Vidalista 5 works by increasing blood flow to the penis and the smooth muscles around the penile area. It can only help achieve and sustain an erection in the presence of sexual stimulus. Tadalafil, the active component of Vidalista 5, inhibits the PDE5 enzyme, which is responsible for erection production. Erections might happen and endure longer by stopping it from working. After intake, this medication takes 30 to 60 minutes to start working. Vidalista 5 can be taken with or without food and in moderation in combination with alcoholic beverages. Take this pill as directed by your physician, both in terms of dosage and timing.
