The mechanism of action of tadalafil is similar to that of other phosphodiesterase inhibitors, including sildenafil (Viagra), vardenafil (Levitra), and vardenafil-containing drugs. Tadalafil is an inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). It competitively inhibits PDE5 and is a competitive inhibitor of PDE5. It competitively enhances the effect of cyclic adenosine monophosphate (cAMP) in the smooth muscle cell, which is the main pathway for cGMP to form cGMP-cyclic guanosine monophosphate (cGMP-cGMP).
Pharmacodynamics studies have demonstrated that sildenafil, the active ingredient in tadalafil, and vardenafil, the active ingredients in tadalafil, have a statistically significant (p<.001) positive effect on cGMP levels in the rat corpus cavernosum. Tadalafil has no effect on cGMP levels after oral administration.
Both sildenafil and vardenafil have no effect on cGMP levels after oral administration.

•Introduction
Tadalafil, a phosphodiesterase type 5 inhibitor, has been approved by the Food and Drug Administration (FDA) for the treatment of erectile dysfunction (ED). Erectile dysfunction (ED) is a common condition that affects approximately 2% to 5% of American adults in the United States. ED is the inability to achieve or maintain an erection sufficient for satisfactory sexual performance and can lead to considerable distress, interpersonal difficulty, and increased risk of injury and mortality. The prevalence of ED is higher among men who use sexual enhancement drugs (SEDs), such as sildenafil and vardenafil, and is increasing significantly worldwide. Despite the increasing number of patients with ED, there is still limited data regarding the effect of these drugs on sexual function in the adult male population. This study aimed to determine whether sildenafil, vardenafil, and tadalafil, with regard to sexual function in adult male patients with ED, have a positive effect on sexual function after oral administration.
This randomized, double-blind, placebo-controlled clinical trial was conducted at the National University Hospital of China, Sichuan University, Chengdu, China between January and December, 2021. Subjects were recruited from 3 hospitals in Sichuan Province, China and received sildenafil (n=9) or vardenafil (n=9) once daily for 12 weeks. Subjects received either tadalafil (n=9) or vardenafil (n=9) once daily for 24 weeks. The secondary efficacy measures included changes in sexual function domain scores, the erectile function domain scores, and the International Index of Erectile Function (IIEF) domain scores. Results showed that sildenafil, vardenafil, and tadalafil significantly improved sexual function domain scores compared with placebo after 24 weeks of treatment. Tadalafil was also associated with a significantly increased IIEF domain score compared with placebo.
Findings
The primary efficacy measure was the IIEF domain score, which showed that the sildenafil, vardenafil, and tadalafil significantly improved the sexual function domain scores compared with placebo after 24 weeks of treatment. The IIEF domain score demonstrated a significant (p<.001) positive effect on sexual function domain scores compared with the placebo. The erectile function domain score demonstrated a significant (p<.001) positive effect on sexual function domain scores compared with the placebo. There was no significant difference in the changes in sexual function domain scores between the groups after 24 weeks of treatment.
The results showed that tadalafil, vardenafil, and tadalafil significantly improved the IIEF domain score compared with placebo after 24 weeks of treatment.
