Tadalafil, often recognized by its brand name Cialis, is a prescription medication primarily utilized to address erectile dysfunction (ED) and the symptoms associated with benign prostatic hyperplasia (BPH). In addition to these uses, tadalafil may also be prescribed for the treatment of pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the vessels supplying blood to the lungs. As a member of the phosphodiesterase (PDE) inhibitor class of medications, tadalafil works by relaxing muscles and increasing blood flow to specific areas of the body.
This action enhances circulation, particularly in the penis during sexual arousal, thus aiding men in achieving and maintaining an erection. It is vital to mention that tadalafil does not offer protection against sexually transmitted diseases.
