Men with erectile dysfunction can be treated with medications such as Vidalista Professional. Tadalafil is the active ingredient in Vidalista Professional. It belongs to the class of medications known as phosphodiesterase type 5 inhibitors. By inhibiting PDE-5, Vidalista Professional supports sustained smooth muscle relaxation and improved blood flow, helping to sustain elevated levels of cGMP in the penis. This procedure is required during sexual stimulation to achieve and maintain an erection. Take this pill as directed by your physician, both in terms of dosage and timing. Don't shatter, chew on, or crush it. Vidalista Professional should be taken with food. Keep out of the reach of minors.
