Tadalafil 20 mg is a generic prescription drug used to treat pulmonary arterial hypertension, erectile dysfunction (ED), and lower urinary tract symptoms associated with prostate enlargement (benign prostatic hyperplasia or BPH). Tadalafil is only available as a tablet and is administered orally once daily, with or without food. Tadalafil is available as a generic drug as well as two well-known brand-name drugs, Cialis and Adcirca. Cialis is available in tablet dosages suitable for erectile dysfunction and enlarged prostate. Adcirca comes in strengths suitable to treat pulmonary hypertension.
Tadalafil is a PDE5 inhibitor, which stands for “phosphodiesterase type 5 inhibitor.” These drugs relax the smooth muscles in blood vessels, particularly arteries, causing them to widen. This reduces blood pressure in the pulmonary arteries, thereby alleviating pulmonary hypertension, and increases and prolongs blood flow to the penis, thereby improving men’s sexual function. PDE5 inhibitors also relax bladder and lower urinary tract muscles, which aids in the relief of urinary symptoms in men with prostate enlargement.
