Brief Summary

The purpose of the study is to compare the pharmacokinetics of naltrexone following i.v. and oral administration in healthy volunteers, and to assess the bioavailability of naltrexone following oral administration. Moreover, safety is assessed.

Conditions

Keywords

Infusions, Intravenous; Safety; Pharmacokinetics; Naltrexone; Administration, Oral

Outcome Measures

Primary Outcomes (1)

• Evaluate the pharmacokinetics of naltrexone following i.v. and oral routes of administration in healthy volunteers, and to assess the absolute bioavailability of naltrexone following oral administration.

Secondary Outcomes (1)

• Assessment of safety. Vital signs, Physical examination, clinical laboratory tests, and electrocardiogram were performed at screening and study termination. Additionally, vital signs were recorded on Days 1 and 2 of both treatment periods.

Interventions

Naltrexone HCl. DRUG
