oxycodone hydrochloride, available 5mg, 10mg, 15mg, 20mg, and 30mg. The Only Difference Between These Two Medications that I see is the: inactive ingredients. Small Example: (Oxycodone) contains: magnesium stearate, microcrystaline cellulose, silicon dioxide and stearic acid, and numerous D&C, FD&C colors. (Roxicodone) contains sodium starch, glycolate, corn starch, lactose, and a few of the same that the Oxycodone contains.
