Why are some medications pills and some injection? How do the researchers determine which is best?

635 views

For example I take three different types of medication for migraines. One is a monthly injection, one is a dissolvable pill and another is just a regular pill I take. How do the researchers decide the best way for patients to take the pills?

Also I am terrible at chemistry so if anyone’s explanation includes that, please dumb it down as best as you can.

In general, injections are better in that more of the drug actually gets to what it is supposed to do. A large portion of the drug you take orally as a pill gets discharged of by the liver right after being digested. So pills put more strain on your liver for the set amount of effect. On the other hand, all injections run a small risk a trauma or infection, so they have their downsides too. This balance of upsides and downsides is what matters when choosing the form of medicine to use.
