# Ascorbic Acid Prevents Efavirenz-Induced Anxiety-Like Behavior and Brain Oxidative Stress in Zebrafish

## TL;DR

This study shows that ascorbic acid can prevent anxiety-like behavior and brain damage caused by the HIV drug efavirenz in zebrafish.

## Contribution

The study demonstrates that ascorbic acid mitigates efavirenz-induced anxiety and oxidative stress in zebrafish brains.

## Key findings

- Efavirenz treatment induces anxiogenic-like behavior in zebrafish.
- Ascorbic acid prevents efavirenz-induced oxidative stress in the brain.
- AA treatment reduces adverse CNS effects of efavirenz in a preclinical model.

## Abstract

Efavirenz (EFV) is a medication widely used for the treatment of HIV-positive patients. Several studies have demonstrated that the prolongate use of EFV can lead to the development of neurological diseases, such as panic syndrome, depression, and anxiety disorders. In this current study, we evaluate whether the ascorbic acid (AA) treatment can prevent anxiety-like behavior and brain oxidative stress induced by EFV treatment in zebrafish. Our data demonstrated that the EFV treatment induces anxiogenic-like behavior and intense lipid peroxidation in the zebrafish brain. The AA treatment was able to prevent both anxiogenic-like behavior and brain oxidative stress elicited by the EFV treatment. Therefore, our data provide robust evidence that the EFV induced anxiety-like behavior in zebrafish via a redox-dependent pathway and that AA treatment can minimize these adverse effects. Taken together, our preclinical study strongly suggests that the use of an AA-enriched diet can minimize the effects of EFV on the central nervous system (CNS) and improve the quality of life for patients undergoing EFV treatment.
