Background

Tadalafil is a prescription drug that increases blood flow by relaxing the smooth muscles of blood vessel walls. This relaxes facilitates improved circulation in some areas of the body, particularly where it's required during exercise or intimacy. Under the brand name Cialis, tadalafil is primarily prescribed for treating erectile dysfunction (ED) in men to facilitate and sustain an erection during sexual intercourse. It is also given to men who suffer from benign prostatic hyperplasia (BPH), leading to a prostate enlargement and symptoms such as frequent urination or slow urination. There's also another form of this drug, Adcirca, which is used to treat pulmonary arterial hypertension (PAH), a type of high blood pressure that affects the lungs. In such circumstances, tadalafil is used to enhance physical endurance and enhance the ability of an individual to exercise.
