Alfuzosin is a medication used to treat benign prostatic hyperplasia (BPH) in men. As with all drugs, it may contain impurities that can affect its purity, stability, and efficacy. Alfuzosin impurities may include degradation products, residual solvents, and other contaminants. The presence of these impurities can impact the quality and safety of the drug, which is why it is important to monitor and control their levels during the manufacturing process.
