Get the bundle of Anesthesia Constellation from Skyscape or just AnesthesiaDrugs as a stand-alone program.
For each drug, it includes:
Use
Dosing
Elimination routes
How Supplied
Storage (for some reason)
Pharmacology
Pharmacokinetics
General Guidelines / Precautions
The neat thing is that the submenus are listed on the right side of the screen by a single letter (U, D, E, H, S, Ph, Pk, and G) and you don't have to go through all the above information. You can shoot directly to the Pharmacology by hitting the Pk button after you bring up the drug you want.
A most excellent program.
