Explanation
A. Morphine administered intravenously bypasses the gastrointestinal tract and liver, avoiding the first-pass effect entirely.
B. Diphenhydramine in tablet form is absorbed through the gastrointestinal tract and undergoes significant first-pass metabolism in the liver, affecting its bioavailability.
C. Famotidine in tablet form is also subject to first-pass metabolism, which can reduce its effectiveness.
D. Nitroglycerin sublingual tablets are designed to bypass the first-pass metabolism by being absorbed directly into the bloodstream through the mucous membranes.
E. The same applies to nitroglycerin 10mg sublingual tablets; they also avoid the first-pass effect due to sublingual administration.
F. Acetaminophen is taken orally and undergoes first-pass metabolism in the liver, which can significantly affect its overall bioavailability.
