This is partially the correct answer. Another thing is trying to keep the medicine as physically small as possible. Pill size is incredibly important as the larger a pill is the less likely it is that people will take their medicine. Really that’s a huge thing in pharma. Also smaller sizes keep shipping costs down, saving .1 grams per dose doesn’t seam like a lot but when you are manufacturing millions of doses a year it adds up.

Dude super easy questions, that can be solved by a 4s google search and 1 click of the button deserve a downvote. Like you don’t even have to open a link just click on one of the “people also ask” things and the question is answered.
