Long acting opioids include MS Contin, Kadian, Avinza (these are morphine based), Butrans patch
is worn for 7 days), Fentanyl patch
is worn for 48-72 hours - this is the long acting medication that I use and I find it extremely effective), Opana ER (oxymorphone), Exalgo (hydromorphone). I have also tried MS Contin and Opana ER. Fentanyl Transdermal has been the most effective and consistent pain medication for me compared to the others I have tried.
