Full drug detail

Overview

N-Acetylcysteine (NAC) is a mucolytic agent commonly used in veterinary medicine to help pets manage certain medical conditions. Its primary use is in treating acetaminophen toxicity, but it also has applications for respiratory disorders due to its ability to break down mucus.

How It Works

NAC works by replenishing glutathione levels and breaking down disulfide bonds in mucus, making it less viscous. This action helps in detoxifying harmful substances and clearing airways.
