Italian Stallion 120mg pills contain Sildenafil citrate as their key active component, belonging to the PDE-5 inhibitor category. For men suffering from erectile dysfunction, taking a single pill approximately an hour before engaging in sexual activity can prevent the breakdown of CGMP by inhibiting the activity of PDE-5 enzymes. Typically, during sexual arousal, a man’s body releases nitric oxide, leading to the formation of cGMP. An accumulation of cGMP in the male genital area’s corpus cavernosum allows the blood vessels to widen, enhancing blood flow to and within the male genital organs, resulting in stronger erections. Detailed instructions regarding the medication’s duration of effectiveness are available on its packaging.
