Pharmacokinetics and Bioavailability of Hydromorphone Following Intravenous and Oral Administration to Human Subjects

Abstract: In a relatively small pilot study, the half-life of elimination of hydromorphone in six subjects was 2.64 +/- 0.88 hours and the drug had a high volume of distribution, 1.22 l./kg. In addition, the drug was rapidly but incompletely absorbed after oral administration. An equation to predict the plasma concentration of hydromorphone on oral administration was developed from the data of these six subjects.

“…Hydromorphone is absorbed by first-order kinetics after both oral and rectal administration with biphasic absorption; an initial phase (up to 2 h) of fast absorption, followed by a slower phase [80]. Absorption is mainly from the upper small intestine [107]. Peak plasma levels coincide with analgesia.…”

“…The Council of the League of Nations appointed a committee to consider the advantages and disadvantages of hydromorphone compared with other opioids [29,66]. The pharmacokinetics in humans following intravenous and oral administration were first studied in 1981 [80,107]. This article is based on a review of the human and animal literature published in English (Medline search 1965-1999, using "hydromorphone" and a combination of "hydromorphone" and "cancer" and "hydromorphone" and "pain" as keywords).…”

“…Oxycodone and hydromorphone have moderate intestinal permeabilities with a bioavailability of 60-87% and 62%, respectively, whereas oxymorphone has a low bioavailability of 10% (11,14,15). Atenolol and metoprolol experiments were carried out to evaluate alcohol effects on low and high permeability drugs, respectively (16).…”

“…Although plasma concentrations of hydromorphone have been studied in humans using high performance liquid chromatography (HPLC) (7) and radioimmunoassay methods (12,20), little is reported about the relationship between concentrations and pharmacodynamic effects of the drug.…”
