Tadalafil is a well-studied phosphodiesterase type 5 (PDE5) inhibitor, widely recognized in vascular biology research and pharmaceutical development. Its distinguishing feature is a long half-life (~36 hours), which provides extended pharmacokinetic properties and makes it valuable for formulation research compared with other PDE5 inhibitors such as Sildenafil and Vardenafil.
As a high-purity API (≥99%), Tadalafil is supplied primarily for laboratory research, formulation development, and pharmaceutical manufacturing. With its established role in nitric oxide signaling pathways and smooth muscle relaxation studies, it remains a key material for researchers, formulation scientists, and clinical developers.
