Infant serum and urine were also obtained for drug concentrations. DP 450 mg tid resulted in peak maternal serum concentrations of 4.0 \u03bcg\/mL and 2.2 \u03bcg\/mL for DP and NMD, respectively. Breast milk concentrations averaged 1.06 and 6.24 times the serum levels for DP and NMD, respectively. No DP was measurable in the infant's serum except for cord blood, which contained 0.7 \u03bcg\/mL DP, 26 percent of simultaneous maternal concentration, and 0.9 \u03bcg\/mL NMD, which represented 43 percent of the maternal concentration. Infant urine collected over an eight-hour period contained 3.3 \u03bcg\/mL of DP and 3.7 \u03bcg\/mL of NMD.<\/jats:p>","DOI":"10.1177\/106002808902300112","type":"journal-article","created":{"date-parts":[[2017,5,30]],"date-time":"2017-05-30T06:17:09Z","timestamp":1496125029000},"page":"56-57","source":"Crossref","is-referenced-by-count":3,"title":["Disopyramide and N-Monodesalkyl Disopyramide in Serum and Breast Milk"],"prefix":"10.1177","volume":"23","author":[{"given":"Allan J.","family":"Ellsworth","sequence":"first","affiliation":[{"name":"Departments of Pharmacy Practice and Family Medicine, Schools of Pharmacy and Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John R.","family":"Horn","sequence":"additional","affiliation":[{"name":"Department of Pharmacy Practice, School of Pharmacy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vidmantas A.","family":"Raisys","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, School of Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lea Ann","family":"Miyagawa","sequence":"additional","affiliation":[{"name":"Departments of Nursing and Ambulatory Services, University of Washington, Seattle, WA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Judy L.","family":"Bell","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, School of Medicine, University of Washington, SmithKline Bio-Science Laboratories, Waltham, MA."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,5,30]]},"reference":[{"key":"bibr1-106002808902300112","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-96-3-337"},{"key":"bibr2-106002808902300112","doi-asserted-by":"publisher","DOI":"10.1177\/000331978303400601"},{"key":"bibr3-106002808902300112","doi-asserted-by":"publisher","DOI":"10.1038\/clpt.1985.131"},{"key":"bibr4-106002808902300112","doi-asserted-by":"crossref","first-page":"346","DOI":"10.1016\/S0090-9556(25)06354-8","volume":"6","author":"KARIM A","year":"1978","journal-title":"Drug Metab Dispos"},{"key":"bibr5-106002808902300112","doi-asserted-by":"publisher","DOI":"10.1185\/03007997909109400"},{"key":"bibr6-106002808902300112","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2125.1982.tb01985.x"},{"key":"bibr7-106002808902300112","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2125.1985.tb02731.x"},{"key":"bibr8-106002808902300112","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2125.1986.tb02845.x"},{"key":"bibr9-106002808902300112","doi-asserted-by":"publisher","DOI":"10.1093\/clinchem\/26.2.197"},{"key":"bibr10-106002808902300112","doi-asserted-by":"publisher","DOI":"10.1002\/jps.2600741010"},{"key":"bibr11-106002808902300112","doi-asserted-by":"publisher","DOI":"10.2165\/00003088-198005010-00001"},{"key":"bibr12-106002808902300112","unstructured":"Physicians' desk reference.
