How Tadalafil Affects Patients
Tadalafil helps treat erectile dysfunction by increasing blood flow to the penis. It also helps reduce blood pressure in the blood vessels of the lungs for people with PAH and may help reduce the size of the prostate and related urinary symptoms in people with BPH. It is less likely to cause visual side effects than other drugs that help treat ED.
How Tadalafil works in the body
Tadalafil is an effective drug for treating erectile dysfunction, pulmonary arterial hypertension, and benign prostatic hyperplasia. It works by increasing the signaling of nitric oxide and cyclic guanosine monophosphate (cGMP) in the body. This signaling relaxes smooth muscle cells, allowing blood to flow more freely and produce an erection. In pulmonary arterial hypertension, tadalafil relaxes the muscles of the arteries, reducing pressure and easing symptoms. In benign prostatic hyperplasia, it reduces inflammation and tissue remodeling, which can help improve urinary flow. Tadalafil has a
