Tadacip (Tadalafil) is a PDE5-inhibitor, which means it inhibits the function of an enzyme called as phosphodiesterase type five (PDE5). When PDE5 is reduced, the body spontaneously increase the level of Nitric Oxide and cyclic Guanosine Monophosphate. These potent chemicals boost blood circulation throughout the system, including the male reproductive organ. Sufficient amount of blood enters the erectile tissues and make the spongy organ stiffer during sexual stimulation.
The effect of this drug remains up to 36 hours in the body. This means you can achieve stronger and durable erections after every sexual stimulation during that specific period. Because of this pharmacological action of Tadalafil, it is commonly referred as the “weekend” pill.
