Tadalafil, the main active ingredient in Vidalista 80, comes in an 80mg dosage. This PDE-5 drug is one of the most often recommended drugs for treating ED in middle-aged men. It is also available in lower dosages. Men with erectile dysfunction are the main patients for this medication. Vidalista 80 helps relax the muscles and promotes a hard and long-lasting erection during sexual stimulation by boosting blood flow to the genital region. One Vidalista 80 mg is taken orally, ideally half an hour before sexual activity, along with a glass of water.
