Oxycodone vs fentanyl

Is this a school assignment? If you're posting these, it's generally appreciated for you to give your thoughts and then ask for feedback, rather than ask for a whole answer.

I'll give you a freebie this time- Think about the main adverse effects of narcotics, generally that's going to be respiratory depression, right? The action of fentanyl is fast on and then fast off. We give it for acute pain, and in ICU settings it can be seen as an infusion for pain management. Oxycodone is going to be longer onset of action but also longer duration. You're less likely to experience respiratory depression with the oral agent than the IV. That could be one thing they're looking for.

Oxycodone is an oral drug. It can't be given to someone who is in NPO. 

Yeah, people around here get pretty cranky sometimes when students ask questions or try to get information. Tread carefully on that. This is an unreliable resource generally, because you don't know the real identities of the people who are posting here. You see graduate students posting surveys that they are basing studies off of.

When I was young, and I asked my mother the definition of a word, she would advise me to look it up in the dictionary. That way I learned how to use a resource, get totally reliable information, and be self-reliant.
