I am just finishing up the didactic portion of my medic program, and this may sound stupid, but one of the ways a couple classmates and I found that helped was to use the actual drug name to help jog your memory.
For example,
Amiodarone
The m looks like a sideways 3, so it reminds me that the initial dose (for a pulseless pt) is 300mg.
Atropine
The "trop" reminds me of "stop", so I remember atropine is indicated for symptomatic bradys, heart blocks, PEA, asystole and organophosphate poisoning.
And for dosing, 0.5 if alive, 1 if done, 2-3 O.P.P. (Org.phos. poisoning)
haha, I don't know if this makes sense to anyone else, but we got pretty creative with them and it lead to some pretty interesting study sessions. Disclaimer: this only a way to help get the initial basic grasp of the drugs and remembering them for quizzes. DO NOT rely on these word games to get you through school and/or internships.
Also, like everyone else has been saying, take the time to actually understand what each drug does and how it works and why you are giving it. I was really good at regurgitating the info on the quizzes, but as class progressed, I had realized I actually made it worse for myself and couldn't relate the words on the page to an actual scenario, let alone remember anything but the most recent drugs. So be sure to go back and review the previous drugs as well.
Just my 2 cents.
Good luck!!!
