vidalista 80 is primarily prescribed to men with erectile dysfunction (ED). It contains sildenafil, an inhibitor of phosphodiesterase type 5 (PDE5) that helps sustain an erection during sexual stimulation by increasing blood flow to the genital area. To take vidalista 80 is simple. Allow the tablet to completely dissolve in a glass of water approximately half an hour before going to bed. For best results, try not to crush or break the tablet.
