How It Works
Tadalafil is a selective inhibitor for cyclic guanosine monophosphate that prevents the degradation of cGMP molecules.
cGMP is synthesised in response to nitric oxide release during sexual stimulation. Increased levels of cGMP result in the relaxation of smooth muscles in the corpus cavernosum with increased blood flow to penile regions, giving rise to a hard and long-lasting erection during sexual activity.
Research has shown that it has a different structure than PDE-5 inhibitors like Sildenafil 100 mg ( Cenforce 100mg )and Vardenafil that impact its pharmacodynamics and safety.
It is 9000 times more selective for PDE-5 enzymes that enables it a safer pharmacological profile and suited for patients experiencing increased side-effects with other PDE-5 inhibitors like Sildenafil.
The increased selectivity decreases the risk of side effects involving other organs, especially visual disturbances and cardiovascular symptoms.
