It’s just fascinating to me. How does a tiny dose of medication going into a large mass of fat get absorbed?
In: Biology
Because there are capillaries leading to every part of your body. That’s why if you get a scratch it bleeds. If a medication is potent and needs to be absorbed slowly, it’s injected like that into adipose tissue. Injecting a medication directly into the blood has it traveling through all parts of the body more or less immediately.
Insulin; epinephrine; and many others all use fatty area injections
It’s easy to find; less painful and provides more “controlled” absorption.
Medicine right into the vein can cause issues being too rabidly avsilable
