The objective of this study was to determine the plasma concentrations and pharmacokinetic parameters of voriconazole after single\u2010dose intravenous (i.v.) and oral administration to alpacas. Four alpacas were treated with single 4\u2003mg\/kg i.v. and oral administrations of voriconazole. Plasma voriconazole concentrations were measured by a high\u2010performance liquid chromatography method. The terminal half\u2010lives following i.v. and oral administration were 8.01\u2003\u00b1\u20032.88 and 8.75\u2003\u00b1\u20034.31\u2003h, respectively; observed maximum plasma concentrations were 5.93\u2003\u00b1\u20031.13 and 1.70\u2003\u00b1\u20032.71\u2003\u03bcg\/mL, respectively; and areas under the plasma concentration vs. time curve were 38.5\u2003\u00b1\u200311.1 and 9.48\u2003\u00b1\u20036.98\u2003mg\u00b7h\/L, respectively. The apparent systemic oral availability was low with a value of 22.7\u2003\u00b1\u20039.5%. The drug plasma concentrations remained above 0.1\u2003\u03bcg\/mL for at least 24\u2003h after single i.v. dosing. The i.v. administration of 4\u2003mg\/kg\/day voriconazole may be a safe and appropriate option for antifungal treatment of alpacas. Due to the low extent of absorption in alpacas, oral voriconazole doses of 20.4 to 33.9\u2003mg\/kg\/day may be needed.<\/jats:p>","DOI":"10.1111\/j.1365-2885.2008.01030.x","type":"journal-article","created":{"date-parts":[[2009,5,18]],"date-time":"2009-05-18T15:47:02Z","timestamp":1242661622000},"page":"235-240","source":"Crossref","is-referenced-by-count":9,"title":["Pharmacokinetics of voriconazole after single dose intravenous and oral administration to alpacas"],"prefix":"10.1111","volume":"32","author":[{"given":"H.
