Normal BMI, erosion of enamel, Russel’s sign, swollen cheeks, rectal prolapse are signs of what eating disorder
Bulimia
Low bmi, amenorrhea, emaciation, bradycardia, hypotension, inverted t wave, prolonged qt, swollen cheeks, Russell’s sign are symptoms of what eating disorder
Anorexia
What enzyme is clozapine metabolized by
CYP1A2
Enzyme inducers (tobacco, tegretol) can ____________ the serum level of other drugs.
Decrease
Enzyme inducers:
Start smoking = ________ dose
Stop smoking =_________ dose
Increase
Decrease
Enzyme inhibitor effect on serum levels of other drugs that are substrates of that enzyme- causing toxic levels.
InDucers DECREASE levels of drug
Inhibitors cause HIGH levels
Older adults are more sensitive to psychotropics because:
Decreased intracellular water
Decreased protein binding
Decreased muscle mass
Decreased metabolism
Increased body fat
Liver disease affects liver enzyme activity and first-pass metabolism, possibly resulting in:
Toxic Plasma drug levels
Mnemonic for inducers:
BS CRAP GPS induces rage
Barbiturates
St. John’s wort
Carbamazepine
Rifampin
Alcohol
Phenytoin
Griseofulvin
Phenobarbital
Sulfonylureas
Plus cigarette smoking
Mnemonic for inhibitors:
SICK FACES. COM
Sodium valproate
Isoniazid
Cimetidine
Ketoconazole
Fluconazole
Acute alcohol
Chloramphenicol
Erythromycin
Sulfonamide
Ciprofloxacin
Omeprazole
Metronidazole
Affects attention and focus, mood regulation, sleep wake cycles, memory formation, fight or flight, reacting to stressful stimulants
Produced in locus coeruleus and medullary reticular formation
Contributes to Anxiety, depression, nightmares
Norepinephrine
Produced in raphe nuclei of brain stem
Regulates mood, appetite, sleep, memory, learning.
Disorders: depression, anxiety, ocd
Serotonin
Produced in substantia nigra (motor movements), nucleus accumbens( addiction) and ventral tegmental area
Reward and pleasure, motivation, movements.
Imbalances are associate with psychosis and addiction.
Disorders: schizophrenia, bipolar, addiction, and depression
Dopamine
Produced in basal nucleus of meynert
Involved with memory, learning, muscle movement
Deficits associated with cognitive decline
Disorders: dementia and Alzheimer’s
Acetylcholine
Most abundant inhibitory neurotransmitter.
Calming, reduces neural excitability. A decrease in this neurotransmitter increases anxiety
Disorders: anxiety, epilepsy, addiction
GABA
Most abundant excitatory neurotransmitter- increases levels increase anxiety
Cognitive function such as learning, memory, mood disorders
Disorders: schizophrenia, depression, bipolar
Glutamate
Which lobe is responsible for executive function (working memory,reasoning, planning, prioritizing, sequencing, insight, flexibility, judgment, impulse control, etc…
Problems lead to personality changes, emotions, and intellectual changes

TSH, creatinine, pregnancy, ecg (if over 50)
Symptoms of __________can mimic mania
HypERthyroid
Endocrine side effects of lithium
Hypothyroid, weight gain
CNS side effects of lithium
Fine tremor (coarse with toxicity), fatigue, cloudiness,headaches, nystagmus
Dermatological effects of lithium
Maculopapular rash, pruritis, acne
G/I side effects of lithium
N/V/D, cramps, anorexia
Renal side effects of lithium
