Pharm Flashcards
Precursor of 6-mercaptopurine
Azathioprine
Antibody that binds CD3 on T cells
Muromonab
Antibody that binds IL-2 receptor on activated T cells
Daclizumab
Inhibits inosine monophosphate dehydrogenase
Mycophenolate mofetil
Inhibits calcineurin–>loss of IL-2 production–> blockage of T cell differentiation and activation
Cyclosporine
Metabolized by Xanthine Oxidase, therefore allopurinol increases its toxicity
Azathioprine
What are the main actions of Captopril?
ACE inhibitor
- decrease Angiotensin II
- lower GFR by preventing constriction of efferent arterioles
- Prevents inactivation of bradykinin (vasodilator)
What are the main AE of ACE inhibition?
“Captopril’s CATCHH”
- Cough (due to increased bradykinin)
- Angioedema (contra in C1 esterase inhibitor deficient pts)
- Teratogen
- Creatinine increase (due to decreased GFR)
- Hyperkalemia
- Hypotension
Why is Captopril contraindicated in pts with bilateral renal artery stenosis?
ACE inhibitors will further decrease GFR, leading to renal failure
What antibiotics are safe in pregnancy?
Penicillins and aminopenicillins Piperacillin Cephalosporins Macrolides (erythromycin, azithromycin) Metronidazole Nitrofurantoin
What are the two low potency typical antipsychotics?
Chlorpromazine, Thioridazine
What is the typical AE of the low potency typical antipsychotics?
Anticholinergic AE
What are the typical AE of high potency typical antipsychotics?
EPS, Tardive dyskinesia, NMS

Are the (+) or (-) symptoms of schizophrenia easier to treat?
Positive symptoms are easier to treat
Name 5 Atypical antipsychotics
Clozapine Olanzapine Quetiapine Risperidone Aripiprazole
How do the adverse affects of the atypical antipsychotics differ from the typical antipsychotics?
Fewer EPS, LEss anticholinergic AE (atypicals used preferentially over the typicals!)
-WEIGHT GAIN

Atypical antipsychotic
Drug class: Olanzapine
Atypical antipsychotic
Drug class: Quetiapine
Atypical antipsychotic
Drug class: Risperidone
Atypical antipsychotic
Drug class: Aripiprazole
Atypical antipsychotic
Which class of antipsychotics work better on the negative symptoms of schizophrenia?
Atypicals. Atypicals still have greater effect on the positive symptoms however
What are the three drugs used for treating Tourette syndrome???
Fluphenazine (High potency typical antipsychotic)
Pimozide (High potency typical antipsychotic)
Tetrabenazine (degrades DA)
What affect does DA have on prolactin release? What affect would this have on a patient taking an antipsychotic drug?
DA inhibits prolactin release
D2 receptors antagonists can lead to amennorhea or galactorrhea (due to increased prolactin secretion)
What receptors do low potency neuroleptics have effect on?
Block D2 DA receptors
Block Muscarinic receptors
Block alpha 1 receptors –> hypotension
Block histamine receptors –> sedation
What are the symptoms of Neuroleptic malignant syndrome?
Muscle rigidity–>Hyperpyrexia–>Myoglobinuria–>Delirium–>ANS instability
How do we treat NMS?
Dantrolene, Bromocriptine (DA agonist)
What receptors do the atypical antipsychotics have effect on?
Block DA receptors
Block serotonin receptors
Block alpha receptors (hypotension)
Block Histamine receptors (Weight gain, sedation)
What disorders are Atypical antipsychotics used to treat?
Mania disorders
Bipolar disorder
Refractory depression
Anxiety disorders
Which atypical antipsychotic has the highest risk of Weight gain (and diabetes as a result)?
Olanzapine
