Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor commonly marketed under the brand name Cialis, primarily used for the treatment of erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). It enhances blood flow by relaxing smooth muscles in the blood vessels, particularly in the pelvic region. Maintaining the pharmaceutical purity of Tadalafil is essential to ensure its therapeutic effectiveness, minimize adverse effects, and meet regulatory standards. Impurity profiling plays a vital role in identifying and controlling unwanted substances that may arise during manufacturing, storage, or degradation. Here are some of its known impurities listed below.
