NAPLEX Practice Exam 2025 – Comprehensive Test Preparation

Question: 1 / 1820

What does Probenecid do besides its main action as a Uricosuric?

Decreases insulin levels

Increases beta-lactam levels

Probenecid is a medication known for its main action as a uricosuric agent, which means it increases the excretion of uric acid in the urine. In addition to this primary effect, Probenecid is also known to increase beta-lactam levels. This is important to note because Probenecid can inhibit the renal tubular secretion of some antibiotics, such as penicillins, leading to higher serum levels of these medications when they are taken concomitantly with Probenecid. This interaction can be beneficial in certain situations where higher antibiotic levels are desired for increased efficacy.

The other options are incorrect:

A. Probenecid does not decrease insulin levels.

C. Probenecid does not lower cholesterol.

D. Probenecid does not reduce sugar absorption.
