anticholinergic effects (i.e.: urinary retention, blurred vision)
ADR of ritalin
insomnia (don’t take after noon), anorexia
best antipsychotic to use in Parkinson pts

best antipsychotic for pt with prostatic hypertrophy
haloperidol (low in anticholinergic side effects)
most common side effect of sildafinil (impotence)
MI
cardiac side effect of TCA
