Drug therapy = Most likely to result in adverse effects and toxicity in older adults Absorptions = Altered due to gastric ph being less acidic and slowed GI functions in older adults. Distributions = Affected by lower total body water percentages, increased fat content, and decreased liver protein production in older adults. Excretion = Affected by decreased glomerular filtration rate and decreased number of nephrons causing drugs to be cleared less effectively. Signup and view all the answers
