In the “Selected Examples” section, under Methotrexate, reference 78 should have been cited in the second sentence of the first paragraph as follows:
“Methotrexate is excreted mainly as unchanged drug in the urine, with small amounts excreted in the bile and feces.78”
In the same section, under Busulfan, reference 96 should have been cited instead of reference 60 in the fourth sentence of the first paragraph as follows:
“These findings are supported by results from a study involving 14 children (age 0.5 to 4 years) and 11 older children and adults (age 12 to 54 years), which showed a significant increase in busulfan apparent oral clearance expressed relative to BSA in the group of younger children.96”
In the References section, reference 78 was given as:
78. Rodman JH: Pharmacokinetic variability in the adolescent: Implications of body size and organ function for dosage regimen design. J Adolesc Health 15:654-662, 1994
While it should have been:
78. Schmiegelow K: Advances in individual prediction of methotrexate toxicity: A review. Br J Hem 146:489-503, 2009
Reference 96 was inadvertently omitted and should have been:
