vasoconstriction,
  • Mydriasis (pupillary dilation).

• Increased attention span in ADHD.
• Increased motor activity, mental alertness, and decreased fatigue in narcolepsy.
• Weight reduction.

Therapeutic Classification: central nervous system stimulants

Absorption: Well absorbed after oral administration.

Distribution: Widely distributed in body tissues, with high concentrations in the brain and CSF.

Metabolism/Excretion: Some metabolism by the liver. Urinary excretion is pH-dependent. Alkaline urine promotes reabsorption and prolongs action.

Half-life: 10–15 hr.

Schedule II (C-II)

(CNS stimulation)

• Instruct patient to take medication once in the morning as directed. Do not double doses. Instruct patient not to alter dose without consulting health care professional.

• Inform patient that the effects of drug-induced dry mouth can be minimized by rinsing frequently with water or chewing sugarless gum or candies.
• Advise patient to limit caffeine intake.
• May impair judgment. Advise patient to use caution when driving or during other activities requiring alertness until response to medication is known.
• Advise patient/parent to notify health care professional promptly if signs and symptoms of heart problems (chest pain, shortness of breath, fainting), mental problems (new or worsening behaviors, thoughts, or mental symptoms; hearing voices; believing things that are not true; being suspicious; new manic symptoms), serotonin syndrome, or circulation problems in fingers and toes (numb, cool, painful, change from pale to blue or red, unexplained wounds on fingers or toes) occur.

Monitor infants born to mothers taking amphetamines for symptoms of withdrawal (feeding difficulties, irritability, agitation, excessive drowsiness). Encourage patients exposed to amphetamines during pregnancy to join the registry. Health care professionals may call the National Pregnancy Registry for Psychiatric Medications at 1-866-961-2388 or online at womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/othermedications/ to register patients.
