Study Notes
Drug Administration Routes
-
Immediate Systemic Effects: Intravenous (IV) administration is the primary route for achieving rapid systemic effects, allowing drugs to enter the bloodstream directly and act quickly.
-
Localized Effects: The topical route is most commonly utilized for localized effects, delivering medications directly to the area of application, minimizing systemic absorption.
-
Slowest Onset of Action: Oral administration generally has the slowest onset of action since it requires digestion and absorption through the gastrointestinal tract before reaching systemic circulation.
-
Drug Delivery into the Bloodstream: Intravenous (IV) administration involves delivering a drug directly into a vein, which allows for immediate and controlled effects.
-
Bypassing First-Pass Metabolism: Routes known for bypassing first-pass metabolism include sublingual (under the tongue) and intravenous administration, allowing drugs to avoid initial hepatic processing and maximize bioavailability.
