Tadalafil, the active component of the drug Vidalista, is frequently prescribed to treat erectile dysfunction (ED). Vidalista 20 can be a safe and useful treatment for ED when used as prescribed and under a doctor's supervision. The active component of Vidalista, tadalafil, is an inhibitor of phosphodiesterase type 5 (PDE5). It functions by boosting blood flow to the penis during erotic stimulation, aiding in the development and maintenance of an erection. This mechanism of action has been well investigated and has demonstrated efficacious treatment outcomes for ED.
