Chapter 14: CNS Stimulants & ADHD Medications

CNS Stimulants & ADHD Medications medications are therapeutically grouped into five major categories: anti-attention deficit/hyperactivity disorder (ADHD), antinarcoleptic, anorexiant, antimigraine, and analeptic drugs. Treatment for ADHD and narcolepsy relies heavily on amphetamines and related synthetic drugs like methylphenidate, which are potent Schedule III controlled substances due to their potential for tolerance and dependence. Nonstimulant options, such as the norepinephrine reuptake inhibitor atomoxetine, are also utilized for ADHD, offering a lower potential for misuse. For obesity management, anorexiants work to suppress appetite, often including nonstimulant lipase inhibitors like orlistat, which block fat absorption locally in the intestines. Acute migraine headaches are treated using antimigraine drugs, primarily serotonin receptor agonists (triptans), which cause cerebral vasoconstriction to relieve pain, replacing older ergot alkaloids as first-line therapy. Finally, analeptics, such as methylxanthines like caffeine and theophylline, are respiratory stimulants acting mainly on the medulla and spinal cord. Since CNS stimulants "speed up" body systems, essential nursing care involves a thorough baseline assessment of the patient’s cardiovascular health, mental status, and nutritional patterns, with continuous monitoring for adverse effects like hypertension, insomnia, and the potential for new or worsening psychiatric disorders.
