Your answer can be found on this website for the active ingredient Oxymorphone Hydrochloride, but chemically it contains the following. All this can be found in PDR. It contains the following inactive ingredients: lactose monohydrate, magnesium stearate, and pregelatinized starch. The 5mg tablets also contain FD&C blue No. 2 amluminum lake and the 10mg contain D&C red No. 30 aluminum lake... these just make them the colors that they are. There are some differences in the chemical make-up in the ER version of the medication. This list for that version is as follows: hypromellose, iron oxide black, methylparaben, propylene glycol, silicified microcrystalline cellulose, sodium stearyl furarate, TIMERx-N, titanium dioxide, and triacterin. Each MG dosage also contains the ingredient to make the color similar to the non-ER version of this medication... you can also find information like this on their website. The following is the link to the Opana ER website where you can find more information about the product... http://www.opana.com/hcp/opana-er.aspx . I hope this answered your question and not over answered it.
