CNS Stimulants Dr. Iszard Flashcards
ADHD stimulant medications 3 types
- Amphetamine, Dextroamphetamine (Methamphetamine)
- Lisdexamfetamine (pro-drug)
- Methylphenidate, Dexmethylphenidate
ADHD NON-stimulant medications 3 types
- Atomoxetine
- Guanfacine
- Clonidine
Stimulants for ADHD
- MOA
- Isomers and thier efficiency
- Block reuptake of NE > DA > 5-HT (non-catacholamine sympathomimetics) + INCREASE RELEASE of NT
- Dexa- isomers (D-isomers) more CNS activity
Methylphenidate MOA And how it is different
BLOCK reuptake of DA
= not increasing release of anything
General Side effects of Stimulants for ADHD
- Low apetite + reduced growth
- Insomnia
- Anxiety, jittery
- Irritability, agitation (psychosis, mania, vocal tics with high doses
- Higher BP/HR
- N,V, Headache
RARE side effects of Stimulants for ADHD
- Priapism
- Seizures (lowers conculsive threshold)
- Sudden caridac death, like in cocain (another CNS stimulant) = do history and PE
- Stroke MI
- Chemical Leukoderma = daytrana patch
5 types of administratons for Stimulants for ADHD
- Immediate release (IR)
- Extended release (ER)
- Long Acting (LA)
- Controlled delivery (CD)
- Oral Disintegrating Tablet (ODT)
RISKS of Stimulants for ADHD
- CVD due to increased BP
- Anxiety
- HTN
- Glaucoma
- Motor tics = like Tourettes
- Mania / psychosis = not treated
- Seizures
- Substance abuse
Stimulants for ADHD IMPORTANT THING for risks and side effects
Its VERY patient dependent individually variable with dose and drug and administration type and person

- Methylphenidate HCL / Metadate = capsule
- Methylphenidate HCL / QuilliChew = chewable tablet
- Methylphenidate Quillivant XR = Liquid
Non-Stimulant ADHD medications
1. MOA
- Increase NT transmission
= Atomoxetine ——> block NE reuptake
= Clonidine + Guanfacien ——> CNS a2 AGONIST (cortical pyramidal cells promoting PFC funcitonal connectivity)
Non-Stimulant ADHD medications
- Onset time
- Used for who
- Schedule
- 1-4 weeks
- Pt intolorant to stimulation effects, parents that dont like to give child stimulant (severe adhd given stimulant will calm down, no as high euphoric effect) USUALLY for child and preadolescents

How can you clinically manage teh drugs
You can give patient short acting (IR) for days they only need to get some things done and drug for long acting (ER) for days they need to get a lot done or all day need to be in control
= minimize time under drug as much as you can
