Tissue and content samples were collected from jejunum, ileum, caecum and colon from pigs killed at 2, 3 and 6 h after dosing. Intramuscular administration resulted in significantly higher concentrations in plasma, intestinal tissue and lymph nodes at 2 h but not at 3 or 6 h compared with p.o. administration. The absorption and distribution phase was longer after oral administration, and maximum concentrations in tissue and plasma were determined later than after i.m. administration. No difference between route of administration was observed in the intestinal content. Enrofloxacin concentrations in faeces during a 5\u2010day dosing regimen with i.m. and p.o. administration were determined by both HPLC and bio\u2010assay. Higher concentrations were found after i.m. administration during the first day, but the difference was not significant after 2\u2003days. The biologically active concentrations determined by bio\u2010assay constituted 48\u201375% of the total concentrations determined by HPLC. On the basis of these results it was concluded that in order to ensure an immediate high concentration of enrofloxacin, and thereby avoid an initial selection for resistant mutants, the intramuscular route seems to be preferable to the oral route.<\/jats:p>","DOI":"10.1046\/j.1365-2885.2002.00430.x","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T09:24:23Z","timestamp":1047461063000},"page":"335-342","source":"Crossref","is-referenced-by-count":50,"title":["Distribution of enrofloxacin in intestinal tissue and contents of healthy pigs after oral and intramuscular administrations"],"prefix":"10.1111","volume":"25","author":[{"given":"C.","family":"Wiuff","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Lykkesfeldt","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.
