Question

Is an injection of medicine stronger than a pill form?

Answer 1

if the dosage is equal the injection will help you much quicker.

Answer 2

most commonly yes because not all drugs are absorbed orally 100% and some go through what is called first pass metabolism by the liver (stuff absorbed in the intestines goes straight to the liver first thing before going to the rest of the body, and the liver is often a player in clearing drugs from the body) when taken orally, but some drugs have near 100% bioavalibility and arent affected by liver metabolism so they would be about equal
