Pharmacology exam study with expert solutions 2025/2026
1.Artelon is a new drug that, when administered intravenously, causes a reduction in
blood pressure. When taken orally, it must be taken with a glass of orange or tomato
juice on an empty stomach and patients must avoid calcium supplements or antacids
within 4 hours of taking the drug. You suspect that the drug is absorbed in:: the
stomach.
If Artelon requires an acid environment for absorption, it must be absorbed
from the stomach. Such drugs are weak acids and must never be taken with
calcium supplements or antacids because these would reduce the gastric
acidity needed for optimal absorption.
2.It is likely that Artelon:: is a weak acid.
Drugs absorbed from the acid environment of the stomach are weak acids.
Weak bases are absorbed from the more alkaline environment (pH 6 to 6.5)
of the intestine. Only nonionized drugs are absorbed.im- portant in
