Given that Vidalista 80 mg is a specific medication, tadalafil is probably its active ingredient, just like in other Vidalista 80 mg formulations. Tadalafil is a PDE-5 inhibitor used to treat erectile dysfunction in males. If you are considering using Vidalista 80 mg or if you currently have a prescription for it, I suggest getting accurate and up-to-date information by speaking with a doctor or pharmacist. They can provide in-depth details regarding the medication, including dose, directions for use, side effects, and interactions with other medications.
