1. Basic information of drugs

1、pharmacological effects

- Tadalafil is an inhibitor of phosphodiesterase type 5 (PDE5). PDE5 is mainly found in smooth muscle cells of the corpus cavernosum of the penis. Under sexual stimulation, the nerve endings release nitric oxide (NO). NO activates guanylate cyclase, increasing the synthesis of cyclic guanosine monophosphate (cGMP). cGMP relaxes smooth muscles, and blood flows into penile tissue to cause erection. Tadalafil inhibits PDE5 and reduces the degradation of cGMP, thereby enhancing erectile function.

2、scope of application

- It is mainly used to treat erectile dysfunction (ED) in men, but can also be used to treat lower urinary tract symptoms caused by benign prostatic hyperplasia (BPH), in which case it helps improve symptoms such as dysuria.
