Vidalista 10 is a medication used to treat erectile dysfunction (ED). Its active ingredient is tadalafil, which is a type of phosphodiesterase type 5 (PDE5) inhibitor. By inhibiting this enzyme, tadalafil helps increase blood flow to the penis during sexual stimulation, leading to an erection. Vidalista 10 can interact with certain medications and health conditions, so it's important to discuss your full medical history with your healthcare provider before starting this medication.
