Tadalafil, also known by its brand name Cialis, is a prescription medication utilized in the treatment of erectile dysfunction (ED) and symptoms associated with benign prostatic hyperplasia (BPH). Moreover, tadalafil may be indicated for pulmonary arterial hypertension (PAH), a severe condition characterized by elevated blood pressure in the arteries supplying the lungs. As a phosphodiesterase (PDE) inhibitor, tadalafil serves to relax muscular tissues and enhance blood flow to targeted areas of the body.
By facilitating increased circulation, tadalafil can significantly improve blood flow to the penis during periods of sexual arousal. However, it is important to clarify that tadalafil does not provide protection against sexually transmitted infections.
