Raw Tadalafil (Cialis) powder (171596-29-5) Description

Cialis powder, sold under the brand name Cialis powder among others, is a medication used to treat erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension. It is a tablet taken by mouth. Onset is typically within half an hour and the duration is up to 36 hours.

Tadalafil powder, also known as IC351, is PDE5 inhibitor marketed in pill form for treating erectile dysfunction (ED) under the name Cialis powder, and under the name Adcirca for the treatment of pulmonary arterial hypertension.

Penile erection occurs when the penis fills with blood. This happens because the blood vessels that bring blood flow to the penis dilate, increasing the blood supply. At the same time, the blood vessels that remove blood from the penis contract. The blood accumulates in the penis, causing an erection.

When a man is sexually stimulated, nitric oxide is released into the penis. Nitric oxide enables the production of cGMP, which controls the dilation and contraction of the blood vessels that carry blood to and from the penis.

Another substance, PDE5, destroys cGMP. When this occurs, the blood vessels return to their normal size, and the erection ends. Tadalafil powder stops PDE5 from destroying cGMP. This causes the erection to last for longer.

The muscles of the arteries in the walls of the lungs also contain PDE5, which is why the same drug can also help with pulmonary hypertension treatment.
