Amphetamines and Methylphenidate: According to the AAP (American Academy of Pediatrics) at least 80% of ADHD patients will respond positively to stimulants if used in a systematic fashion. 69.3% of kids with diagnosed ADHD take medication.
Psychostimulants are considered first line agents for ADHD, unless the patient has a history of:
- substance abuse
- bipolar disorder
- active psychotic disorder.
The use of ADHD drugs is on the rise as more adults are being diagnosed with ADHD.
ADULTS: 4.4% of adult population is diagnosed with ADHD, although believed to be higher. There is an 85% risk of adult ADHD if diagnosed as a child.
Considerations before prescribing amphetamines/ methylphenidate:
- Stimulants increase blood pressure by 3 to 4 mmHg and heart rate by 1 to 2 beats per minute, on average, in children and adolescents.
- In adults, they can increase systolic blood pressure by about 5 mmHg. These effects raise concern that stimulants may increase the risk of cardiovascular events
- A weekend drug holiday might be effective for managing insomnia or appetite suppression; may also be tried to reduce effect on growth, especially in patients with a family history of short stature.
- Stimulants and atomoxetine are unlikely to increase stroke, heart attacks, or sudden death. Still avoid them in patients with serious heart problems, or if blood pressure or heart rate increase would be a problem. Adderall was temporarily removed from the Canadian market due to these adverse effects
- Regardless of chosen medication, monitor heart rate, blood pressure, height, and weight.
- Cases of painful and prolonged penile erections and priapism have been reported with methylphenidate products
- Tolerance to stimulants unlikely. Plateau effect after first week is not tolerance.
- Stimulant dose based on weight, disease severity, and target symptoms (hyperactivity may require higher doses than inattentiveness).
- Long-acting medications just as effective as shorter-acting agents. Long-acting agents usually preferred for convenience and to minimize breakthrough symptoms, irritability, and headache.
- Common side effects include anorexia, abdominal pain, insomnia, and headache.
- Rarely, stimulants may cause psychotic symptoms such as hallucinations. Final adult height might be decreased by less than an inch
BENEFITS of TREATMENT
Treatment of ADHD with stimulants and psychotherapy has been shown to decrease disruptive behaviors and improve academic performance, self-esteem, cognition, and personal relationships. In addition, it has been reported that ADHD children treated with stimulant therapy during childhood are at lower risk for drug and alcohol abuse when they are older than those who are not treated.
