Both Levitra and Erec are used to treat erectile dysfunction in men. They both belong to the class of phosphodiesterase-5 (PDE5) inhibitors, but they differ in their active ingredients and some pharmacological properties, such as speed of action, duration of effect, and potential side effects.
Levitra Tablets Ingredients
Levitra tablets contain the active ingredient vardenafil. Vardenafil works by increasing blood flow to the penis during sexual stimulation. It does this by inhibiting the PDE5 enzyme, which breaks down cyclic guanosine monophosphate (cGMP), a substance that dilates blood vessels in the penis. Vardenafil is known for its relatively rapid onset of action.
Erec Tablets Ingredients
Erec tablets contain the active ingredient sildenafil. Sildenafil also works by inhibiting the PDE5 enzyme, which leads to increased blood flow to the penis during sexual stimulation. Sildenafil, the original active ingredient in Viagra, is considered effective, but it may take slightly longer to start working for some men than vardenafil.
