This is my list of drugs to memorize, instead of learning drug names i use a different approach, I decided just to be able to identify the drug classes by reading the name. Check the Quizlet. Below it’s just the database for the Quizlet.
Perfect 👌 Here’s your ultimate GI + Respiratory + IBD/IBS + Myasthenia Gravis master list rewritten cleanly in your preferred format:
