Comparative Study to Evaluate KADIAN and Avinza in Healthy Adults

A Phase IV, Comparative, Randomized, Double Blind, Single-Dose, 2-way Crossover Study to Evaluate the Pharmacokinetics and Safety of Alpharma Branded Products Division (KADIAN)and Ligand Pharmaceuticals Inc. (Avinza) 30 mg Morphine Sulfate Sustained-Release Capsules in Healthy Adult Volunteers Under Fed Conditions

The primary objective of this study was to compare the single-dose relative bioavailability of Alpharma Branded Products Division (Kadian®) and Ligand® Pharmaceuticals Inc. (AVINZA®) 30 mg morphine sulfate sustained-release capsules in healthy adult volunteers under fed conditions.

The secondary objective of this study was to evaluate the adverse events associated with each of these 2 different morphine sulfate modified-release commercial formulations
