I am a pharmacist and a licensed pharmacist. My personal experience is: anatomy, organic chemistry, inorganic chemistry, biochemistry, materialization, pharmacology, pharmacy, pharmaceutical ingredients and medicalization, all of which are very important. If you learn anatomy well, you will be relatively eager to learn pharmacology, because if you understand the human body structure, you can understand the mechanism of action of drugs. In a word, I think this topic is very important. For example, organic chemistry and inorganic chemistry are the basis of drug delivery.
