Do injectable drugs go through the liver?

Metabolism. After a medicine has been distributed throughout the body and has done its job, the drug is broken down, or metabolized, the M in ADME. Everything that enters the bloodstream — whether swallowed, injected, inhaled or absorbed through the skin — is carried to the body’s chemical processing plant, the liver.

Do intravenous injections bypass the liver?

Intravenous administration bypasses absorption barriers. It is potentially the most hazardous route of administration as a high concentration of drug is delivered to organs as rapidly as the rate of injection, which may elicit toxic effects.

A pill is usually absorbed into the blood through the stomach walls after it is swallowed – these can become active in a few minutes but usually take an hour or two to reach the highest concentration in the blood. IV drugs are injected directly into the blood work much faster – sometimes in seconds or minutes.
