Study Notes

Treatment Goals for ADHD

Primary goal: Reduce symptoms to enable functioning in all environments.
ADHD is not curable; management focuses on symptom improvement rather than elimination.

First-Line Therapies

Stimulants are the first-line therapy for treating ADHD.
Atomoxetine is a second-line option if stimulants fail.

ADHD Diagnosis Types

ADHD combined is characterized by inattention, hyperactivity, and impulsivity.
ADHD predominantly inattentive subtype shows difficulty focusing without hyperactivity.

Symptoms Across Ages

In adults, inattention is the most common symptom of ADHD.
Hyperactivity tends to dominate in children, while inattention is more prevalent in adults.

Nonpharmacologic Treatments

EndeavorRx, a game-based device, is an approved nonpharmacologic treatment for children with ADHD.
Cognitive Behavioral Therapy (CBT) is effective for adults with ADHD, though less effective than stimulants.

Treatment Age Guidelines

Children aged 4-5 years should start ADHD treatment with behavioral therapy instead of medication.
Stimulant medications are recommended for children aged 6-18 years as the first-line treatment.

Stimulant Therapy Considerations

Monoamine oxidase inhibitors (MAOIs) should not be used with stimulants due to the risk of hypertensive crisis.
Combining methylphenidate with clonidine can lead to increased cardiovascular effects.

Atomoxetine Overview

Atomoxetine (Strattera) works by inhibiting norepinephrine reuptake.
Potential adverse effect includes hepatotoxicity.
Full efficacy of atomoxetine is reached in approximately 4 weeks.

Clonidine and Guanfacine (Alpha-2 Agonists)

Clonidine and guanfacine act primarily by stimulating alpha-2 adrenergic receptors, which helps in treating ADHD.
A common side effect of clonidine includes hypotension, affecting blood pressure regulation.
Guanfacine is noted for being less sedating compared to clonidine, making it preferable in certain cases.

Alpha-2 Agonists: Side Effects and Use

Drowsiness is a frequently observed adverse effect when using alpha-2 agonists for ADHD treatment.
Abrupt cessation of clonidine can lead to a hypertensive crisis, necessitating careful management of dosage.
Clonidine is FDA-approved for treating both ADHD and hypertension, showcasing its versatility.

Non-Stimulant Medications

Atomoxetine is recognized as the FDA-approved non-stimulant medication specifically for ADHD.
A significant advantage of atomoxetine is its lower risk of abuse compared to stimulant medications, an important consideration in ADHD treatment.
The therapeutic effects of atomoxetine typically manifest within 4 to 6 weeks, indicating a longer initiation period compared to stimulant medications.

Atomoxetine Adverse Effects

Hepatotoxicity is a serious potential side effect of atomoxetine that requires close monitoring of liver function.
Gastrointestinal upset is a more common adverse effect noted in children on atomoxetine, which may affect adherence to treatment.
Regular monitoring of liver function tests is essential for patients receiving atomoxetine to prevent serious complications.

Combination Therapy

Combination therapy for ADHD is utilized when a single drug does not sufficiently control symptoms, aiming for enhanced treatment efficacy.
Commonly combined classes in ADHD treatment include stimulants and alpha-2 agonists, leveraging their complementary effects.
The primary goal of combination therapy is to enhance efficacy while managing side effects, providing a more tailored approach to treatment.

Non-Stimulants (Atomoxetine)

Atomoxetine is the only non-stimulant medication approved specifically for ADHD treatment.
A common adverse effect of atomoxetine is hepatotoxicity, posing a risk for liver damage.
Therapeutic effects of atomoxetine typically manifest after 4-6 weeks of treatment.

Non-Stimulant Therapy

Atomoxetine acts as a norepinephrine reuptake inhibitor in ADHD management.
Preference for atomoxetine over stimulant medications arises due to its lower risk of abuse and dependence.
Monitoring of liver function is recommended while using atomoxetine to prevent potential liver complications.

Alpha-2 Agonists

Clonidine and guanfacine are alpha-2 agonists used to treat hyperactivity and impulsivity symptoms in ADHD.
Common side effects of these agonists include sedation, affecting daily functioning.
When used in combination with stimulants, alpha-2 agonists help reduce hyperactivity symptoms and offer sedative benefits.

Bupropion

Bupropion, utilized off-label for ADHD, primarily influences dopamine and norepinephrine neurotransmitter systems.
A significant contraindication for bupropion use includes the presence of seizure disorders, increasing the risk of seizures.
Insomnia is a common side effect associated with bupropion in ADHD treatment.

Viloxazine (Qelbree)

Viloxazine operates through norepinephrine reuptake inhibition as its mechanism of action.
This medication is approved for treating ADHD in patients aged 6 years and older, expanding treatment options for children.
A potential adverse effect of viloxazine includes increased blood pressure and heart rate, requiring monitoring during treatment.

Stimulants: Abuse and Dependence

Common adverse effect of stimulant abuse includes tremors and cardiac arrhythmias.
Signs of stimulant withdrawal feature mental depression and lethargy.
Stimulant drugs like amphetamines primarily affect dopamine and norepinephrine neurotransmitters.

Stimulants: Treatment of Overdose

Recommended treatment for stimulant overdose involves supportive care and seizure control.
Hypertensive crisis is the most common cardiovascular complication linked to stimulant overdose.
Bradycardia is NOT a typical symptom of stimulant overdose; common symptoms include hyperreflexia, hyperthermia, and seizures.

Cocaine Abuse and Effects

Cocaine acts by inhibiting dopamine reuptake, significantly affecting mood and behavior.
Chronic cocaine abuse may lead to complications such as cerebral hemorrhage.
A notable feature of cocaine withdrawal is severe mood depression.

Amphetamines: Abuse and Overdose

Hallucinations and paranoia are common psychiatric symptoms of chronic amphetamine abuse.
Characteristic signs of amphetamine overdose include hypertension, tachycardia, and seizures.
Treatment for severe amphetamine toxicity requires supportive care and managing hyperthermia and seizures.

Withdrawal Symptoms from Stimulants

During stimulant withdrawal, symptoms such as excessive sleep and mental depression are prevalent.
Management of stimulant withdrawal typically includes psychosocial support and symptomatic treatment.
Stimulant tolerance is marked by the necessity for progressively higher doses to achieve the same effects.

Amphetamines

Common overdose symptoms include tachycardia (rapid heartbeat) and hyperthermia (elevated body temperature).
Primary neurotransmitter affected by amphetamines is dopamine, influencing mood and energy levels.
Chronic use leads to withdrawal symptoms such as sleepiness and mental depression.

Cocaine

Cocaine inhibits the reuptake of serotonin, norepinephrine, and dopamine, enhancing their effects in the brain.
Fatalities in cocaine overdose are often caused by respiratory depression and arrhythmias (irregular heartbeats).
Withdrawal from cocaine can result in severe mood depression, impacting emotional stability.

Nicotine and Caffeine

Nicotine acts primarily by stimulating the release of dopamine and norepinephrine, affecting pleasure and alertness.
Caffeine withdrawal symptoms typically include fatigue and headache, indicating a reliance on its stimulating effects.
Nicotine toxicity can lead to respiratory paralysis, a serious condition affecting breathing.
