text: Yo, check it out, here's the deal
  We evaluated four methods, keepin' it real
  To calculate gentamicin sulfate dosage right
  In 96 patients, we brought the light
  
  Comparin' 'em all to the individualized way
  We got the pharmacokinetic parameters, okay?
  Gentamicin's serum concentration time data on the line
  Helped us calculate dosages, one of a kind
  
  We used the "predictive methods" for a test
  Sarubbi-Hull, Dettli, "rule of eights," and Chan, we're blessed
  We calculated doses with each method's might
  But some patients got subtherapeutic or toxic, not right
  
  Dettli and Chan showed therapeutic concentrations, true
  More than Sarubbi-Hull and rule of eights, that's the view
  But the individualized method, it took the crown
  More patients reached therapeutic levels, hands down
  
  But yo, listen up, here's the catch
  With the predictive methods, we had to match
  Serum concentration checks and dosage adjust
  To ensure early therapeutic levels, we must
  
  So remember, when it comes to dosage selection
  Serum concentration determinations, no exception
  Predictive methods can give a clue
  But for precision, individualized is what we pursue
