| pubmed-article:7081500 | pubmed:abstractText | Fourteen patients receiving routine doses of amitriptyline developed plasma drug concentrations above 300 ng/ml. Of the 7 patients with plasma levels above 450 ng/ml, 6 developed a drug-induced delirium as opposed to none of the 7 with levels below 450 ng/ml. Thus, this adverse effect could be avoided by monitoring levels and reducing dosage when appropriate. | lld:pubmed |
