Vidalista tadalafil, a phosphodiesterase 5 inhibitor, works by increasing blood flow to the penile area and relaxing the smooth muscles in that region. It helps achieve and maintain an erection, but only when there is sexual stimulation present. The active component of Vidalista tadalafil, 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 30 to 60 minutes after ingestion and lasting up to 36 hours. Vidalista tadalafil can be taken with or without food, as well as a small amount of alcohol. Observe your physician's guidance regarding the amount and timing of this medication.
