Well... Did you have any luck? No stress, I'm just eager to see some credible values on oxymorphone bioavailability by different routes of administration. As you say, they're not easy to find.
A reference to the paper would do just fine. Or simply the title. I've got access to full-text journals at work, and I could pull it from MedLine myself.
These were the best I could find. They're old, but you might find them interesting anyway:
Beaver WT, Feise GA. "A comparison of the analgesic effect of oxymorphone by rectal suppository and intramuscular injection in patients with postoperative pain." J Clin Pharmacol 1977, 17(5-6):276-91
Hussain MA, Aungst BJ. "Intranasal absorption of oxymorphone." J Pharm Sci 1997, 86(8 ):975-6.
