Vidalista 40 is a medication used to treat erectile dysfunction (ED), a common condition in men characterized by the inability to achieve or maintain an erection during sexual activity. The active ingredient in Vidalista 40 is Tadalafil, which belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors.

Tadalafil works by relaxing the blood vessels in the penis, allowing increased blood flow to facilitate an erection when sexually stimulated. It does not cause spontaneous erections; sexual arousal is still necessary for the medication to be effective.
The recommended starting dose of Vidalista 40 is usually one tablet taken orally with water, about 30 minutes to an hour before anticipated sexual activity. The effects of Vidalista 40 can last for up to 36 hours, which is why it's often referred to as the "weekend pill."

Fildena 150 is a medication containing sildenafil citrate, which is primarily used to treat erectile dysfunction (ED) in men. Sildenafil citrate is the active ingredient in Cenforce 200, and it works by increasing blood flow to the penis, helping men achieve and sustain an erection when sexually stimulated.
Cenforce 200 belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. It inhibits the enzyme phosphodiesterase type 5, which regulates blood flow in the penis. By blocking this enzyme, Cenforce 200 helps relax the blood vessels in the penis, allowing increased blood flow, which leads to an erection.
