Reply to comment by CardiOMG in When pharmaceutical companies develop new prescription drugs, do they test every method of delivery to the human body? For example, injected, orally, topically, rectally, etc? by scottyboy218
Most drugs have a delivery dependent on molecule type. Most „small molecules“ are delivered orally as they can pass through the intestinal walls and are not denatured whereas big molecules (for example antibodies) would be denatured in the gut and hence rendered useless which means they are generally injected. Another thing to consider is pharma cocinnetics but in the end you will never be able to use a big molecule drug in a pill to be swallowed
