Student question re Isoflurane

Hello, I'm an ADN student that will be observing in the OR soon and part of my assignment is to look up drug info (dose, onset/peak/HL, nursing implications etc...) on some commonly used medications in the OR. Isoflurane is not in my drug guide and I'm having a hard time finding the specific info I need by doing a general search on-line. Does anyone know of an on-line drug reference site I can use that would have anesthesiology meds (specifically Isoflurane) with this type of info available?
