Vidalista 80 is a medication primarily used to treat erectile dysfunction (ED). Its active ingredient is Tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil works by relaxing the smooth muscles in blood vessels, leading to increased blood flow to the penis, which helps in achieving and maintaining an erection. Vidalista 80 mg contains 80 mg of Tadalafil per tablet. The full chemical composition includes not only the active ingredient but also excipients such as microcrystalline cellulose, hydroxypropyl cellulose, croscarmellose sodium, magnesium stearate, and titanium dioxide, which are used to form the tablet and aid in its stability and absorption. The formulation is designed to provide a longer-lasting effect, with the drug's action lasting up to 36 hours.
