Comparison of One Morphine Sulfate Sustained-Release 200 mg Capsule With Two 100 mg KADIAN Capsules on Applesauce

Study Overview
=================
Brief Summary
-----------------
The objective of this single-dose, open-label, randomized, two-period crossover study was to compare the rate of absorption and oral bioavailability of a test formulation of morphine sulfate 200 mg sustained-release capsules manufactured by Alpharma Branded Products Division Inc. to an equivalent oral dose of the commercially available reference product, KADIAN 2 x 100 mg capsules manufactured by Alpharma Branded Products Division Inc. when administered as a sprinkle on applesauce after a 10-hour overnight fast.

Has used any over-the-counter (OTC) medication including vitamins, within 7 days prior to the first dose of study medication without evaluation and approval by the study investigator. Has used any prescription medication, except hormonal contraceptive or hormonal replacement therapy, within 7 days prior to the first dose of study medication without evaluation and approval by the study investigator. Has been treated with any known enzyme altering drugs such as barbiturates, phenothiazines, cimetidine, carbamazepine, etc., within 30 days prior to the first dose of study medication. Has smoked or used tobacco products within 60 days prior to the first dose of study medication. Has a history of substance abuse (including alcohol) in the past 5 years. Is a female with a positive pregnancy test result. Has a positive urine screen for drugs of abuse (amphetamines, barbiturates, benzodiazepines, cocaine, cannabinoids, opiates).
