Why do hospitals prefer injecting medications than offering pills?

Question

Some background : I was in the hospital recently for a couple of days and was able to talk and walk.. however, the doctors prescribed injections and IV canulisation over asking me to pop antibiotics and anti gastric medication. Is there a specific reason for hospitals to prefer it or is it just a matter of convenience?

Answer 1

Because medications injected directly into the bloodstream are going to get absorbed at a much faster rate taking only seconds to take effect whereas a pill has to be swallowed, then digested then absorbed in the body.
