Tadalafil, commonly recognized by its brand name Cialis, is a prescription medication utilized for treating erectile dysfunction (ED) and relieving symptoms associated with benign prostatic hyperplasia (BPH). Additionally, it may be prescribed for pulmonary arterial hypertension (PAH), characterized by elevated blood pressure in the vessels responsible for transporting blood to the lungs. Tadalafil functions as a phosphodiesterase (PDE) inhibitor, promoting relaxation of muscles and enhancing blood flow in certain areas of the body.
By facilitating improved circulation, tadalafil effectively aids in increasing blood flow to the penis during episodes of sexual stimulation. However, it is essential to understand that tadalafil does not offer protection against sexually transmitted infections.
