简要总结
The purpose of this study was to compare the pharmacokinetic (the way a drug enters and leaves the blood and tissues over time) profile of Dilaudid OROS 16mg (Dilaudid Slow Release; hydromorphone HCL) administered under fasting conditions, following a high-fat breakfast meal. The study also examined the effect of naltrexone blockade on the pharmacokinetic profile of Dilaudid SR.
详细描述
This was a randomized (patients are assigned different treatments based on chance), open-label, three-way crossover study, performed in normal, healthy adults. Each patient received orally administered treatments (a different treatment during each dosing phase): Treatment A: single dose of Dilaudid SR 16 mg administered under fasting conditions without the naltrexone block;Treatment B: single dose of Dilaudid SR 16 mg administered under fed conditions without the naltrexone block, Treatment C: single dose of Dilaudid SR 16 mg administered under fasting conditions with naltrexone HCL 50mg block (3 oral doses of 50mg each administered 12 hours prior to , at the time of, and 12 hours after Dilaudid SR 16mg administration). There was a 7-day washout period between dosing phases.
Venous blood sampling times were 0 (prior to dosing),2,4,6,8,10,12,16,20,24,30,36,42,and 48 hours after each Dilaudid SR administration. LC/MS/MS (Liquid Chromatography/Mass Spectroscopy/Mass Spectroscopy)techniques were employed for the analysis of plasma for hydromorphone concentration. Each patient randomly received orally-administered treatments of single dose of Dilaudid SR 16mg; under fasting conditions without the naltrexone block; under fed conditions without naltrexone block; under fasting conditions with naltrexone 50mg block (3 oral doses of 50mg naltrexone HCL each administered 12 hours prior to, at the time of, and 12 hours after hydromorphone administration); 7-day washout period between dosing phases.
