Tadalafil, the active ingredient in Tadalista and Cialis, does not directly keep you hard but rather facilitates the ability to achieve and maintain an erection when sexually stimulated. Tadalafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which results in increased blood flow to the penis during sexual arousal. This enhanced blood flow helps to produce and sustain an erection sufficient for sexual activity.
It is important to understand that tadalafil does not cause an erection on its own. Sexual stimulation is necessary for it to be effective. The medication helps the natural process by which an erection occurs, making it easier to achieve and maintain one when aroused.
The effects of tadalafil can last up to 36 hours, which means that during this period, the ability to achieve an erection may be improved with sexual stimulation. However, this does not mean that you will have a continuous erection for 36 hours; rather, it means that you will be able to achieve an erection more easily during this time frame when you are sexually stimulated.
If you experience an erection that lasts longer than four hours, which is a condition known as priapism, it is essential to seek immediate medical attention, as this can cause permanent damage to the penis. As always, use tadalafil as prescribed by your healthcare provider and discuss any concerns or questions with them to ensure safe and effective use of the medication.
