Question

An oral drug that is water soluble

a. should be taken with fatty foods.
b. requires active transport for absorption.
c. will readily diffuse into the GI tract.
d. must be taken on an empty stomach.

Answer 1

A water-soluble oral drug will readily diffuse into the GI tract without the need for active transport or fatty foods for absorption.

Step-by-step explanation:

An oral drug that is water soluble will readily diffuse into the GI tract. Water-soluble nutrients are typically absorbed by simple diffusion. Most water-soluble vitamins, like most B vitamins and vitamin C, enter the absorptive cells (enterocytes) directly, without the need for active transport or the presence of dietary fats. Unlike fat-soluble vitamins, they do not need to be taken with fatty foods to enhance their absorption. Therefore, an oral water-soluble drug generally does not require special conditions like fatty foods or an empty stomach for its absorption.
