Mechanism of cns stimulants
Increase catecholamine, such as NE and dopamine availability at the synaptic cleft
Inhibiting reputable of NE and dopamine, further increasing their bioavailability
Methylphenidate
ADHD
Methamphetamine
Weight loss
Side effects cnS stimulants
Abuse and addicitivity
MOA CNS stimulants
Increase catecholamine at synaptic cleft via direct release from stored vesicles leading to increased NE and dopamine bioavailability is by inhibiting their reputable
Methylphenidate (Ritalin)
ADHD and ADD
Off labels uses include obesity, lethargy and depression
Methtamphetamine
Controlled CNS stimulant for obesity
Off label are narcolepsy and depression
CNS stimulants potential for abuse
These drugs are often abused for recreational use and can be highly addictive
CNS stimulant indications
ADHA obesity and narcolepsy
___ are CNS stimulants that promote NT release and enhance neuronal excitation.
Amphetamines
MOA CNS stimulants
Bind to adrenergic receptors that normally attach to NT, such as NE, E, and Dopamine
Why wouldn’t one recommend CNS stimulant for weight loss
Abuse and addiction
Amphetamine
Controlled CNS stimulant for ADHD and obesity
Off label narcolepsy and depression
Methylphenidate (Ritalin)
ADHA ADD obesity
CNS stimulant and narcolepstt
Amphetamine activate the CNS and cause feeling of wakefulness and alertness to counteract tiredness
CNS stimulants and obesity
Weight loss bc reduce appetite
CNS stimulants and ADHS, “drug holidays”
Don’t take on weekends bc concern with growth as kids
Let them grow
What do CNS stimulant bind to
Adrenergic receptors that normally attach to NT NE, E, D.
Side effects of CNS stimulants
Euphoria, talkativeness, insomnia, hypertension, tachycardia, psychosis, anorexia
Why CNS stimulant and hypertension
Mimic effects of NE in the blood vessels and cause excessive vasoconstriction that may develop hypertension
CNS stimulant and tachycardia and dysrhythmias
Mimic NE, increase HR, Av conduction and force contraction
Psychosis and CNS stimulants
Schizophrenic symptoms
CNS stimulants and anorexia
Loss of appetite
CNS stimulants and tolerance
Develops with chronic use as body adopts to the effects of CNS stimulants, the patient may increase the dosage and frequency to yield desired euphoric effect
CNS stimulants and abuse/dependence

Amphetamine and euphoria
Increased energy and sharpened mental alertness
Increased mental agility and muscular power
What methods of administrationsof amphetamine slower onset of euphoria? What causes quick euphoria
Snorting oral
Smoking IV
Mydriasis and amphetamine
Prevent reputable of NE
Increased levels of Ne bind adrenergic receptors and causes pupillary dilation or mydriasis
Amphetamine overdose causing seizure may be treated with what
Benzodiazepines, such as lorazepam
How treat amphetamine toxicity
Ammonium chloride which acidified the urine and traps the amphetamine, which is slightly basic int he urine to be excreted from the body
Ammonium chloride
Causes acidification of urine which keeps weakly basic amphetamines in a charged state preventing them from being reabsorbed into the body
Ammonium chloride causes _ of the urine which keeps weakly basic amphetamines in a charged state preventing them from being reabsorbed into the body
Acidification
Cocaine
Potent central nervous system stimulant that stimulates behavioral and psychomotor agitation.
Symptoms of cocaine abuse
Euphoria, delusions, mydriasis, hallucinations, agitation , hypertension, cardiac arrhythmias, and hyperthermia which may result in seizure activity. Nasal septum perforation
Cocain and mydriasis
Overstimulat the sympathetic and parasympathetic nervous system and activate the muscles to initiate the fight or flight response
Cocaine seizures and increase in bp cause what
Seizures
MI, intracranial hemorrhage
