Intravenous administration bypasses the gastrointestinal tract. It delivers the drug directly into the bloodstream.
Antagonists block receptor activity. They prevent other substances from binding to receptors and activating them.
The FDA (Food and Drug Administration) is responsible for approving drugs before they can be marketed in the USA.
