Hi I have had RSD or Causalgia and CRPS Type 1 and 2 since 1968 ,since I was just a kid I followed my Prescriptions exactly I still do so I am Medication Dependent ,an addict can't control their medication and often Self Mediicate i.e Alcohol ,Crank etc ,
For me Avinza Morphine is the best I take a large dose and it doesnt last 24 hours so I take it 3 times a day .
I was in a study a couple years back on the OXYMORPHONE ER it helped but wasnt for me Endo makes it here is more info

Oxymorphone ER is a semi-synthetic mu-opioid agonist that has been formulated as a 12-hour extended-release tablet using Penwest Pharmaceuticals' proprietary time-release technology, TIMERx(R) delivery system. Oxymorphone ER has been studied in a wide range of chronic pain conditions, including low back pain, osteoarthritis pain, post-surgical pain and cancer pain. Oxymorphone ER is currently under review by the FDA. The safety and efficacy of oxymorphone ER have not been established by the FDA.

Oxymorphone IR has been studied in post-surgical pain in doses varying from 5 to 20 mg. Oxymorphone IR is currently under review by the FDA. The safety and efficacy of oxymorphone IR have not been established by the FDA.

Oxymorphone is a Schedule II controlled substance.

Respiratory depression is the chief hazard from all opioid agonists including oxymorphone preparations. Respiratory depression is a particular potential problem in elderly or debilitated patients as well as in those suffering from conditions accompanied by hypoxia or hypercapnia when even moderate therapeutic doses may dangerously decrease pulmonary ventilation. The most common adverse reactions reported by patients treated with oxymorphone ER during clinical trials were nausea, constipation, dizziness, pruritus (itching), vomiting, somnolence, increased sweating, sedation and headache.

I had taken Opana which was Endo's 5 and 10 mg which I'm guessing will be the Breakthrough on the ER
I wish everyone the Best
