Vidalista 20mg, a phosphodiesterase 5 inhibitor, works by promoting blood flow to the penile region and relaxing the smooth muscles there. It helps achieve and maintain an erection, but only when there is a sexual stimulation present. The active component of Vidalista 20mg, tadalafil, inhibits the PDE5 enzyme, which is responsible for erections. Because of its inability to operate, erections can occur and last longer. This medication has a quick onset of action, beginning to work 15 minutes after ingestion and lasting up to 36 hours. Vidalista 20mg can be taken with or without food, as well as a little amount of alcohol. Observe your physician’s guidance regarding the amount and timing of this medication.
