How does Sildenafil Ratiopharm work?

The active substance in Sildenafil ratiopharm, sildenafil, belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the enzyme phosphodiesterase, which normally breaks down a substance called cyclic guanosine monophosphate (cGMP). During normal sexual stimulation, the penis produces cGMP which causes relaxation of the spongy muscles of the penis (corpora cavernosa), allowing the influx of blood into the corpora cavernosa and producing an erection. By blocking the breakdown of cGMP, Sildenafil ratiopharm restores erectile function. Sexual stimulation is always required to achieve an erection.
