Male erectile dysfunction can be treated with Vidalista CT 20. This kind of medicine is a great alternative to tablets. Tadalafil inhibits PDE-5. It increases blood flow to the area during erotic stimulation by relaxing the blood vessels in your penis. This promotes the growth and maintenance of a firm, erect penis that is appropriate for intercourse. It can be taken either with or without food. You must take it exactly as prescribed by your physician. The recommended waiting time before having sex is between 30 to 60 minutes. If you get a painful erection that lasts more than 36 hours, it is advised that you stop using the product and see your doctor right away.
