Oxycodone Vs. Morphine (bio Availability Question)

Joseph twang Says:


I understand oxycodone is 1.5x stronger than morphine, but does that take the oral bioavailability into account?

I've seen someone say 20mg of oxycodone is equivalent to 30mg of morphine, but is that taking into account that only 30% of the morphine is absorbed by the body whereas with oxycodone it's about 80%

So when taking 30mg of morphine you're body is really only getting about 9mg but when taking 20mg of oxycodone you're getting 16mg of it absorbed into your body.

I think I am going to be switched from 30mg of Morphine to 10mg of Oxycodone, in terms of bioavailability that means instead of my body getting 9mg of morphine, I'll be getting 8mg of oxycodone instead. Will this be as effective?
